Redundant Ring Ethernet Extender
DDW-225
The Wolverine DDW-225 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 DDW-225 is powered by the WeOS operating system allowing complex networking functions to be easily
configured. For simple applications, no configuration is required making the unit ideal for rapid installation.
With its robust aluminium housing, the DDW-225 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. The Transient Block-
ing Unit (TBU) is acknowledged as the most effective form of protection against damaging noise spikes caused by lightning
or high voltage equipment.
Only industrial grade components are used which gives the DDW-225 an MTBF of 700,000 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-225 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
and rail trackside applications.
WeOS has been developed by Westermo to allow us to offer cross platform and future proof solutions. WeOS can
de liver 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-225s can be created using the FRNT protocol, or by using OSPF, the DDW-225 can form
part of an enterprise network. For more details on WeOS functionality, please see the WeOS datasheet.
