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.

The spreading arises from the finite spectral emission width of an optical source.
This phenomenon is also known as group velocity dispersion (GVD), since the
dispersion is a result of the group velocity being a function of the wavelength.
5.2 LENSING SCHEMES FOR COUPLING IMPROVEMENT The optical power-
launching analysis given in Sec. 5.1 is based on centering a flat fiber end face
directly over the light source as close to it as possible. If the source- emitting area
These components range in complexity from simple passive optical splitters or
combiners to sophisticated tunable optical sources and wavelength filters. Before
we look at the optical networks that can be created with these devices, Chap.
