Hi Abu Bakar,
in Agrawal book, “nonlinear fiber optic” there is a chapter 5 titled “Optical Soliton”. this chapter has many experiments data for soliton propagation.
here is some parameter of one experiment,
gamma 1.3 W^-1.Km^-1, core diameter 9.3 um, 1.55 um wavelength, peak input power is 1 W.
please check all the other parameters of dispersion as well.
thanks
Mohamed
