Abstract

This chapter emphasizes fiber channel in detail. It describes the current main application area for fiber channel. Further, the chapter provides an insight of how fiber channels, in contrast with other network architectures, leverages the advantages of high-speed, high-reliability optical technology to provide high overall data communications performance. A fiber channel network is made up of one or more bidirectional point-to-point serial data channels, structured for high-performance capability. The basic data rate over the links is just over 1 Gbps, thus providing > 100 MBps data transmission bandwidth, with half, quarter, eighth, double, and quadruple-speed links defined along with 10 Gbps links under development. It is noted that the fiber channel protocol is configured to match the transmission and technological characteristics of single and multimode optical fibers, but the physical medium used for transmission can also be copper twisted pair or coaxial cable. Fiber channel is structured as a set of hierarchical functions. Interfaces among the levels are defined, but vendors are not just limited to specific interfaces among levels if multiple levels are implemented together.
