Title
(EN) METHOD AND APPARATUS FOR SPLICING OPTICAL FIBERS
(FR) PROCEDE ET DISPOSITIF POUR L'EPISSURAGE DE FIBRES OPTIQUES
Abstract
(EN) A method and apparatus for aligning optical fibers for splicing utilizing a grooved holder (22) and positioning arms that engage the fiber ends (17, 18) and bring them precisely together in alignment for splicing. The grooves (24, 24', 26, 26', 28, 28') of the holder have a channel (27) extending therebetween. The precisely formed grooves (24, 24', 26, 26', 28, 28') provide alignement of the fibers via positioning arms (32, 32') having resilient pads (36, 36'). The resilient pads (36, 36') allow the positioning arms (32, 32') to frictionally engage the optical fibers (15, 16) and bring their respective ends (17, 18) into position for fusion splicing. The splicing method includes the steps of positioning fiber ends (17, 18) in aligned grooves (28, 28'), holding the fibers (15, 16) thereunder, engaging fiber ends (17, 18) with positioning arms (32, 32'), bringing the fiber ends (17, 18) together utilizing the positioning arms (32, 32'), and fusing the fiber ends (17, 18) employing a CO2 laser (60).
(FR) L'invention concerne un procédé et un dispositif pour l'alignement de fibres optiques à épissurer, avec système de maintien rainuré (22) et bras de positionnement prenant les extrémités de fibres (17, 18) aux fins d'alignement précis pour l'épissurage. Les rainures précises (24, 24', 26, 26', 28, 28'), qui sont séparées par un canal (27) s'étendant entre elles, assurent l'alignement des fibres par des bras de positionnement (32, 32') équipés de tampons souples (36, 36'), lesquels permettent aux bras (32, 32') de prendre les fibres (15, 16) par frottement et d'amener leurs extrémités respectives (17, 18) en position pour l'épissurage par fusion. Les étapes sont les suivantes: positionnement des extrémités de fibres (17, 18) dans les rainures alignées (28, 28'), maintien des fibres (15, 16), prise des extrémités de fibres (17, 18) par les bras de positionnement (32, 32'), réunion des extrémités de fibres (17, 18) par le biais des bras de positionnement (32, 32'), et fusion des extrémités de fibres (17, 18) par laser au CO2 (60).
