Zusammenfassung:Disclosed is a method and device for monitoring a ring-type optical network. According to an aspect of the present embodiment, a method for monitoring a ring-type optical network by an in-house device comprises the steps of: generating a monitoring signal; converting the generated monitoring signal into an optical signal, and transmitting the converted optical signal; receiving the optical signal and converting the received optical signal into an electrical signal; and analyzing the converted electrical signal, wherein the monitoring signal includes a bit error rate (BER) code, a forward error correction (FEC) code, and a time code, and an ID. L'invention concerne un procédé et un dispositif de surveillance de réseau optique de type annulaire. Selon un aspect du présent mode de réalisation, un procédé de surveillance d'un réseau optique de type annulaire par un dispositif interne comprend les étapes consistant : à générer un signal de surveillance ; à convertir le signal de surveillance généré en un signal optique et à transmettre le signal optique converti ; à recevoir le signal optique et à convertir le signal optique reçu en un signal électrique ; à analyser le signal électrique converti, le signal de surveillance comprenant un code de taux d'erreur sur les bits (BER), un code de correction d'erreur sans voie de retour (FEC), un code temporel et un ID. 링형 광 네트워크를 감시하는 방법 및 그 장치를 개시한다. 본 실시예의 일 측면에 의하면, 국사내 장치가 링형 광 네트워크를 감시하는 방법은, 감시용 신호를 생성하는 과정, 상기 생성된 감시용 신호를 광 신호로 변환하여 송신하는 과정, 광 신호를 수신하여 전기적 신호로 변환하는 과정, 및 상기 변환된 전기적 신호를 분석하는 과정을 포함하고, 상기 감시용 신호는 BER(Bit Error Rate) 코드, FEC(Forward Error Correction) 코드, Time 코드, 및 ID를 포함한다.
