Abstract

Dispositifs et procédés servant à permuter la transmission de lumière d'une fibre optique (45) à une autre (460). Une fibre orientable (430) possède une extrémité (432) placée dans une capsule (404, 406), de la même manière qu'une ou plusieurs fibres coopérantes (450, 440). La fibre orientable (430) se trouve initialement en position de repos et introduit la lumière dans une des fibres coopérantes (450) depuis cette position. L'extrémité (432) de la fibre orientable (430) comporte un induit (435) se déplaçant sous l'effet de l'application de champs magnétiques. Un champ magnétique est ensuite généré de façon sélective et une paire de pièces polaires (420) le transfère jusqu'à un emplacement (424) situé à l'intérieur (408) de la capsule, à proximité de l'induit (435). De ce fait, l'extrémité (432) de la fibre orientable (430) est déplacée vers une autre position depuis laquelle elle introduit la lumière dans l'autre fibre coopérante (440).
