Control signal systems for use in configuring an optical switch such that a communication signal transmittable from a first fiber end may be transmitted along a desired pathway between the first fiber end and a second fiber end are disclosed. The systems include transmitting a control signal, either on-path or, if the switch is mirror based, off-path with a communication signal pathway over which the communication signal is transmittable in the optical switch. The transmitted control signal is received by a control signal detector that is maintained in a known spatial relation relative to the desired pathway. A feedback signal relating to the spatial relationship between the communication signal pathway and the desired pathway is output by the detector. The feedback signal may be utilized in configuring the optical switch in order to make the communication signal pathway coincident with the desired pathway and thereby achieve transmission of the communication signal over the desired pathway.
A method for use in configuring an optical switch such that a communication signal transmittable from a first fiber end may be transmitted along a desired pathway between the first fiber end and a second fiber end, said method comprising:
A method for use in configuring a mirror based optical switch having a plurality of positionable mirrors such that a communication signal transmittable from a first fiber end may be transmitted along a desired pathway between the first fiber end and a second fiber end, said method comprising:
