The fiber optic A/B switch with loopback is an all optical, fiber optic, latching style A/B switch (maintains the connection even when power is removed) that includes additional optical switching mechanisms to automatically loopback the unselected port. For example, if position A is selected, the A port will be connected to the C port, while any signals received on the B port will be looped back out port B. Likewise, if position B is selected, the B port will be connected to the C port, while any signals received on the A port will be looped back out port A. This is especially useful in failover applications, as this added functionality allows the "unused" circuit to be continuously tested to insure that it is operating correctly and available for use if needed.
