Claim 4:
5. The optical communication device of claim 1, further comprising:
an upstream wavelength analyzer configured to recognize a first upstream wavelength corresponding to first reply light and a second upstream wavelength corresponding to second reply light,
wherein the controller is configured to generate a second control signal for allowing a first receiving port to pass light corresponding to the first upstream wavelength and allowing a second receiving port to pass light corresponding to the second upstream wavelength, and output the generated second control signal to the first multiplexer, and
the first multiplexer includes the first receiving port and the second receiving port, and controls, according to the second control signal, the first receiving port to correspond to the first upstream wavelength and the second receiving port to correspond to the second upstream wavelength,
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.
