Abstract

L'invention concerne un élément mélangeur optique, du type dans lequel deux faisceaux de fibres optiques sont reliés entre eux par une voie mélangeuse. Il comporte un faisceau de fibres optiques qui sont réunies, sur un côté, par fusion et sans laisser d'interstice, la partie ainsi réunie présentant une forme s'amincissant progressivement Application aux systèmes de communications par voie optique
