PROCESS FOR MANUFACTURING A LIGHT GUIDE SHAPED BY FIBERGLASS
Abstract
Abstract Translated from French L'invention concerne un procédé pour fabriquer un guide de lumière formé par une fibre de verre. Selon ce procédé permettant d'accroître la résistance à la traction de la fibre, on dépose sur l'enveloppe d'une préforme de la fibre ou sur ladite-fibre au moins une couche protectrice en un verre dont le coefficient de dilatation thermique est plus faible que celui du verre adjacent de la fibre. Application notamment aux systèmes de transmission optique d'informations. The invention relates to a method for manufacturing a light guide formed by a glass fiber. According to this method making it possible to increase the tensile strength of the fiber, is deposited on the envelope of a preform of the fiber or on said fiber at least one protective layer made of a glass, the coefficient of thermal expansion of which is greater. weak than that of the adjacent glass of the fiber. Application in particular to optical information transmission systems.
