OPTICAL POWER FEED SYSTEM

A powered device 310A of a power-over-fiber system 1C includes a plurality of photoelectric conversion elements 311a, 311b, and 311c that convert feed light 112W into electric power. The powered device further includes a beam splitter 312 that receives the feed light, splits the feed light by wavelength into a plurality of feed light 112a, 112b, 112c in a plurality of wavelength bands, and outputs the plurality of feed light in the plurality of wavelength bands to the plurality of photoelectric conversion elements in a distributed manner. Each of the plurality of photoelectric conversion elements has a conversion wavelength range corresponding to a respective one of the plurality of feed light input and is configured to convert the respective one of the plurality of feed light input into electric power.
