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).

Since the early 1900s, taxes on petrol (gasoline) and diesel fuels have been used to finance the construction and maintenance of roadway infrastructure and, in some countries other government spending too. Now, a combination of improved fuel economy, the advent of hybrid and alternative fuelled vehicles and a reluctance in some countries (especially the US) to increase fuel taxes has led to a d
