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 17):
The method according to claim i 6 , further comprising:\n receiving, by the node, a second control signal sent by the WDM system, wherein the node further comprises a first dropping unit, the first dropping unit comprising: N second optical switches coupled to a second waveband filter, a first optical multiplexer and a second optical multiplexer, respectively, and a first colorless optical receiver coupled to the first optical multiplexer via a second arrayed waveguide grating, wherein the second waveband filter is configured to divide an input optical signal of the second waveband filter into N sub-signals of different wavebands and output the N sub-signals of different wavebands to the N second optical switches respectively using N output ends, and N is an integer greater than  1 , and wherein an input end of the second waveband filter and an output end of the second optical multiplexer are coupled to the optical transmission path; setting, by the node, a switching status of each second optical switch according to the second control signal, and determining, by the node, whether a sub-signal output by an output end of the second waveband filter is transmitted to the first optical multiplexer or to the second optical multiplexer through a corresponding second optical switch based on the switching status of the corresponding second optical switch; performing, by the node, multiplexing processing on a first optical signal that is input into the first optical multiplexer, and determining, by the node, a receiving wavelength of the first colorless optical receiver according to the first optical signal; and performing, by the node, multiplexing processing on a second optical signal that is input into the second optical multiplexer, and coupling, by the node, the second optical signal to the optical transmission path.
