Classification: CPC H | IPC H

Claim 16:
17. An optical wavelength setting device comprising:
a downstream wavelength analyzer configured to analyze first transmission light and second transmission light output from a first optical communication device and recognize a first downstream wavelength corresponding to the first transmission light and a second downstream wavelength corresponding to the second transmission light; and
a controller configured to generate a first control signal for allowing a first transmitting port of a first multiplexer to pass light corresponding to the first downstream wavelength and allowing a second transmitting port of the first multiplexer to pass light corresponding to the second downstream wavelength, and to output the generated first control signal to the first multiplexer,
wherein the first transmitting port receives a transmission light of the first downstream wavelength from a first optical transceiver in the first 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 first optical communication device, and
wherein the downstream wavelength analyzer is configured to:
receive 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
analyze the received first partial transmission light and the second partial transmission light and recognize the first downstream wavelength and the second downstream wavelength.
