Numerical analysis of quasi-soliton propagation properties using dispersion compensation

ZHAO Chao-feng; LU Xun; LUO Shao-peng

For quasi-soliton propagating steadily in standard monomode fiber,its transmission in a standard monomode fiber and dispersion compensation fiber is studied with the split-step Fourier method.The transmission characteristics in a standard monomode fiber and dispersion compensation fiber are obtained.The numerical analysis shows that its peak value descends and its width broadens when it propagates in a standard monomode fiber,so the quasi-soliton can't propagate steadily.When it propagates in a dispersion compensation system using dispersion compensation technique,its shape can be kept almost the original shape,so quasi-soliton propagation properties can be improved greatly than in a standard monomode fiber.
