: Covers the fabrication of fibers and cables, source to fiber power launching, and the basic principles of semiconductor lasers and LEDs. Detection and Receivers
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:
Every optical communication network relies on three primary elements to transmit information over long distances. 1. The Optical Transmitter
Because Gowar's text was a standard university curriculum book for decades, physical copies of the second edition are widely available at highly affordable prices on secondary marketplaces. : Covers the fabrication of fibers and cables,
Because it is a classic textbook, used physical copies are often available for a few dollars on platforms like ThriftBooks, AbeBooks, or eBay.
