The Wolverine series of SHDSL Ethernet extenders can be used in point-to-point, daisy chain or ring applications. SHDSL
represents the best of several symmetric DSL technologies allowing transmission distances of up to 6.2 mi (10 km) with data rates of up to 5.7 Mbit/s. The technology we use makes the Wolverine series ideal for transmitting Ethernet over long distances on legacy copper cables. The units will auto-negotiate the transmission speed, but can also be forced to choose a slower (more reliable) or faster (less reliable) data rate. Total galvanic isolation and transient protection are standard for all interfaces. The line nterfaces are also equipped with extensive protection against current and voltage surges. The units are designed for extended temperature operation, have dual power inputs and can operate in extreme environmental conditions. The built-in 4 port Ethernet switch in the DDW-200 series makes it possible to create a simple Ethernet network with no additional network devices.
