Abstract
A method for measuring a wavelength channel tuning time by using an optical filter that converts a change of an output wavelength of a tunable device into an optical intensity change, and a system thereof. The system for measuring a wavelength channel tuning time includes: an optical filter set configured to convert a wavelength change of an optical tunable device into an optical output intensity change; at least one or more optical electric converters configured to convert the optical output intensity change output by the optical filter set into an electric signal; and a controller configured to generate a wavelength change command applied to the tunable device, so as to calculate a wavelength channel tuning time of the tunable device by using the wavelength change command and the electric signal output by the optical electric converter.
