Simulation of Dispersion Managed Solitons in Optical Fibers on Dense Cards with Local Nonlinearity

This paper presents the results of modeling the propagation of a triplet of solitons controlled by dispersion on dense maps with local nonlinearity in optical fibers of a fiber-optic communication line with a length of up to 10,000 km. It is shown that the inclusion on the dispersion map between optical fibers with a dispersion of the opposite sign of a nonlinear element with an inverse phase characteristic makes it possible to increase the length of the fiber-optic line, which supports the propagation of a triplet of solitons more than 2 times, and the dynamic range of the fiber-optical communication line is more than on 3dBm.
