Abstract
The invention is an optical fiber detection system which includes a light source, a pair of optical couplers, an optical fiber loop and two photodetectors connected to the fiber loop. The optical couplers direct the light about the fiber loop such that one of the detectors detects the occurrence of disturbances in the fiber loop, and the other positively detects the occurrence of breaks.
