At the genesis of every optical link is the transmitter. The role of the transmitter is to take an electrical signal (representing data, voice, or video) and convert it into an optical signal. Gowar’s text explores the two primary light sources used for this purpose:

Transmitting data requires converting electrical signals into precise pulses of light. Gowar covers two primary semiconductor sources:

At the destination, the optical signal must be converted back into an electrical signal. The text examines:
