Abstract

Appareil et méthode pour déterminer le passage d'une fibre optique le long d'un chemin d'installation. Un détecteur à l'extrémité d'installation décèle lorsque la lumière est transmise à la fibre à partir d'une source à un endroit prédéterminé. La source peut être une source primaire ou elle peut comprendre un moyen de connexion à une fibre transportant la lumière.
