FOA scheduled to be at FiberFest! - JUNE 13, 2012 -


Fiberfest is the one day conference/trade show run by the New England Fiberoptic Council. This year the event will be colocated with a FTTH Council meeting in Boston.
FOA will have a table at FiberFest manned by some of our local schools. President Jim Hayes will be participating in the FTTH Council programs.

Look for details here or on the NEFC website.

US Department of Labor Recognizes FOA In New "Occupational Outlook Handbook"

FOA is listed in the new US Department of Labor  "Occupational Outlook Handbook" in the section "How to Become a Line Installer or Repairer."

BLS recognizes FOA

This website lists all sorts of interesting information, including what these workers do in their jobs, how they get trained and certified (where the FOA is referenced) and something everybody is interested in - sections on "Pay" and "Job Outlook" - see the red arrow above.

Australia's NBN Shows Installation Schedule

We've covered Australia's National Broadband Network as it has been designed, but now they are posting information on the actual rollout by region and city. They've even created a NBN rollout map to show progress.

Australia NBN Rollout Map

You can see the enormous list of towns and their status here. Many towns have detailed maps of the installations that are interesting too.

Update: Google Fiber - Great for your telecom health!

Google Fiber Bar

April 1: Here's Google's new fiber product!  It's "Fiberlicious!"

Meanwhile, on a more serious vein, Google Hits a "Home Run" - Google has posted information on its installations in Kansas City for its gigabit FTTH project. They will use a "home run" architecture with every home connected by fiber directly to a Google fiber hut that is directly connected to an Internet backbone. This provides higher capacity for each home and symmetric speeds - upload and download speeds will be the same. You can read details here.

And IGI Group has just published a marketing report: "Google- A Telecom Threat?"

Permits For Fiber Optic Broadband Projects
WA  permits

In our design curriculum, one item we warn network designers about is getting the appropriate permits. The state of Washington, USA, contacted FOA about a online document they were creating for contractors and project managers in their state planning broadband fiber projects which would provide assistance in determining what environmental permits were needed and where to go get more information on the permits required. Even if you are not planning projects in Washington, this is a good document to read to help understand the permit processes.
Download the PDF here.

FOA Standards:

FOA has joined the American National Standards Institute (ANSI) to be able to keep up to date on more standards activities. ANSI is certainly a diverse organization. In March, when FOA joined ANSI, the list of new ANSI members included NASDAQ, Bonneville Power Administration and Broward (FL) County Sherriff Office Crime Lab!

FOA now offers standards for testing the installed fiber optic cable plant, patchcords and cable, optical power from transmitters or at receivers and OTDR testing. Look for the "1 PageStandard" web page and in the FOA Online Reference Guide.

Go to the FOA "1 Page Standards"

Free For FOA Members: NECA/FOA 301 Fiber Optic Installation Standard

Because of its importance to users, contractors and installers of fiber optic networks, The FOA and NECA have agreed to make the NECA/FOA 301 Fiber Optic Installation Standard available free to FOA members. It's specifically written to be used in contracts to define "installation in a neat and workmanlike manner."   FOA members can go here for instructions on how to download your free copy.

Two New Fiber U Online Self-Study Programs: Design and FTTx - coming soon: Testing

Fiber U www.fiberu.org
FOA has added two new free online self-study programs to our Fiber U web-based training site. The new programs cover topics that have been requested often: "Fiber Optic Network Design" and "FTTx." The Design course leads you through lessons on fiber optic network design and planning, then concludes with several online design exercises to test your understanding. The FTTx course has lesson plans covering what the "x" in FTTx means, network architectures, installation and testing, then concludes with a design exercise. Both use the FOA Online Guide or our textbooks and our YouTube videos as study materials. If you are interested in the FOA Specialist Certifications in Design (CFOS/D) or FTTx (CFOS/H), these are excellent study guides. See Fiber U for links to the new courses.

We are considering using these self-study courses as part of online instructor-led courses using Linked-In. We have a new LinkedIn group, "Fiber Optic Training" (see below) which will be used for this. Join now for these courses.

