Abstract

Elément de connecteur pour fibre optique, avec élargissement de faisceau par lentille. Selon l'invention, la lentille 32 est montée dans l'alésage antérieur d'un embout 31 comportant une ou plusieurs surfaces de référence utilisées, de façon connue, pour l'alignement de deux éléments identiques dans un corps de connecteur. La fibre revêtue 71 s'ajuste dans un tube 16 placé dans l'axe de l'embout et de la lentille et comportant à l'avant un orifice de plus petit diamètre 73 guidant l'extrémité dénudée 72 de la fibre. Le tube peut comporter des moyens de réglage 37, 74 et être collé à la lentille après contrôle optique de la mise en place exacte de l'extrémité de la fibre au foyer de la lentille. Application aux systèmes de transmission par câbles optiques.Connector element for optical fiber, with beam widening by lens. According to the invention, the lens 32 is mounted in the anterior bore of a tip 31 comprising one or more reference surfaces used, in known manner, for the alignment of two identical elements in a connector body. The coated fiber 71 fits into a tube 16 placed in the axis of the tip and the lens and having at the front a smaller diameter orifice 73 guiding the stripped end 72 of the fiber. The tube may include adjustment means 37, 74 and be glued to the lens after optical control of the exact placement of the end of the fiber at the focal point of the lens. Application to optical cable transmission systems.
