This is a state-of-art review of optical Frequency Division Multiplexing (FDM) network technologies. Authored by a leading expert on the topic, this book provides complete coverage of this active and rapidly growing field — from optical devices to network architecture, design and operation. It is the first book to focus on wide area all-optical networks. Optical FDM networks are particularly attractive because they are highly flexible, expandable and have very broad bandwidth. This book provides a background to the history of lightwave technology for communications and presents a detailed comparison of Optical FDM network technologies and the Time Division Multiplexing (TDM) scheme, on which all current digital telecommunications networks are based. It explains how optical FDM networks are achieved, primarily by optical passive devices and optical amplifiers at optical nodes, and the consequent advantages of their being independent of bit rate, bit synchronization and transport schemes. The book presents a comprehensive overview of the architecture and various components and subsystems of the optical FDM network and concludes with practical chapters on optical FDM network design and management. This is an excellent study of a technology which is rapidly becoming more important to understand. It is clearly written and includes 60 illustrations and 30 equations. This is essential reading for all broadband telecommunication engineers, lightwave device engineers, gigabit network engineers and researchers and graduate students who need to keep up-to-date on developing optical technologies. Kiyoshi Nosu is Group Leader of the Coherent Lightwave Transmission Research Group, NTT Transmission Systems Laboratories, Japan. He received his Ph.D. in electronics engineering form the University of Tokyo, Japan. He is a member of the IEICE, the Japan Operation Research Society, the Japanese Society of Applied Physics, and was co-organizer of the ICC'93 workshop on Photonic Networks.
