A complete, up-to-date review of fiber-optic communication systems theory and practice Fiber-optic communication systems technology continues to evolve rapidly. In the last five years alone, the bit rate of commercial point-to-point links has grown from 2.5 Gb/s to 40 Gb/s-and that figure is expected to more than double over the next two years! Such astonishing progress can be both inspiring and frustrating for professionals who need to stay abreast of important new developments in the field. Now Fiber-Optic Communication Systems, Second Edition makes that job a little easier. Based on its author's exhaustive review of the past five years of published research in the field, this Second Edition, like its popular predecessor, provides an in-depth look at the state of the art in fiber-optic communication systems. While engineering aspects are discussed, the emphasis is on a physical understanding of this complex technology, from its basic concepts to the latest innovations. Thoroughly updated and expanded, Fiber-Optic Communication Systems, Second Edition: * Includes 30% more information, including four new chapters focusing on the latest lightwave systems R&D * Covers fundamental aspects of lightwave systems as well as a wide range of practical applications * Functions as both a graduate-level text and a professional reference * Features extensive references and chapter-end problem sets.
