Abstract

　波長分散測定器を用いずにデジタルフィルタのタップ係数を設定可能で且つタップ係数設定時間の短いコヒーレント光受信機を提案する。 　局部発振光ＥＬＯと受信信号光ＥＳとを合波し、光位相が互いに異なる二組の光を出力する合波部１と、該合波部の出力光を差動光電変換する光電変換部３～６と、該光電変換部から出力される各電気信号をデジタル信号に変換するＡＤ変換部７，８と、該ＡＤ変換部によるデジタル信号をデジタルフィルタ１２で演算処理して波長分散補償を行った後に、受信信号光に含まれるデータの受信処理を実行するデジタル信号処理部１０～１５と、前記光電変換部から出力される電気信号の所定の帯域における強度成分をモニタするモニタ部２０と、該モニタ部によるモニタ結果に従ってデジタルフィルタ１２のタップ係数を決定するタップ係数調整部２１と、を含んだ構成とする。
