Claim 14:
15. The optical cross-connect according to claim 11, wherein
a first collimation-lens array is disposed between the input-end unit and the polarization splitting apparatus, and a second collimation-lens array is disposed between the polarization combining apparatus and the output-end unit;
a distance between the first optical beam-splitting and switching apparatus and the first collimation-lens array is a collimator distance of the first collimation-lens array, so that waists of light spots of a third light beam and a fifth light beam that correspond to each of the first light beams are mapped onto a surface of the first optical beam-splitting and switching apparatus; and
a distance between the second optical switching apparatus and the second collimation-lens array is a collimator distance of the second collimation-lens array.
