Title
(EN) MAGNETIC SEATING FOR FIBER OPTIC COMPONENT
(FR) SIÈGE MAGNÉTIQUE POUR COMPOSANT DE FIBRE OPTIQUE
Abstract
(EN)
An optical assembly includes an optical ferrule including a light redirecting member configured to receive light from an optical waveguide along a first direction and redirect the light along a different second direction, the redirected light exiting the optical ferrule at an exit location on a mating surface of the optical ferrule, and a cradle with a mating surface and configured to hold and align the optical ferrule to an optical component, wherein the mating surface of the optical ferrule and the mating surface of the cradle are held together by a magnetic attraction between opposing magnetic elements, wherein the optical ferrule and the cradle, but not the opposing elements, physically contact each other.
(FR)
Un ensemble optique comprend une ferrule optique comprenant un élément de redirection de lumière conçu pour recevoir de la lumière provenant d'un guide d'ondes optique le long d'une première direction et rediriger la lumière le long d'une seconde direction différente, la lumière redirigée sortant de la ferrule optique à un emplacement de sortie sur une surface d'accouplement de la ferrule optique, et un berceau ayant une surface d'accouplement et conçu pour maintenir et aligner la ferrule optique sur un composant optique, la surface d'accouplement de la ferrule optique et la surface d'accouplement du berceau étant maintenues ensemble par une attraction magnétique entre des éléments magnétiques opposés, la ferrule optique et le berceau, mais pas les éléments opposés, étant physiquement en contact l'un avec l'autre.
