Abstract:
A node in a wavelength division multiplexing (WDM) system is provided, which includes: a colorless optical transmitter, a first arrayed waveguide grating, a first waveband filter configured to divide an input optical signal into M sub-signals of different wavebands and output to a first optical switch, and a first optical coupler/a first optical combiner. A transmit end of the colorless optical transmitter is coupled to an input end of the first waveband filter via the first arrayed waveguide grating. The first optical switch is configured to connect an output end of the first waveband filter to an input end of the first optical coupler/the first optical combiner according to a control signal. An output end of the first optical coupler/the first optical combiner is coupled to an optical transmission path.

Claim (Index 16):
A method comprising:\n receiving, by a node in a wavelength division multiplexing (WDM) system, a first control signal sent by the WDM system, wherein the node comprises an adding unit, the adding unit comprising a colorless optical transmitter coupled to a first waveband filter via a first arrayed waveguide grating, a first optical switch, and a first optical coupler/a first optical combiner coupled to an optical transmission path, wherein the first waveband filter is configured to divide an input optical signal of the first waveband filter into M sub-signals of different wavebands and output the M sub-signals of different wavebands to the first optical switch using M output ends, wherein M is an integer greater than 1; setting, by the node, a switching status of the first optical switch according to the first control signal, such that an output end in the M output ends of the first waveband filter is connected to an input end of the first optical coupler/the first optical combiner through the first optical switch; determining, by the node, a filtering response of the adding unit when the first optical switch is in the switching status that is set; and determining, by the node, a transmission wavelength of the colorless optical transmitter according to the filtering response.
