The NSR estimation can only be performed at reception, whereas the power spectral density approach can be performed along the optical link if a high resolution Optical Spectrum Analyzer is available.

Finally, we show how a single notch spectrum can be used to detect and compensate for impairments, and we perform skew estimation as an example.

Perturbed spectra are modelled to estimate OSNR for a single channel amplified link.
