Wavelength Division Multiplexing is important in supporting the needs of thousands of end-users of communications systems. Wavelength Converters in Optical Networks deals comprehensively with the third-generation networks that use WDM and includes current reviews of the relevant literature. The main themes are enhanced throughout with the use of diagrams, tables and graphs, for the clear understanding of students. This book will ably assist those studying this area. The in-depth analysis and clear presentation style illuminate the subject and will be of use for researchers and practitioners alike. Contents 1.
