FOA Has Reached An Amazing Milestone - 100,000 Certified Fiber Optic Technicians.
That is a lot of people! 100,000 people equals the population of a city like
Albany, NY (101,228), or almost fill the University of Michigan
football stadium (the largest in the US with 107,601 seats), or just
about equal today's US fiber optic technician workforce (Telecom Line Installers, 102,200 US DoL 2023
statistics.)
And those 100,000 fiber techs hold over 130,000 FOA certifications.
How did FOA achieve this milestone? FOA has been quietly working behind
the scenes to achieve our original goal - developing a competent fiber
optic workforce through education, certification and standards, a
workforce capable of building the world's fiber optic communications
networks. FOA is the certifying body; it is assisted by a worldwide
network of FOA approved training organizations and their FOA certified
fiber optic instructors.
Someone once described FOA as "the biggest professional association you never
heard of." FOA doesn't create a lot of publicity - "fiber to the press
release" it's been called, or fill everybody's inbox with daily emails
touting our work. FOA just works with service providers,
governments, unions, contractors, any and everybody who uses fiber, along with
our worldwide network of schools to create the fiber optic workforce
the world needs.
FOA is also known for its giant knowledge base on fiber optics. More
than a dozen textbooks (plus translations), almost 1,000 web pages of
technical information (about 4 million page views per year) and dozens of free online learning courses at
Fiber U.
And the FOA continues to grow. It took us almost 20 years to reach 50,000 (October 2014)
but only 10 years to double that. FOA continues to grow; the network of
over 220 FOA approved schools worldwide includes some that have been
with
FOA for over 20 years and 25 that have joined us this year.
Pardon us while we take some time to reflect on this milestone and
recognize the people who made it all possible. We also invited some of
the people in the FOA network and others from industry to share their thoughts.
Jim Hayes, FOA President, Editor
I get to start! I'm your editor, Jim Hayes, who along with one other
founder, Eric Pearson, is still active in the FOA and the fiber optic
industry. Both Eric and I have more than 40 years in the industry. My
wife Karen and I manages the FOA and I'm the techie and writer.
What is the "secret" of the FOA's success? There is no
secret! FOA supports the industry and the industry supports FOA. The
people we have in our network are all experts in both fiber optics and
educating workers. Regular readers of this Newsletter know we have been
vigilant, keeping up with our industry, educating our 35,000+ readers
about the changes in the industry and sometimes questioning the hype and
misinformation so prevalent in high tech today.
Eric Pearson, Pearson Technologies
Eric and I both joined the fiber optic industry in its infancy, before
1980. Eric is one of - if not THE - most experienced trainers and an
expert on termination.
This year, the Fiber Optic Association marks its achievement
of 100,000 Certified Fiber Optic Technicians. In addition, the FOA has
issued an estimated 32,000 advanced certifications. The FOA was founded as a result of a shared observation
that most of the difficulties experienced during fiber installation was
due to inadequate experience and knowledge. In many cases, the
appropriate term was not ‘inadequate’, but ‘totally missing’. Each of
the 15 founders had dozens of field ‘horror’ stories that exemplified
this shared observation. These horror stories, a result of missing
essential knowledge and abilities, guided the FOA in creation of the
both the FOA and its certification examinations. Under the leadership of James Hayes, then founder and
President of FOTEC (The Fiber Optic Test Equipment Company), the FOA was
founded to provide the mechanism for certification to identify those
individuals who demonstrate the knowledge and abilities deemed essential
for successful fiber installation. To the end user or manager of a fiber network, the main
benefit of certified personnel is increased installed reliability. To
the manager of an installation organization, this benefit is reduced
installation cost and increased confidence in installed reliability. To
the installer, this benefit is increased confidence in his ability to
perform the installation successfully. Congratulations to the FOA for establishing a widely
accepted and recognized, vendor neutral, certification organization with
more than 220 approved schools world-wide.
John Highhouse. Lincoln Trail College, Retired
John was one of two college professors who were FOA founders. He brought
to the FOA a deep understanding of the education process, helping us
establish the FOA knowledge base and establishing standards for teaching
and testing. John's school, Lincoln Trail College in Illinois is still
an active FOA school!
Congratulations on your great success with the FOA.
I certainly am pleased and excited at how the organization caught
on and continues to thrive. I remember well our first get together when you assembled
all of these experts from across the country and all of the various
disciplines of the field. The debates about methodologies and
procedures were sometimes heated. But the one thing that we all agreed
on was that there needed to be some clear standard for employers to
recognize the title “Fiber Optic Technician “. At that time anyone who could stick on connectors or join
two fibers called themselves a “Fiber Technician “ and this group
decided that there needed to be some standard for that designation. And
The FOA was born.
Bill Graham. Mississauga Training, FOA Director
Bill is known as "Mr. Fiber" in Canada where he has trained thousands of
fiber techs from Toronto to the Arctic. Bill sold his company a few
years ago and retired from training but is active as a member of the FOA
Board of Directors.
I was working as a Master Electrician and teaching Electrical
and Fiber Optics to electrical apprentices at a community
college. Information on Fiber Optics was scarce I received
Fiber Optic training from Bell Labs and Corning. I also connected with
many of the Fiber Optic Pioneers in the Boston area, including Jim and
Karen Hayes. I had so many questions which they answered so readily. I joined the Fiber Optic Association and received my CFOT
#160 in 1998 and FOA Instructor Certification in 2003. For the next 20 +
years I certified hundreds of Technicians through Mississauga Training,
conducting courses across Canada and in Europe. I joined the Board as
the Canadian Director. I was humbled to be a part of this group as they
represented the Fiber Optic industry well and were a great source of
information Fiber Optics has been an exciting part of my life and I
congratulate Jim and Karen Hayes who have committed their lives to bring
this group to 100,000 Certified technicians. This should be
recognized as one of the most significant accomplishments of the
communications industry.
Tom Collins, Techtricians, FOA Director
Tom, like Bill Graham, became involved in fiber from his work in the
electrical trades. Tom has taught fiber optics for the IBEW
apprenticeship program and as a college professor. He is our
"Train-the-Trainer" instructor, teaching many new instructors how to
teach fiber optics the FOA way and a pioneer in using online learning to
enhance training.
Over 20 years ago, I was invited to serve on the FOA
Board of Directors. Since then we have made great strides with
increasing training sites for the Educational Field, Apprenticeships and
the Department of Transportation. As the fiber industry continuously
changes with new technologies, we have our training sites to include lab
instruction on how to use fusion splicers and OTDR’s. We’ve had
great success with incorporating hybrid instruction utilizing our
award-winning web site. Currently we are working on short fiberinars
(webinars) for the Train the Trainer program for prospective
instructors. Two things I can say about the FOA, is we are like family
and treat everyone with respect and we provide the best fiber training
materials in order to be the best in the
field.
TIA (Telecommunications Industry Association), Dave Stehlin, President Most of the founders of FOA met at EIA fiber optic standards
meetings in the mid-1980s ( EIA merged with USTSA to become TIA in
1988). Many cooperated in training programs, culminating in the Fiber U
conferences in the 1990s where they decided to create the FOA.FOA
continues as an active participant in TIA standards committees.
"The Telecommunications Industry Association (TIA)
congratulates the Fiber Optics Association (FOA) on certifying their
100,000th fiber technician," said Dave Stehlin, CEO of TIA. "This
remarkable achievement underscores the FOA's commitment to advancing
fiber optics expertise. By providing technicians with specialized skills
and standards, the FOA is instrumental in addressing the growing need
for skilled professionals. We are thankful for their collaboration in
the Broadband Nation initiative, which is pivotal in cultivating the
next generation of fiber optics experts." Dave Stehlin, CEO of TIA.
Corning Optical Communications
Corning, of course, revolutionized communications with the invention of
low-loss optical fiber in 1970. Siecor, their cabling joint venture with
Siemens, was active in the founding of FOA and Corning has always been a
supporter for FOA.
