Abstract

Intrachannel Four-Wave Mixing（IFWM）is one of the major nonlinearities affecting the signal transmission quality of high-bit-rate long-range dispersion management quasi-linear fiber-optic transmission systems.In this paper

a numerical calculation model is derived for describing the transmission process of quasi-linear fiber-optic transmission systems by adopting the Split-Step Fourier Method（SSFM）and a nonlinear compensation scheme for an economical and effective dispersion management in combination with pulse pre-broadening.After that

the intensity of the ghost pulse at the output end is just a quarter of that before the pre-broadening.Calculation results indicate that this scheme effectively suppresses IFWM

obtains ideal compensation effects and has a certain guiding significance for the design of high-rate fiber-optic communication systems in the future.
