We have presented a complete and thorough experimental study of supercontinuum (SC) evolution processing in dispersion shifted fiber (DSF). When the pump power is relatively low, the SC spectrum is asymmetrically broadened toward the zero dispersion wavelength of DSF due to self-phase modulation and group velocity dispersion. When the broadened spectrum spans the zero dispersion wavelength, cross-phase modulation and four-wave mixing cause symmetrical spectrum broadening. Stimulated Raman scattering causes the spectrum to broaden toward the long wavelength quickly when pump power is intense enough.
