Introduction
The FOA created its Online Reference Guide to provide a more up-to-date and unbiased reference for those seeking information on cabling and fiber optic technology, components, applications and installation.  It’s success confirms the assumption that many users prefer the Internet for technical information.

Most information about fiber optics, including the information in the FOA Guide, is written for the technician who designs, installs or tests the network. But many times, if not most of the time, the success of a fiber optic project depends on those overseeing the project. This includes the manager of the organization for whom the network is being built, the planners behind the project, financial managers and particularly the people who supervise and evaluate the installation itself. After the project is done, there must be managers and supervisors who ensure the project runs smoothly, delivering the communications that keep users satisfied.

In this section on fiber optic projects, FOA ties together topics covered in many pages in the online FOA Guide and in chapters in some of our current textbooks, to provide a reference for those who manage the personnel we mention above. Here the focus is on the project from conception to completion; managing the people who design, install and operate it. We provide guidelines for all phases of the project, including enough technical details that managers can understand what technicians are doing and reporting about the project. We even link to the FOA "Jargon" page,  a pager about the “language of fiber optics,”  that helps everyone speak the same language when discussing fiber optic projects.

Don’t expect this section to provide all the answers; we don’t even know all the questions! Every fiber optic project like yours is different and unique. The communications needs, the geography of the cable plant, local laws, codes and regulations, and even the available technology which is ever changing, will all be unique to your project. Our hope is that we provide sufficient background that you can understand your own project well enough to manage it successfully.

Below we provide links for pages in the FOA Guide that will explain the details. Perhaps you don't need to study all of them at once. If you now what's here you can refer back to it when you need more in depth technical details. But we highly recommend you read this page and the page on Fiber Optic Project Management For Managers before you begin with any fiber project.


What Is Involved In A Fiber Optic Project?
A fiber optic project begins with a need for communications and ends with an installed fiber optic cable plant and an operating network that fills that communications need. Between those two points are a number of stages:
  • Concept
  • Selling the project to decision makers
  • Getting financing
  • Designing the project
  • Installing the project
  • Accepting the built network
  • Operating and maintaining the network
Each of these stages breaks down into many smaller projects with one thing in common - they require a thorough understanding of the project and careful management to ensure the end result is what is expected. This page is aimed to provide resources for the manager of the project and the people building the project to allow them to have a mutual understanding of what will be happening as the project moves from concept to completion.

Focus On The Cable Plant
The FOA's expertise in in fiber optics and we will focus on the fiber optic cable plant. What is a "fiber optic cable plant"? It's a term we use all the time in fiber optics to cover the installed fiber optics that can transmit your communications signals. It's permanently installed between the two points which you require communications between. It's what you connect your communications electronics to with patchcords on each end. The cable plant includes all the fiber optic cable between those two points. That cable may be buried underground or installed aerially on utility poles. It may even have segments that run under water - streams, rivers, lakes or oceans. Cables come in a maximum length of about 5km on a spool from the factory, so longer lengths will require splicing cables together. Splicing is also required if points along the route require connections (drops) as well as from end to end. At the ends, the cable plant will be terminated in connectors to allow making connections that can be changed as needed. Hardware is required for every splice and termination to protect the cable plant, splices, terminations and connected equipment, and these may require underground storage in manholes or above ground storage in pedestals, huts or buildings.

Designing and building a cable plant means carefully and completely defining the entire route of the cable plant, where every splice, drop, termination and piece of hardware is to be placed and what components will be used for every bit of the cable plant. It's a big job to design, but it must be done correctly to allow installation to be done according to the needs of the users.

Once finished, the cable plant must be fully documented so it can be operated, maintained and repaired if restoration becomes necessary.


What does it take to have a successful fiber optic project?
When asked this question, we often respond with 4 words: financing, commitment, expertise and patience. Here's what we mean:

Financing
The story goes that someone asked Neil Armstrong what he was thinking about while sitting on top of the rocket ready to launch Apollo 11 to the moon. “Every part was made by the lowest bidder,” was his reply.

Fiber optic projects are not necessarily expensive; in fact, fiber has been used so widely because it is the least expensive communications medium in virtually all projects. But like most other projects, it never pays to cut corners. Planning and running the project properly is what saves money, trying to cheapen the project. Not all jobs should go to the lowest bidder, unless they meet all the criteria for a qualified bidder. Likewise, one needs to ensure that when a project starts, there are funds available to complete the job properly, including some extra for unplanned changes or modifications.

Commitment
Just like having sufficient finances to compete the project, one needs a commitment to finish the job once it is started. Changes of management or changes in governments often lead to reconsidering a project in midstream. There is nothing wrong with making changes based on what learns as the project progresses, but arbitrary changes may jeopardize the project's completion or timetable, or even its usefulness. If the project is under the auspices of a government entity, changes in administration or management that causes changes in a project will invariably make it more expensive and may jeopardize the success of the entire project. Ideally, the personnel who propose, design and plan the network should see it to completion.

