Claim 9:
10. The method according to claim 9, wherein the wavelength-selective switch comprises a second wavelength-selective switch, the second wavelength-selective switch comprises a second output port and more than one second input port, and the filter comprises an uplink output port and more than one uplink input port corresponding to the uplink output port;
the multiplexing, by the filter, the inputted more than one single-channel optical signal, and inputting multiplexed optical signals into a wavelength-selective switch in the optical signal processing device comprises:
multiplexing, by the filter, the single-channel optical signals inputted from the more than one uplink input port into the same optical channel, and outputting, through the uplink output port, the multiplexed optical signals into the second input port of the second wavelength-selective switch; and
the performing, by the wavelength-selective switch, wavelength combination on the multiplexed optical signals and outputting the optical signals comprises:
combining, by the second wavelength-selective switch, optical signals inputted from all of the second input ports into dense wavelength division multiplexing optical signals, and outputting the dense wavelength division multiplexing optical signals in an egress direction through the second output port.
