10/100BaseTx fault tolerant redundant link protector


  • A 10/100 Ethernet fault-tolerant transceiver that significantly reduces network down time by adding a new level of redundancy to 10/100 Ethernet connections.
  • Redundant Transceiver has three ports: one for the critical (main) device, one for the default (primary) path to the critical device, and another (backup) for the backup path.
  • It is a smart device that will not send any signal on a path that is inactive.
  • If the primary path loses its link, then the transceiver will switch to the backup path in approximately 189 milliseconds.
