The first comprehensive applied book in five years on this rapidly-changing area of telecommunications, here is the only resource capable of bringing you fully up to speed on the latest developments in fiber optic communication systems (FOCS). Designed to help you master the mathematics and statistics needed to create high-performance FOCS, Fiber Optic Communications offers current, in-depth coverage of optical amplifiers, optical detectors, wave-division multiplexing, optical heterodyne detection (OHD) systems, the pros and cons of OHD receivers versus direct detection receivers, and the design and performance of a proposed OHD system that features much greater detector sensitivity. Today's most detailed treatment of the present and future of FOCS, Fiber Optic Communications helps you to develop systems that will be able to fulfill ultra-high-speed communication requirements well into the 21st century.
