WDM Media Converter 10/100Mbps, Singlemode, 20km

The ME-3920-WDM20-SC (single fiber (WDM), singlemode) media converter transfers data over a single singlemode fiber at 100Mbps (at 1310nm and 1550nm) and connects to copper Ethernet at 10 or 100 Mbps while auto-sensing the correct speed. Maximum distance for this unit is 20km (12.4 miles). Distance on the Ethernet side is 100 meters (328 feet) using Cat-5 or better (unshielded or shielded twisted pair) copper cable. The fiber connections are SC and the copper Ethernet connection is RJ-45.

This media converter uses wave division multiplexing (WDM) which transmits and receives over one singlemode fiber optic strand (simplex fiber). It does this by using a different wavelength for each transmit and receive (1310nm and 1550nm). This is accomplished by using a matched pair of media converters, one of which transmits at 1310nm and receives at 1550nm, while the other transmits at 1550nm and receives at 1310nm.

Please note— This price is for two ME-3920-WDM20-SC media converters in a matched set. The price shown represents the price for both units together..
