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 5):
The node in the WDM system according to  claim 1 , wherein the node further comprises a second dropping unit, the second dropping unit comprising:\n a third waveband filter configured to divide an input optical signal of the third waveband filter into K sub-signals of different wavebands, wherein K is an integer greater than 1, and the K sub-signals of different wavebands are respectively output by K output ends of the third waveband filter; K third optical switches coupled to the K output ends of the third waveband filter; a third optical multiplexer; a third arrayed waveguide grating; and a second colorless optical receiver; wherein an input end of the third waveband filter is coupled to the optical transmission path, and each of the K third optical switches is configured to determine, according to a third control signal, whether to connect an output end in the K output ends of the third waveband filter to an input end of the third optical multiplexer so that a sub-signal output by the output end is passed to the third optical multiplexer; and wherein the third optical multiplexer is configured to perform multiplexing processing on an input signal of the third optical multiplexer, and an output end of the third optical multiplexer is coupled to a receive end of the second colorless optical receiver via the third arrayed waveguide grating.
