威斯特摩以太网扩展器技术基于SHDSL，能够重新利用许多类型的原有铜电缆，从而在安装新系统时显著节约成本。Wolverine DDW-242能够创建超长距离（最大15 km（9.3 mi））的高效以太网网络，一根简单的双绞线电缆的数据传输速率可高达15.3 Mbit/s。通过“胶合”双绞线，该传输速率可翻倍到30.6 Mbit/s。集成交换机能够连接2个以太网设备，一个RS-232端口能够将一个遗留设备纳入到IP网络中。

  只使用工业级部件使得Wolverine 的MTBF（平均故障间隔时间）达到43.7万小时并且可确保长使用寿命。机箱内无活动零部件或冷却孔，可实现宽工作温度范围–40到+70°C（–40到+158°F）。Wolverine已经过威斯特摩和外部测试机构的检测，可满足大多数EMC、隔离、振动和冲击标准，达到适用于重工业环境和铁路轨旁应用的最高水平。

  WeOS由威斯特摩开发，使我们能够提供跨平台、面向未来的解决方案。WeOS可提供该类产品中独有的IP安全功能，例如可利用基于防火墙功能的内部端口或者Modbus网关支持来创建多端口DMZ。使用加密VPN可以远程安全访问网络。

Westmore Ethernet extender technology is based on SHDSL and enables the reuse of many types of legacy copper cables, resulting in significant cost savings when installing new systems. The Wolverine DDW-242 is capable of creating highly efficient Ethernet networks over extremely long distances (up to 15 km (9.3 mi)), with data transfer rates up to 15.3 Mbit/s on a simple twisted-pair cable. By "gluing" twisted pair, this transfer rate can be doubled to 30.6 Mbit/s. An integrated switch can connect two Ethernet devices, and an RS-232 port can incorporate a legacy device into an IP network.

Using only industrial-grade components enables Wolverine's MTBF (mean time between failures) to reach 437,000 hours and ensures a long service life. There are no moving parts or cooling holes in the chassis, allowing for a wide operating temperature range - 40 to +70°C (-40 to +158°F). Wolverine 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.

WeOS was developed by Westmore and enables us to provide cross-platform, future-proof solutions. WeOS provides IP security features unique to this category, such as the creation of a multi-port DMZ with firewall-based internal ports or Modbus gateway support. Secure remote access to the network with an encrypted VPN.
