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 2):
The node in the WDM system according to  claim 1 , wherein the node further comprises a first dropping unit, the first dropping unit comprising:\n a second waveband filter configured to divide an input optical signal of the second waveband filter into N sub-signals of different wavebands, wherein N is an integer greater than 1, and the N sub-signals of different wavebands are respectively output by N output ends of the second waveband filter; N second optical switches coupled to the second waveband filter; a first optical multiplexer coupled to the N second optical switches; a second optical multiplexer coupled to the N second optical switches; a second arrayed waveguide grating; and a first colorless optical receiver; and wherein an input end of the second waveband filter is coupled to the optical transmission path, and each of the N second optical switches is configured to connect an output end in the N output ends of the second waveband filter to an input end of the first optical multiplexer or an input end of the second optical multiplexer according to a second control signal, such that a sub-signal output by the second waveband filter is transmitted to the first optical multiplexer or the second optical multiplexer through a corresponding second optical switch; wherein the first optical multiplexer is configured to perform multiplexing processing on an input signal of the first optical multiplexer, and an output end of the first optical multiplexer is coupled to a receive end of the first colorless optical receiver via the second arrayed waveguide grating; and wherein the second optical multiplexer is configured to perform multiplexing processing on an input signal of the second optical multiplexer, and an output end of the second optical multiplexer is coupled to the optical transmission path.
