The FRM220-1000TS Gigabit Ethernet is an extremely versatile optical fiber media converter for 1000Base-T copper to SFP slot. Any type of Gigabit rate 1000Base-SX/LX/LHX/ZX or WDM/CWDM SFP transceiver can be installed in the FRM220-1000TS. The converter can accommodate any type of miniGBIC (SFP) optical modules, either multimode, singlemode or single-strand type. Unit is offering unparalleled flexibility and easy migration from short-haul to long haul fiber connections by simply changing the optical module interface. The Gigabit copper interface has only 1000 Mbps speed but is able to handle special "Jumbo" packets of up to 9K size. Because the FRM220-1000TS converter is completely transparent to Ethernet packets, it is able to support any size frames, including undersized or jumbo packets (9K bytes). LED indicators signal the power status of the converter, UTP port speed, Link, and duplex status, FX port Link and duplex status. Another key feature of FRM220-1000TS Gigabit Ethernet converter is the ability to convert from standalone media converters to cards for FRM220 series chassis, in matter of minutes. In an always changing and growing networking environment, such a versatile feature allows network operators to switch to higher density and aggregation hubs without the need to purchase new fiber optic converters. This simple, but so reliable idea, makes the FRM220-1000TS Gigabit Ethernet media converter one of the best choices of media converters for data carriers and service providers.
