Westermo has enhanced its series of Ethernet line extenders with the release of a high-speed, compact device that is capable of meeting the increasing data transfer demands within industrial applications. The DDW-142 is the latest addition to the Wolverine range, which uses SHDSL technology to establish a high-speed connection between Ethernet networks using any existing copper cables. The product is a fully managed device with Layer 2 switch functionality that enables effective Ethernet networks to be created over distances of up to 15 km. Data rates of up to 30.4 Mbits/s are possible, making the device suitable for connecting complex networks that may include a large number of devices requiring high bandwidth. An integral 2-port 100 Mbit switch allows two Ethernet devices to be attached and a RS-232 port enables legacy devices to be easily incorporated into the IP network.
