Abstract
An optical communication system includes a first optical device including a transmission optical switch and a controller coupled to the transmission optical switch, and a second optical device coupled to the first optical device via each of a first fiber and a second fiber. The transmission optical switch is configured to operate in one of a first mode associated with the first fiber and a second mode associated with the second fiber based on control signals generated by the controller. Moreover, the controller is configured to perform a non-revertive switching operation on the transmission optical switch based on the satisfaction or the non-satisfaction of a predetermined condition or a plurality of predetermined conditions.
