Abstract
受信信号光の入力レベルを常に適正範囲に安定化させるため、本発明の光送受信モジュールは、光を出力する光出力部(1a)と、入力される光を受光し前記受光した光強度に応じた強度の電気信号を出力する受光部(1b′)と、光出力部(1a)から出力された光について可変減衰制御する第1可変減衰制御部(12)と、受光部(1b′)に入力される光について可変減衰制御する第2可変減衰制御部(13)と、第1可変減衰制御部(12)からの光について、光送信用方路か、又は前記光送信用方路と異なる他方路のいずれか一方を通じて選択的に切り替えて出力する第1スイッチ(3)と、外部からの光か又は第1スイッチ(3)の前記他方路からの光のいずれか一方を選択的に切り替えて第2可変減衰制御部(13)に出力する第2スイッチ(7)と、をそなえる。
