ABSTRACT
This chapter explains the Fiber-Optic Network without wavelength division multiplexing (WDM). The fiber-optic networks are based on fiber channels organized into five levels FC-0, FC-1, FC-2, FC-3 and FC-4. Fibernet and solar net are based on passive star and Fibernet-II is based on active star topology. It is impractical and uneconomical to upgrade every time the bit rate handling capacity of synchronous optical network according to the requirement of increasing traffic demand; however, a cost-effective solution to this problem is implementation of WDM technology in backbone networks. The chapter discusses generation of networking in which the signal will be transmitted in an optical domain but multiplexing, switching, etc. will be performed in an electrical domain. In ring topology, the most popular networks such as fiber distributed data interface (FDDI) and its extension version FDDI-I are discussed in this chapter. The chapter describes Fasnet architecture with slot and Expressnet architecture with flow of packets. The basic FDDI medium access control protocol is fundamentally the same as IEEE 802.5.
