Abstract
An optical communication device includes: a control signal generation unit that generates, on the basis of a communication log, a sleep cancellation signal including information about at least one time at which communication with a terminal device performing wireless communication with a power-receiving optical communication device is expected to be successful, the communication log including information about a result of communication at a time when sleep state cancellation is performed on the power-receiving optical communication device that is driven by electrical power obtained from an optical signal for power supply; and an optical communication unit that converts the generated sleep cancellation signal into an optical signal, and transmits the optical signal to the power-receiving optical communication device.
