Abstract
A system and method for detecting breakage in an optical fiber is disclosed. The system includes an acoustic detector coupled to the optical fiber to be monitored for breakage which operates to generate an electrical output signal when the sound of an optical fiber break is detected. A signalling circuit measures the output of the acoustic detector and operates to generate a signal indicative of the output of the acoustic detector, and an indicator circuit is responsive to the output of the signalling circuit to provide an indication of breakage in the optical fiber. In one preferred embodiment, a control circuit is also provided which operates to interrupt light transmission through the optical fiber when breakage of the optical fiber is detected.
