Ethernet Repeater

Backbone signal regenerator
Ethernet Repeater image

The Ethernet Repeater is a device able to regenerate the Ethernet frame data and the electrical parameters to overcome the 100m maximum Ethernet segment limit imposed by the standard. It provides two independents Ethernet lines protected with hardware bypasses to guarantee the physical link in case of power failure. It is completely transparent to all Ethernet protocols and offers full speed connectivity on both lines. The device is available as FE (100 Mbps) or as GbE (1 Gbps). The internal PSU can be powered by 2 separate power sources for added reliability. Moreover, the device is equipped with a fault relay, triggerable by loss of power or ethernet physical errors detection. Designed to operate in harsh environmental conditions typical of rolling-stock applications, the Ethernet Repeater is fully EN 50155 compliant and provides the highest level of reliability and robustness required by the railway industry.

Highlights

  • 2 FAST ETHERNET OR 2 GIGABIT ETHERNET LINES REPEATED
  • 2 HARDWARE BYPASSES FOR MAXIMUM RELIABILITY
  • INSULATED WIDE RANGE POWER SUPPLY
