Kurzbeschreibung
WDM is the basis of today's telecom and datacom transport networks and next-generation Internet transport. Approaching the topic from a strictly practical and application-oriented point of view, Wavelength Division Multiplexing: A Practical Engineering Guide thoroughly explores the main applications of both telecommunications and data communications. The authors provide the relevant background for state-of-the-art and next-gen systems and offer practical guidelines for system / link engineering. The book teaches engineers, students, and practitioners the major characteristics and their interrelation of state-of-the-art WDM systems, while looking forward with a discussion of the next generation of systems.
In this book, Optical Wavelength Division Multiplexing (WDM) is approached from a strictly practical and application-oriented point of view. Based on the characteristics and constraints of modern fiber-optic components, transport systems and fibers, the text provides relevant rules of thumb and practical hints for technology selection, WDM system and link dimensioning, and also for network-related aspects such as wavelength assignment and resilience mechanisms. Actual 10/40 Gb/s WDM systems are considered, and a preview of the upcoming 100 Gb/s systems and technologies for even higher bit rates is given as well.
Key features:
* Considers WDM from ULH backbone (big picture view) down to PON access (micro view).
* Includes all major telecom and datacom applications.
* Provides the relevant background for state-of-the-art and next-gen systems.
* Offers practical guidelines for system / link engineering.
