Classification: CPC H | IPC H

Claim 17:
18. The optical wavelength setting device of claim 17, further comprising:
an upstream wavelength analyzer configured to receive first reply light transmitted from a second optical communication device in response to reception of the first transmission light and a second reply light transmitted from a third optical communication device in response to reception of the second transmission light, and to recognize a first upstream wavelength corresponding to the received first reply light and a second upstream wavelength corresponding to the received second reply light,
wherein the controller is configured to generate a second control signal for allowing a first receiving port of the first multiplexer to pass light corresponding to the first upstream wavelength and allowing a second receiving port of the first multiplexer to pass light corresponding to the second upstream wavelength, and to output the generated second control signal to the first multiplexer,
wherein the first receiving port transmits a reply light of the first upstream wavelength to the first optical transceiver, and the second receiving port transmits a reply light of the second upstream wavelength to the second optical transceiver.
