The pulse profile,pulse width of the chirped picosecond soliton after long distance adiabatic transmission in standard fiber are experimentally inverstigated by use of SHG-FROG analyzer.The experimental results show that the chirped N=1 soliton pulses can adiabatically transmit over 1 000 dispersion length with the stable profile,which shows that the influence of frequency chirp and fiber loss on soliton profile is little;But the broadening of soliton pulses with chirp is more larger than that without chirp...
