Westermo's DDW-220 Ethernet Extender


DDW-220 is an Ethernet extender enhanced with a built-in four port Ethernet switch which allows this one unit to be used to create entire Ethernet solutions. Existing twisted pair cables can be used to establish a high speed remote connection between two Ethernet networks. With transfer rates up to 5.7 Mbits/s and with an operating distance up to 10 kilometers at lower data rates, this is an easy-to-install alternative to fiber optic or radio systems when linking remote Ethernet networks. DDW-220 uses a transient blocking unit on each DSL line to provide both over-current and over-voltage protection on the line allowing it to handle indirect lightning strike transients, power induction and short circuits.