Expertise
Fiber requires expertise and experience. It's obvious the installers need to know what they are doing, but in reality, so must the managers who work for the organization that is contracting for the work. There are many instances of projects where the managers signed off o nthe project when it was incomplete or improperly installed. The only way to properly manage a project is to understand every aspect of it well enough to know if it is being done properly.

Anybody can become a consultant, but do they have relevant experience and have their projects been successful? Are they tied to vendors whose products they recommend?  Landscape contractors do not make good fiber installers, as one major company discovered, and contractors with a record of puncturing water mains while directional boring are likely to continue doing the same. The poor workmanship on aerial cables is particularly visible, so much so that FOA has been contacted by authorities asking if there were standards for this type of workmanship.

Planners, designers, contractors and installers should all be trained and certified as well as being experienced with good references. That holds doubly so for consultants. In many places, to be a consultant or cabling contractor means little other than registering as a business and advertising your services. In this section we'll discuss some of the problems we've seen with outside services, including consultants who took contracts, spent time on a project, then told the customer they could not help them with the project but kept the money. We have heard and seen contractors doing shoddy installations, ruining expensive fiber optic cable during pulling and leaving jobs half done but getting paid because the customer knew no better. One contractor gave the customer 144 copies of the same OTDR trace as proof they had completed the job. The manager must know better to prevent problems like this.

Patience
From concept to acceptance, a typical OSP fiber project can take 2-5 years and a premises project 1-2 years, depending on the size of the project, the time to properly design it, create project paperwork, get permits, buy components, hire contractors and properly install it.  Proper workmanship takes time and is not easily rushed. Saving time generally means cutting corners and that is often the cause of the problems encountered. Take your time, plan, design, select, install, test and document your network properly.

And by the way;...."future proofing" is a myth! Who would have known in 1990 how ubiquitous the Internet would be today? How reliant we could be on smartphones other mobile devices? How many workers would be working remotely or using videoconferencing for meetings? Technology moves too fast and is too disruptive for anyone to make reliable predictions. The IBMer who developed MRP - thei original company organizational software - used to tell everyone, "A forecast is wrong from the moment it is made."

Plan for the future, but assume you will upgrade, change directions, etc. driven by new tech and changes in the world around us.


About This Guide To Projects
We've broken this guide into smaller topics, roughly covering the progression of work from the conception to the completion of a fiber optic project. We further divide it into  categories Basic and Details/Comments, covering the basic information you need to know and more topics that go into more detail, depending on your needs and interests.

Introduction For Managers
Fiber Optic Network Management For Managers   
This overview will help you understand the overall role of the manager in a fiber optic project.
The jargon - the language of fiber optics Jargon Fiber optics has its own language as well as its own technology. This is a short dictionary of terms to help you understand and converse with others about the project.
Communications systems Fiber Optic Communications Networks  

LANs - Copper, Fiber and Wireless  
Practically every communications network operates on fiber optics, either totally or optionally. These links will familiarize you with how fiber is used in most common communications systems.

This FOA Guide section covers more

applications in depth. Refer to it for details on networks like fiber to the home, fiber for wireless  or optical LANs.

Planning the network and

Designing the network
Designing The Cable Plant (OSP, Premises)  

Designing Premises Cabling Systems (LAN, security, etc.)
Everybody focuses on the installation, but a successful installation requires a good design, and a good design takes a lot of planning and work. The manager needs to understand the process of design to ensure all the aspects of a design are done properly.
FOA also has a complete textbook on fiber optic network design.
Documentation And Paperwork - SOW to a contract, Project Paperwork   
You have heard it for years - the job isn't complete until the paperwork is done.
The Contractor Choosing a Contractor   This topic comes up in several sections of the  FOA Guide, including design and installation. That's because it is very important, and as a manager, it is important to participate in the process of choosing a contractor because you will have to work with them closely to build the cable plant.
Installing the network OSP Construction  

OSP Installation

Premises Cabling Installation  
These pages (and more in the FOA Guide) discuss the installation process in great depth, including the planning and management of the project. But there is one more page you should not miss - how to determine when the project is finished:
Accepting the finished system - deliverables   
Testing and troubleshooting
the fiber optic cable plant
Testing the installed cable plant   
Testing is one of the most important topics because it is what verifies the proper installation and operation of the cable plant at the end of construction, then allows troubleshooting when problems arise in operation or an outage requires restoration.

This section of the FOA Guide covers all aspects of fiber optic testing. FOA also has a complete textbook on fiber optic testing.

Operating and maintaining the network
Maintaining fiber optic networks  
Some people think a fiber optic network needs periodic maintenance but it doesn't. The network can be installed and operated for decades without maintenance, unless the configuration needs changing or restoration due to an outage is required. Electronics generally have monitoring and self-test functions to indicate when they fail or are near failing too.
