Title (EN) OPTICAL FIBER AND METHOD FOR PRODUCING THE SAME
(FR) FIBRE OPTIQUE ET SON PROCÉDÉ DE FABRICATION

Abstract: front page image
(EN)Disclosed is an optical fiber comprising a core (1) having an outer diameter (D1) of not less than 8.2 &mgr;m but not more than 10.2 &mgr;m, a first cladding (2) so formed as to cover the core (1) and having an outer diameter (D2) of not less than 30 &mgr;m but not more than 45 &mgr;m, a second cladding (3) so formed as to cover the first cladding (2) and having a thickness (T) of not less than 7.4 &mgr;m, and a support layer (4) so formed as to cover the second cladding (3). The relative refractive index difference between the support layer (4) and the second cladding (3) with respect to the support layer (4) is not less than 0.5%.
(FR)L'invention porte sur une fibre optique comprenant une âme (1) ayant un diamètre externe (D1) de pas moins de 8,2 µm mais de pas plus de 10,2 µm, une première gaine (2) formée de façon à recouvrir l'âme (1) et ayant un diamètre externe (D2) de pas moins de 30 µm mais de pas plus de 45 µm, une seconde gaine (3) formée de façon à recouvrir la première gaine (2) et ayant une épaisseur (T) de pas moins de 7,4 µm, et une couche de support (4) formée de façon à recouvrir la seconde gaine (3). La différence d'indice de réfraction relatif entre la couche de support (4) et la seconde gaine (3) par rapport à la couche de support (4) est de pas moins de 0,5 %.
(JA) 外径(D)が8.2μm以上且つ10.2μm以下であるコア(1)と、コア(1)を覆うように設けられ、外径(D)が30μm以上且つ45μm以下である第1クラッド(2)と、第1クラッド(2)を覆うように設けられ、厚さ(T)が7.4μm以上である第2クラッド(3)と、第2クラッド(3)を覆うように設けられたサポート層(4)とを備え、サポート層(4)に対するサポート層(4)及び第2クラッド(3)の間の比屈折率差が0.5%以上である。
