Claim 2:
3. The optical cross-connect according to claim 2, wherein
the optical beam-splitting module comprises M input areas and M output areas that are in a one-to-one correspondence with the M input areas; and the M input areas of the optical beam-splitting module are configured to receive respectively the M first light beams in the set of first light beams, and an Xth output area of the optical beam-splitting module is configured to output QX second light beams obtained by splitting an Xth first light beam, wherein X∈[1, M];
the first optical switching module comprises M deflection areas, the second optical switching module comprises Z deflection areas, the Z deflection areas comprise M deflection area groups, and each ith deflection area group comprises Qi deflection areas; the M output areas of the optical beam-splitting module are in a one-to-one correspondence with the M deflection areas of the first optical switching module; the M deflection areas of the first optical switching module are in a one-to-one correspondence with the M deflection area groups of the second optical switching module; and the Z deflection areas of the second optical switching module are in a one-to-one correspondence with the Z output ports of the output-end unit;
the QN first deflection angles that correspond to the Nth input port and that are determined based on the Nth group of offset parameters in the optical-path offset parameter set are used, so that QN second light beams that are deflected and that are output from the Nth deflection area of the first optical switching module correspond to QN deflection areas from the Nth deflection area group of the second optical switching module; and
the QN second deflection angles that correspond to the Nth input port and that are determined based on the Nth group of offset parameters in the optical-path offset parameter set are used, so that the QN second light beams that are deflected again and that are output from the Nth deflection area group of the second optical switching module are in a one-to-one correspondence with the QN output ports of the output-end unit.
