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.

Because intramodal dispersion depends on the wavelength, its effect on signal
distortion increases with the spectral width of the optical source. This spectral
width is the band of wavelengths over which the source emits light. It is normally ...
This effect cannot be easily mitigated and is a very serious impediment for links
operating at 10 Gb/s and higher (see Secs. 3.2.6 and 13.4.5). 4. Reflections from
