Abstract

L'invention concerne un élément de support de courbure de câble optique consistant en un élément qui supporte plusieurs câbles optiques à l'état courbé au niveau d'un faisceau de fils, et qui comprend un premier élément de courbure et un second élément de courbure. Le premier élément de courbure comprend : une première section de meulage comportant une première surface de meulage qui peut meuler un câble parmi plusieurs câbles optiques à l'état courbé ; une section de fixation qui peut être fixée au faisceau de fils ; et une première section de jonction. Le second élément de courbure comprend : une seconde section de meulage comportant une seconde surface de meulage qui peut meuler un câble différent parmi plusieurs câbles optiques à l'état courbé ; et une seconde section de jonction. La première section de jonction et la seconde section de jonction sont formées de manière à être jointes de sorte que la position dans la direction de jonction du premier élément de courbure et du second élément de courbure puisse être ajustée.
