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.

where Whz is the high - impedance amplifier noise characteristic given by either
Eq . ( 7 - 86 ) for FET designs or by Eq . ( 7 - 92 ) for the bipolar transistor case .
The thermal noise of the transimpedance amplifier is thus modeled as the sum of
The noise figure of the optical amplifier itself was thus 4 dB , compared with the
theoretical minimum of 3 dB with complete ... 5 SYSTEM APPLICATIONS In
