The FRM401 is a 4U, 19(23)" fiber media platform rack that features 12 cards capacity and supports a four channel (four in one) Ethernet copper to fiber converter card for 10/100Base-TX to 100Base-FX multimode fiber (up to 2 km), single mode fiber (up to 120 km) or utilizing WDM (up to 60 km). WDM (Wave Division Multiplexing) converts each input-output data stream into separate wavelengths of light and transmits/receives these channels through the same optical fiber. The FRM401-SNMP management option provides a serial console, Telnet or SNMP management to configure each channel on the line cards and monitor chassis power, fan and card status.

The FRM401-10/100 is a four channel Fast Ethernet 10/100Base-TX to 100Base-FX manageable media converter card, which gives you the options to choose from the most popular fiber cabling connectors, ST, SC, or FC. Both multi-mode and single mode converter cards are available as well as BiDi which allows bi-directional transmissions using only a single fiber cable.
