This paper using the symmetrical split-step Fourier′ method simulates the pulse of high-order solitons transmission characteristic in self-steepening effect and broadening of pulse and spectrum situation.Otherwise,discussed under the existence of self-steepening circumstances,initial positive chirped in the anomalous dispersion section,lead pulse initial narrowing,then there will be strong pulse broadening.The initial negative chirped strengthen pulse broadening.