FOA Starts New LinkedIn Group On Fiber Optic Training
Linked In Training Group
FOA has started a new LinkedIn group called "Fiber Optic Training" dedicated to discussions on fiber optic training. Anyone can join our new Linked In fiber optic training group. We're experimenting on teaching instructor-led online courses on LinkedIn - watch for announcements on the FOA LinkedIn group and Fiber Optic Training Group. Take a look and join the group.

2012: The Year of The OTDR

Most of the technical and testing questions we get here at FOA involve misunderstanding of OTDR testing. A number of FOA master instructors have suggested we focus on OTDR training, both in our schools and online, to minimize the problems, so we have declared 2012 "The Year of The OTDR." Look for special articles, a new  "1pStandard" and other information that will make these instruments less enigmatic!

What A FOA Instructor Said: "So you've had discussions about making 2012 "The Year Of The OTDR" for training. I couldn't agree more. So many clients, contractors and sales people we meet have so little knowledge about OTDR that it's astounding. ... OTDRs are still subject to interpretation, user error and (in some cases) dead zones that can still effect the results. Everyone we teach is initially overwhelmed and looking for "E-Z OTDR" that is fully automated...!"

What An OTDR Can Tell You About Your Fiber
FOA Master Instructor Terry O'Malley has been creating some really useful data on OTDRs. He knows OTDRs - he created AT&Ts training program and taught it for years. Here is some data he created to show what traces look like for different fiber ends.

OTDR trace for cleaved fiber

Notice how big the reflectance peak is on the end of the fiber? Now look at this one:

OTDR trace for broken fiber

The OTDR can tell you a lot about the end of the fiber. The reflection on the end of the cable depends on the end of the fiber. If it’s broken and ragged, you will see practically no reflection, but a perfectly cleaved fiber will show a giant reflection peak. Note how the cleaved fiber has a high reflectance, reaching saturation on the OTDR trace while the broken trace shows only a small reflectance.
How is this useful? It helps locating breaks, which are usually broken fibers and determining if the end is a PC connector, which has high reflectance unless it's connected to another connector. But what happens with a APC connector? Those are designed to minimize reflectance so they show little if any reflectance peak. (Photos from FOA's OTDR FAQs.)

Three Good Practice Tools For OTDRs, All Free
You may already know that the FOA has a free OTDR Simulator you can download from our website (go here for directions) that allows you to practice using an OTDR on your PC, seeing the effects of changing setup parameters and analyzing dozens of real world traces. But here are two more tools that can be good for practice.

AFS OTDR Online Demo
AFS OTDR Simulator

AFS has an online interactive demo of their new OTDR that allows you to see how an OTDR makes measurements. You use the yellow buttons in the center of the OTDR to set the markers to make measurements. Very well done. Go to http://www.afsi.us/otdr/otdr_mode.php for the demo.

"Fiberizer" APP Reads, Analyzes OTDR Traces


Fiberizer is a iPhone/iPad APP that reads industry-standard ".sor" format files and allows trace analysis on your iPhone or iPad. An android version is in the works too. Read more about Fiberizer. And here are more directions on its use.

OTDR Tip Of The Month:

Last Month: What Does A PON Network Look Like On An OTDR?

Many of the technical questions we get here at the FOA deal with OTDRs and many are problems caused by untrained operators expecting the OTDR to do the trace interpretation for them. That is almost always a recipe for disaster! If you are going to use an OTDR, learn how to use it first. Start with the new Fiber U OTDR self study course, "Understanding OTDRs".  You can also download the Free FOA  OTDR Simulator to practice analyzing traces.

Free FOA iPad App Calculates Loss Budget

The FOA has just released its second APP for the iPad/iPhone/iPod Touch, a free "loss budget calculator," FOA LossCalc.

FOA LossCalc
FOA Loss Calc App Screen

FOA LossCalc estimates the optical loss of a fiber optic link. This will save time for the installer of a fiber optic link needing to know whether test results are reasonable and/or make a "pass/fail" determination. It can also help the designer of a link to determine if communications equipment will operate over this link.

By choosing the type of link (singlemode or multimode) and specifying the length of the fiber and numbers of connections and splices, it will calculate the end to end loss of the link. The app has default specifications for singlemode and multimode links or the user may create custom setups with specifications appropriate for any application.

