The computer application for the mathematical modeling of optical fibers used in metrology

The article briefly characterizes single mode optical fibers that are not resistant to bending (ITU-T G.652 and G.653) and resistant to bending (ITU-T G.657) and multimode telecommunications optical fibers (ITU-T G.651). The basic mathematical formulas implemented in the application have also been presented, with which the parameters of the designed optical fibers are calculated. The practical part was to create and to test the application enabling the design of single mode and multimode optical fibers of selected refractive index profiles. This paper presents the results of simulations of commonly used telecommunications optical fibers (single mode and multimode). Conclusions regarding the accuracy of calculations performed by the computer application and areas of its applications were formulated.
