Abstract
An optical amplifier control apparatus according to the present invention includes control circuit; optical amplifiersrespectively located on paths; a plurality of light sourcesthat output excitation lights that differ in light intensity; and optical switchthat changes optical routes of excitation lights that are output from light sourcesand inputs the excitation lights to optical amplifiersas determined by control circuit. Control circuitis provided with determination sectionthat determines which paths to allocate which excitation lights that differ in light intensity based on a parameter that relates to wavelength lights on a plurality of paths when wavelength lights of WDM signal light that propagate to one of the plurality of paths are optically amplified.
