FDDI interface
FDDI is a kind of high transmission rate in the current mature LAN technology. It has the characteristics of a punctual token protocol, supports a variety of topological structures, and the transmission medium is optical fiber. Fiber Distributed Data Interface (FDDI) is a set of protocols developed by the American National Standards Institute (ANSI) to send digital signals on optical cables. FDDI uses dual-ring tokens, and the transmission rate can reach 100Mbps. CCDI is a variant of FDDI. It uses twisted-pair copper cable as the transmission medium, and the data transmission rate is generally 100Mbps. FDDI-2 is an extended protocol of FDDI that supports voice, video and data transmission. It is another variant of FDDI, called FDDI full duplex technology (FFDT). It uses the same network structure as FDDI, but the transmission rate can reach 200Mbps Because the use of optical fiber as a transmission medium has many advantages such as large capacity, long transmission interval, strong anti-interference ability, etc., it is often used in metropolitan area network, campus environment backbone network, and multi-building network dispersion environment, so the FDDI interface communicates in the network backbone It is more common on the machine, with the widespread of Gigabit, some Gigabit AC machines began to use this interface.