On behalf of Corning, I want to extend my heartfelt
congratulations to you and the Fiber Optic Association on achieving the
incredible milestone of 100,000 certifications globally. This is a
testament to the FOA’s unwavering dedication to advancing fiber optic
knowledge and elevating standards across the industry. As the Director of Innovation for Hyperscale Data Centers
at Corning, I cannot overstate the importance of the FOA’s
contributions to our field. The comprehensive training, rigorous
certifications, and emphasis on excellence that your organization
champions have significantly enhanced the skills of fiber optic
professionals worldwide. This achievement reflects your vision and
leadership in ensuring the industry is well-prepared to meet the
ever-growing demands of fiber optic connectivity and innovation. At Corning, we are immensely proud of the FOA’s impact
and grateful for the role you play in shaping the future of fiber optic
technology. This milestone is a monumental accomplishment, and we
celebrate it alongside you. Thank you for your dedication and for continuing to inspire all of us who are committed to advancing this critical industry. Marcus Sullivan, Director, Hyperscale Data Center Solutions Corning Optical Communications LLC
Jim Simpson, electrical training Alliance,
When the FOA was founded in 1995, we were already involved with the
apprenticeship and journeyman training programs of the International
Brotherhood of Electrical Workers and National Electrical Contractors
Association. That partnership has continued to this day and thousands of
IBEW members have been trained and certified as CFOTs.
On behalf of the industry and its countless professionals, we
extend our heartfelt congratulations to the Fiber Optic Association
(FOA) for the incredible milestone of certifying 100,000 fiber optic
technicians worldwide. This achievement not only highlights the FOA's
commitment to excellence in fiber optics education but also underscores
its pivotal role in shaping the future of global communications. By
setting a high standard for technical knowledge and practical skills
through the Certified Fiber Optic Technician (CFOT) program, the FOA has
empowered individuals to excel in an industry that is critical to
modern connectivity and innovation. Since 1995, the International Brotherhood of Electrical
Workers (IBEW), the National Electrical Contractors Association (NECA),
and the electrical training ALLIANCE have proudly partnered with the FOA
to advance the training and certification of skilled technicians.
Through this longstanding collaboration, many of our members have
benefited greatly from FOA’s rigorous CFOT certification, gaining the
expertise needed to meet the demands of cutting-edge fiber optic
technologies. The FOA’s focus on hands-on training, combined with its
commitment to adaptability in an evolving industry, has been
instrumental in preparing our technicians for success in a highly
competitive and dynamic field. As the FOA celebrates this landmark achievement, we
commend its dedication to fostering technical excellence and its
enduring partnership with organizations like ours. Together, we look
forward to continuing our shared mission of equipping professionals with
the skills they need to build and maintain the essential fiber optic
networks of the future. Congratulations again to the FOA on this
momentous accomplishment! Jim Simpson, Director of Installer-Technician and Residential electrical training Alliance
Stephen Hardy, Lightwave Magazine
Lightwave Magazine has been the leading publication for fiber optics
ever since it was founded by Howard Rausch in 1983 and for much of the
time led by Stephen Hardy. Conversations with Stephen and news from
Lightwave has been one of the ways FOA keeps up with the fiber optic
industry.
The fact that FOA has now
certified 100,000 fiber-optic techs highlights the organization’s
success in its essential educational role – as well as the fact that it
realized the need for tech certification early in the fiber era. As this
era has progressed, FOA certification has evolved to keep pace with not
only rapidly changing optical technology but with the growing number of
applications the technology must now support. This last point signals that FOA’s work isn’t done. Fiber
networks promise to become the foundation of an even greater number of
services, including some that we presently can only imagine. I expect
we’ll continue to have FOA to thank as we enjoy the benefits future
fiber infrastructures will provide. Stephen Hardy, former editorial director of Lightwave and Broadband Technology Report
And from Lightwave, October 27, 2024: The
FOA is renowned for its rigorous standards and comprehensive
curriculum, which equip technicians with the essential knowledge,
skills, and abilities needed to excel in the field. Tempo Communications attains FOA-approved school status
Patrick McLaughlin, Cabling Installation & Maintenance Magazine
Like, Lightwave for fiber optics, CI&M has always been our source
for news on the premises cabling business and industry standards. We
have always depended on Patrick to help us understand the technology and
business of cabling.
The Fiber Optic Association’s certification programs deliver
no-nonsense training and education that enrich learners with knowledge
that benefits the entire food chain of the fiber-installation process.
Unencumbered by vendor influence, the FOA’s courses of study are backed
by instructors who have lived every scenario imaginable. To me, a
certification from the FOA indicates that a professional has been
instilled with up-to-the-moment technical knowledge coupled with
street-smart-style wisdom they did not have to gain through their own
trial-and-error. Gaining a certification from the FOA benefits a
fiber-optic professional, certainly, but it also benefits that person’s
customers who gain the advantage of the certified professional’s ability
to apply their learning on the jobsite. Patrick McLaughlin Editorial Director, Endeavor Business Media Digital Infrastructure Group
Michael Fong, Director, International Municipal Signal Association (IMSA)
Bill Graham introduced FOA to IMSA because he was training and
certifying members of IMSA in fiber optics. Now FOA and IMSA work
together to train and certify IMSA members who are transportation techs
who work with fiber. Michael was also the first FOA certified instructor
for IMSA.
Congratulations to the Fiber Optic Association (FOA) on
reaching the incredible milestone of offering 100,000 certifications!
This remarkable achievement underscores the FOA's unwavering commitment
to advancing excellence and expertise in fiber optics across the globe.
It has been an honor to be part of this success in collaboration with
the International Municipal Signal Association (IMSA) since 2018, whose
partnership has played a vital role in extending fiber optic knowledge
to professionals in the transportation industry. Together, this
milestone reflects a shared dedication to innovation, quality, and
growth in an ever-evolving industry. I look forward to continued success
and many more milestones in the future! Credit The FOA's Network of Training Organizations
The work of training the fiber optic techs that FOA certifies is done by
a worldwide network of training organizations teaching classes from the
Arctic to Antarctica. These schools partner with FOA to develop our
knowledge base on fiber optics and training curriculum. They deserve
credit for all their work and recognition of their role in reaching this
milestone. We want you to know more about some of them and their
contribution to the FOA.
Several of our longest relationships with schools are with technical
colleges like Lincoln Trail College where founder John Highhouse taught
telco technicians, Los Angeles Trade Tech in downtown LA, and Gateway
Community College where Tom Collins started the fiber program. The
schools in the Kentucky Community and Technical College System helped
train the workers who built "Kentucky Wired" and transformed the state
from the bottom ranking to the top of states in communications. BDI
Datalynk is the king of the "boot camp" training organizations with
instructors traveling around the US teaching at many locations. SIGTECH
in Malaysia has been one of the most active schools for almost two
decades. Etisalat Academy is an example of service providers in the
network. We could go on and on and on, but the FOA schools all deserve credit for FOA reaching this amazing milestone.
Here are comments from a few of them.
Joe Botha, Triple Play Fiber Optics, South Africa
Joe and Triple Play Fiber Optics joind the FOA network in
2006. We like to brag that Joe has trained everybody in fiber optics in
Sub-Saharan Africa. He is also our resident expert on OSP construction
and author of our handbook on the subject.
Heartiest congratulations on this momentous achievement. This accomplishment by The FOA is a testament to the
value proposition that students, companies and the like, reap the
benefits of. As I see it, the recipe for The FOA’s success is by consistently delivering excellence.
Dave Ramsey, Instructor, Marion Technical College, Marion, Ohio In addition to teaching the fiber class at Marion for all
these years, Dave has been instrumental in helping FOA develop
instructor "train the trainer" courses for developing new instructors at
other Ohio technical colleges. After many years of teaching basic premise structured
cabling Marion Technical College added fiber optic cabling to its
curriculum. Shortly after adding fiber optics the college began a review
of cabling certification organizations for the benefit of our
Telecommunications and IT students and in 2012 the FOA was chosen partly
because of its easy access to exceptional training material. Since 2008 numerous students have become FOA
certified and benefited from their certifications in job searches,
actual employment and other educational opportunities. Various companies
have trained their employees via Marion Tech, some for FOA
certification and others to familiarize employees with fiber optic cable
capabilities for their particular industries. Marion Tech has also been
a partner in the certification of FOA certified instructors for various
educational outlets which can provide significant advantages for their
students. Marion Technical College congratulates the
FOA on their 100,000th fiber optic technician certification and looks
forward to working with the FOA in the future for the benefit of our
students and interested companies.
