Abstract:
An optical communication apparatus having a light receiving element for receiving optical signals including an optical calling signal and an optical communication circuit which includes an amplifier circuit amplifying the photocurrent generated by said light receiving element, performs predetermined processing necessary for the optical communication, and outputs a communication terminating signal on the occasion of termination of the optical communication,wherein there is provided a first circuit which always supplies a bias voltage to said light receiving element, creates a non-connected state between said optical communication circuit and a first power source as a power source thereof if said communication terminating signal or a signal associated therewith is outputted, creates a connected state between said optical communication circuit and said first power source by making use of the photocurrent generated by said light receiving element the occasion of receipt of said optical calling signal by said light receiving element, and holds said connected state until said communication terminating signal or a signal associated therewith is outputted.
