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 .
13.7 OPTICAL SPECTRUM ANALYZER APPLICATIONS The widespread
implementation of WDM systems calls for making optical spectrum analyses to
characterize the spectral behavior of various telecommunication network
The display shows measurement parameters such as spectral FWHM , mean -
wavelength position , and peak - power density . A gaussian or lorentzian curve
fit may also be displayed . ( Courtesy of Hewlett - Packard Co. ) the peak
