摘要： An apparatus, method and computer program product for controlling pumping light powers for a multiple-wavelength-pumped Raman amplifier that is pumped by pumping lights from a plurality of pumping light sources, by measuring gain wavelength characteristic or signal-power wavelength characteristic of the multiple-wavelength-pumped Raman amplifier using a plurality of photodetectors having different wavelength-sensitivity characteristics. The apparatus includes a determining unit that estimates a power of each of signal channels in a wavelength band for use based on values monitored by the photodetectors, and determines the pumping light powers using the power of each of the signal channels estimated. The determining unit estimates the power of each of the signal channels by performing an interpolation of the values monitored by the photodetectors.
