This work is concerned with application of earlier on developed an alternative method for simulation of piecewise regular multimode fiber optic links operating in a few-mode regime for computation of laser-excited optical pulse dynamics during its propagation over irregular silica graded-index multimode optical fibers (MMFs) with extremely large core diameter. Proposed model is based on the piecewise regular representation, and it takes into account launching 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- and macro-bends. We present some results of simulation 10GBase-LX optical signal transmission over 100-mu m-core MMFs graded-index refractive index profile corresponding to the typical laser-optimized MMFs 50/125 of ISO/IEC Cat. OM2+/OM3 scaled up to 100 mu m core.
