The FRM220-1000TS Giga Ethernet is an extremely versatile optical fiber media converter for 1000Base-T to 1000Base-SX/LX/LHX/ZX or WDM/CWDM that also provides NMS functions for Link-Loss-Forwarding, Remote-Monitoring-Status, and Loop-Back-Test. These optional features are especially useful when the standalone units are linked to one of our rack type units with SNMP or web management. FRM220-1000TS can accomodate any type of miniGBIC (SFP) optical modules, offering unparalleled flexibility and easy migration from short-haul to long haul fiber connections by simply changing the optical module interface. The Giga copper interface has only 1000 Mbps speed but is able to handle special "Jumbo" packets of up to 9K size.
