In this book, Optical Wavelength Division Multiplexing (WDM) isapproached from a strictly practical and application-oriented pointof view. Based on the characteristics and constraints of modernfiber-optic components, transport systems and fibers, thetext provides relevant rules of thumb and practical hints fortechnology selection, WDM system and link dimensioning, and alsofor network-related aspects such as wavelength assignment andresilience mechanisms. Actual 10/40 Gb/s WDM systems areconsidered, and a preview of the upcoming 100 Gb/ssystems and technologies for even higher bit rates is given aswell. Key features: * Considers WDM from ULH backbone (big picture view) down toPON access (micro view). * Includes all major telecom and datacom applicatio...
