The Wolverine DDW-226 allows effective Ethernet networks to be created over long distances (up to 15 km) at data rates up to 15.3 Mbit/s. The SHDSL technology makes it possible to reuse many types of pre-existing copper cables which can lead to considerable financial savings. Dependent on cable characteristics, distances up to 15 km (9.3 mi) can be achieved. The combination of WeOS and the integrated RS-232 port allows legacy equipment to become part of an IP backbone network.

With its robust aluminium housing, the DDW-226 is designed for use in heavy duty industrial applications. The wide power range and I/O fault contact make it ideal for easy installation and monitoring in industrial applications.

Only industrial grade components are used which gives the DDW-226 an MTBF of 370,000 hours and ensures a long service life. A wide operating temperature range of –40 to +70 °C (–40 to +158 °F) can be achieved without the need for moving parts or cooling holes in the case. The DDW-226 has been tested both by Westermo and external test houses to meet many EMC, isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial environments.

WeOS has been developed by Westermo to allow us to offer cross platform and future proof solutions. WeOS can deliver unique IP security functionality for this class of product e.g.a multiport DMZ can be constructed by utilizing the internal port based firewall function.Remote secure access to a network can be provided using encrypted VPNs.

For resilience, a ring of DDW-226s can be created using the FRNT protocol, or by using OSPF, the DDW-226 can form part of an enterprise network. For more details on WeOS functionality, please see the WeOS datasheet.
