Lesson 4: Fiber Optic Transmission Systems And Components

How do fiber optic communications links work?

 
Objectives: From this lesson you should learn:
How fiber optic data links and transmission systems work
What components are used in transceivers
Types of sources and detectors used in transceivers
Performance parameters of fiber optic transmission systems

Fiber optic transmission systems use datalinks that consists of a transmitter on one end of a fiber and a receiver on the other end. Most systems operate by transmitting in one direction on one fiber and in the reverse direction on another fiber for full duplex operation. A FTTH passive optical network (PON) is one of the few systems using bidirectional transmission over a single fiber because its network architecture is based around couplers already. Datalinks can be analog or digital, depending on the information being transmitted.

In this lesson you will learn how fiber optic systems transmit data.
