2.3100BASE-FX FIBER OPTIC NETWORK

Ports 1 and 2 of the 2M46-04R support the Cabletron Systems FE-100FX and FE-100F3 fiber optic interface modules. The device at the other end of the fiber optic segment must support the 100BASE-FX Fast Ethernet operations. The cabling between the devices must meet the test criteria for a 100BASE-FX link for the devices to operate at 100 Mbps. Refer to the Cabletron Systems Cabling Guide for details.

Multimode Mode Fiber Optic Cable

The test characteristics of a 100BASE-FX segment is covered in the Cabletron Systems Cabling Guide.

Single Mode Fiber Cable

The test characteristics of a single mode fiber optic link are similar to those for a multimode fiber optic 100BASE-FX link, with the following exceptions:

Cable type - 8.3/125 µM

Maximum Length - no more than 5 km from Data Terminal Equipment (DTE) to DTE in half duplex mode, or 20 km from DTE to DTE in full duplex mode.
