A system for monitoring health of a fiber optic cable in a telecommunications system includes an optical switch for receiving a plurality of light noise signals over the fiber optic cable and measuring the intensity of at least one of the plurality of light noise signals. The measured intensity data is transmitted to a monitoring system that then compares the measured intensity to a stored threshold intensity value. The system may also include a light signal generator for providing the plurality of light noise signals. The light signal generator may include a first amplifier for generating a light noise signal, a second amplifier for generating a corresponding amplified light noise signal, and an optical splitter for converting the amplified light noise signal into the plurality of light noise signals.
