OPTICAL POWER SUPPLY SYSTEM

An optical fiber power supply system 1C comprises: a power supply device 110 which outputs power supply light 112; and a power receiving device 310 which converts the power supply light 112 from the power supply device 110 into power. The power converted by the power receiving device 310 is supplied to a wireless communication device 360. The optical fiber power supply system 1C further comprises: a communication monitoring unit 370 which acquires communication operation information regarding the operation status of wireless communication by the wireless communication device 360; and a power supply control unit 150 which controls the output of the power supply light 112 from the power supply device 110 on the basis of the communication operation information acquired by the communication monitoring unit 370.
