Train Ethernet Repeater

Backbone signal regenerator

Physical Train Backbones often reach the length of several hundred meters; accordingly with EN-61375 Ethernet Train Backbone Nodes are installed into consist in order to guarantee the proper communication train wise. Typically, physical distance between such devices is similar to the consists length, and, considering that everything has to work even if one of them is off-line, the distance between working ETBNs can double or more. The Train Ethernet Repeater is a device able to regenerate the Ethernet frame data and the electrical parameters to overcome the 100 m standard imposed maximum Ethernet segment limit and can be installed between two ETBN when installation parameters require it. Such Ethernet repeater provide double Ethernet line and hardware bypass to guarantee connections in case of fault. The device is available as FE (100 Mbps) or as GbE (1 Gbps). The Ethernet Repeater can be powered by 2 separate power lines for added reliability.  Designed to operate in harsh environmental conditions typical of rolling-stock applications, the Train 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
