Abstract

본 발명은 광 가입자망에 사용되는 광 FDM(Optical Frequency Division Multiplexing)시스템을 대상으로 송신부로 부터 등주파수(광캐리어)간격으로 정렬되어 들어오는 채널들을 수신부에서 동기적 방법으로 분리 추출할 수 있는 광 FDM 시스템에 있어서 동기 방식에 의한 채널 분리/추출 장치에 관한 것으로, 들어온 채널을 정해진 채널 슬롯에 재정렬한 후 수신된 광동기신호에 맞춰 고정 광필터로서 간단히 채널 분리/추출함으로써 시스템 구성을 단순화시킴과 동시에 동기망에서의 운용을 가능하게 해준다.The present invention is an optical FDM system for extracting and extracting channels, which are arranged at equal frequency (optical carrier) intervals from a transmitter, for an optical optical division multiplexing (FDM) system used in an optical subscriber network, in a synchronous manner. The present invention relates to a channel separation / extraction apparatus using a synchronous method, which simplifies system configuration by simplifying system configuration by rearranging an incoming channel to a predetermined channel slot and simply separating / extracting the channel as a fixed optical filter in accordance with a received optical synchronization signal. Enable operation in the network.
