Abstract

In this paper, we report that the differences between RF power levels can be improved in wavelength division multiplexing - radio over fiber (WDM-RoF) system by using a photonic crystal fiber. In a WDM-RoF system, each WDM channel experiences different received RF power level fluctuation in remote node (RN) because of wavelength-dependent dispersion. Since each WDM channel experiences different power fluctuation, the RF power fluctuation acts as a design constraint in viewpoint of network design. We designed a photonic crystal fiber to improve the effect of wavelength- dependent dispersion on RF power fluctuation. Also, we analyzed the wavelength-dependent difference of inter-channel RF power fluctuations.

파장분할다중화-무선광통신(WDM-RoF) 시스템에서 광결정 광섬유를 이용하여 채널 간 고주파신호들의 전력변화의 편차를 분석하여 이들을 조절할 수 있음을 확인하였다. WDM-RoF 시스템의 경우, 원격노드에서의 고주파 신호 특성은 파장 의존성을 갖는 단일모드 광섬유의 분산 특성으로 인해 전송거리 증가에 대한 고주파신호 수신 전력 변화가 채널의 파장에 따른 편차를 나타내게 되며, 이는 전체 시스템 설계시 전송거리에 대한 제한 요소로 작용할 수 있다. 광결정 광섬유의 분산보상 특성을 이용하여 WDM 채널에 따른 고주파 전송특성을 개선할 수 있는 광결정 광섬유를 설계하고, 이를 통해 채널간 고주파 전송특성의 편차를 분석하였다.
