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.

A key reason for selecting a fixed frequency spacing , rather than a constant
wavelength spacing , is that when locking a laser to a particular operating mode it
is the frequency of the laser that is fixed . The ITU - T Recommendation G . 692 ...
The curves show the maximum power per channel as a function of the number of
wavelengths for three different channel spacings ( recall that a 125 - GHz
frequency spacing is equivalent to a 1 - nm wavelength spacing at 1550 nm ) , a
The OSA normally sweeps across a spectral band making measurements at
discretely spaced wavelength points . This spacing depends on the bandwidth -
resolution capability of the instrument , and is known as the trace - point spacing .
