Abstract
A wavelength selective switch module is disclosed. The wavelength selective switch module includes: a unit for generating test light; a multiplexing unit for multiplexing the test light with the wavelength multiplexed light; a splitting unit for splitting the test light from output light of each of two output ports; a feedback control unit for obtaining deflection control amounts for the deflection unit corresponding to a wavelength of the test light such that a light level of the test light that is split from the output light output from each of the two output ports becomes maximum; and a calculation unit for calculating deflection control amounts for output ports other than the two output ports for the deflection unit for the test light and calculating deflection control amounts for output ports for deflection units of wavelengths included in the wavelength multiplexed light using the deflection control amounts for the deflection unit for the test light output from each of the two output ports by which the light level of the test light becomes maximum.
