1. An optical power supply system comprising: a power supply optical communication device that supplies power using an optical signal for power supply; and a power reception optical communication device that is driven by power obtained from the optical signal for power supply transmitted from the power supply optical communication device, wherein:
the power supply optical communication device includes one or more processors configured to:
transmit the optical signal for power supply to the power reception optical communication device, and
convert a continuous wave used for frequency conversion of a radio signal received by the power reception optical communication device into an optical signal and transmits the optical signal to the power reception optical communication device; and
the power reception optical communication device includes one or more processors configured to:
convert the optical signal transmitted from the power supply optical communication device into an electric signal of a continuous wave, and
perform frequency conversion on a radio signal transmitted from an external device by using the electric signal of the continuous wave.
