Backbone Repeater

  • Specifically intended to extend two Ethernet Train Backbone (ETB) links
  • 4 x Fast Ethernet ports (2 lines)
  • Equipped with fault relays
  • Independent power source for each line when the distance is higher than 100 meters
  • Compliant with EN 50155 standard

VDS Rail's Backbone Repeater is specifically intended to extend two Ethernet Train Backbone (ETB) links for another 100 meters. This facilitates the use of a single Ethernet Train Backbone Node for a group of vehicles where the total length of the ETB segment would exceed 100 meters.

Fast Ethernet and Gigabit Ethernet versions are available.

Highest reliability ensured:
  • Two protected independent Ethernet lines
  • Fault relays, triggerable by loss of power or ethernet physical error detection
  • The internal PSU can be powered by 2 separate power sources for added reliability
  • The device is fully compliant with EN 50155 standard
