This work presents results of simulation of Gaussian and non-Gaussian pulse propagation over irregular weakly guiding silica graded-index laser-optimized multimode optical fiber of ISO/IEC 11801 Cat. OM2+/OM3 operating in a few-mode regime under strong mode coupling and both centered and offset launch conditions. We utilized recently proposed model of irregular few-mode fiber optic link been introduced in the previous works, which is based on split-step method approach combined with piece-wise regular representation. Model takes into account launch conditions, differential mode delay, both lower- and higher-order mode chromatic dispersion, differential mode attenuation, mode mixing and power diffusion occurring due to real fiber irregularity and micro-/macro-bends. Parabolic and triangular as well as Gaussian and sech2-shape laser-excited optical pulse propagation over conventional silica laser-optimized multimode fiber under various launch conditions was simulated and researched. Some results of simulated pulse dynamics comparison analysis are represented.
