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.

11.3.3 EDFA Power-Conversion Efficiency and Gain As is the case with any
amplifier, as the magnitude of the output signal from an EDFA increases, the
amplifier gain eventually starts to saturate. The reduction of gain in an EDFA
occurs when ...
First, the source is connected to the OSA without the EDFA inserted in the line in
order to measure the output level from the source without amplification. This
yields the bottom trace of the spectrum-versus-wavelength display shown in Fig.
