Description

測定用機器１のランチコネクタ９から出射される測定光ＤＬを用いて挿入損失Ｌβを実際に測定した。光ファイバ７には、長さ１ｍ、コア径／クラッド径＝２００μｍ／２３０μｍ、開口数（ＮＡ：Numerical Aperture）＝０．３７のハードポリマークラッドファイバを用いた。また、光源３からは、ＮＡを０．０５〜０．６０の範囲で変動させた光を光ファイバ７に入射させた。この入射光としては、ガウシアンビームを用いることができる。一方で、同じ仕様でかつ長さが２ｋｍの光ファイバを用いて定常励振モードを作り出して、当該光ファイバ７の挿入損失Ｌαを測定した。その結果を表１に示し、さらに表１の結果を直線近似にて解析した結果を図３に示す。
