Claim 0:
1. An optical cross-connect, comprising an input-end unit, an optical beam-splitting and switching unit, and an output-end unit, wherein
the input-end unit comprises M input ports, the input-end unit is configured to transmit M first light beams in a set of first light beams to the optical beam-splitting and switching unit, and light propagation paths of the M first light beams do not overlap;
the optical beam-splitting and switching unit is configured to split each first light beam in the set of first light beams into Qi second light beams, to obtain a set of second light beams, wherein the set of second light beams comprises Z second light beams, the Z second light beams comprise M groups of second light beams, and each group of second light beams corresponds to one first light beam and comprises Qi second light beams; and i∈[1, M], Z=Q1+Q2+ . . . +QM, Qi>=1, and at least one value of Qi is greater than or equal to 2;
the optical beam-splitting and switching unit is further configured to: perform optical path deflection on each group of second light beams based on a preset optical-path offset parameter set, and transmit, to the output-end unit, the deflected second light beams, wherein an ith group of offset parameters in the optical-path offset parameter set is used to perform optical path deflection on the ith group of second light beams, so that all second light beams in the ith group of second light beams are deflected and then output to Qj output ports of the output-end unit in a one-to-one correspondence manner, wherein j∈[1, M]; and
the output-end unit comprises Z output ports, and the output-end unit is configured to output the Z second light beams.
