Abstract

La présente invention concerne un procédé et un dispositif d'essai pour une alarme de réseau optique passif. Le procédé comprend les étapes consistant : à recevoir, par un terminal de ligne optique (OLT), une alarme de coupure de courant rapportée par une unité de réseau optique (ONU), et à comparer une différence entre un point temporel de génération de l'alarme de coupure de courant et un point temporel de réception de l'alarme de coupure de courant de l'OLT avec un seuil de tranche temporelle prédéfini ; si la différence satisfait le seuil de tranche temporelle prédéfini, alors à déterminer que l'ONU répond à une condition d'alarme de coupure de courant, et à compter un nombre d'ONU satisfaisant à la condition d'alarme de coupure de courant d'un port du réseau optique passif (PON) auquel l'ONU appartient ; et à comparer le nombre d'ONU avec un nombre total des ONU du port du PON, et si le résultat de comparaison satisfait une exigence prédéfinie, alors à déterminer que la zone dans laquelle le PON est situé subit une coupure de courant. La présente invention résout un problème de difficulté de traitement d'une alarme de coupure de courant d'ONU, et améliore la commodité d'exploitation et de maintenance du réseau pour un opérateur.
