Abstract

L'invention concerne un procédé de production d'un module optique comprenant : une étape P1 de fixation d'élément durant laquelle une extrémité d'incidence d'une fibre optique 50 et un élément optique contenant une source de lumière sont disposés sur une plaque de base 2, qui sert de plaque de fond d'un boîtier, de sorte que de la lumière émise par la source de lumière disposée sur la plaque de base 2 soit incidente sur la fibre optique 50; et une étape P2 de fixation de corps de cadre durant laquelle un corps de cadre 32, qui sert de paroi latérale du boîtier, est fixé sur la plaque de base 2 de façon à entourer l'élément optique et l'extrémité d'incidence de la fibre optique. Le corps de cadre 32 est pourvu d'une découpe 35a permettant de faire sortir la fibre optique à partir de celle-ci. Suite à la fixation du corps de cadre 32 sur la plaque de base 2 par vissage lors de l'étape P2 de fixation de corps de cadre, l'espace qui sépare le corps de cadre 32 et la fibre optique 50 de la découpe 35a permettant la sortie de la fibre optique est scellé au moyen d'une douille élastiquement déformable 55.
