Wolverine – Ethernet Line Extenders for the global hazardous area market

Easy-to-use, compact devices for mission critical applications in hazardous areas


Westermo is delighted to announce the release of a significant extension to its range of compact and ultra-reliable Ethernet line extenders. The Wolverine range has been enhanced with three new models designed to meet the needs of the global hazardous area market.

The Westermo Wolverine Ethernet extender range is now fully certificated by independent approvals bodies to ATEX/ IECEX by BASEEFA making the products perfect for use at the extreme edge of Ethernet networks where there may occasionally be an explosive atmosphere.

The Wolverine range uses SHDSL technology to establish a high-speed connection between Ethernet networks using any existing copper cables. This can enable considerable cost savings to be made when installing new systems where in the past the only option would have been fibre. It is capable of cold starting at -40°C and operating at a constant ambient temperature of 70°C without the need for air-holes in the case. In these locations the robust DIN rail mounting clip and compact size also makes installation simple and fast.

Reliability and resilience are critical in these remote locations as maintenance opportunities are limited and network failure often mission critical. Westermo provides industry leading MTBF figures exceeding 500,000 hrs to the MIL-HDBK-217F standard.

The Wolverine’s WeOS operating system provides an extensive suite of IP networking standards allowing resilient and flexible networks to be created. Developed to allow cross platform and future proof solutions, WeOS delivers a unique level of security and enables the Wolverine to form part of a point-to-point, multi-drop or resilient ring network. In the event of any link or hardware failure, Westermo’s unique FRNT technology is able to re-configure a large network.

The Wolverine is transparent for multicast addressing, allows VPN (Virtual Private Network) pass-through for IPSec (Internet Protocol Security) and can be used with protocols like Modbus/TCP and PROFINET I/O. The Wolverine also features a Link Fault Forward (LFF) functionality whereby the Ethernet link status is sent over the SHDSL link between two units.

The Wolverine family is designed and manufactured in Westermo’s engineering facilities in Sweden. Our production facility is regularly visited by quality auditors from major global corporations ensuring the already high standards of manufacture are maintained and improved.
