Title (EN) OPTICAL FIBER
(FR) FIBRE OPTIQUE
(JA) 光ファイバ
Abstract:
(EN) An optical fiber of an embodiment of the present invention comprises, as a structure appropriate for long-distance and high-capacity transmission, the following: a core; cladding having an outer diameter of 80-130μm; a primary coating; and a secondary coating having elasticity which is higher than that of the first coating and having an outer diameter of no more than 210μm. The optical fiber having this structure has: a MFD of at least 10μm at a wavelength of 1550nm; a cable cut-off wavelength of longer than 1260nm; and a micro-bend loss of no more than 0.6dB/km at a wavelength of 1550nm.
(FR) Un mode de réalisation de la présente invention concerne une fibre optique comprenant, en tant que structure appropriée pour une transmission sur longue distance et à haute capacité, les éléments suivants : une âme ; une gaine ayant un diamètre extérieur de 80 à 130 µm ; un revêtement primaire ; et un revêtement secondaire ayant une élasticité supérieure à celle du premier revêtement et ayant un diamètre extérieur inférieur ou égal à 210 µm. La fibre optique qui possède cette structure présente : un MFD d'au moins 10 µm à une longueur d'onde de 1550 nm ; une longueur d'onde de coupure de câble supérieure à 1260 nm ; et un affaiblissement de microcourbure maximal de 0,6 dB/km à une longueur d'onde de 1550 nm.
(JA) 本実施形態に係る光ファイバは、長距離かつ大容量の伝送に適した構造として、コア、80μm以上130μm以下の外径を有するクラッド、一次被覆、および一次被覆より高い弾性と210μm以下の外径を有する二次被覆を備える。係る構造を有する当該光ファイバは、波長1550nmにおいて10μm以上のMFDと、1260nmより長いケーブルカットオフ波長と、波長1550nmにおいて0.6dB/km以下のマイクロベンドロスを有する。
