2198 Westermo's DDW-120 Ethernet extender allows existing twisted pair cables to be used to establish a high-speed remote connection between two Ethernet networks. The company claims this is an easy-to-install alternative to optic-fibre or radio systems when linking remote Ethernet networks.

The device employs 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.

The DDW-120 uses twisted pair cables rather than expensive optical fibres or radio links. This plug-and-play unit covers many applications, offering data rates from 192Kbit/s to 5.7Mbit/s in both directions over distances of up to 15km (10 miles).

    Weather-related problems can render cost-cutting counter productive, according to CommScope’s Philip Sorrells. When severe weather conditions make headlines every winter, motorists and travellers seem willing to accept the impact on the trains and roads and yet take for granted that the communications networks will continue uninterrupted. They often appear far more upset that the information system does not give them an update on road conditions, train services or bus arrival times than they are about the a
