Compatibility With Other Ethernet Fiber Products

The 10BASE-FB Modules are compatible with the 3Com products outlined in Table 1-1.

Table 1-1. 10BASE-FB Module Compatibility

3Com Product	Part Number

10BASE-FB Star Coupler	9308S-FB

10BASE-FB Transceiver	5101T-FB

Fault-Tolerant 10BASE-FB Transceiver	5102T-FBFT

From the backplane interface, you can also connect the 10BASE-FB Modules to other Ethernet modules on the same network.

Caution: The 10BASE-FB Modules are not compatible with the ONline Ethernet 10BASE-FL Module (Model Number 5104M-FL1). The 4-port10BASE-FL Module faceplate is similar to the 10BASE-FB Modules, but the two modules cannot communicate.
