Abstract

Dispositif de jonction de fibres optiques permettant une transmission et une détection combinees de signaux optiques transmis par une seule fibre. Ce dispositif permet la transmission de signaux optiques dans deux sens, sur une seule fibre. Il comprend un boîtier traversé par un canal allongé dans lequel deux fibres optiques sont fixees bout à bout de manière qu'une certaine perte de lumière se produise au passage de ladite lumière d'une fibre à l'autre. Cette perte de lumiere est détectée par un élément photosensible fixé sur le boîtier. Domaine d'application : transmission de signaux par fibres optiques.
