Abstract :
We present an analytical approximation that can describe the signal at the output of a nonlinear fiber, accounting for the distortions induced by the interplay between chromatic dispersion and Kerr nonlinearity. The obtained results agree well with the split-step Fourier method for launch powers as high as 10 dBm.