Good Question! Tech Questions/Comments Worth Repeating

Tech Hint: Did You Know You Have A Fiber Optic Tester In Your Pocket?
Yes! The camera in your cell phone is sensitive to infrared light - lots more than your eye - and can detect light in an optical fiber or from a transmitter.  Chris Hillyer,
CFOT/CFOS/I, Master Instructor, Northern California Sound & Communication JATC sent us some photos showing how this works. See below or the video now on YouTube. Update: You should check out your old cell phones before you recycle them. We've found older models use sensors which are better at infrared than the newer ones which take better pictures. This is a good use for your old cell phones hiding in the drawer!

More on Loss Budgets (4/12)
Q: We manufacture cables for seismic industry which contains fiber optics. I have some questions after checking your loss budget document at http://www.thefoa.org/tech/lossbudg.htm.
a-If we want to establish the specs for max allowed attenuation for a cable containing 1 connector at each end (meaning the cable has 2 connectors); is it correct to calculate it this way:  2 x (0.75 db “TIA-568 max) + fiber loss along the length = our loss budget ?
b-What about the connectors of the optical power meter used for measuring (the ones we mate with each connector at end to transmit/receive the light)? Should I add their connector loss in the budget or I assume that the connector mate loss = max loss between one of both connectors (assuming the one at the cable has higher loss) for each end?
A: Let's start with question "b",  testing. For reference, I'm going to use the new FOA standard for testing the cable plant: FOA Standard FOA-1

I am assuming the connectors on the cable are compatible with the meter, e.g. some version of the SC/ST/FC family with 2.5 mm ferrules and you have some compatible launch and receive cables that have been tested and are known good.

When you do a reference calibration in the one cable reference method, you attach the launch cable to the source (leave it attached for the duration of the testing) and the other end to the meter input to do the "0 dB" calibration. Most meters have an adapter that screws on top of the actual detector of the meter so the end of the fiber faces the detector. This interface is not without some loss, but it is consistent in the coupling of the power from the fiber to the detector of the meter, so it is a constant in the measurement.

Now we know how much power is exiting the fiber of the launch cable. To test a cable, we attach the cable we want to test to the launch cable. That connection has loss that depends on the quality of the connectors on each cable and the alignment precision of the mating adapter for the connectors.

If we attached the other end of the cable we are testing to the meter now, we would measure the loss of the connection to the launch cable and the loss due to the attenuation of the fiber in the cable. Since the connector mated to the meter has the same interface as the reference cable when we calibrated  "0 dB" there is no loss added in this connection. We use this test for patchcords since it allows us to test each connector independently by reversing the cable and thus we can identify if we have one bad connector.

Completed cable assemblies are usually tested double ended, so on the opposite end from the launch, we attach a receive cable. The connection to the cable under test is added to the loss we measure and the connection to the meter is the same as for all other measurements so it is not included.

Thus the loss budget adds the connections on each end of the cable to the fiber loss since that is what is measured in this test.

Now we did this test with what we call a "1 cable reference" but there are options for 2 or three cable references. The standard linked above shows why you might use a 2 or 3 cable reference, it's a matter of the connectors on the cable and the meter and how they can be mated. What confuses people is what you are actually measuring with the 2 or 3 cable reference, since connections are included in the setting of the  "0 dB" reference. We have a web page that explains the math: http://www.thefoa.org/tech/ref/testing/5ways/lossmath.html

In our loss budget calculations, we always include the loss of the connectors on each end since most tests are done with a 1 cable reference. If you use a two cable reference, the loss is reduced by the amount of loss in the connection(s) during the setting of the 0 dB reference, plus the measurement uncertainty is increased due to the uncertainty of the loss included in the reference. We address the measurement uncertainty here: http://www.thefoa.org/tech/ref/testing/5ways/fiveways.html

Now question "a": The answer is "yes" with a caveat. That is how you calculate the loss budget. Most connectors do not have 0.75 dB loss! That number has been used in TIA and ISO/IEC standards for many years. It was created by manufacturers as a worst case value for them to use so that all types of connectors would meet the standards. In fact, the more typical values for loss are ~0.3 dB for adhesive polish connectors, ~0.5-0.75 dB for prepolished/splice connectors and ~0.75 dB or more for multifiber connectors.
So while 0.75 dB is in the standard and widely used, you may want to use a lower value more representative of the manufacturing process.

