1. Why John Gowar’s "Optical Communication Systems" is a Classic
The book begins with the physics of light propagation through glass fibers. Do not search for a bootleg PDF
One of the defining characteristics of Gowar’s work is his "systems approach." Unlike texts that focus heavily on the quantum mechanics of light or strictly on the circuit design of receivers, Gowar integrates these elements into a holistic view. The book methodically builds the reader's knowledge, starting with the basic transmission medium—optical fibers—and culminating in the complex design considerations of complete communication networks.
One contemporary IEEE review noted that, given its exclusive focus on fiber optics, an even more precise title for the book would have been Optical Fiber Communication Systems . At the time of its publication, this was a rapidly expanding technology; the review highlighted that major telephone companies were already deploying fiber-optic links in major U.S. cities, with the first transatlantic fiber cable on the horizon.
