Abstract

A fiber-optic local-area packet communications system, developed for an office system, is presented. The system consists of a 10-Mb/s token-ring backbone-network. Up to 64 fiber-optic CSMA/CD (carrier-sense multiple access with collision detection) subnetworks are interconnected with the token-ring backbone-network using a bridge over a total length of 128 km. The fiber-optic CSMA/CD subnetwork can support up to 1024 fiber-optic medium-attachment-units (FOMAUs) and a network diameter of 3 km using 33-port passive star couplers, FOMAUs compatible with ISO 8802/3 attachment-unit interface (AUI), and fiber-optic repeater units (FORUs). The implementation and characteristics of the fiber-optic equipment of the CSMA/CD subnetwork and the token-ring backbone-network are described.<>
