Abstract

　加入者側装置および局側装置で使用されている上り光信号および下り光信号の波長を変更することなく、両装置間の延伸化を可能とするポイント－マルチポイント光通信システムを得る。１台の局側装置１と複数ｎ台の加入者側装置４とを接続する光ネットワークを基本構成として、ｍ個の基本構成に対して１台の局側波長合分波器２２、１本の光ファイバ伝送路３０、および１台の加入者側波長合分波器１２による共有化を図ったポイント－マルチポイント光通信システムであって、１台の波長合分波器２２、１２とｍ個の波長変換装置２１、１１で構成される局側中継部２０および加入者側中継部１０を備え、局側装置１と局側中継部２０との間および加入者側装置４と加入者側中継部１０との間は、現状の波長の光信号を使用し、光ファイバ伝送路３０を介した波長合分波器１２、２２間は、延伸化可能な波長多重光信号を使用する。
