Spectral characteristics of step index single mode optical fiber with Kerr nonlinearity

In this paper is described an approximate analytical solution for the fundamental mode of the step-index optical fiber with taking into account the Kerr nonlinearity. The solution is obtained by a known method of Gauss approximation. Based on the obtained analytical solution there were calculated the spectral dependencies of time delay and first and second order chromatic dispersion the parameters for mode 01 LP of the sample of the step-index optical fiber.
