Power-weighted dispersion distribution function for characterizing nonlinear properties of long-haul optical transmission links

Based on the first-order perturbation theory, we introduce the power-weighted dispersion distribution (PWDD) function to characterize nonlinear properties of fiber-optic transmission links. This technique offers a new perspective on dispersion management for pseudolinear transmission. A rectangular PWDD model is used to describe the formation of ghost pulses analytically in the time domain without relying on the assumption that the pulse shape is Gaussian.
