Abstract

A cost-effective dense WDM-PON employing wavelength-locked Fabry-Perot lasers has been demonstrated. We have successfully demonstrated a dense WDM transmission of 4×622 Mb/s upstream signal with 50-GHz channel spacing over 30-km conventional single mode fiber. We have also investigated the heating noise characteristics of a wavelength-locked Fabry-Perot laser and showed the wavelength-locked Fabry-Perot laser suppresses the intensity noise of the incoherent light injected which enables a dense WDM transmission with a channels spacing of 50 GHz.

파장 고정된 Fabry-Perot 레이저를 사용하여 경제적인 고밀도 WDM-PON의 구현 가능성을 검증하였다. 중앙기지국에서 주입된 비간섭성광에 파장 고정된 Fabry-Perot 레이저를 이용하여 50 GHz 채널 간격의 파장분할 다중화된 4×622 Mb/s 상향신호를 30 km의 광섬유를 통해 성공적으로 전송하였다. 파장 고정된 Fabry-Perot 레이저 출력의 비팅 잡음 특성을 분석하여 Fabry-Perot 레이저가 주입되는 비간섭성 광의 강도 잡음을 억제함을 보였고, 이로 인해 50 GHz 채널 간격의 고밀도 WDM 전송이 가능함을 보였다.
