Abstract: front page image
(EN) An optical fiber (1) provided with a depressed layer (112) interposed between a core (111) and a cladding layer (113), wherein the effective core cross-section area Aeff is set to 100 μm2 to 129 μm2, the radius r1 of the core (111) is set to 5.2-7.4 μm, the refractive index volume Vcore of the core (111) is set to 8.5 %μm2 to 16.5 %μm2, and the refractive index volume Vdep of the depressed layer (112) is set to -40 %μm2 to below 0 μm2.
(FR) L'invention concerne une fibre optique (1) qui comporte une couche enfoncée (112) interposée entre un noyau (111) et une couche de gaine (113), la surface effective de section transversale de noyau Aeff étant réglée à 100 μm2 à 129 μm2, le rayon r1 du noyau (111) étant réglé à 5,2-7,4 µm, le volume d'indice de réfraction Vnoyau du noyau (111) étant réglé à 8.5 %μm2 à 16.5 %μm2, et le volume d'indice de réfraction Venfoncé de la couche enfoncée (112) étant réglé à -40 %μm2 à au-dessous de 0 μm2.
(JA) コア(111)とクラッド層(113)との間に介在するディプレスド層(112)を備えた光ファイバ(1)において、実効コア断面積Aeffを100μm以上、129μm以下とし、コア(111)の半径r1を5.2μm以上、7.4μm以下とし、コア(111)の屈折率体積Vcoreを8.5%μm以上、16.5%μm以下とし、ディプレスド層(112)の屈折率体積Vdepを-40%μm以上、0μm未満とする。
