The FRM220-1000DS is a fibre to fibre optical media converter and repeater that allows data rates up to 1Gbps. FRM220-1000DS supports 2R regeneration, which consists of re-amplification and reshaping. This converter is compatible with fibre interfaces such as 100Mbps Fast Ethernet and 1000Mbps Gigabit Ethernet, STM-1, Fibre Channel 1 and OC3.  The FRM220-1000DS works as an FRM220 slide-in card, while the FRM220-1000DS plus FRM220-CH01 work as a stand-alone fibre converter. When the FRM220-1000DS card is placed in the FRM220-CH20 rack with SNMP management, the management can view the converter card's status, type, fibre link status and SFP DOM.


Fibre Transponder
FRM-1000DS as WDM Transponder



As a repeater in fibre applications, the signal is fully regenerated at the trunk. In the CWDM/DWDM application, the repeater acts as a fibre-to-fibre transponder and optical frequency converter between the client side equipment and the Optical Multiplexer/De-multiplexer. 




Management Features

This model should be managed via the console port in a FRM220-CH01M or in a chassis fitted with an FRM-220-NMC management card(see Chassis options below). When placed in a managed chassis, the card is configured and monitored through the chassis NMC (network management controller) via console, Telnet, Web HTTP or SNMP
