Abstract:

A fiber optic component testing apparatus includes first and second transceiver devices respectively placed on proximal and distal ends of a fiber optic component. The first transceiver device transmits a visible light signal from an optical transmitter into the proximal end for the fiber optic component to conduct to the distal end. An optical reflector of the second transceiver device reflects the light signal at the distal end back towards the proximal end. A sensor of the first transceiver device monitors the light signal reflected by the optical reflector to determine whether a power level of the reflected light signal is greater than a given threshold. The sensor activates an indicator light to flash for a technician to view (and activates an indicator speaker for the technician to hear) when the power level of the reflected light signal is greater than the given threshold.
