2.3 100BASE-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.
