…Since then, research and development into optical fiber has progressed explosively, and it has become possible to obtain fibers with extremely low losses, such as 0.2 dB/km. Optical fibers are broadly divided into glass fibers and plastic fibers based on the materials they are made from, and glass fibers are further divided into silica-based glass fibers and multi-component glass fibers. Silica-based glass fibers, which have low losses, are mainly used for communications, while plastic fibers are often used for transmitting optical energy in lighting devices and decorative purposes. … *Some of the terminology that mentions "glass fiber" is listed below.

…以来,光ファイバーに関する研究開発は爆発的に進められ,0.2dB/kmといった極低損失なファイバーも得られるようになった。光ファイバーは構成材料の面からガラスファイバーとプラスチックファイバーに大別され,さらにガラスファイバーは石英系ガラスファイバーと多成分系ガラスファイバーに分類される。通信用としては損失の少ない石英系ガラスファイバーがおもに使われており,プラスチックファイバーは照明装置用や装飾用として光エネルギー伝送によく使われている。… ※「ガラスファイバー」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
