Abstract
An apparatus includes an optical power supply including: a power supply light source configured to generate power supply light; at least one optical input/output port; at least one photodetector; and a coupling module. The coupling module is configured to receive the power supply light from the power supply light source and output the power supply light through the optical input/output port, receive reflected light through the optical input/output port, and transmit the reflected light to the photodetector. The photodetector is configured to detect the reflected light and generate a signal representing a level of the reflected light. The optical power supply includes a controller that is configured to compare the level of the detected reflected light with a threshold value, and upon determining that the level of the detected reflected light is less than the threshold value, reduce or turn off the power supply light that is provided to the optical input/output port.
