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).

    The continuing, favourable performance-versus-cost situation concerning detection and monitoring technologies is driving the proliferation of intelligence across road networks. The effective and safe management of intersections is a focus for network operators and systems manufacturers alike. The most complicated of road environments, and statistically among the least safe, intersections enjoy particular emphasis in longer-term work on cooperative infrastructure solutions.
