Logical cut of an optical fiber due to fiber events

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;
• and
• 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 dampening the light on the output optical fiber to make the output optical fiber appear cut.

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;
• and
• 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.
