%X The propagation equation of Gaussian pulse is theoretical derived considering second-,third-,fourth-order dispersion(FOD).The influence of FOD on propagation properties of femtosecond Gaussion pulse in Singlemode optical fiber is mostly considered.The numerical simulation results show that the influence of FOD towards pulse is obvious only when input pulse width is quantitatively femtosecond corresponding high-velocity transmission.The aberration characteristic of pulse shape coming of FOD is different from SOD and TOD.With input pulse width being gradually diminished,Femtosecond Gaussian pulse undergoes a variation from only being broadened,to two sides of broadened pulse appearing a pedestal,then the pedestal having a small oscillation.
