Title (EN) OPTICAL FIBER AND METHOD FOR MANUFACTURING OPTICAL FIBER
(FR) FIBRE OPTIQUE ET PROCÉDÉ DE PRODUCTION DE FIBRE OPTIQUE
(JA) 光ファイバ及び光ファイバの製造方法
Abstract:
(EN) This optical fiber is provided with a glass fiber (13), a primary resin layer (14) for covering the periphery of the glass fiber (13), and a secondary resin layer (15) for covering the periphery of the primary resin layer (14). The primary resin layer (14) has a pH that is greater than the pH of the secondary resin layer (15).
(FR) Cette fibre optique est pourvue d'une fibre de verre (13), d'une couche de résine primaire (14) pour recouvrir la périphérie de la fibre de verre (13), et d'une couche de résine secondaire (15) pour recouvrir la périphérie de la couche de résine primaire (14). La couche de résine primaire (14) a un pH qui est supérieur au pH de la couche de résine secondaire (15).
(JA) 光ファイバは、ガラスファイバ(13)と、ガラスファイバ(13)の外周を被覆するプライマリ樹脂層(14)と、プライマリ樹脂層(14)の外周を被覆するセカンダリ樹脂層(15)と、を備え、プライマリ樹脂層(14)のpHが、セカンダリ樹脂層(15)のpHよりも大きい。
