Title (EN) THERMALLY ACTUATED FIBRE OPTIC CUTTING DEVICE
(FR) DISPOSITIF DE COUPE DE FIBRE OPTIQUE À ACTIONNEMENT THERMIQUE
Abstract:
(EN) A thermally actuated fibre optic cutting device including: a housing configured to receive an optical fibre element which passes through the housing from one side of the housing to another side of the housing in one continuous portion, wherein the optical fibre element is capable of transmitting a source of light along its length; one or more retaining portions for retaining the optical fibre element; and, a cutting element disposed within the housing for cutting the continuous portion of the optical fibre element in response to a change in temperature, the cutting element being moveable in a direction towards the continuous portion of the optical fibre element.
(FR) L'invention concerne un dispositif de coupe de fibre optique à actionnement thermique, comprenant : un boîtier conçu pour recevoir un élément de fibre optique qui passe à travers le boîtier depuis un côté du boîtier vers un autre côté du boîtier dans une portion continue, l'élément de fibre optique étant apte à transmettre une source de lumière le long de sa longueur ; une ou plusieurs portions de retenue destinées à retenir l'élément de fibre optique ; et un élément de coupe disposé à l'intérieur du boîtier pour couper la portion continue de l'élément de fibre optique en réponse à un changement de température, l'élément de coupe pouvant être déplacé dans une direction vers la portion continue de l'élément de fibre optique.
