Abstract

L'invention concerne un dispositif de dérivation pour détecter la lumière parcourant une fibre optique. Une partie de la lumière guidée dans le coeur de grand diamètre d'une fibre optique passe dans la gaine d'une autre fibre de diamètre de coeur plus petit soudée coaxialement à l'extrémité de la première fibre, et cette partie est transmise de cette gaine à un détecteur par l'intermédiaire d'un adaptateur optique, la lumière guidée dans l'autre direction passant presque sans perte du coeur de petit diamètre au coeur de grand diamètre. Application aux télécommunications.A shunt device for detecting light passing through an optical fiber is disclosed. Part of the light guided into the large diameter core of one optical fiber passes through the cladding of another smaller core diameter fiber coaxially soldered to the end of the first fiber, and that part is transmitted from this sheath to a detector via an optical adapter, with light guided in the other direction passing almost without loss from the small diameter core to the large diameter core. Application to telecommunications.
