Abstract:

Examed the properties of dipersion-managed soliton. Dispersion-managed soliton propagation and interaction in optical fibers is simulated by numerical calculation.It is noticed if there is little difference between local dipersion and average dispersion,it is better to insert the pulse with shape as hyperbolic secant;if increase the differences of local dipersion and average dispersion, the shape of the pulse transformed as gauss.Dispersion become the main factor of dispersion-managed soliton interaction.

Key words: optical communication, soliton interaction, numerical simulation, local dispersion, average dipersion
