We measure the waveform and phase curves of short optical pulses before and after transmission over different lengths of fibers by use of the pulse analyzer with the frequency-resolved optical gating (FROG), and numerically simulate pulse evolution under the experimental conditions. The nonlinear coefficient of the fiber is given by comparing the experimental results with the numerical ones. Difference between the experiment and numerical simulation is analyzed.
