Wolverine DDW-226能够创建超长距离（最大15 km）的高效以太网网络，数据传输速率可高达15.3 Mbit/s。SHDSL技术使其能够重新利用许多类型的现有铜电缆，从而显著节约成本。根据电缆特性，可实现高达15 km（9.3 mi）的传输距离。WeOS 与集成RS-232端口的组合使得传统设备能够成为IP骨干网络的一部分。

DDW-226专为重工业应用而设计，配备坚固的铝合金外壳。宽范围的输入电源和I/O报警触点，使其在工业应用环境中便于安装，易于监控。瞬态阻断单元（TBU）被认为是防止由雷击或者高压设备导致的有害噪声尖峰的最有效方式。

只使用工业级部件，使得DDW-226的MTBF（平均无故障时间）达到70万小时，并且可确保长使用寿命。设备外壳无风扇或散热孔设计，可实现宽工作温度范围–40到+70°C（–40到+158°F）。DDW-226已通过威斯特摩内部和外部测试机构的检测，满足大多数EMC、隔离、振动和冲击标准，并达到重工业环境的最高水平。

威斯特摩开发的WeOS，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，例如可利用基于内部端口的防火墙功能来创建多端口DMZ。使用加密VPN可以远程安全访问网络。

可以使用威斯特摩FRNT协议或OSPF组建DDW-226环来实现弹性。DDW-226可用于企业网络。如需了解WeOS功能的更多信息，请参见WeOS参数表。

The Wolverine DDW-226 creates highly efficient Ethernet networks over extremely long distances (up to 15 km) with data transfer rates up to 15.3 Mbit/s. SHDSL technology enables it to reuse many types of existing copper cables, resulting in significant cost savings. Depending on cable characteristics, transmission distances of up to 15 km (9.3 mi) can be achieved. The combination of WeOS and integrated RS-232 ports enables legacy devices to be part of an IP backbone network.

The DDW-226 is designed for heavy industrial applications with a rugged aluminum housing. A wide range of input power supplies and I/O alarm contacts make it easy to install and monitor in industrial applications. Transient blocking units (TBU) are considered the most effective way to prevent harmful noise spikes caused by lightning strikes or high-voltage equipment.

Using only industrial-grade components, the DDW-226 has an MTBF (mean time to failure) of 700,000 hours and ensures a long service life. The housing is designed without fans or heat dissipation holes to enable a wide operating temperature range - 40 to +70°C (-40 to +158°F). The DDW-226 has been tested by Westmore's internal and external testing facilities to meet most EMC, isolation, vibration and shock standards and to the highest levels in heavy industrial environments.

WeOS, developed by Westmore, provides a cross-platform, future-proof solution. WeOS provides IP security features unique to this category, such as the creation of a multi-port DMZ using internal port-based firewall capabilities. Secure remote access to the network with an encrypted VPN.

DDW-226 rings can be built using the Westmore FRNT protocol or OSPF to achieve resiliency. The DDW-226 can be used in enterprise networks. For more information about WeOS capabilities, see the WeOS Parameter Table.
