2.2100BASE-FX FIBER OPTIC NETWORK

The front panel ports of the module provide connections that support 100BASE-FX fiber optic cabling. The device at the other end of the fiber optic segment must meet 100BASE-FX Fast Ethernet network requirements for the devices to operate at 100 Mbps. IEEE 802.3u 100BASE-FX characteristics for Multimode Fiber is a segment length of 412 meters (switched port) in half duplex, 2 kilometers (switched port) in full duplex. This distance will be considerably shorter from a repeater port. Make sure to check your network diameter specifications. Refer to the Cabling Guide for details.
