Abstract:
(EN) When initial acquisition is completed, a signal processing unit (101e) controls an optical variable attenuator (10-4) and a control signal generation part (10-5), and causes the optical power of light for initial acquisition to be attenuated.
(FR) Lorsque l'acquisition initiale est achevée, une unité de traitement de signal (101e) commande un atténuateur variable optique (10-4) et une partie de génération de signal de commande (10-5), et provoque l'atténuation de la puissance optique de la lumière pour une acquisition initiale.
(JA) 信号処理部(101e)は、初期捕捉が完了すると、光可変アッテネータ(10-4)および制御信号生成部(10-5)を制御して初期捕捉用光の光パワーを減衰させる。
