1. An optical power supply system, comprising:
a plurality of power sourcing equipments each outputting feed light;
a plurality of powered devices provided so as to correspond to the plurality of power sourcing equipments and each converting the feed light output from their corresponding power sourcing equipments into electric power;
a detector that detects an electric power amount required by a power supply target of the powered devices; and
a power supply controller that controls, based on the required electric power amount detected by the detector, output of the feed light from each of the power sourcing equipments, wherein the power supply controller controls the output of the feed light from each of the power sourcing equipments such that a total power supply amount from the power sourcing equipments to the powered devices satisfies the required electric power amount and also a net power supply efficiency is equal to or greater than a predetermined value.
