Kind Code:
B2
Abstract:
In order to enable easy adjustment of loss wavelength characteristics in accordance with the characteristics of a wavelength division multiplex optical signal, and the usage environment of an EDFA, etc., an equalizer 10 is provided with: a wavelength selection switch unit 20 that adds a loss profile that has been set to an inputted wavelength division multiplex optical signal, and outputs the same; and a setting unit 30 that sets the loss profile to a wavelength selection switch means on the basis of obtained setting information. The setting information is information for flattening the spectrum of the outputted wavelength division multiplex optical signal.
