Description
SynOptics 5904 FDDI Fiber Host Module 920-245-A Nortel Centillion 6-Port For Parts
The SynOptics 5904 is a 6-port FDDI Fiber Host Module designed for installation in SynOptics/Nortel Centillion ATM switch chassis. It provides FDDI fiber connectivity at 125 Mb/s over 1300nm multimode fiber, with configurable network and port settings accessible via the labeled faceplate configuration matrix. This unit is being sold AS-IS for parts or repair — the plastic housing on one FDDI port is broken.

Applications
The SynOptics 5904 FDDI Fiber Host Module was designed for use in SynOptics and later Nortel Centillion ATM switching chassis, providing high-speed FDDI backbone connectivity in enterprise and campus networks. FDDI (Fiber Distributed Data Interface) was a widely deployed 100 Mb/s (125 Mb/s on the wire) dual-ring fiber token network standard developed in the mid-1980s and heavily used through the 1990s as a backbone technology in large LANs, data centers, and campus environments before Gigabit Ethernet became dominant. Modules like the 5904 allowed Centillion chassis to aggregate FDDI rings and interconnect legacy FDDI segments with ATM backbones — a common migration path in the mid-to-late 1990s enterprise networking world. Today, this unit is primarily of interest as a parts source, particularly for the Sumitomo Electric SDM3101-XF FDDI transceivers and other components visible on the board.
This SynOptics 5904 FDDI Fiber Host Module (920-245-A) is being sold AS-IS for parts or repair. The plastic housing on one FDDI port is broken, as shown clearly in the photos. The module has not been tested and is not guaranteed functional. It is a good source of parts, including the Sumitomo Electric SDM3101-XF FDDI transceivers.
