3Com 122-00704-000 Switching Division Circuit Board

3Com 122-00704-000 FDDI Switching Module is a two-port fiber-optic switching circuit board designed for 3Com LANplex backplanes, delivering dedicated FDDI switching capability via two fiber ports that connect to FDDI networks. This revision 04 module functions as a dual-port FDDI switching module and is typically cataloged as part of 3Com's Switching Division, intended to be installed in compatible chassis to manage fiber traffic between network segments. Common deployments include LANplex 2500 and 6000 series systems, where the 122-00704-000 provides the fiber-interface component required for high-speed ring-based fiber networks. Being an OEM 3Com component, it is a discrete circuit-board module rather than a standalone device, aligning with 3Com's legacy modular backplane networking approach.
