Abstract

L'invention a trait à un élément optique destiné à être incorporé à un dispositif de transmission optique. Ledit élément comporte une fibre optique 1, éventuellement munie d'une mince couche protectrice appliquée étroitement autour de la fibre, et en outre munie d'un revêtement 2 de section transversale sensiblement circulaire appliqué coaxialement étroitement autour de la fibre. Le revêtement 2 présente une adhérence vis-à-vis de la fibre optique éventuellement munie d'une couche protectrice telle qu'une tendance à la contraction du revêtement conférée durant ou après l'application de celui-ci exerce sur toute la longueur de la fibre une compression axiale telle qu'elle provoque un raccourcissement réel de la fibre et une augmentation correspondante de l'allongement à la rupture de celle-ci. Application : notamment aux télécâbles.
