Abstract：
 A method for the dynamic balance of the wavelength dividing multiplexing system channel power and an equalizing optical amplifier belong to the technology field of the high speed broadband fiber communication and the optical amplifier. The invention is characterized by utilizing the linear relationship between the channel power variation and the strain of the pumping power and the light attenuation, and integrating the mechanism of flatting the grain spectrum and regulating the grain range and the light amplification. It realizes the flatness of the dynamic gain spectrum and maintains the equalization and the invariableness of the multi-channel output power at the same time. It can be designed independently according to the anticipated system parameters, and is fit for the point-to-point multiple system and the dynamic power balance of the light network simultaneously.