Bee Suat Lim, Director, 100G Training & Consultancy Pte Ltd, Singapore
Bee and Yeo Hock Lai Isaac have been an FOA school since 2009. Besides
providing training in Singapore, they were instrumental in creating the
FOA design textbook.
This milestone of certifying 100,000 technicians underscores
FOA’s unparalleled contribution to advancing fiber optic education and
professional development worldwide. It is a testament to FOA’s
dedication and commitment to all the FOA’s approved schools
internationally. We are honored to be part of this journey. Being part of
the FOA network has been invaluable to 100G Training and Consultancy Pte
Ltd. Since our establishment in 2009, we have been consistently
supported by FOA in our mission to provide world-class fiber optic
training in Singapore. Over the years, we have successfully trained and
certified hundreds of students and industry professionals, equipping
them with the expertise to excel in the ever-evolving fiber optic
landscape. We look forward to continuing our partnership with FOA as
we work together to develop the next generation of fiber optic
professionals.
Randa Tawfik, HitekNOFAL Solutions, Cairo, Egypt Training and certification worldwide are a challenge for any organization. Local partners like HitekNOFAL
in Egypt bring to the FOA organization knowledge of the local language,
customs and markets that can make training fiber techs more relevant
for the companies in the region.
HitekNOFAL Solutions
joined FOA back in 2009. At the time, we were the first company in the
Middle East and North Africa (MENA) region to offer FOA courses
including hands-on training, field exposure, as well as FOA-supplied
technical material. From the very beginning, FOA were quite cooperative
with our training center, fully taking into consideration the
differences in the MENA region. Ever since we started, we faced an extraordinary surge in
training requests across the region, although there were other FO
training schools at the time. Over the years, we added to our curriculum
FOA courses as they were being developed. On our part, being partner with FOA has helped our
company to market itself locally and regionally as one of “the” FOA
experts. It also allowed us to partner with Telecom Egypt and with local
universities in training. Throughout the years, FOA has been enthusiastically
cooperative with us at HitekNOFAL Academy, fully understanding and
coping with cultural differences, as well as with difficulties that some
students may have had with English language.
Ian Gordon Fudge, Fiber DK, Copenhagen, Denmark
We first met Ian at the OFC conference in 2008 or 2009, where he handed
us a copy of his own textbook on fiber optics and told us about his
training programs. He joined FOA shortly after that and has been the
most widely travelled FOA trainer - from the North of Greenland, to
North Sea oil platforms, to Africa and the Middle East. We depend on Ian
for his technical expertise.
My training started many years ago, networks were mostly
4Mbit token ring and the 10Mbit ethernet. But also hand polishing
multimode 3M Hotmelt connecters. In the late 90s I was asked if I would
do a training session- fiberoptics in Jinja Uganda. This changed my
life, a fantastic time training in Jinja, looking out of my hotel window
I had a view of lake Victoria, and the source of the Nile. Returning to Denmark, I developed a 5 day fiber optic
course, the first in Denmark, and everyone told me, nobody will want 5
days of training and how could I fill five days with fiber optics. The
day the training session went public, we had a waiting list of over 100
people. Then training week after week with 16 trainees. A few years
later FTTH was born, and I developed a 5 week course where the trainees
built a town with 350 customers, all up and running 3 cores 2 multimode
for data and one singlemode for CATV. The interest for certifications in Denmark was zero. I
became a FOA member starting a school 733, and in the first years, a few
got certified. It went very slow in the beginning, then there was
interest from the Middle East. I visited several countries, UAE, Jordan,
Lebanon, Oman, Palestine, and many others. The interest for FOA
certifications was growing, and then in 2019 the interest grew very
fast, I have now started a school in Uganda (as this was the first place
I had trained) have now trained in 20 different countries, certified
over 1200, thats over 1% of all FOA certified, this year was awarded the
individual award from the FTTH Council Europe. 20 years ago, I
would ask if the trainees were interested in becoming certified, today I
am asked,"can we become certified?" Today its FTTH, and datacenters ,
and being certified by Anritsu, EXFO, Fluke Networks, Viavi, VeEX,
Prysmian, Ericsson, Emtelle, Condux, OFS, KeyFibre and FOA.
Andy Edwards, Managing Director, CommsLearning Ltd, New Zealand
Andy trains from New Zealand but his courses take him all around the South Pacific. As he says, "Nobody can doubt that the FOA is truly International !"
I thought the attached map might be a good visual of where
I’ve delivered FOA training across the South Pacific. I’ve trained
around 1,700 students and looking forward to hitting 2,000 in the next
year or so.
The South Pacific has many remote places all becoming
connected by fibre, which is why I get invited to Kiribati (Gilbert
Islands), Papua New Guinea, Solomon Islands, Fiji, American &
Western Samoa, Tonga, The Cook Islands and Vanuatu along with the bigger
countries like Australia, New Zealand, Malaysia and Singapore. Nobody can doubt that the FOA is truly International !
THANKS!
FOA offers a sincere "thank you" to the
industry, all the fiber optic technicians, all our schools and
instructors, and anyone we've overlooked for helping make this
achievement possible.
Classroom
Resources For STEM Teachers In K-12 And Technical Schools
Here is the POF kit sent to teachers for demonstration.
Teachers in all grades can introduce their students to fiber
optic technology with some simple demonstrations. FOA has
created a page for STEM or STEAM (science, technology,
engineering, arts
and math) teachers with materials appropriate to their
classes. Fiber
Optic Resources For STEM Teachers.
As FOA celebrates our 100,000th CFOT® certified technician,
introduces the "FOA Badge In Fiber Optics" for others working in the
field and adds new courses at Fiber U which offer a "Certificate of
Completion," it's a good time to explain the differences between them. FOA has created a page to explain the differences in certifications, certificated and badges.
All FOA
Certification Credentials Are Now Online
All FOA Certified Fiber Optic Technicians now have their certification
credentials online. if your FOA certification has not expired you should have been notified you have an
online credential. If you did not get notification it may be because
FOA did not have a valid email for you. Contact FOA to inquire about your certification credential.
And now, introducing a new FOA credential: The "FOA Badge In Fiber Optics"
An industry-wide credential for professionals working in fiber optics FOA is best known as the certifying body for the nearly 100,000 FOA-certified fiber optic technicians
who build worldwide networks. FOA has been asked many times about credentials for other
professionals in fiber optics.
Besides the technicians that design,
build and operate the fiber optic networks the world uses for
communications, there are many other professionals that are essential
for the success of the fiber optic and cabling industries. These
professionals manufacture, sell and distribute fiber optic components or
plan and manage the projects that include fiber optics.
New Fiber U Course: Fiber
Optic Safety Covers Construction And Installation
This
new Fiber U course focuses on safety in fiber optic installation. There are two lessons in this course,
fiber optic construction and fiber optic installation. The dividing
line between the two courses is the installation of the fiber optic
cables. Construction leads up to and/or is completed when the cables are
installed. Installation begins when the fiber tech installs the cable,
then completes the splicing, termination testing and documentation. The
overlap between the two is the installation of the cables where both
construction personnel and fiber optic techs are involved.
Here is the new Fiber U "Fiber Optic Safety" self-study program. Take the course and get your certificate of completion.
We bought one ourselves - it's well made and distinctive.
New Edition of FOA's Basic Fiber Optics Textbook
It has been 5 years since we have updated the FOA Reference Guide To Fiber Optics,
so it is certainly time for an update. The latest version is different
enough we call it a new edition. Many of the updates are for new
technologies which are reshaping the fiber optic industry like coherent
transmission, BI fibers, etc. We've also added a section on the fiber
optic workforce which has much relevance because this book is used to
train those entering the workforce. We've also worked on making the book
more readable, adding formatting that eases reading and a new
comprehensive index.
Inflation was an issue, but the price only goes up $2 to $29.95 for the paperback and $12.95 for the Kindle version.
The new edition of the FOA Reference Guide To Fiber Optics is available from Amazon and booksellers worldwide.
FOA Guide To The Fiber Optic Workforce
- what we've learned in developing the fiber optic workforce over more
than a quarter century and almost 100,000 certified techs.
