This Media Converter is 10/100/1000Mbps fast Ethernet converter. The converter mediates between a 10/100/1000Base-TX segment and a 1000Base-FX segment. It is primarily designed for large, higher speed/bandwidth demanding work groups that require expansion of the Ethernet network. It can extend the conventional 10/100M Ethernet or 1000M Ethernet from 275 m up to 20 km via the Fiber-optical Line (depends on the device). It is high performance, cost effective and flexible solutions for a wide range of applications in the field of LAN campus network.
