Title
(KO) 링형 광 네트워크 감시 방법 및 그 장치
Abstract
(KO)
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.