Telecom, Electrical Jobs Among Top "Launchpad" Jobs
A launchpad job is the term used for jobs that allow achieving career and economic success without a college degree. Groundbreaking research from American Student Assistance and Burning Glass Institute
studied the careers of millions of workers who went directly to work
after high school to identify the Launchpad Jobs that offer the best
chances of long-term success
Almost one in five workers without a degree out-earn the median
college graduate, and around two million nondegree workers earn over
$100,000 per year, according to a new report from the American Student
Assistance® (ASA) and Burning Glass Institute (BGI), two national
nonprofits that focus on advancing data and research on topics related
education and economic mobility. The research, which tracked the career
paths of millions of nondegree workers, found systematic patterns of
success, with the first job out of high school a crucial choice.
The report, “Launchpad Jobs: Achieving Career and Economic Success Without a Degree”
– commissioned by ASA, and conducted by BGI – explores the entry-level
jobs commonly filled by those without degrees and provides
recommendations on how to bridge the information gap in order to ensure
that all young people are aware of the breadth of quality job
opportunities available to them following high school.
Look at Table 4: "Highest-Ranking Stable
Jobs—Those with Decent Pay, High Retention, and Low Automation Exposure
and Unemployment Risk." Telecommunications line installers and repairers and Electrical power-line installers and repairers are both among the highest ranked jobs.
Kuala Lumpur Is The Fastest-Growing City for Data Center Connectivity
Anchoring Kuala Lumpur’s status is a top score of

Reach for the Stars: How Starlink Conquered Latin America
Starlink, the satellite broadband provider
operated by Elon Musk’s SpaceX unit, is making rapid inroads in Latin
America. As of November 2024, Starlink’s services are live in 28
countries/overseas territories in Latin America, with more launches
planned for 2025. Starlink has also made strong progress in the
Caribbean.
According to the map on the Starlink website,
a handful of new LatAm markets are scheduled to go live before the end
of 2024, namely: Suriname, Montserrat, and Antigua & Barbuda.
In 2025, Starlink will make a concerted effort to ramp up its presence
across the Caribbean, where it already claims partial availability.
Countries earmarked for connectivity next year include: Anguilla, Aruba,

Germany suspects sabotage after undersea internet cables are severed
The C-Lion1 cable between Finland and Germany was
severed in the Baltic Sea, its operator said, after damage was reported
to another cable linking Lithuania and Sweden. An underwater
communications cable connecting Finland and Germany was cut Monday
morning, its operator Cinia said, a day after damage was reported to a
separate internet cable linking Lithuania and Sweden, also in the Baltic
Sea. While it was still unclear what exactly happened,
Germany’s defense minister said the cutting of two undersea internet
cables appeared to be deliberate acts of “sabotage.” The incidents are
“a very clear sign that something is going on here,” Boris Pistorius
told reporters in Brussels ahead of a meeting of European Union defense
ministers Tuesday. “Nobody believes that these cables were accidentally
severed.”
FCC Launches First Review Of Submarine Cable Rules Since 2001
The Federal Communications Commission today voted
to launch a major, comprehensive review and update of licensing rules
for submarine cables that transmit information between continents and
fuel economic activity. Since the agency’s last review in 2001, the
technology, economics, and national security environments surrounding
these systems have greatly changed.
Oversight of submarine cables traces back even before the existence of
the Commission itself. The Cable Landing License Act of 1921, Executive
Order 10530 of 1954, and even the Submarine Cable Act of 1888
highlighted the importance of such communications systems and the
importance of securing them. Still today, this infrastructure is vital
to global communications and economic activity. There are 84
FCC-licensed cable systems and, as of December 2022, cable landing
licensees reported more than 5.3 million Gbps of available capacity and
6.8 million Gbps in planned capacity for 2024.
The Commission seeks comment on how best to improve and streamline the
submarine cable rules to facilitate efficient deployment of submarine
cables while ensuring the security, resilience, and protection of this
critical infrastructure.
This is an advertiesement we saw recently. We heard years ago from
AT&T that more than 80% of all phone calls originated from indoors,
not outdoors, so it's no surprise that 90% of all smartphone data is
from devices connected on WiFi. The move for smartphones and other
mobile devices to use WiFI for phone calls and data connections was a
smart move for device makers and service providers alike.

What FOA's Instructors And Technical Advisors Are Telling Us
In the October FOA Newsletter we ran a long illustrated feature article offering
guidelines for aerial cable plant installation, illustrated by some
"excellent" bad examples. That article elicited quite a few comments,
especially from the instructors at some of our FOA schools around the
world, and led to some discussions with others in our field, including
manufacturers. Several topics seem to warrant further discussion, so we
thought it would be interesting to share some of our notes and encourage
more inputs before we cover the topics in detail in future issues of the
newsletter.
Here are some of the topics of the comments. Some, we promise, are controversial! Feel free to comment.
Aerial Cable Plant
Do people still use aerial cable plants? The problems aerial
cables have with weather make them unreliable and not cheaper when they
have to be repaired after damage during disasters. Many areas around the
world are putting all new cables underground.
Some areas don't use messenger wires on aerial cables because of
the problems with lightning strikes. Others complain about the weight of
the messengers causing strain on the poles. They use ADSS cable
instead. ADSS cable is easier and faster to install, even costs less.
Why are ADSS cables still mainly marketed to electrical utilities?
They are popular with utilities because they can be installed closer to
power conductors, but they also make sense if you are installing new
fiber optic cables, especially in rural areas, maybe anywhere.
Who allows cables to be installed with such poor workmanship? Don't the cables get inspected before they are accepted?
Pulling vs. Blowing Cables
Microcables and microducts are becoming more widely used so cables are being blown into ducts not pulled.
Microcables now include cables with more fibers, making them a choice for most installations.
Microducts are easier to install, even possible in currently used
ducts, and easy to include multiple ducts for future expansion.
Microducts are not just for microtrenching. Their small size
allows multiple ducts to be placed when only a single typical duct would
be placed, simplifying the "Dig Once" policy (installing extra ducts
whenever doing underground construction.
Microtrenching vs. Directional Boring
It seems some users prefer directional boring as less disruptive.
Malibu, CA just installed ~7.5 miles (12 km) of duct along the Pacific Coast Highway by directional boring.
Flexible vs. Hard Ribbon Cable
Some cable manufacturers have said traditional hard ribbons are obsolete and future cables will be flexible ribbon cables.
There are so many hard ribbon cables already installed that the need to know how to prepare and splice them will not go away.
Some contractors say they prefer hard ribbons which they claim are are easier to splice.
We've also been told that some flexible ribbons are easier to work with than others. Likewise fusion splicers.
There is a lot there, isn't there? It provides us lots of topics for
investigation and future articles. Should all cables be made like
microcables? Should all cables above a certain number of fibers be
flexible ribbons? Should all aerial cables be ADSS? Who makes the
"best" fusion splicer or other tools? None of these questions have
"black or white" answers, but all merit discussion.
What topics do YOU think should be added to this list? Let FOA Know.
Watch the future FOA Newsletters for more coverage about these issues.
The FlowScout MPO OLTS, which is capable of testing duplex LCs, 8-fiber
MPOs, and 12-fiber MPOs in addition to 16-fiber MPOs and 16-fiber MMCs,
performs the 16-fiber test in 6 seconds.
New Idea For Cable Marking And Identification
Marking cables at patch panels or equipment is
important for making proper connections and keeping documentation up to
date. Most techniques for identification use color codes or printed
labels. A Canadian company has another idea, adding a NFC (near field
communication) chip to the cable and also providing color codes.
PUL-R Technologies Inc.
from Canada, now offers Heli(TM), which is a miniature, fully re-usable NFC
cable tag. The use of NFC as an RFID makes it compatible with any smart
phone which can read NFC tags. The NFC has a non-volatile memory with
60 years of data retention, which allows it to encode circuit
information and optical parameters such as circuit length, insertion
loss, return loss, etc.
While PULR has developed this product for FTTH applications but it
should be highly useful in any application where it can be used to
identify cables at a patch panel or at equipment.
Heli is available for both fiber optic cables and UTP (Cat 5) cables and other cable types. They offer an iOS app for programming and reading the labels.
