The core strength of FRM220-1000DS media converter is the ability to convert any signaling rate, from 155Mbps to 1.25Gbps, being an Universal Fiber Converter - ideal for any communication standard like: Fast and Giga Ethernet, STM-1 and STM-4, OC-1, OC-3, OC-12 and OC-24, FDDI or Fibre Channel. FRM220-1000DS adds management features via SNMP or local console port (telnet) compared to the older FIB1-1000DS model. For local console the model must be purchased with a separate casing that offers serial console port, like the FRM220-CH01M or the FRM220-CH02M. The FRM220-1000DS Universal Fiber Converter is the state of the art versatile optical fiber media converter for SFP slot to SFP slot conversion. 1000Base-SX/LX/LHX/ZX, WDM /CWDM optical modules , OC3 or OC12 or FibreChannel 1G optical SFP modules can be used. Same rate SFPs MUST be used in both slots. FRM220-1000DS can accomodate any type of miniGBIC (SFP) optical modules, either multimode or singlemode type, being a perfect choice for applications requiring change from multimode to singlemode fiber operation or to single strand WDM BiDi fiber needs. Unit is offering unparalleled flexibility and easy migration from short-haul to long haul fiber connections by simply changing the optical module interface. The unit can be used also as a repeater, to extend fiber optic communication, unit working as a 2R device (reshape and re-amplify). FRM220-1000DS converter cand be used as card into the larger 20 slot FRM220-CH20 or 8 slot FRM220-CH08 chassis.
