Abstract

a invenção se refere a um link óptico compreendendo n fibras ópticas, com n = 2. cada fibra óptica compreende um núcleo óptico e um revestimento óptico que cerca o núcleo óptico, o núcleo óptico apresentando um único perfil de índice graduado ai com ai = 1, e o núcleo óptico apresentando um raio ri1, em que i e [1;n] é um índice que designa a dita fibra óptica. o dito revestimento óptico compreende uma região de índice refrativo reduzido ntrenchi, chamada de vala, que cerca o núcleo óptico. de acordo com as realizações da invenção, para todas as fibras ópticas no dito link, o dito raio do núcleo óptico r1i e o dito comprimento li são selecionados de maneira que r1i = 13,5 µm e de maneira a atender um critério c de qualidade. assim, a invenção provê um link de fibra óptica de poucos modos, que permite guiar um maior número de modos lp em comparação aos links de fmf da técnica anterior enquanto alcança um adiamento de grupo de modo diferencial baixo.
