Westermo Wolverine DDW-142 SHDSL ethernet network extender

The Wolverine DDW-142 from Westermo allows effective ethernet networks to be created over long distances (up to 15 km) at data rates up to 15.3 Mbps on a single twisted pair cable by using SHDSL technology. By using two pairs bonded, this rate can be doubled up to 30.4 Mbps. The integral switch allows two ethernet devices to be attached and an RS232 port allows for legacy equipment to be incorporated into the IP network.

The DDW-142 is designed for use in tough environments and mission-critical railway, road or utility applications where device failure could result in significant costs. The rugged and very compact unit can operate in extreme temperatures (-40 to +70°C) and where EMC and vibration levels are high. Total galvanic isolation and transient protection of the electronics contribute to an MTBF of 437,000 hours, ensuring high operational reliability and a long service life.

To support engineers that are installing and maintaining ever-increasingly complex networks, the DDW-142 has been designed to be extremely easy to set up, requiring no configuration for simple point-to-point communications. For larger networks, a web interface is provided and a CLI allows even more complex configuration.

The Wolverine range is also supplied with a cable distance calculator. This uses data from real-world applications to enable installers to calculate the speed and achievable distances using different types of cable. Once installed, SHDSL diagnostics and management functions enable indication of line degradation allowing planned maintenance.
