Claim 6:
7. The method according to claim 6, wherein the wavelength-selective switch comprises a first wavelength-selective switch, the first wavelength-selective switch comprises a first input port and more than one first output port, and the first output port is connected to the filter;
the receiving, by a wavelength-selective switch in each optical signal processing device, inputted dense wavelength division multiplexing optical signals comprises:
receiving, by the first wavelength-selective switch through the first input port, the dense wavelength division multiplexing optical signals inputted in an ingress direction; and
the performing, by the wavelength-selective switch, wavelength-based allocation on the dense wavelength division multiplexing optical signals, and inputting the optical signals after the wavelength-based allocation into a filter in each optical signal processing device comprises:
allocating, by the first wavelength-selective switch, the dense wavelength division multiplexing optical signals to different first output ports according to wavelengths.
