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).

    Greenowl’s voice-only congestion warning smartphone app alerts drivers to problems ahead and could be the way ahead for traffic information. If there is one point Matt Man, CEO of Canadian company Greenowl, wants to make clear from the start, it is that his company’s app is not a navigation system. He says: “Our system does not direct drivers to their destination because we mainly focus on commuters who know how to get to where they are going and only need information about any delays and incidents ahead of

    The challenge for surveillance systems is to ensure Power-over-Ethernet (PoE) switches provide high-power output and sufficient network bandwidth while remaining available and reliable. They must do so even when operating in extreme environments such as high temperatures, much noise and potentially high cybersecurity risks. To meet this challenge, Moxa says it launched its EDS-P506E-4PoE series of PoE switches. As well as being exceptionally rugged, each of the switch's four ports deliver up to 60W to powe
