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.
