FIB1-10-100W-SC20AF is a WDM(Wavelength Division Multiplexing) single strand fiber optic Fast Ethernet media converter with SNMP management support. Media converters can be ordered for both types A and B with the single SC type connector. FIB1-10-100W-SC20AF WDM converter(Tx:1310nm/Rx:1550nm) works on a SINGLE strand of singlemode fiber optic up to 20Km distance, with autonegotiation 10/100 and MDI/MDI-X features for the Fast Ethernet RJ45 UTP interface. The equipment support link-loss forwarding function (LLF), loopback test and remote monitoring. Used with their family of FRM301 fiber optic chassis they also support SNMP management and GUI applications. For proper operation, an A type WDM converter must always be matched with another WDM B type converter at the other end of the fiber optic cable.
