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 10):
A node in a point-to-point WDM system, wherein the node comprises:\n a 1:2 waveband filter configured to divide an input optical signal of the 1:2 waveband filter into two sub-signals of different wavebands, wherein the two sub-signals of different wavebands are respectively output by two output ports of the 1:2 waveband filter; a 2:2optical switch having two first ports and two second ports; a colorless optical transmitter; a colorless optical receiver; a first arrayed waveguide grating; and a second arrayed waveguide grating; wherein a common port of the 1:2 waveband filter is coupled to an optical transmission path, and the two output ports of the 1:2 waveband filter are respectively coupled to the two first ports of the 2:2 optical switch; wherein one second port of the 2:2 optical switch is coupled to a transmit end of the colorless optical transmitter via the first arrayed waveguide grating, and the other second port of the 2:2 optical switch is coupled to a receive end of the colorless optical receiver via the second arrayed waveguide grating; and wherein the 2:2 optical switch is configured to switch between a bar state and a cross state according to a control signal, such that the 2:2 optical switch passes a sub-signal of the two sub-signals to the first arrayed waveguide grating or the second arrayed waveguide grating according to a state of the 2:2 optical switch.
