Abstract
There is disclosed an optical transmission system which employs a plurality of receiver-transmitter pairs. One of the plurality of pairs is selected to propagate optical signals under control of switching means. The optical signal as propagated is monitored and if a fault is detected in the signal, another redundant receiver-transmitter pair is automatically switched in. This pair is also monitored to determine whether or not the optical signal is valid and if not, the sequence continues until a valid signal is being propagated.
