A distribution management optical fiber which can be manufactured easily and connected to another optical fiber easily, etc. The distribution management optical fiber is a quartz optical fiber which has a secured single mode at a predetermined wavelength within a signal wave band, and is composed of 1st parts with positive wavelength distributions and 2nd parts with negative wavelength distributions which are alternately arranged adjacent to each other. The distribution management glass fiber has a uniform additive concentration in a longitudinal direction and, on the other hand, the refractive indices or residual stresses of glass layers to which GeO2 is not added as an additive are adjusted so as to correspond to the 1st and 2nd parts.
L'invention porte sur une fibre optique à gestion de distribution qui peut ête fabriquée et raccordée facilement à une autre fibre optique. La fibre optique à gestion de distribution est une fibre de quartz qui présente un mode unique sécurisé, à une longueur d'onde prédéterminée, dans une gamme d'ondes de signaux et qui est composée de premières parties à distributions de longueurs d'onde positives et de secondes parties à distributions de longueurs d'onde négatives, disposées alternativement adjacentes les unes aux autres. La fibre de verre à gestion de distribution a une concentration d'additifs uniforme dans un sens longitudinal et, d'un autre côté, les indices de réfraction ou contraintes résiduelles des couches de verre auxquelles GeO2 n'a pas été ajouté comme additif sont ajustés de façon à correspondre aux premières et secondes parties.
