FOA Basic Skills


Lesson: Basic Skills Lab For Remote Training, Do It Yourself

Level:
Novice

Objectives: From this lesson you should learn:
  • Where to purchase basic fiber optic tools and components
  • How optical fiber transmits signals with light
  • How to perform basic fiber optic installation processes: striping, cleaving, splicing, terminating fiber

Prerequisite
Before taking this course, you must first take the Basic Fiber Optics online course at Fiber U and get your Fiber U Certificate of Completion.

Introduction
This is a basic skills lab for fiber optic novices covering how fiber works, cable preparation, splicing, termination and testing. You will be directed to watch some videos, perform some hands-on exercises and work with some simulations.

The hands-on exercises are based on readily available components and tools. You can purchase the tools and components you need online inexpensively and do the exercises yourself and/or as part of an online class. The lesson will give detailed directions based on the tools and components listed below.

The Lesson Steps
  • Obtain tools from school or purchase online
  • Follow exercises below
  • If part of an online course, you will demo what you learned to your instructor on videoconference
  • You may be asked to return the finished lessons and tools to school
 
Acquiring Tools And Components
This lesson uses the basic fiber optic tools and components shown below. These tools and components are readily available online at reasonable prices. The total cost if purchased from Amazon or eBay should be under $100. If you are purchasing for yourself, the search terms for Amazon, eBay, etc. are given as well as approximate prices.
If you are part of a class with an FOA approved school, they may send you tools or advise you to purchase them yourself.

BSL Tools 


Tools (with online search terms if purchasing online)
  • Fiber stripper, 3 hole 3mm/900micron/250micron (fiber optic stripper 3 hole ~ $12-15)
  • Aramid fiber scissors (fiber optic Kevlar Scissors ~$5-10)
  • Fiber cleaver (fiber optic cleaver approx. $20-25)
  • Visual Fault Locator VFL (fiber optic visual fault locator - ~$20-25)
  • Alternative: in searching you may find kits of the 3 tools above plus other items you can use for other exercises for ~$40-50 which is OK
  • Black vinyl work mat, ~2X3, 0.5X0.8m (black vinyl upholstery fabric, 1 yd, ~$5-10)

cable

Components (with online search terms)
  • SM cable, 2ea (fiber optic patch cord SC to SC singlemode 3-5m length, ~$10-15ea)
  • Mechanical splices (fiber optic mechanical splice, qty 5 or 10, ~$10-15)
  • Splice type connectors (fiber optic quick connector singlemode, qty 10, ~$9-10)

Additional Equipment Required

  • Safety Glasses (hardware or drugstore, ~$5)
  • Cleaning supplies (alcohol and wipes)
  • Fiber disposal bin (Paper cup with lid, marked "Fiber Scraps")

Please Note: This is not the usual online course - it is intended to guide you as you learn some of the basic skills used in fiber optics. It involves using actual tools and components in a realistic manner. Some of the processes here can be hazardous, like working with sharp scraps of optical fiber and chemicals.

Always wear safety glasses when doing any of these exercises and dispose of all fiber scraps immediately and properly.

Do not look directly into the light from the visual fault locator - it's bright!



These guidelines are strictly the opinion of the FOA provided for educational purposes and the reader is expected to use them as a basis for learning. The FOA assumes no liability for the use of any of this material.

Familiarize yourself with these safety procedures and follow them all the time. Watch
FOA Lecture 2: Safety When Working With Fiber Optics  or read
Online FOA Guide: Fiber Optic Safety 

Do not work with fiber without safety glasses and a proper work area that is easy to clean up.


We recommend working on a black vinyl mat to make it easier to see the fiber (and any scraps).
It is best to work on tile or concrete floors, not carpet. If you drop fiber scraps into carpet they can be very hard to find or pick up with a vacuum cleaner.
Place clean paper over your work area to keep from harming the worktable surface.

Safety glasses must always be worn. Use them, keep them clean, and protect them from damage like any other tool. Always wear safety glasses because you will generate fiber scraps that may fly through the air and land anywhere. If scraps get into your eye, you will be making a visit to the local hospital emergency room.
Do not allow others to watch you work unless they wear safety glasses also. Fiber scraps can fly a long way!

The broken or cleaved ends of fibers are extremely sharp and can easily penetrate your skin! Be careful to not stick the broken ends into your fingers, since they invariably break off and are very hard to find and remove. Most times, you have to wait for them to infect and painfully work themselves out.

Avoid these accidents by exercising a little caution. Dispose of all scraps immediately and properly. Put them in a properly marked paper cup or other container for disposal. Do not drop them on the floor where they will stick in carpets or shoes and be carried elsewhere. Do not eat anywhere near the work area.
    
Clean up after your exercises carefully.

Safety Rules - Read before beginning any exercises (above)


1. How Fiber Optics Works
(hands-on, one exercise)
2. Basic fiber optic cable handling and preparation (watch 3 FOA YouTube videos)

3. Fiber optic splicing and termination (hands-on, 4 exercises) These exercises need to be completed in this order as each of them are dependent on the prior exercise.

4. Testing



When you complete all exercises, you can get a Fiber U Certificate of Completion.
If you have watched all the videos, used the loss simulator and successfully completed all the hands-on exercises required you may take this Fiber U Certificate of Completion exam.

If you are taking this course yourself, the
Fiber U Certificate of Completion exam cost $20. Go here to pay and take the exam.

If you are
taking this course with an instructor from an FOA Approved school, they will provide the link for you to take the exam.
