Abstract

La présente invention concerne un câble de fibre optique dépourvu de film coloré, qui nécessiterait un allongement du temps de production, et permettant de distinguer facilement les unités optiques voulues pendant un branchement à mi-longueur. Un câble de fibre optique est formé en recouvrant d'un enrobage une unité optique (3) dans laquelle un cœur en ruban fixé de manière discontinue (6) présentant des marques (13) est logé dans un tube transparent (7). L'unité optique (3) se distingue par le type particulier de marques (13) formées sur le cœur en ruban fixé de manière discontinue (6). Le type particulier de marques (13) de l'unité optique (3) permet donc de la distinguer quand une partie partiellement le long du câble est séparée pour être visible pendant un branchement à mi-longueur.