Burying Fiber Ducts Below Frost Line (3/12)
Should fiber ducts in northern regions be laid below frost line. Frost line in some areas of Canada is typically 8 feet.
A: Normally telecommunication conduit should be place below frost line when ever possible. Cost is always a factor, in most cases frost line does not exceed 36" (1 meter aprox). Northern Canada is an exception. Depending on the strength of the conduit/cables to resist the crushing force of ice frozen in place around cables (see manufacturer). Ice has been know separate conduits from itself, frost has crush conduits/cables. The following designs have been used:
1) Use schedule 80 conduit/ GIP conduit (threaded pipe).
2) Design each conduit section so that it will drain down hill.
3) Keep water out off handholes/manholes. This can be very difficult & costly.
4) Ensure that cables can maintain frost crushing (see manufacturer).

Companies like Bell /AT&T have been placing conduit below or at 3' to 5' in Canada.
Companies like CATV have been placing conduit below or at 2' to 4' in Canada.
In the US most conduits are placed 24" to 60" for communication.
Each situation will need to be reviewed on a case by case bases.

Municipal Fiber Network Advice (2/12)
I am charged with researching a municipal requirement to install fiber optic infrastructure in new development--this could either be for active development or dark fiber for future connection.  Any pointers as to where to look?  Have any communities done this well....  done this poorly....  have good examples of policy, legal code or standards?
A: Municipal networks are becoming very common. The best example I know is Santa Monica, CA Citynet http://www.smgov.net/departments/isd/smcitynet.aspx  and we've interviewed them on the project.
Santa Monica built a citywide network to combine connections to all the city offices, public safety offices, libraries, etc. plus added numerous CCTV surveillance cameras, smart traffic signals and muni WiFi. They installed lots of fiber - fiber is cheap but installation can be costly, so they built a big network with lots of dark fiber in the beginning. Then they leased fiber to the local CATV company, Verizon for FiOS fiber to the home, and connected up dozens of tech companies to high speed Internet access (Google, Yahoo and dozens of movie production houses are located in Santa Monica.)
The really good deal was it paid for itself. Federal money helped with the initial installation (DoTransportation, DoEducation, Homeland Security) and leased fiber keeps the income coming.
As  a big college town already involved with "Gig U" (http://www.gig-u.org/), you should contact the people at the University to see what they have planned that may be able to be combined with your work.
I suspect that every town has its own issues with policy, codes and standards. We've discussed some of the issues with other towns and one thing that comes up regularly is that at a minimum, the town should own the conduits even if the fiber is private. If a private contractor digs up the streets to bury cables they should be required to install many conduits for whenever another company wants to pull cable, the conduit is ready and no digging will be necessary. We also suggest talking to the local telephone and CATV companies. In the past, many have fought muni fiber but now many cooperate with the city and lease fiber from them.

Help On Termination 2/12
I'm working as an user and sometime I install connectors on fibers. Most of the time I work with ST connectors. Do you have a small guide how to prepare, and polish the fibers ? Is it possible to use ST single mode connector on Multimode fiber and viceversa ?
A: We have several links that help you:

YouTube Videos:http://www.youtube.com/playlist?list=PL21F27A040DFAA6E5&feature=plcp
Tutorial: http://www.thefoa.org/tech/ref/termination/Term/Term.htm
Step-By Step Virtual Hands-on Termination:  Epoxy/Polish, Anaerobic, Hot Melt
Singlemode fiber termination, Hands-on SM termination
Even more from the FOA Online Reference Guide: http://www.thefoa.org/tech/ref/contents.html#Components

Singlemode connectors have tighter tolerances and a slightly smaller hole in the ferrule. Generally speaking, you can use SM connectors on MM fiber, except when the fiber diameter is on the high side of tolerance but you should never use MM connectors on SM fiber as the fit will be sloppy and the resulting core offset causes high loss.

