Network Infastructure - FDDI

Fiber Distributed Data Interface (FDDI) is a standards-based solution that provides faster and more reliable data transfer on a local area network (LAN). Its sophisticated technology, which supports data transfer of 100 million bits per second (100 Mbps), was developed by the American National Standards Institute (ANSI). FDDI's unique capabilities have made it the technology of choice for high-speed networking applications.

Earlier LANs, such as Ethernet and Token Ring, can no longer meet all of today's growing network demands. These demands, such as increased throughput, greater network size, improved reliability, and superior fault tolerance, have surfaced because computing environments are becoming more powerful and data-intensive.

Here are some facts about FDDI:

• FDDI uses optical fiber as its transmission medium, providing security.
• Low signal loss, and high bandwidth data communication.
• FDDI can support simultaneous connection of over 500 nodes on a ring.
• With up to two kilometers between adjacent nodes, and up to 200 kilometers of total fiber length.
• FDDI uses a token passing protocol for access to the network.

The fiber optic cable installed in the site must conform to the American National Standard FDDI PHYSICAL LAYER MEDIUM DEPENDENT Standard, ISO.166-1990.

Scitex Whisper workstations should be connected through FDDI single attach concentrators .The Ethernet network is supported by Switching Hubs which connect all workstations with 10Base-T connectivity. It is impossible to install both an Ethernet LANC board and a FDDI board on the same Scitex workstation.
