Title: 光導波装置
IPC: G02B1/04
Filed: 2000-03-30
Abstract: (57)【要約】
自動車産業が隆盛してきて、プラスチック光ファイバが多く必要とされ、これらのファイバの保護外装体４はポリアミド材料からできている。従来のポリアミド材料では、クラッデング体３を形成するフッ化ポリマーに対する粘着力が不足するため、プラスチック光ファイバ(２,３)のクラッデング体３と保護外装体４との間で、温度変化にともなって移動やズレを生じる虞があった。これはピストニングといわれる現象であり、これを抑制するために、光ファイバ(２,３)のコネクターやホルダーは、大変大きな力で保護外装体４と光ファイバ(２,３)とを押さえつける必要があり、このことが信号の減衰をまねいてしまうという問題があった。本発明では、改良されたポリアミド材料を用いて、フッ化ポリマーからなるプラスチック光ファイバ(２,３)におけるクラッデング体３と保護外装体４間の粘着性を大いに改良して進展させたものである。ここで、保護外装体４の材料としては特に改良されたポリアミドＴ(ＰＡ１２)を用い、このカルボキシル末端基の最大濃度は１５μｅｑ／ｇで、かつアミノ末端基の濃度は５０〜３００μｅｑ／ｇの範囲として装置構成すると、優れた光導波装置が得られる。
