ABSTRACT:
There are provided an ASE correction unit which corrects control errors regarding either or both of the gain and the output level of the optical amplifier, which control errors are generated due to the ASE, and an ASE correction controller which controls the correction of the control errors by these ASE correction unit based on a predetermined time constant. Accordingly, the ASE correction errors of the optical amplifier, which performs the ASE correction are suppressed, and stabilization of the output signal light level and the optical amplification gain at the time of changes of the wavelength number can be attained.
