Abstract
A power supply side optical communication apparatus supplies power to a power receiving side optical communication apparatus using an optical signal. A power storage unit stores the supplied power. A data control unit superimposes data control information related to transmission/reception of data transmitted/received by a data transmission/reception unit on the optical signal for power supply. A control information detection unit detects the data control information superimposed on the optical signal for power supply. A power supply control unit detects presence of transmission and reception of the data in an optical transmission/reception unit and an external transmission/reception unit on the basis of the data control information and data stored in a data storage unit, and supplies the power to the optical transmission/reception unit or the external transmission/reception unit according to the detected presence or absence of transmission and reception of the data.
