Fiber Distributed Data Interface - FDDIFiber distributed data interface (FDDI) is a computer network protocol that utilizes fiber optic or copper cable as the transmission medium to provide a token-passing, logical ring topology network operating at 100 Mbps. FDDI also provides for a mode of operation whereby two counter rotating rings are used to provide immediate fail-over and ring recover should a fiber cut occur. FDDI was commonly used as a backbone network to interconnect lower speed Ethernet and Token Ring networks within an enterprise. The American National Standards Institute standard X3T12 defines the protocol.
Fiber Distributed Data Interface (FDDI) System
This figure shows FDDI system that uses dual rings that transmit data in opposite directions. This diagram shows one dual attached station (DAS) and a dual attached concentrator (DAC). The DAS receives and forwards the token to the mainframe computer. The DAC receives and token and coordinates its distribution to multiple data devices that are connected to it.
