X.21 Fibre Optic Modem with built in AC PSU

The FIB2 family are standalone fiber media converters available in a number of different models, with AC  power supplies built-in. The FIB2 family of converters may be applied in point-to-point applications or they may be linked to a centrally located FRM301 rack. The FIB2-X21 is a media converter for  X.21 high speed synchronous data transmission over optical fiber media. All media converters are available with either multi-mode or single-mode optical transceivers and with ST connectors.   When the FIB2-DATA is linked to the FRM301 with FIB1-DATA card, it allows network engineers to get greater functionality through advanced SNMP features. The network administrator can manage any converter module from anywhere on the network, detect any link loss and maintain each loop
