FRM220-155MS 2R Transponder

FRM220-155MS TransponderEnd of Life

The FRM220-155MS is a fibre to fibre optical media converter and repeater that allows data rates up to 155Mbps. FRM220-155MS supports 2R regeneration, which consists of re-amplification and reshaping. This converter is compatible with fibre interfaces such as 100Mbps Fast Ethernet, 155Mbps STM1 and OC3. The FRM220-155MS works well with FRM220-CH20 chassis as slide-in card or with FRM220-CH01, one slot chassis as a stand-alone fibre converter. When the FRM220-155MS card is placed in the FRM220 rack with SNMP management, the management can view the converter card's status, type, version, fibre link status and alarms. The card can be configured to enable or disable the port, reset the port or enable/disable Auto Laser Shutdown.
