| description | The present invention provides an optical transmission device and a WDM-PON system for the same which realizes an optical transceiver with a color free or a colorless method using DWDM to transmit high speed signals based on signal multiplexing. According to the present invention, a WDM-PON system for upward signals includes: an optical subscriber end device (ONU) comprising an optical transmitter which creates a low speed parallel optical signal by reverse multiplexing upward high speed signals, and a first optical multiplexing device multiplexing a parallel optical signal delivered from the optical transmitter; and a remote node (RN) comprising a second optical multiplexing device which multiplexes signals on the optical subscriber end device (ONU), and sends the signals to the optical route end device. Either the first or the second optical devices uses the circulation characteristics to make multiplexing channels, and the remaining other makes multiplexing channels made of at least one continuous channel.
신호 다중화 기술을 이용하여 고속의 신호를 전달함에 있어서, DWDM 방식을 이용하여 colorfree 방식 혹은 colorless 방식의 적용이 가능한 광트랜시버를 구현할 수 있는 광 전송장치 및 그를 위한 WDM-PON 시스템을 제공한다. 특히 본 발명의 상향신호를 위한 WDM-PON 시스템은, 상향 고속 신호를 역다중화하여 저속의 병렬 광신호를 형성하는 광 송신기와, 광 송신기로부터 전달된 병렬 광신호를 다중화하는 제1 광 다중화기를 포함하는 광가입자 종단장치(ONU)와; 광가입자 종단장치에서 전달된 신호를 다중화하여 광선로 종단장치로 전달하는 제2 광 다중화기를 포함하는 원격노드(RN)를 포함하되, 제1 및 제2 광 다중화기 중 어느 하나의 광 다중화기는 순환 특성을 이용하여 채널 단위로 다중화하고 다른 하나의 광 다중화기는 적어도 하나의 연속된 채널로 구성되는 채널군 단위로 다중화한다. |
