And when the maximum wavelength power and the minimum wavelength power are obtained, calculating the maximum wavelength power and the minimum wavelength power to obtain the flatness of the preset OMS section. For example, when the maximum wavelength power and the minimum wavelength power are obtained, subtracting the minimum wavelength power from the maximum wavelength power results in the flatness of the preset OMS segment.
