Claim 7:
8. The method according to claim 7, wherein the filter comprises a downlink input port and more than one downlink output port corresponding to the downlink input port;
the separating, by the filter, the optical signals after the wavelength-based allocation into single-channel optical signals, and inputting the single-channel optical signals into upper ports of the optical cross-connect device comprises:
receiving, by the filter through the downlink input port, the optical signals after the wavelength-based allocation outputted from the first output port; and
separating, by the filter, the optical signals after the wavelength-based allocation into more than one single-channel optical signal, and outputting the more than one single-channel optical signal to the upper ports of the optical cross-connect device through the more than one downlink output port.
