Claim 4:
5. The optical cross-connect according to claim 4, wherein the optical beam-splitting and switching unit further comprises an optical-path conversion module;
the optical-path conversion module comprises one or more lenses, and is disposed parallel to the first plane and on an optical path through which the set of second light beams is transmitted from the first optical beam-splitting and switching module to the second optical switching module; and
an equivalent center of the optical-path conversion module is located on a connection line between a center of the first optical beam-splitting and switching module and a center of the second optical switching module, an interval between the optical-path conversion module and the first optical beam-splitting and switching module is an equivalent focal length of the optical-path conversion module, and an interval between the optical-path conversion module and the second optical switching module is an equivalent focal length of the optical-path conversion module; and the center of the first optical beam-splitting and switching module is a center of the M deflection areas of the first optical switching module, and the center of the second optical switching module is a center of the Z deflection areas of the second optical switching module.