Singlemode Fiber For Embedded And High Temperature Applications
Fibercore’s range of polyimide coated, bend-insensitive Single-Mode (SM)
fibers are specifically designed for use in harsh environments. The
fibers target micro-seismic ‘fracking’ sensors, distributed temperature
and pressure sensors used in Oil & Gas exploration and process
optimization.
Understanding Fiber Optic Tools
FOA contributor Vladimir Grozdanovic explains
the tools used in fiber optic installation in this new technical paper. Read it in the FOA Guide.
Is It Just The OTDR Or Is Singlemode Loss Really Directional?
Our series of articles on the compatibility and splicing of G.652 and G.657 summarized below and explained fully here raised another question from a knowledgeable reader.
"When you do a bidirectional OTDR test and average, you remove
the backscatter differences. But it seems to me that two fibers of
different MFDs would have an actual directional loss difference, much
like mismatched MM fiber. Do you have any information that addresses
this?"
One of FOA's technical contacts at a fiber manufacturer gave us this explanation. "With singlemode fibers there is simply one mode. The loss is simply the
overlap of the modes in the two fibers and is the same in either
direction since only one mode propagates and all other modes are
cladding modes." So there you have it -
Singlemode splices showing different losses in bidirectional losses are just a artifact of how the OTDR tests
Averaging the loss in the two directions gives the actual splice loss
The actual splice loss the same in either direction.
A Quiet But Important Change In The Fiber Optic Cable You Buy
With so many cable designs today,
like microcables or high fiber count cables, requiring bend-insensitive
fibers, would it make sense to make all or most singlemode fibers as
bend insensitive fiber?
Two manufacturers (Corning and OFS) told FOA the industry is moving towards a G.657.A specification
in fiber, because the industry is moving towards smaller denser cables
in the network & the bend resilience is a requirement for the cable
design. So singlemode fiber is moving to being BI fiber, exactly what happened
with 50/125 laser optimized fibers a decade ago. With most new fiber,
compatibility is not an issue. But it is recommended to check with the
cable manufacturer if you are not sure what fiber is being used in the
cable you are purchasing.

FOA has rewritten the FOA OTDR Trainer around Fiberizer. The Fiberizer PC
software was the version we used for creating the Trainer, but the basic
techniques apply to all versions of Fiberizer. FOA provides a folder of
sample traces in 3 categories - Parameter Traces, Sample Traces and PON
Traces - around which we build the trainer. If you set up Fiberizer,
you can complete the FOA OTDR Trainer lessons and then use the same
software to analyze other traces you may have, even from other brands of
OTDRs, as long as they are .sor files.
The FOA OTDR Trainer is ready to help you learn about OTDRs. Go to the OTDR Trainer page, tech/ref/testing/OTDR/OTDRsimulator.html, choose your version of Fiberizer, download the FOA Traces and you are ready to go.
FOA wishes to thank VeEX
for permission to use their Fiberizer® software in our OTDR trainer.
And our compliments to them for making the ap available on multiple
platforms that ensure anybody can use it.
How Good Are Your OTDR Launch/Receive Cables?
FOA received an inquiry about some OTDR traces that
showed failures. Quite a few fibers failed at the final connection to
the receive cable, indicating that there could be a problem with the
connection - dirt of a bad connector on the receive cable. Have you
checked the connectors on your OTDR - or OLTS - reference cables
recently? You should inspect and clean them regularly - every few
connections - to ensure they are good. If they are bad, they will cause
false failures on the cable under test.
NECA/FOA 301 fiber optic installation standard
withdrawn
The NECA/FOA 301 fiber optic installation standard has been
withdrawn. It's almost a quarter century old and a decade since the
last update. It has been decided the standard needs to be replaced with a
more modern document covering current technology and written in a
format that allows easier updating.
In the meantime, there is lots of useful information in the standard and you can still download a free copy from FOA.
Learning Important Information From A Found Cable Scrap
While walking down the street near the FOA office, we found this cable
laying in the gutter. What a find! A short length of Corning Rocket
Ribbon 864 fiber cable left over from an installation by a contractor.
We brought the cable back to our office with the intention of opening it
up and creating a video about the construction of this modern high
fiber count cable, but something got our attention first. The cable had a
very
long line of printing on it with lots of interesting and useful
information. So before we started deconstructing it, we decided to
photograph the printed information and interpret it. That turned out to
be an important part of the information we learned from the cable. Then,
as you will see below, we dissected the cable and learned even more.
The most common way to track projects is the Gantt Chart, a
chart of activities that tracks the progress of projects along a
timeline. each activity is represented by a bar and the position and
length of the bar represents the starting date and duration of the
activity. This allows you to see what activities are needed for the
project, when the activities start and end so it can be used to track
the progress of the project visually. Here is what a Gantt Chart for a
fiber project might look like:
You might remember an article in the FOA Newsletter in April 2022 or the FOA Guide page on Project Management about the timing of a fiber optic project where we showed the progression of steps in a project like this:
The Gantt Chart is simply this list converted to a Gantt Chart
using a Microsoft Excel spreadsheet. You can download a copy of the FOA Gantt Chart spreadsheet (xlsx file - 16kB)
and use it to create your own Gantt Chart for any project. All you have
to do is to input your own data and change the activity names as
necessary. You can also follow the directions from Microsoft to create your own version.
Help On Color Codes (Including Copper Cabling And Fiber Optics)
The FOA has created a print-your-own pocket guide to fiber
optic color codes. It has
color codes for fibers and buffer tubes, connectors and premises cables
inside and on the back, QR codes to take you directly to the FOA Guide
and Fiber U. The FOA
Guide page on Fiber Optic Color Codes is one of the most read pages on the FOA
website and the Fiber Optic Color Codes minicourse on Fiber U very popular also.
FOA received an inquiry about whether techs
working on restoring OSP links should be concerned about eye safety if
the link used fiber amplifiers. To answer this question, we had to do some research on fiber amplifiers.
The short answer is YES, you should be concerned. The long answer is
more technical and includes details that every OSP tech needs to know.
FOA
has written many articles about loss budgets,
something everyone involved in fiber optics needs to
know and needs to know how to calculate. We've
created a online Loss Budget Calculator that does
the work for you. Just input your cable plant data
and it calculates the loss budget. It works on any
device, especially smartphones and tablets for field
use and even allows printing the results.

Questions/Comments From FOA Newsletter Readers
Is The FOA CFOT® A License?
Q: Can you use a CFOT certification to install fiber and charge for it? Or do you need other licenses as well? ;
A: FOA Certification is considered evidence of competence and
accepted worldwide by many companies, groups, etc. Licenses are a legal
credential required by local authorities to conduct business for
anything from a barber to a truck triver to contractors doing fiber or
other work. Most locales require a license as a contractor which may
require a fiber specialty. You need to investigate this with your local
authorities.
Pulling Fiber Optic Cables In Metal Conduit
Q: Often when constructing fibre, it is encased in steel pipes (e.g. when being attached to buildings or bridges.
I am seeking guidance on a case where the encasement has to make a right
angle (or less) turn. How is the installation done? Considering
possible challenges in duct laying and fibre pushing / blowing
A: The bend radius of the conduit should be kept large to not cause
excess friction on the cable that would require high pulling tension.
Low friction plastic duct can be pulled into the conduit first or cable
lubricant used before the cable is pulled into the duct or conduit.
Radiation Effects In Fiber Optic Cables
Q: We were asked about fiber optic cables in presents of nuclear
radiation in reactors. Will radiation affect the glass fiber?. Is jacket
material affected by radiation?
A: This has been a topic of discussion and study since the first
optical fiber use, first relative to use in nuclear power plants and
nuclear powered subs and ships. Today fiber is used in satellites and
the ISS. Fiber can be sensitive to radiation and is therefore used as a
sensor for radiation in some experiments. Normal fibers work in most
environments - wherever t is safe for humans - and special fibers and
cables are used in high-radiation areas.
PC and APC Connectors
Q: Can you confirm whether there is a 1 mm gap in APC and UPC optical connectors?
A: PC, UPC and APC connectors are all physical contact connectors -
that’s what “PC” means. If you had a gap between the connectors when
making a connection you would have higher loss and reflectance except on
the APC.
