Ultrashort pulse propagation at =1.55 microm in polarization maintaining dispersion shifted fiber is experimentally analyzed using cross-correlated frequency resolved optical gating (X-FROG). The generated soliton pulse is picked out with the spectral filter and is used as the probe pulse. The temporal distributions of the spectral components in the generated pulses are observed. The initial process of the pulse breakup is directly observed for the first time. The results of X-FROG traces are in agreement with the measured cross-correlation traces and the optical spectra. It is shown that the generated soliton pulse and the anti-stokes pulse are partially overlapped and almost copropagate along the fiber.