Removing Unused Cables 2/12
Can you point me in the direction of information on how to properly and safely remove 50 Micron Multi-mode Fibre Optic Cable from a data center?  My company would like to remove their old FOC when they upgrade to 10g cable fibre and were considering cutting the LC connectors off the cables to make it easier to pull through the rats nest of cables under the floor.  Is this a safe method?
A: There is not standard way to remove cables, as it will depend on the installation. Cables in underfloor (or overhead) trays tend to be enmeshed in other cables unless they are in separate ducts. Under any circumstances, the best way to remove them is to cut off connectors, locate the cables and cut into lengths that are easily removed (just make sure you are cutting the right cables - a installer doing this with some cables in Newark, NJ once cut the wrong cable and put Wall St. out of business for a day!). Once they are cut into short lengths, it should be easy to remove them.
After removal, the cable can be recycled for the plastic - connectors are trash. Or if they are long enough, I may know some schools who would like them for their hands-on labs!

Higher Loss At Long Wavelengths? 1/12
Q: I have a tech in the field that has installed a piece of single mode fiber approx. 650’ long. He is testing it with a source and meter. The fiber is passing the 1310 loss test but failing the 1550 test. What could be causing this? He has put new ends on the fiber already and is getting the same results.
A: This sounds like a classic problem of cable stress. Singlemode fiber is much more sensitive to bending stress losses at 1550nm than 1310nm. If there is a stressed area in the cable installation, it's easy to get >3dB loss from a tight bend or kink, even near the connectors. There should be no difference with the connectors themselves. Telcos test links at 1625nm for stress testing.
Followup: The tech went back to the job site with an OTDR and found there was a spike in the reading about 120’ from one end which is where there is a pull box up in the ceiling.

Fiber Cleaning
This is a topic we keep reminding everybody about, and here is why:

From a contrator in the Middle East: Here some samples of the connectors for SM fiber already installed in the system we were testing.
dirty connector   dirty connector
As you can see, the dirt is large compared to the size of the fiber (dark gray), and the core (not visible here) is only 9/125 of the overall diameter of the fiber! More on cleaningSee Product News below for links to vendors of fiber cleaning products.

See news about
Fiber Optic Cleaning Videos on YouTube by ITW Chemtronics below.

Measurement Uncertainty: Everyone testing fiber optics should understand that every measurement has some uncertainty - whether you are measuring loss, length, wavelength, power, etc. Knowing that uncertainty is very important to interpreting the measurement. It's worthwhile to read and understand the issue of measurement accuracy covered in this page of the FOA Online Fiber Optic Reference Guide.

What's ahead for multimode fiber communication systems?
By Gastón E. Tudury, Ph.D., and Al Brunsting, Ph.D., Panduit
With networks like Ethernet moving to 40 and 100 Gb/s, current multimode fiber has been forced to a parallel optics solution, not considered acceptable by some users like Google, due to the masses of fiber needed for data centers. Rather than go to a singlemode WDM solution, these two suggest we should look at redesigning MM fiber, cutting the NA for higher bandwidth and maybe tweaking the VCSELs too. Lightwave.

Benchmarking Fusion Splicing And Selecting Singlemode Fiber

We've been asked many times "How long does it take to splice a cable?" It's not a simple answer as it varies with the number of fibers in the cable and the work setup, including whether one or two techs are working at a job site. FOA Master Instructor Joe Botha of Triple Play in South Africa did his own analysis based on decades of experience both splicing cables and teaching others how to do it properly. This is one of the best analyses we have seen because Joe includes prep times as well as splicing times and differentiates between one tech and two techs working together. He adds some other tips on fusion splicing too. This should be mandatory reading for every tech and given to every student! Here is Joe's splicing analysis. 

Joe also has an excellent writeup on how to choose singlemode fiber that helps understanding the different types of G.6xx fiber. Read it here.

OTDR Software for Standardized Cable Plants

Noyes OTDR

Noyes has introduced new software for their OTDRs called Test Results Manager which helps viewing and analyzing OTDR traces. In addition, it can compare results to required performance for networks like 10G Ethernet and certify the fibers for those networks. There is an interesting note on standards here. The standards for the fiber optic cable plant required to support IEEE 802.3ae 10G Ethernet are specific to the network (see here for a list of most network fiber cable plant requirements) and if testing is being done to determine if the cable plant will support this network, testing must be done to the network standards not the generic cable plant standards to ensure proper operation. This is another common misconception of standards.  Read more on the Noyes TRM(r) software.

