Claim 1:
2. The optical cross-connect according to claim 1, wherein the optical beam-splitting and switching unit comprises a first optical beam-splitting and switching module and a second optical switching module, and the first optical beam-splitting and switching module comprises an optical beam-splitting module and a first optical switching module, wherein
the optical beam-splitting module is configured to: split, into Qi second light beams, a ith first light beam that is received from each input port and that is in the set of first light beams; and transmit, to the first optical switching module, the Qi second light beams obtained by splitting each first light beam;
the first optical switching module is configured to deflect respectively, based on Qi first deflection angles corresponding to the ith input port of the M input ports, direction angles of Qi second light beams, so that the Qi second light beams that are deflected and that correspond to the ith input port of the M input ports are separately output to the second optical switching module, wherein Qi first deflection angles corresponding to one input port are in a one-to-one correspondence with the Qi second light beams obtained by splitting the first light beam transmitted from the input port; and
the second optical switching module is configured to deflect, based on Qi second deflection angles corresponding to the ith input port of the M input ports, direction angles of the received Qi second light beams that are deflected once and each second light beam that is deflected again is output to a corresponding output port of the output-end unit; wherein
for any ith input port, the Qi first deflection angles and the Qi second deflection angles that correspond to the ith input port are determined based on an ith group of offset parameters in the optical-path offset parameter set, wherein i∈[1, M].
