Claim 5:
6. The optical cross-connect according to claim 2, wherein
a first collimation-lens array is disposed between the input-end unit and the optical beam-splitting and switching unit, and a second collimation-lens array is disposed between the optical beam-splitting and switching unit and the output-end unit;
an interval between the first optical beam-splitting and switching module and the first collimation-lens array is a collimator distance of the first collimation-lens array, so that a waist of a light spot of each of the first light beams is mapped onto a surface of the first optical beam-splitting and switching module; and
an interval between the second optical switching module and the second collimation-lens array is a collimator distance of the second collimation-lens array.
