What is FDDI?
| Fiber Distributed Data Interface |
|
Fiber Distributed Data Interface is an ANSI standard network that transmits data at 100Mbps. The FDDI protocol provides network services at the Physical layer and at the Data link layer as do Ethernet and Token Ring and it uses a counter rotating ring topology. FDDI typically uses optical fiber, but it can use twisted pair copper for short runs; a version of FDDI called TP PMD (twisted pair, physical medium dependent) can use Category 5 UTP for short runs. (TP PMD is occasionally referred to as CDDI, but CDDI is actually a trademark of Crescendo Communications.) A fiber FDDI network can support up to 500 stations over 2 kilometers. |
