Title (EN) OPTICAL TRANSMISSION APPARATUS
(FR) APPAREIL DE TRANSMISSION OPTIQUE
(JA) 光伝送装置
Abstract:
(EN) Streamlining gain calibration of an optical transmission apparatus which uses Raman optical amplification is desired. This optical transmission device is provided with: a Raman amplification unit for supplying excitation light for performing Raman amplification for a transmission path; an optical monitor signal control unit which receives a monitoring light from a connection destination node of the transmission path; and a monitoring control unit which emits a standby signal, instructing stopping of supply of the excitation light, to the Raman amplification unit when the optical monitor signal control unit is not receiving the monitoring light, and executes calibration of gain of the Raman amplification unit when the standby signal is removed.
(FR) Selon la présente invention, la rationalisation d'étalonnage de gain d'un appareil de transmission optique qui utilise l'amplification optique Raman est souhaitée. L'équipement de transmission optique selon l'invention est pourvu : d'une unité d'amplification Raman qui sert à fournir une lumière d'excitation permettant d'effectuer une amplification Raman pour un trajet de transmission ; d'une unité de commande de signal de surveillance optique qui reçoit une lumière de surveillance à partir d'un nœud destinataire de connexion du trajet de transmission ; et d'une unité de commande de surveillance qui émet un signal d'attente, ordonnant l'arrêt de l'alimentation en lumière d'excitation, vers l'unité d'amplification Raman lorsque l'unité de commande de signal de surveillance optique ne reçoit pas la lumière de surveillance, et exécute l'étalonnage de gain de l'unité d'amplification Raman lorsque le signal d'attente est supprimé.
(JA)  ラマン光増幅を用いた光伝送装置の利得校正を効率化することが望まれる。光伝送装置は、伝送路にラマン増幅を行うための励起光の供給を行うラマン増幅ユニットと、伝送路の接続先ノードからの監視光を受信する光監視信号制御ユニットと、光監視信号制御ユニットが監視光を受信しないときラマン増幅ユニットに対して励起光の供給の停止を指令する待機信号を発信し、当該待機信号が解除されたときラマン増幅ユニットの利得の校正を実行する監視制御ユニットとを備える。
