The SBFTF1010-130 Redundant Link Protector is 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. The 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.

When the primary path re-establishes its link the Redundant Link Protector will automatically switch back to the primary path. Optional functionality controlled via a dip switch allows the unit to move from the fault-tolerant mode to a 3-port switch mode.
