Comparison of power and Fourier spectrum between theory, simulation and experiment at fixed distance. The data corresponds to horizontal cuts in Fig. 3. (a) Waveform measured in back-to-back configuration compared to the theoretical solution (2) and NLSE simulation. (b) The associated Fourier spectrum. (c) Waveform measured after 2925 km (39 spans) at the point of maximal temporal compression. (d) The Fourier spectrum is taken at the point of maximal spectral broadening and shows the typical triangular shape.
