Abstract

Fibra óptica que comprende: Una zona central constituída por un material vítreo reforzado que está adaptada para absorber radiaciones con una primera longitud de onda y suministrar amplificación con una segunda longitud de onda; una primera capa de revestimiento con un margen exterior y que está dispuesta alrededor de dicha zona central, contando la citada primera capa de revestimiento de una serie de irregularidades por lo menos alrededor del citado límite exterior; y una segunda capa recubridora con un márgen interior y otro exterior, ajustándose dicha capa interior a la capa exterior de la primera capa recubridora mencionada.Optical fiber comprising: A central zone consisting of a reinforced vitreous material that is adapted to absorb radiation with a first wavelength and provide amplification with a second wavelength; a first coating layer with an outer margin and which is disposed around said central zone, said first coating layer having a series of irregularities at least around said outer limit; and a second coating layer with an inner and an outer margin, said inner layer being adjusted to the outer layer of the first mentioned coating layer.
