Rogers (King's College London) offers a lucid explanation of present-day optical fiber communications technology in terms that require no formal scientific or mathematical background in the reader. He presents the principles of operation clearly without resorting to any math or equations. Starting with the nature of information, the book provides a comprehensive overview about information measurement and signal representation, bandwidth need and availability, optical transmission along fibers, optical sources and detectors, and analog and digital optical communications systems design. The final two chapters describe current and future trends in fiber optic communications technology. Five appendixes provide mathematical details of some extent on certain relevant aspects in the areas of communications and optics. The appendixes are not necessary for a general understanding of the book. No problems are given. General readers; lower-division undergraduates; two-year technical program students. O.
