Claim 9:
10. A method of setting a wavelength of an optical communication device, the method comprising:
recognizing a first downstream wavelength corresponding to first transmission light by analyzing the first transmission light, and recognizing a second downstream wavelength corresponding to second transmission light by analyzing the second transmission light;
generating a first control signal for allowing a first transmitting port to pass light corresponding to the first downstream wavelength and allowing a second transmitting port to pass light corresponding to the second downstream wavelength;
outputting the generated first control signal to a first multiplexer including the first transmitting port and the second transmitting port; and,
according to the first control signal, controlling the first transmitting port to correspond to the first downstream wavelength and the second transmitting port to correspond to the second downstream wavelength,
wherein the first transmitting port receives a transmission light of the first downstream wavelength from a first optical transceiver in the optical communication device, and the second transmitting port receives the second transmission light of the second downstream wavelength from a second optical transceiver in the optical communication device,
wherein the first transmission light includes first downstream wavelength information and the second transmission light includes second downstream wavelength information, and
wherein the recognizing of the first downstream wavelength and the second downstream wavelength comprises:
receiving first partial transmission light input by coupling a portion of the first transmission light and second partial transmission light input by coupling a portion of the second transmission light, and
recognizing the first downstream wavelength and the second downstream wavelength by analyzing at least a portion of the first downstream wavelength information included in the received first partial transmission light and at least a portion of the second downstream wavelength information included in the received second partial transmission light.
