FDDI stands for
Fiber Distributed Data Interface. It is a set of ANSI and ISO standards for transmitting data in a local area network (LAN) using optical fiber as the medium. FDDI operates at speeds of up to 100 Mbps and is primarily used for long-distance and high-speed network backbones. It uses a dual-ring architecture, providing a high level of fault tolerance and reliability, making it suitable for large-scale network implementations.