    JDSU Testing Book
    JDSU offers a free download of their Testing Guide from the Lightwave website. This is one great book which explains some basic fiber technology, but the real value is the last half which deals with OTDR testing. Not only does it give the usual info, but it covers important topics like measurement uncertainties and anomolies like ghosts and gainers.
    I was in the testing business for 20+ years at Fotec and think this book is one of the best fiber optic testing texts available. It's complete but comprehenisble! I used to believe that premises techs did not need OTDR training, but now OTDR manufacturers are pushing their use in premises networks. Unfortunately, the limitations of OTDRs in premises applications can cause extreme problems for those who are not aware of their limitations. So knowing hows OTDRs work is essential information to every tech.

    We get many questions from CFOTs, students at FOA-Approved schools and others contemplating getting into the fiber optic business regarding jobs in fiber optics - and how to find them - so we’ve created a new web page to share some information we've gathered about jobs in our industry. The information is designed to help you understand what jobs are available in fiber optics, how to find them and apply for them.
    While the overall economy is pretty bad - you've probably heard that there are 5 times as many people unemployed in the US as there are jobs available, telecom is a bright spot - broadband is a major focus of stimulus spending in the US and countries around the world are building fiber networks as fast as possible. Even wireless companies have to build fiber for their backhaul. Cities are installing fiber linked surveillance cameras and smart traffic lights. Fiber is the link making Smart Grid possible. Companies like Allied Fiber are building large private networks. Telecom is one of the fastest growing businesses worldwide.

    If you are looking for a job in fiber optics, here is the FOA's guide to jobs.

    The FOA has created a group on
    FOA on LinkedIn  expressly to help our CFOTs find employment and contracting opportunities. If you are a CFOT and are interested in participating, join us on FOA on LinkedIn. If you have job openings, let us post them on FOA on LinkedIn.

    Jobs Created As Part of Stimulus-Funded Projects
    The federal government is spending 7.2 billion dollars on the Broadband Technology Opportunities Program.  This money is working it's way into the economy and hopefully will provide jobs.  You can track recovery dollars and look for job opportunities on this website:
    www.recovery.gov  Go to "opportinities" link then "jobs".  You will see a section “find recovery jobs” – enter “fiber optic jobs California” or wherever you are and review what comes up.

    One of the projects funded by stimulus money is the 1100 mile network of
    Maine Fiber Company Inc. which has selected nextGen Telecom Services Group Inc. as the installation contractor. CFOTs: NextGen has a link on their website for applying for jobs

    FOA Certification Top Choice

    The FOA CFOT and CFOS programs continue to gain momentum in fiber optics. Over 36,000 CFOTs (December 2011) have been certified by over 250 schools. Since our founding in July, 1995, we have dedicated ourselves to promoting fiber optics and professionalism in fiber optics personnel, focusing on education and certification. We are continuing to add new schools and more CFOTs as users of fiber optics learn that a CFOT is the indication of a professional, well-trained fiber optic technician. Now with FTTH (fiber to the home) finally taking off, demand for CFOTs is rising and schools are responding by expanding programs rapidly.
    The FOA now has approved programs in place at 200+ organizations, welcoming new additions like the Joint Apprenticeship and Training Committee of the International Brotherhood of Electrical Workers, Corning Cable Systems and AFL (and their new acquisition "The Light Brigade" for their installation training programs) and NASA's Goldstone Tracking Station. The complete list of FOA-Approved schools is at http://www.thefoa.org/foa_aprv.htm.


    Understanding FOA Certifications
    To answer questions on FOA certifications, we have several web pages:
    Overview of FOA certifications
    Training Requirements - What Schools Are Teaching
    Reading these will help you understand what each FOA certification covers and how to prepare for them.

    Your Name, CFOT® - It pays to advertise!

    The FOA encourages CFOTs to use the logo on their business cards, letterhead, truck or van, etc. and provides logo files on this site for that purpose. But we are also asked about how to use the CFOT or CFOS certifications. Easy, you can refer to yourself as "Your Name, CFOT" or "Your Name, CFOS/T" for example.

    Feel free to use the logo and designations to promote your achievements and professionalism!

All current CFOTs have a ID Card with their certification data and we keep a database of current CFOTs to answer inquiries regarding your qualifications if needed.
