Numerical and experimental investigation of power and wavelength margins for a 20-Gb/s dispersion-managed soliton transmission system on standard fiber

A good agreement has been found between numerical and experimental investigation of a 20-Gb/s dispersion-managed soliton transmission system on standard fiber. More than 6 dB of power margin over 30 nm has been obtained at 1100 km by improving the dispersion slope compensation and the prechirping.
