An apparatus comprising:
- a processor configured to calculate a noise figure of an optical amplifier for a plurality of selected wavelength channels in a partial-fill scenario that accounts for channel loading,
- wherein the noise figure is calculated using a plurality of corresponding noise figure correction values at a plurality of wavelengths based on an effective number of channels.
A system for correcting amplifier gain, comprising:
- a correction component on a non-transitory computer readable media executable by a processor configured to calculate a gain correction for a gain caused by an optical amplifier for a plurality of selected wavelength channels in a partial-fill scenario that accounts for channel loading,
- wherein the gain correction is based on a spectral hole burning effect model that is calculated for a range of wavelengths based on a number of the selected wavelength channels.
A computer implemented method comprising:
- calculating with a processor an effective number of channels for a plurality of wavelengths;
- calculating with a processor a noise figure correction for the wavelengths based on the effective number of channels;
- and
- adjusting with a processor a noise figure that corresponds to an optical amplifier using the noise figure correction.
