摘要： A method of monitoring fiber optic circuits. Included is manipulating a first switch between a first state, with first connection points optically linked along a first optical signal pathway and second connection points optically linked along a second optical signal pathway, and a second loopback state, with the first and second connection points of a first pair of connection locations in communication along a path along a portion of the first and second optical signal pathways. With the first switch in the first state, a third pair of connection locations are linked to the first optical pathway and the optical throughout observed. The third pair of connection locations are then linked to the second optical pathway and the optical throughout observed. These steps are repeated as long as the first and second optical pathways transmit the optical throughout normally.
