Optical fiber communications
The third edition of this popular text and reference book presents the fundamental principles for understanding and applying optical fiber technology to sophisticated modern telecommunication systems.
Optical-fiber-based telecommunication networks have become a major information-transmission-system, with high capacity links encircling the globe in both terrestrial and undersea installations. Numerous passive and active optical devices within these links perform complex transmission and networking functions in the optical domain, such as signal amplification, restoration, routing, and switching. Along with the need to understand the functions of these devices comes the necessity to measure both component and network performance, and to model and stimulate the complex behavior of reliable high-capacity networks.

routed networks use the actual wavelength of a signal as the intermediate or final
address. • Wavelength switching. Whereas wavelength-routed networks are
based on a rigid fiber infrastructure, wavelength-switched architectures allow ...
Wavelength-routed networks overcome these limitations through wavelength
reuse, wavelength conversion, and optical switching. The physical topology of a
wavelength-routed network consists of optical wavelength routers interconnected
