It is shown that solitons exist only under certain conditions and the parameter functions describing dispersion, non linearity and gain or absorption inhomogeneities cannot be chosen independently. Fundamental soliton management regimes for ultra-high speed fiber optics telecommunications are discovered.application/pdfCIENCIA ergo-sum, Revista Científica Multidisciplinaria de ProspectivaMultidisciplinarias (Ciencias Sociales)fiber optics telecommunicationssolitonsArtículo científico
