A single mode optical fiber including a first core (300) having a constant refractive index (n1) within a predetermined radius (a1) from the center of an optical fiber, a second core (302) which covers the first core (300) and has a refractive index (n2) which decreases form the refractive index (u1) of the first core (300) with an increase in its radius, and a cladding (304) which covers the second core (302) and has a refractive index (u0) smaller than the minimum refractive index of the second core (302). Accordingly, the core structure of an optical fiber is controlled, and the optical fiber has a refractive index distribution being a complex of a staircase type having low dispersion and a triangular type having low loss, thus manufacturing an optical fiber having low dispersion and low loss.

L'invention concerne une fibre optique monomode comprenant un premier coeur (300) possédant un indice de réfraction (n1) constant dans un rayon (a1) prédéterminé à partir du centre d'une fibre optique; un deuxième coeur (302) couvrant le premier coeur (300) et possédant un indice de réfraction (n2) diminué par rapport à l'indice de réfraction (n1) du premier coeur (300) avec une augmentation de son rayon; et une gaine (304) couvrant le deuxième coeur (302) et possédant un indice de réfraction (n0) inférieur à l'indice de réfraction minimal du deuxième coeur (302). La présente invention permet ainsi de réguler la structure du coeur d'une fibre optique possédant une répartition d'indices de réfraction constituée d'un complexe formé d'un type en escalier à faible dispersion et d'un type triangulaire à faible perte, la fibre optique ainsi fabriquée présentant une faible dispersion et une faible perte.
