Abstract

　本発明は、基準光を導通させるための光素子数を削減させた光ノード装置であり、ｐａ個の入力側波長合分波素子（１）と、スイッチモジュール（１０２）と、ｐｂ個の出力側波長合分波素子（３）と、基準光光源４と、をそなえ、入力側波長合分波素子（１）のそれぞれは、少なくとも２つの第１ポート（１ａ－１，１ａ－２）および第２ポート（１ｂ－１～１ｂ－ｎ）をそれぞれそなえるとともに、各入力側波長合分波素子１をなす前記第１ポートのうちの一（１ａ－１）は入力伝送路（１２１）に接続されるとともに、前記第１ポートのうちの他（１ａ－２）は基準光光源（４）に接続され、且つ各第２ポート（１ｂ－１～１ｂ－ｎ）はそれぞれスイッチモジュール（１０２）の入力端（１０２ａ）に接続される。
