Claim 10:
11. A system, comprising:
an optical switch having redundant first and second fiber optic inputs and an output coupled to a fiber optic transmission line;
first and second power taps on the first and second fiber optic inputs, respectively, to monitor power on the first and second fiber optic inputs;
a controller coupled to the first and second power taps to monitor for fiber events on the first and second fiber optic inputs;
circuitry coupled to the controller and to the fiber optic transmission line to logically cut the fiber optic transmission line using an attenuator to dampen light on the fiber optic transmission line, wherein the attenuator includes a variable optical attenuator coupled to the controller to dampen the light; and
first and second timers coupled to the controller, the first and second timers configured to track an amount of time since a fiber event has passed.
