To optimize the number of optical gate switches required by an optical switching apparatus which comprises an optical space switch and wavelength selectors, the following process as a preliminary process of introducing optical signals into the optical space switch, is carried out. In detail, the preliminary process is optically converting the optical signals in relation to the number of input ports of the optical space switch, by optically processing the optical signals. As the results, the number of processed optical signals responding to the input ports and the processed number of wavelengths of each processed optical signal is equal to each other, and thereby, the optimization is achieved.
