A fiber optic coupler (51) is automatically manufactured under the control of a programmable controller (79). A fiber feed device (26) sends fibers (16-17) through a tube (50). Fibers (16-17) are stored in the tube (50). Chucks (57- 58) pull in opposite directions to form a tapered coupling region. Epoxy dispensers dispense epoxy into uncollapsed ends of the coupling tube (12) bore. A UV light sources (70) cures the epoxy. The control of the apparatus by programmable controller eliminates operator inconsistencies and improves process reproducibility.

On fabrique automatiquement un coupleur à fibres optiques (51) sous la commande d'un dispositif de commande programmable (79). Un mécanisme d'alimentation en fibres (26) envoie des fibres (16-17) à travers un tube (50). Les fibres (16-17) sont rangées dans le tube (50). Des mandrins (57-58) exercent une traction dans des sens opposés, de manière à créer une zone de couplage rétrécie coniquement. Des distributeurs d'époxy injectent de l'époxy dans les extrémités non affaissées de l'alésage du tube de couplage (12). Une source d'ultraviolets (70) durcit l'époxy. Le dispositif de commande permet d'éliminer les risques provoqués par les distractions du technicien et d'améliorer la reproductibilité du processus.
