Abstract
Description
本発明の実施の形態に係る光ファイバテープ心線の製造方法の一例としては、複数本の光ファイバ心線10a~10dを並列に進行させて、所定の位置に紫外線硬化樹脂を塗布する。その後、紫外線を照射して紫外線硬化樹脂を硬化させて、隣接する光ファイバ心線10a~10dを間欠的に固定する連結部22a~22f及び光ファイバ心線10a~10dを覆う被覆部21a~21dを形成する。
第1の実施例として、直径250μmの着色光ファイバ心線を用いて、テープ化材の被覆部に着色光ファイバ心線の着色層の一部を露出するように開口部が設けられた4心の間欠固定型の光ファイバテープ心線(試料A)を作製した。更に、比較例として、テープ化材の被覆部が着色光ファイバ心線の着色層を露出することなく全周を覆う4心の間欠固定型の光ファイバテープ心線(試料B)を作製した。
第1の実施例と同様の研磨紙にアルコールを塗布して、第1の実施例と同様の試料A,Bについて、単心分離後のテープ化材除去を行い、テープ化材を除去できるまでにしごいた回数を測定した。
第1の実施例と同様の試料Aについて、被覆部の開口部の露出角度(断面露出角)を90°、15°と変えたものを作製し、第1の実施例と同様の試料B(断面露出角が0°)と共に、単心分離後にテープ材の被覆除去回数を測定した。この結果、図7に示すように、断面露出角が広いほど、テープ材の被覆除去回数が減少することが分かる。特に、露出角度が15°以上であれば、テープ材の被覆除去回数が激減することが分かる。
上記のように、本発明は実施の形態によって記載したが、この開示の一部をなす論述及び図面はこの発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなろう。
