Fiber Distributed Data Interface (3)

• FDDI-II is designed for networks that need to transport real-time video or traffic that cannot tolerate delays. Bandwidth is divided into up to 16 separate circuits that operate at from 6.144 Mbps each to a maximum 99.072 Mbps. Each of these channels can be subdivided further to produce a total of 96 64- Kbps circuits.

• FDDI-II is incompatible with existing FDDI design.

• CDDI - Copper Distributed Data Interface (officially named: Twisted-Pair Physical Medium Dependent standard)

  • media: TP-PMD UTP5 or STP
  • max inter-station distance : 100m