Broken Fibers
Q: What could be the main reasons for this? A buried fibre cable has
broken cores, such that different cores break at different distances
(e.g. core 1 and 2 break at 6 km, core 5 and 9 break at 28km, etc) Why
would a core break at a point where other cores are not even showing a
loss?
A: A likely cause is exceeding the pulling tension or bend radius of
the cable during installation. How it affects fibers could be due to
the alignment of fibers at different points or how the cable was
stressed during installation. Often fiber is pulled using pulleys too
small or over a small radius exiting a duct.
Questions On Restoration Repair;
Q: I have been in several debates about fiber restoration, and
whether a cable being repaired should have all the fibers spliced
through the damage or just the active ones. The people I have the debate
with typically use the line "we follow industry standards" I am
inquiring about where I may find this issue referenced? I have many of
your books (if not all) but it would help me save time if you could tell
me where this specific issue is addressed? For the record, I am for
splicing all cables through and making the cable whole, to reduce
troubleshooting, and the ability to utilize existing fiber to install
new customers or roll a customer to a different fiber if their assigned
fiber needs to be repaired.
A: Let’s address the standards issue first. OSP standards are almost
nonexistent.. When it comes to restoration itself, the goal should be
to restore service as quickly as possible- e.g. splice enough fibers for
current service - then complete the restoration to return the cable
plant to its condition before the damage was done. Considering the time
required to locate, have techs drive to the site, prepare the cable for
repair and then return the cable plant to a secure situation (aerial or
underground), it seems “penny wise and pound foolish” to not complete
the jonb by splicing all the fibers. Do those who argue otherwise think
saving a few minutes now justifies having to do another major project in
the future to restore the other fibers?
Past Questions
OTDR Measures Fiber Length
Q: What property (or defect) of SM G.652D could possibly lead to
span length (fiber length determined by OTDR) being shorter than cable
length? The cable length is 2.517km vs 2.508km fiber length.*
A: It is not uncommon for the OTDR measured fiber distance to differ
from the cable distance read from the cable jacket. OTDR measurements
have errors typically greater than the differences you gave. However
there is another likely difference. THe OTDR measures time of flight
(test pulse out and return) to the end of the cable and calculates the
length based on the index of refraction of the fiber. Most cables have a
fiber length about 1% longer than the cable length to prevent stress on
the fiber when the cable is pulled, so your results showing the fiber
length as being shorter indicated the particular fiber in the cable has
an index of refraction that is different from the value being used by
the OTDR. This is a parameter which can be set if you know the proper
value for the fibers used in the cable.
What is Long Haul?
Q: Do we have a characterisation for long haul plant in terms of
length? How long should a fibre plant be to be called long haul? How
long is a metro and a campus fibre? Apart from length, are there any
other features required for a fibre plant to be called "long haul"?
A: There is no standard definition for “long haul,” but most people probably use the following guidelines:
Long haul: >20km
Metro: 2-20km
Campus: <2km
Premises: <500m
Again, there are no standards for the term “long haul,” so while most
long haul today is high speed (>10Gb/s) and may include WDM, some
long haul systems for special applications like electrical utility grid
monitoring may go long distances but at very low bit rates.
What's The Light Path Link
Q: Generally, how much does the distance travelled by the light
pulse (one way) differ from the length of the fibre (as measured on the
drum) There are probably differences (how ever small) between the
path of the light pulse (as it ping-pongs inside the core) and the
length of the strand.
A: In singlemode fiber, the light path length is the fiber length.
In multimode fiber it depends on the type of fiber and the individual
modes. Cable is generally made with the fiber being about 1% longer than
the cable to prevent tension on the cable elongating it and stressing
the fiber.
Reducing Attenuation
Q: What is the best way of reducing fiber optic attenuation
A: In any cable plant, the loss comes from the loss of the optical
fiber and loss at joints (splices or mated connectors) plus any stress
losses caused by bad installation of the cable. For a give cable plant,
the options are lower loss fiber or lower loss at joints. If you need
lower loss, the fiber loss is a function of the attenuation coefficient
(dB/km) times the length (km)., e.g 0.4dB/km X 10 km = 4.0 dB. So if the
length is fixed, you can try to find lower loss fiber. The loss at
joints is a fucntion of the methods of joining. Splices have very low
loss - 0.1 dB or less on singlemode fiber. slightly more on multimode
fiber. Connections can have loss from 0.1 dB to more than 0.5 dB,
depending on the type of connector chosen. On SM fiber, if connecctors
are top quality fusion splice on connectors and are properly cleaned
loss can be under 0.2 dB. Some connectors like the MPO multifiber array
connector can have losses up to 0.75 dB or more. Replacing connectors
with fusion splices is also a way to lower loss at joints. Here is a
reference to loss budgets: https://foa.org/tech/lossbudg.htm
Safe handling of fiber optics;
Q: Is there a particular glove recommended for safe handling of
FO's? I appreciate dexterity in handling may be important, but glass
shards / splinters into the skin is a significant risk as well. There
are vague references to using gloves, but looking for the preferred /
recommended type of glove.
A: Gloves are hard to use when dealing with bare fiber but thin
surgical gloves work for some people. Regular gloves are too clumsy and
some cannot stop fiber penetration. When working with cable, especially
armored cable or large cables, work gloves are good protection. You can
also get kevlar gloves that resist cuts but are flexible and cooler.
They are often advertised as kitchen gloves to prevent knife cuts.

Q: How do you detect fault location of fiber optics in the field? How much time it takes to detect geo-location?
A: The simple answer is an OTDR but the physical location depends on
cable plant documentation and location data like GIS data. The time
depends on the availability of data and equipment. Minutes to days?
"Certified' Cables
Q: we will be using a large number of fiber cables . We have
specific testing and reporting requirements for the cables that are
shipped to us. Each end needs to be tested in accordance with
IEC-61300-3-35, IEC 61300-1:2022 with automated analysis microscopy.
Instead of purchasing the cables and getting them certified upon
receiving them, is there an option out there that allows you to purchase
Fiber Optic Cables that have already been certified according to the
above listed requirements and come with some sort of clear proof of
that?
A: The question is the matter of definition of “certified.”
Generally it means testing to a standard as you note. Any reputable
manufacturer of these cables will supply documentation with the cables
that includes loss testing and connector inspection reports. If
the cable manufacturer does not supply that documentation, I suggest
finding another supplier. At incoming, it may be desirable to do a
AQL sampling, but testing these cables is very specialized. Not many
contractors are equipped with the special test equipment needed.
Calibrating Multimode Optical Power Meters
Q: Should I be calibrating multimode optical power meters with an
LED source or a laser? I know that standards call for testing multimode
loss with LEDs not lasers.
A: The reason standards call for testing MM fiber with LEDs is the
coherence of lasers leads to modal noise in the fibers and unpredictable
variations in loss. But the wide spectral width of LEDs makes
calibration less accurate than when using lasers at the correct
wavelengths. Calibrate meters with lasers, test fibers with LEDs.
Color Codes On Higher Fiber Count Cables
Q: Why do buffer tubes 13-24 repeat the colors with a black stripe
(black will have a yellow stripe)? Why does it start with black
stripe vs starting with blue? And what happens when you get to black
tube color again do you skip it?
A: Color codes are an interesting topic. The basic color codes go
back to the beginnings of multi-pair phone cables. TIA added color codes
for premises cable jackets and connectors in TIA-598 to the 1-12 color
codes for fibers and buffer tubes. FOA covers that basic system in the
online Guide here: https://foa.org/tech/ColCodes.htm
The question about the second black fiber, fiber 20, is an interesting
one. Many cables use black with a yellow stripe but Corning uses a clear
buffer with a black stripe.
https://www.corning.com/catalog/coc/documents/application-engineering-notes/AEN029.pdf
It turns out that cable manufacturers don’t all do it the same way
for higher fiber counts. Most use the 1-12 colors for fibers and the
same for buffer tubes. 12 fibers per colored buffer tube is the
tradition, but there are 24 fibers in some tubes, so it’s 1-24 colors.
Ribbon cables are another story. With the older hard ribbon designs,
cable manufacturers often printed information on each ribbon. Those are
becoming obsolete and you can’t print on the new flexible ribbons the
same way, so I’ve seen schemes to print dots and dashes on the fibers in
the ribbons!
