The DDW 100 Ethernet extender from westermot allows the use of existing twisted pair cables to establish a remote connection between two Ethernet networks. Using the high performance SHDSL (symmetric high bit-rate digital subscriber loop) Internet protocol, this is a cost-effective and easy-to-install alternative to fiber optic or radio systems when linking remote sites to a central industrial Ethernet network.
Due to its definition, a standard Ethernet network is limited to a 100m distance for point-to-point transmissions. In the case of higher distances a 10/100 Base TX Ethernet can no longer be used. To create a high-speed link between two distant Ethernet networks, optical fibers were previously necessary. Radio systems were a possible solution, but proved costly and difficult to implement.
The DDW 100 simplifies things by using twisted pair cables (existent or not) and the SHDSL high rate Internet telecommunications standard. This plug-and-play extender covers many applications offering data rates from 192kbit/s to 2.3Mbit/s in both directions over distances of up to 10km.
