Claim 4:
5. A method of logically cutting an optical fiber, the method comprising:
detecting a first fiber event on a first input optical fiber coupled to an optical switch;
detecting a second fiber event on a second input optical fiber coupled to the optical switch;
in response to detecting the first fiber event, setting a first stability timer when the first fiber event has passed to determine that the first input optical fiber has been stable for a predetermined period of time;
in response to detecting the second fiber event, controlling light on an output optical fiber coupled to an output of the optical switch to logically cut the optical fiber, wherein the controlling of the light includes adjusting a variable optical attenuator to dampen the light on the output optical fiber to make the output optical fiber appear cut; and
in response to detecting that the predetermined period of time has passed, adjusting the variable optical attenuator to place the first optical fiber back in service.
