    摘要: A contrivance, if a WDM signal state changes, is to improve an optical transmission quality by compensating gain flatness. A first excitation control unit sets a first optical pumping light source unit to emit excitation power needed to get the same amplifying operating level of a first amplifying medium as at the time of a maximum wavelength count when allocating wavelengths after a change in wavelength count at an equal interval in a wavelength range. A wavelength allocation bias estimation unit compares a present monitor value of optical power after outputting of a gain equalizer 13 with wavelength equi-allocation power associated with the recognized wavelength count, and thus estimates a wavelength allocation bias occurred as a concomitant of the change in the wavelength count. A primary gradient calculation unit obtains a primary gradient quantity defines as a gain deviation from the wavelength allocation bias. A second excitation control unit sets, in a second optical pumping light source unit, the excitation power needed to cancel the primary gradient quantity. An attenuation quantity control unit controls a variable optical attenuator to fix a gain by compensating an amount of change in the sum of gains.

    摘要: An optical amplifier of the present invention comprises: first and second optical amplifying sections connected in series to each other between an input port and an output port; a first variable optical attenuator arranged on a former stage of the first optical amplifying section; a second variable optical attenuator arranged between the first and second optical amplifying sections; an optical amplification control section that controls the first and second optical amplifying sections; and an optical attenuation control section that controls the first and second variable optical attenuators. The optical amplification control section controls each of the optical amplifying sections so that a gain of the entirety of the optical amplifier is held constant, and the optical attenuation control section controls attenuation amounts of the variable optical attenuators so that monitor values of the output powers from the variable optical attenuators approximate the same value, provided that a value of the sum of the attenuation amounts of the variable optical attenuators decided according to the signal light input power per one wavelength of a WDM light is held constant. As a result, it becomes possible to provide at a low cost the optical amplifier capable of achieving flat output wavelength characteristics and the favorable NF, irrespective of the signal light input power per one wavelength of the WDM light and the number of wavelengths thereof.
