Abstract
A system for monitoring an optical cable includes a cable having monitor fibers solely for monitoring cable status. The monitor fibers may be fibers selected from optical fibers having a higher mechanical sensitivity to mechanical stresses than other fibers in the cable, which may attenuate earlier than the other fibers in the event of cable degradation. The monitor fibers may be in communication with a transmitter and receiver, for transmitting and receiving a monitor signal. The receiver may be in communication with an alarm, the alarm being operative to send an alert signal when an increased attenuation is detected from the monitor signal, the increased attenuation being indicative of the status of the optical cable.
