DDW-120 Ethernet extender

Using existing twisted pair cables to esta-blish a high-speed remote connection between two Ethernet networks is now possible with the DDW-120 Ethernet extender. This extender is an alternative to fibre optics or radio systems. The DDW-120 uses a transient blocking unit on each line interface to provide both over-current and over-voltage protection, allowing the line to handle indirect lightning strike transients, power induction and short circuit problems. Data rates from 192 Kbit/s to 5.7 Mbit/s can be achieved in both directions over distances up to 15km. The Link Fault Forward functionality forwards information about the Ethernet link status and sends it over the SHDSL link between two DDW-120 units, not affecting the bandwith. The units can be made operational without software configuration. Thanks to the total galvanic isolation and transient protection use in harsh environments is possible.
