We discuss the propagation of nonlinear optical pulses in fibers. The wave equation is solved taking the radial dependence in an average way. The radius versus wavelength curves for “no dispersion” in SiO2 glass are calculated and plotted. These no-dispersion curves separate the regions of light and dark solitons supported by the fibers.
