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 18):
The method according to  claim 16 , further comprising:\n receiving, by the node, a third control signal sent by the WDM system, wherein the node further comprises a second dropping unit, the second dropping unit comprising K third optical switches coupled to a third optical multiplexer, a second colorless optical receiver coupled to the third optical multiplexer via a third arrayed waveguide grating, and a third waveband filter coupled to the optical transmission path, wherein the third waveband filter is configured to divide an input optical signal of the third waveband filter into K sub-signals of different wavebands and output the K sub-signals of different wavebands to the K third optical switches, respectively; setting, by the node, a switching status of each of the K third optical switches according to the third control signal, and determining, by the node, whether or not a sub-signal output by the third waveband filter is transmitted to the third optical multiplexer through a corresponding third optical switch based on the switching status of the corresponding third optical switch; performing, by the node, multiplexing processing on an optical signal that is input into the third optical multiplexer; and determining, by the node, a receiving wavelength of the second colorless optical receiver according to the optical signal.
