    Optical alarm unit

    The 2000 Optical Alarm Unit monitors the power loss of a pair of singlemode fibers in a communications cable. The unit contains an FC-PC connectorized 1550-nm laser transmitter and optical receiver. It provides continuous optical-loss monitoring over two singlemode optical fibers that are looped back at the end of the monitored span. The device is self-monitoring and will set off an alarm if the laser or power supply fails.
