Abstract:
1. An optical communication system, comprising: a first optical device comprising 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, wherein 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, wherein the controller is configured: (e) to determine whether the predetermined condition is satisfied with respect to the second fiber; (f) if the predetermined condition is not satisfied with respect to the second fiber in step (e), to transmit a third control signal to the transmission optical switch that prompts the transmission optical switch to transition from the second mode to the first mode, and to return to step (b); and (g) if the predetermined condition is satisfied with respect to the second fiber in step (e), to return to step (e).