So what we have is a standard, but standards are voluntary, so not everybody follows them!
Repairing Fiber Optic Connector Ferrules
Q: Can you take an existing fiber optic number connector and polish
the end if the end is to dirty or damaged that it cannot be cleaned via
dry or wet methods?
A: Yes, using special polishing techniques. We have a page on that in the FOA Guide: Fiber Optic Connector Repair
Grounding Armored Jumper Cables
Q: Do you need to bond/ground FTTH drop "jumpers" that ise an armored cable?
A: Yes, just like any other cable that has conductive elements. A
manufacturer of the cables Tinifiber seems to agree:
https://tinifiber.com/bonding-and-grounding-armored-fiber-cable/
I do not know of any fiber optic connectors that address this, unlike the RJ-45/modular 8-pin connectors for UTP copper.
Disoposal Of Fiber Optic Cables
Q: How does an organization dispose of unwanted fiber optic cables in an environmentally safe manner?
A: We recommend that users save some reels leftover from an installation
for possible use in restoration. If a cable break occurs, getting cable
quickly can be a problem. We also have a contact who says he can
recycle fiber optic cable:
Contact: Steve Maginnis, LD4Recycle/ CommuniCom Recycling, (Visit
website https://ld4recycle.com), sm@LD4Recycle.com, 803.371.5436
Otherwise, it is basically landfill.
Finding Buried Fiber Optic Cables Q: We have a client that needs their private fiber
located. We have been on site and confirmed the lines were
installed with no tracer wire or conductive conduit/sheathing.
Want to know if you had any suggestions on how to locate or if there was
specialized equipment that I am aware of. A: Interesting question on an important topic. The answer is a
qualified maybe. Ground penetrating radar (GPR) can sometimes spor fiber
optic cable, maybe more easily if it is in duct or conduit. It requires
someone with a lot of experince in GPR. There are companies around the
US with this capability. Then there is a new proposal using the sensing
capability of fiber with above ground vibrators. Nothing commercial is
available here as far as I know.
https://www.winlab.rutgers.edu/~hansiiii/papers/OECC_2020_Liu.pdf
Fiber Optics For Alarm Systems
Q: Can you please help me with having information about if do you know
if someone did use fiber for complete fire alarm systems, sensor, smoke
detectors, panels etc.
A: FOA checked with my technical contact at the IBEW, Jim Simpson, for this topic. Here is his answer:
NFPA does indeed have requirements for fiber in fire alarm systems. Keep
in mind, the requirements may vary depending on which edition of NFPA
72 the jurisdiction has adopted. The info below is based on the 2022
NFPA 72.
Chapter 12 covers Circuits and Pathways
Section 27.4 covers Communications Methods
Section 27.7 covers Public Cable Plant
Updating FOA Courses And Reference Materials
Q: How often are FOA courses updated? And when they get updated, what happens to those who would have done a previous version?
A: The FOA certifications are updated as needed to stay current with
technology and applications. Udates are incremental and we do not
require current certification holders to retake courses or exams. Some
of our updates are almost humorous. For example, over the last 20 years
the definitions of “hybrid” and “composite” cables have flipped twice in
several international standards. At the last time, we changed all
references to these cable types in all our materials to note the
confusion it creates, then purged all questions from our exams that
covered this confusing topic.
Fiber Optic Color Codes Reference Chart
Q: Has anyone made a fiber optic pocket reference chart that has cable
color orders, frequencies, or other commonly used info on it? A: The FOA has a page on its Online Guide that covers color codes
(https://foa.org/tech/ColCodes.htm). It is the most popular page in the
FOA Guide! It works great with a smartphone.

Online Credentials For FOA Schools And Certified Instructors
FOA switched to online credentials 1-1/2 years ago. Now every active FOA
certified fiber optic and premises cabling tech has an online
credential they can use to prove their certification, print paper
certificates and share on social media. When they add another
certification or renew, their online credential is updated.
FOA has now expanded the online credentials to its network of FOA
Approved training organizations and FOA Certified Fiber Optic
Instructors (CFOS/I and CPCT/I.) Now FOA Approved training organizations
and FOA Certified Fiber Optic Instructors can now also share their
credentials online.
Those evaluating fiber optic or premises cabling training organizations
will be able to quickly determine the status of the training
organization they are considering by following the link to the
organizations online credential. Likewise the qualifications of the
instructor are also available on their online credential which lists all
their FOA certifications.
The Types of Work Done By Fiber Techs And How It Affects Training
What is a fiber optic technician? What kinds of work
do they do? Those topics were the center of FOA discussions with the US
Department of Labor Bureau of Labor Statistics that led to the new job
category of "Telecommunications Technician" on the BLS
website. The focus of this job category is primarily the
installation and operation of the fiber optic cable plant, but one
should not forget the cable plant must be designed also as part of a
more extensive communications network.
In our discussion with the BLS analysts, we pointed out the various
stages of a fiber optic communications network project and how techs
with various knowledge and skill sets are needed and involved in every
step. Here is how FOA defines these stages of a project and the skills
of the techs. This is not unique to FOA; it's what has been traditional
at telecom companies forever.
Planning and Design: Once needs for a communications network is
established, project managers will be responsible for all the details of
the project while experienced fiber techs trained and experienced in
fiber optic network design (CFOS/D) will design the cable plant itself. (FOA Guide - Design)
Construction: Aerial cable plants may require installing new poles or
doing make-ready on existing poles and messengers. Underground
construction requires trenching and installation of ducts. In many cases
the actual construction is done by general construction workers, as the
construction work in many cases is not unique to fiber optics. Heavy
machinery is required for much of the construction work and training is
focused on safety as well as operating the machinery. (FOA Guide - Construction)
Fiber Optic Cable Installers: Once the route is prepared, the fiber
optic cable can be installed. Aerial cable installation depends on the
type of cable. Regular OSP cable, figure 8 cable and ADSS cable requires
special hardware and installation techniques so the techs must
understand the process appropriate for each cable. (FOA Guide - Installation)
Splicers: Since the beginning, fiber techs have been called
"splicers"
because that was the original job unique to fiber optics. Construction
and cable installation was not very different from earlier copper
cables, but splicing was very different. Even today, fiber techs are
often called splicers and splicing is a core skill for any fiber tech
whether they are joining cables or terminating them. (FOA Guide - Splicing)
Testers: After the fiber optic cable is installed and spliced,
it must be tested. Testing goes together with splicing since every
splice will be tested, often as soon as it is made so if it needs
redoing, it should be done before the splice closure is sealed. (FOA Guide - Testing)
Network Operators: Once the cable plant is built and the communications
equipment installed, it needs techs who know how to operate the comms
but may only know how to connect new gear or change connections on
current gear. These techs should also know how to troubleshoot systems
in an outage and either do the restoration themselves or call a tech who
can. (FOA Guide - Operation)
These categories merely define the stages of installation of a fiber
optic project. Of course there are subsets of these categories and most
fiber techs are expected to have skills and jobs that cross into
multiple groups, as FOA has defined in the KSAs (knowledge, skills and abilities) for a CFOT.
What an individual worker does differs according to their job. An
independent fiber contractor may cover every job except
operation and a FTTH subscriber installation tech may only understand
installing cables, testing and connecting equipment within the scope of
FTTH systems. A construction company may handle the trenching and even
pole setting as well as parts of the traditional fiber work.
The FOA defined its role early on to focus on educating and
certifying techs in the fiber specific skills: cable installation,
splicing, testing and restoration. FOA would like to see more schools
get into the construction phase, especially for newer techniques like
microtrenching and blowing cable, but these require large outdoor areas
for training and large investments in equipment. Most techs who learn
these processes now do it with OJT - on-the-job-training - and hopefully get OSHA
training for safety.
FOA School News
FOA's roster of approved schools is growing as more organizations
recognize our expertise in workforce development and our comprehensive
support for getting new schools started. FOA has over 25 years
experience and nearly 100,000 certified fiber techs (with ~130,000
certifications). As a non-profit organization founded by the industry
specifically to develop a competent workforce, FOA provides the
consultation, curriculum and contacts to get schools started as a free
service to new schools.
