Abstract
L'invention concerne les dispositifs qui permettent de multiplexer sur une même fibre optique multimode plusieurs sources lumineuses de longueurs d'ondes différentes. Elle consiste à raccorder ces sources à des fibres optiques monomodes. L'extrémité libre de ces fibres est alors taillée en cône de faible pente et ces cônes sont fixés en couronne autour de l'extrémité de la fibre multimode. Elle permet d'obtenir un multiplexeur simple et robuste.
