Abstract: The optical switch includes: a spectroscopic device (12) which separates wavelength division multiplexed (WDM) light into its component wavelengths; and a plurality of movable reflectors (41), arranged in a spectral direction at different intervals, for reflecting light of an individual component wavelength separated by said spectroscopic device (12). With this optical switch, deterioration of the characteristic of the pass band is avoided, so that the pass band characteristic is increased.