Need A Fiber Optic Course Onsite? Invite an FOA School To Come To You
FOA often gets inquiries from an organization that
has personnel that needs training in fiber optics. Recent inquiries have
included contractors, a manufacturer of high-reliability products using
fiber optics and a cable manufacturer. In many cases, where there are
several people needing training, FOA can recommend a FOA Approved School
and Certified Instructor who will come to their location to teach a
class. The advantage is of course the savings in travel costs if
the class comes to you, but it also offers the opportunity to customize
the course to fit your needs, even use your equipment or work on your
components, so the training is more relevant to those taking the class.
Contact FOA to discuss the idea of a custom, on-site class to see if it will better meet your needs.

New Fiber U Course: Fiber Characterization
FOA has added a new course at Fiber U on Fiber Characterization. Fiber
characterization is the process for testing long fiber cable plants for
its ability for carrying high speed communications. With so many
networks now operating at 100, 200, 400 or even 800 Gb/s, fiber
characterization is important, especially on older fiber optic cable
plants.The free Fiber U Fiber Characterization course is available in two forms, as a standalone Fiber U fiber Characterization Course with its own Fiber U Certificate of Completion and as a separate Lesson in the Fiber U Fiber Optic Testing course. This course is recommended for those studying for the FOA CFOS/FC Fiber Characterization certification.
Fiber U MiniCourses: Got An Hour Or Less?
Learn Something New About Fiber Optics.
FOA
has introduced a new type of Fiber U
course, the MiniCourse, a free online course you
could take in a short time, perhaps as you ate lunch
at your desk or took a coffee break. The
topics of these courses should explain what they are
about, and these are all very important topics to
fiber optic techs.
New Fiber U MiniCourse - Fiber Optic Jargon
There is a new MiniCourse at Fiber U - Fiber Optic Jargon.
Jargon is the most important thing you need to learn when you learn
about a new technology. This short Fiber U MiniCourse is intended to
introduce you to fiber optic jargon and make learning about fiber much
easier. It's aimed at novices but is a good refresher for even
experienced techs. Fiber Optics In Communications
The courses have two components, video lectures and
readings, that are complementary. As usual there is
a self-test to allow you to check your
comprehension. As with other Fiber U courses if you
desire, you can take a short test for a Fiber U
Certificate of Completion that costs
only $10. All these free courses and many more
are available at Fiber U.
What Fiber Techs
Don't Know -
What We Learn From
FOA Certification Tests
As
FOA moves more testing over to our digital online
testing system at ClassMarker, we have access to
more data about our testing, including what
questions and topics on the tests are answered
incorrectly most often. Having this data gives us an
opportunity to evaluate the questions and how they
are stated, but more importantly it allow us to help
our instructors teach the subjects and us to change
our curriculum and online courses to emphasize these
particular topics. These are some of the topics that
we have noticed are answered incorrectly more often
in FOA and Fiber U tests.
Most of the questions missed are on testing.
1. OTDRs - particularly what information is in the
OTDR trace.
2. The difference between dB and dBm
3. Loss budgets - both the concepts and doing the
math
4. Insertion loss testing - single-ended or double
ended for testing patchcords or cable plants, how to
set 0dB references
5. Units of measure - fiber is measured in microns,
wavelengths in nanometers, etc.
At FOA, we're working to add Fiber
U MiniCourses on these topics and working with
our schools to emphasize these topics in their
classes.
If you are going to be taking a FOA certification
course or test in the near future, these topics
should be on your final exam study list.
What We Learn From Hands On Labs
We learn about students performance in hands-on labs
from the feedback of our instructors and our own
experiences too. One big problem is the use of hand
tools. Growing up today, you learn how to use
keyboards, mouses and touch screens, but decades
ago, you also learned how to use basic hand tools.
This is big enough of a problem that we're
considering adding some video lessons on basic hand
tools to prepare students for cable prep,
termination and splicing that require the use of
hand tools.
FOA offers free online self-study programs at Fiber U.
Many users are preparing for FOA certification
programs - taking courses at our schools or using
the Direct Certification program. Some of our
schools are requiring Fiber U programs as
prerequisites for their classroom courses so they
can spend more time on hands-on activities.

Cross Reference To FOA Tech Materials
FOA has so much technical reference material, we created a cross reference guide to the textbooks,
Online Guide and Fiber U courses, all the FOA technical information.
Besides the textbooks, online Guide and Fiber U, each section of the
Guide also includes links to the 100+ FOA videos available.
To help those new to fiber optic workforce development, FOA has created a web page we call "Fiber Optic Workforce Development."
In this page, we share what we have learned about the fiber optic
workforce, who they are and how they learn their trade. We discuss what
defines a fiber optic tech and how they should be certified.
Just like they say in the product ads, it's new and improved!
It has been 5 years since we have updated the FOA Reference Guide To Fiber Optics,
so it is certainly time for an update. The latest version is different
enough we call it a new edition. Many of the updates are for new
technologies which are reshaping the fiber optic industry like coherent
transmission, BI fibers, etc. We've also added a section on the fiber
optic workforce which has much relevance because this book is used to
train those entering the workforce.
We've also worked on making the book more readable, adding formatting that eases reading and a new comprehensive index.
Inflation was an issue, but the price only goes up $2 to $29.95 for the paperback and $12.95 for the Kindle version.
The new edition of the FOA Reference Guide To Fiber Optics is available from Amazon and booksellers worldwide.

Best Seller: Fiber Broadband (Paperback and Kindle)
In less than half a century,
fiber optics has revolutionized communications and to a large extent,
society in general. Broadband, what many today call high speed Internet
access, has become a necessity for everyone, not a luxury. The
technology that makes broadband possible is fiber optics, connecting the
continents, cities, and just about everybody. Even fiber to the home
(FTTH) brings broadband to hundreds of millions worldwide.
How did we get from an era when communications was making a telephone
call or sending a telegram to today’s world where every piece of
information – and misinformation – is available at the click of a mouse
or touch on a screen? How did we get from a time when a phone was
connected on copper wires to being able to connect practically anywhere
on a handheld device with more computing power than was available to
scientists and engineers only decades ago?
How does broadband work? Without fiber optics it would not work.
This book is not the typical FOA technical textbook - it is written for
anyone who wants to understand fiber broadband or fiber optics or the
Internet. It's also aimed at STEM teachers who want to include
communications technology in their classes. This book will try to
explain not only how fiber broadband works, but how
it was developed. It is intended to be an introduction to
communications technology
appropriate for a communications course at almost any level (junior
high, high school or
college,) for managers involved with broadband projects, or for anyone
who just wonders how all this stuff works.
Paperback ($12.95) and Kindle ($9.95) versions available from Amazon or most booksellers. Kindle version is in color!

Safety
On Safety
New Fiber U Course: Fiber
Optic Safety
Safety
must be the first concern of everyone involved in a fiber optic
project, including those planning, designing, managing or supervising
and of course those doing the installation.
FOA is often asked about safety for fiber optics. Some
inquiries ask where it's covered in the FOA Online Guide or textbooks or
if we have a course on safety at Fiber U. Almost all Fiber
U Courses have lessons covering safety, because
safety is important in every aspect of a fiber optic project.
This
new Fiber U course will focus on safety alone. There are two lessons in this course,
fiber optic construction and fiber optic installation. The dividing
line between the two courses is the installation of the fiber optic
cables. Construction leads up to and/or is completed when the cables are
installed. Installation begins when the fiber tech installs the cable,
then completes the splicing, termination testing and documentation. The
overlap between the two is the installation of the cables where both
construction personnel and fiber optic techs are involved.
Here is the new Fiber U "Fiber Optic Safety" self-study program. Take the course and get your certificate of completion.
The FOA is concerned about safety! FOA
considers safety an integral part of all our
programs, curriculum materials and technical
materials. We start all our textbooks and their
online versions with a section on safety in the
first chapter, like this: Before
we get started - Safety First!
The FOA is a, international non-profit
educational association chartered to promote
professionalism in fiber optics through education,
certification and standards.
Founded in 1995 by a dozen prominent fiber optics
trainers and leaders from education,industry and governmentas a professional society for fiber
optics and a source of independent certification,
the FOA has grown to now being involved in numerous
activities to educate the world about fiber optics
and certify the workers who design, build and
operate the world's fiber optic networks.
