Abstract :
In recent years, Polymer Optical Fibers (POFS) have been widely used for short-distance communication connections and various estimation applications due to their amplifying properties, large core diameter and high numerical aperture. Be that coplagenuria has made them comfortable. Dispersion is one of the issues that affects the performance of polymer optical fibers and affects and limits the maximum transmission distance and information transfer capacity. For this reason, the study of the phenomenon of scattering in these fibers has become widespread today. In this paper, the scattering of light intensity is measured, and the far and near field patterns, ie for Field and near Field, are obtained for this light scattering, and simulations are performed using a precise computational model based on the wave tracking method. And the location of the conduction scattering intensity in each polymer optical fiber and the far and near field patterns obtained from the output of these fibers are measured and determined by the simulation results, which is more than the average size of the effective non-uniformities leading to scattering. In optical fibers, they are polymerized at about 200 nm, and these non-uniformities occur at the interface between the core and the shell.
