ETHERNET EXTENDERDDW-120 Ethernet extender allows existing twisted pair cable to be used to establish a high-speed remote connection between two Ethernet networks. With transfer rates up to 5.7 bits/s and an operating distance of up to 15 kilometers at lower data rates, this is an easy-to-install alternative to fiber optic and radio systems when linking remote Ethernet networks. The DDW-120 employs a transient blocking unit on each line interfaced to provide both over-current and over-voltage protection thus allowing the line to handle indirect lightning strike transients, power induction and short circuit protection.
