Modeling the effects of material dispersion in fiber-optic communication lines

摘要

A model of the dependence of the refractive index on frequency in the form of a power polynomial is proposed. A high accuracy of such an approximation of the three-term Selmeyer formula is shown. A refined method of dynamic modeling of the effects of material dispersion is considered. Dependencies of the dispersion characteristics on the shape of the signal and the composition of the material of optical fibers are shown. Refined dispersion parameters of signals in fiber-optic communication lines are proposed.
