Abstract
A system for locating breaks in fiber optic filaments employs light energy ulses which are controlled to be emitted at determinable times and directed along the light path of the fiber optic filaments under test. A pulse detector is positioned to receive any reflected pulse light energy from the fiber optic filaments and an indicator is responsive for indicating the elapsed time between the emission of the pulses and the reception of the reflected pulse light energy, preferably calibrated in terms of distance to establish the location of breaks in the fiber optics line.
