An optical amplifier control apparatus according to the present invention includes control circuit 300; optical amplifiers 4, 5 respectively located on paths; a plurality of light sources 200, 201 that output excitation lights that differ in light intensity; and optical switch 32 that changes optical routes of excitation lights that are output from light sources 200, 201 and inputs the excitation lights to optical amplifiers 4, 5 as determined by control circuit 300. Control circuit 300 is provided with determination section 301 that 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. |
