초록
An optical communication apparatus using a sub-carrier multiple access includes a laser diode for generating an optical signal with a central frequency, a temperature controller installed at a subscriber side for controlling a temperature of laser diode placed at a transmitting terminal, an optical coupler for coupling the optical signal outputted from the laser diode to an optical fiber and an optical receiver for receiving the optical signal outputted from the optical coupler. The central frequency of the optical signal outputted from the laser diode is changed in response to the change of the temperature controlled by the temperature controller.
