There is provided an apparatus capable of reducing a waveform distortion of an outgoing light when the light of an optical wavelength in a certain specific narrow range is incident upon an optical fiber. The apparatus comprises an optical source system 10 supplying an incident light to an optical fiber line 110, a waveform monitor 42 measuring a waveform distortion of a transmitted light which the incident light transmits the optical fiber line 110, and an optical output adjusting unit 44 adjusting an output of the incident light to enter the waveform distortion which the waveform monitor 42 measures within a predetermined range. By adjusting the output of the incident light, a ratio to noise, that is, a S/N ratio is lowered. A noise is existed within a range of wide wavelength relatively. Accordingly, if the S/N ratio is lowered properly, the incident light of which the wavelength is in a wide range can be supplied to the optical fiber line 110. Therefore, it is possible to reduce a waveform distortion of an outgoing light.
