Claim 0:
1. A method of modifying light on an optical fiber so that the optical fiber appears cut, the method comprising:
connecting a first optical fiber through an optical switch to an output optical fiber;
detecting a first fiber event on the first optical fiber;
in response to detecting the first fiber event, switching the optical switch from the first optical fiber to connect a second optical fiber to the output optical fiber;
in response to detecting the first fiber event, setting a first stability timer when the first fiber event has passed to ensure that the first optical fiber is stable for a predetermined period of time; and
in response to detecting a second fiber event on the second optical fiber before the first stability timer expires, modifying an optical signal on the output optical fiber so that the output optical fiber appears cut to a downstream transponder, wherein the modifying of the optical signal includes dampening a light signal on the output optical fiber so that the light signal is not detectable by a transponder, wherein the dampening of the light signal is controlled by a variable optical attenuator.
