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.

Couplers with 64 inputs and outputs are possible, although, more commonly, the
size tends to be less than 10. One simple device is a power tap. Taps are
nonuniform 2x2 couplers which are used to extract a small portion of optical
power from ...
In specifying the performance of an optical coupler, one usually indicates the
percentage division of optical power between the output ports by means of the
splitting ratio or coupling ratio. Referring to Fig. 10-4, with Po being the input
This occurs because the carrier density in the gain region of the amplifier
depends on the optical input intensity. As the input signal level is increased,
excited carriers (electron-hole pairs) are depleted from the active region. When
there is a ...
