EN 50155 Ethernet Powerline Bridge

The Viper-002-PL series consists of Ethernet extenders and bridges for propagating Ethernet traffic over existing cabling.
The series is based on power line communication (G.hn) and is capable of bridging high bandwidth Ethernet traffic over
2-wire cables, even when there are oxidized connectors.

By simply installing a Viper-002-PL product on each side of the coupler, a bridge connecting the Ethernet networks on each
side is created. The power line technology allows using existing cables, which leads to significant financial savings when
refurbishing trains. The fact that no configuration is needed further contributes to the ease of use.

The Viper-002-PL series has been thoroughly tested by certified labs to ensure its compliance with the standard for
electronic equipment used on rolling stock, the EN 50155. For several characteristics, Westermo exceeds the requirements
mandated by the standard, e.g. by providing 1.5 kVrms insulation on all ports.

Furthermore, the design is based on Westermo’s long experience within the rolling stock market, which brings benefits
such as vibration safe integrated connector threading, IP67 ingress protection with GORE-TEX® membrane to prevent
condensation water build-up and ultimately a high MTBF and long service life under the harshest conditions.

The Viper-002-PL series is built in Westermo’s Swedish factory which is renowned for its extremely high standard, as
confirmed by a multitude of quality audits by demanding international customers. The factory is organized according to
lean manufacturing principles and it is equipped with sophisticated state-of-the-art quality assurance equipment.

Meeting the requirements for rolling stock, makes the Viper-002-PL series also very well suited for deployment in other
applications with severe operating conditions and extreme environments.
