Ethernet switches for rail vehicles

Ethernet switches

To meet the growing need for more capacity in train communications networks, Westermo has introduced a new generation of Ethernet train switches that provide robust networks to support numerous end devices and high data rates. Specifically designed for train applications, the wide range of interoperable Viper switches delivers reliable and versatile solutions for train networks, “enabling optimal configuration for every need,” according to the company.

Compared to the company’s previous train switches, the new models provide a range of 12 and 20 ports standard Ethernet, Gigabit Ethernet and PoE (Power over Ethernet) variants as well as additional routing functionality to enable the connection of subnets and improved overall network performance. The switches are also available with up to five gigabit ports to meet the need for connectivity of gigabit end devices, such as WLAN access points and network video recorders.

The switches have been designed to be compact and ultra-thin, enabling installation within the confined spaces of railcar panels. The M12 connectors are integrated into the housing to reduce size and further protect against vibration. With their robust design, sealed to IP67 and vibration resistant to military standards, the switches are suitable for situations where mechanical stress, moisture, condensation, dirt or continual vibrations could adversely affect the function of standard Ethernet switches.
