 How Optical Fiber Works - MiniCourse


Fiber Optic MiniCourse - How Optical Fiber Works

Fiber U MiniCourses are courses on a specific topic that you can take in about an hour or less. They are based on questions people ask FOA all the time, so the topics are recommended by our readers.

Level: Basic

Intended For:
Anyone interested in how optical fiber works to transmit light and signals as pulses of light
Designers of fiber optic communications networks
Users of fiber optic communications networks
Contractors and techs who install, operate and maintain them.

Objectives: From this self-study program you should learn:
The types of optical fiber (step index and graded index multimode and singlemode)
How fiber uses total internal reflection to contain light in the core
How and why light travels in the core of each type of fiber

You will need a basic understanding of fiber optics or at least a familiarity with fiber optic technology.
For an quick, simple overview of fiber optics, you can use one of these three options: 1) the Fiber U self-study program Fiber Optics in Communications and How It Works, 2) the FOA YouTube Videos Fiber Optics and Communications and How To "Talk" Fiber Optics or 3) Lennie Lightwave's Guide To Fiber Optics  

For more comprehensive preparation, see the Fiber U Basic Fiber Optics self-study program or the printed FOA textbook FOA Reference Guide To Fiber Optics.

Fiber U Certificate of Completion
When you finish, you can take an online test on this course to qualify for a "Fiber U Certificate of Completion." The test cost for a Fiber U MiniCourse is $10US.

Optical fiber is comprised of a light-carrying core inside an other layer of material called the cladding which traps the light in the core using total internal reflection. Different types of fiber
(step index and graded index multimode and singlemode) have different structures in the core and transmit the light differently leading to different performance specifications that determine their applications.

In this Fiber U MiniCourse, we will explain how the different types of fiber work and transmit the modes (rays) of light differently.

For this lesson plan you will be instructed to watch the videos, read the references and take a quiz (Test Your Knowledge) to complete the course.

Lesson Plans
Watch the videos, read the section in the FOA Guide and take the quiz. For this course, we recommend watching the videos first and then reading the FOA Guide page on optical fiber. There is a short quiz you can use to check your comprehension. The Certificate of Completion test is based on those materials.
