Abstract

　異なるビットレートが混在する光信号のＯＡＤＭ制御時に、効率よく分散補償を行う。 　挿入制御部（１２）は、挿入すべき光信号である挿入光信号のビットレートがｋ種類ある場合には、Ｎ入力ポートの内、ｋ（＜Ｎ）個のｋ入力ポートと接続して、ｋ入力ポートへ挿入光信号を送信して挿入制御を行う。分岐制御部（１３）は、Ｍ出力ポートの内、ｍ（＜Ｍ）個のｍ出力ポートと接続して、ｍ出力ポートから送信された光信号の分岐制御を行う。Ｎ×Ｍ波長選択スイッチ（１１）のｋ入力ポートと、挿入制御部（１２）と、を接続するｋ個の方路（Ｌ１～Ｌｋ）それぞれには、ビットレート毎に対応した波長分散を補償するための分散補償を設定し、挿入制御部（１２）は、挿入光信号の分散補償を行う方路を選択して、選択した方路を介して、挿入光信号をＮ×Ｍ波長選択スイッチ（１１）へ送信する。
