The Wolverine series Ethernet extenders create cost-effective Ethernet networks with extremely long distances and data transfer rates of up to 15.3 Mbit/s. SHDSL technology enables the reuse of many types of legacy copper cables, which can lead to significant cost savings as there is no need to install expensive fiber optic cables. Depending on cable characteristics, transmission distances of up to 15 km (9.3 mi) can be achieved. The DDW-120 is configured using only a DIP switch, which ensures a quick installation.

The Wolverine DDW-120 is designed for heavy-duty industrial applications. The wide power range, comprehensive diagnostics and TBU transient protection make it ideal for installation and monitoring in industrial applications.

Using only industrial-grade components allows the DDW-120 to achieve an MTBF (mean time between failures) of 600,000 hours and ensures a long service life. No moving parts, wide operating temperature range -40 to +70°C (-40 to +158°F). The DDW-120 has been tested by Westmore and external testing organizations to meet most EMC, isolation, vibration and shock standards to the highest level for heavy industry environments and rail side applications. DDW-120 is transparent to multicast addressing and VLAN packets, allows VPN over IPsec and can use protocols such as MODBUS/TCP and Profinet IO. A simple plug-in diagnostic cable can be used to collect line diagnostic information, allowing the user to determine the quality of the line being used. The link fault forwarding function helps to send media fault indication information to the connected port to ensure that the DDW-120 is available in a resilient network architecture.
