Title (EN) LONG LIFETIME OPTICAL FIBER AND METHOD
(FR) FIBRE OPTIQUE À GRANDE DURÉE DE VIE ET PROCÉDÉ
Abstract:
(EN) A fiber optic construction is described combining low OH (preferably < 1 ppm) materials for use in the core and cladding elements with controlled D0/d ratios to provide extended life expectancy fiber optics for use in high-temperature environments.
(FR) L'invention concerne une structure de fibre optique combinant des matériaux à faible teneur en OH (de préférence < 1 ppm) pouvant être utilisés dans les éléments de coeur et de gaine avec des rapports D0/d régulés permettant d'assurer une espérance de vie prolongée de fibres optiques destinées à être utilisées dans des environnements à haute température.
