Design and implementation of a fiber optic token-ring local area network

Abstract

This thesis describes the design and implementation of a fiber optic token-ring local area network (LAN) . This design features fiber optic channels between stations on the network without the use of a wiring concentrator. The initial LAN electrical signal operating at 4 Mbps was provided by a LAN adapter card based on the TMS380 chipset developed for twisted pair copper wire. Since the physical characteristics of fiber and wire vary, use of this adapter necessitated that the design be able to deceiver system Successful LAN communications over the fiber optic channels are described.
