초록

본 논문에서는 SCM과 WDM방식의 아날로그 광 전송기술을 기반으로 IMT-2000 및 PCS 양 무선주파 수대역 전송에 사용 가능한 광 송수신기의 구조를 제안하고 이의 제작에 관련된 여러 파라미터들을 분석하였다. 특히 송신부의 고주파 신호와 LD사이의 임피던스 정합회로는 시뮬레이션을 통해 최적의 성능을 도출 하는 방법을 제안하였고, 또한 1.7GHz∼2.25GHz 대역에서 광 링크의 gain이 0dB일 때, 광 링크의 gain flatness 및 noise floor가 각각 ±1.5dB 및 -130dBm인 결과를 얻었다

In this paper, we proposed an fiber-optic transceivers based on the analog optical transmission techniques of incorporating the SCM (subcarrier multiplexing) and WDM (wavelength-division multiplexing ) method, which can be used to transmission of IMT-2000 and PCS wireless frequency band and analyzed overall those parameters related with fabrication. Especially in the impedance matching network between RF signal and LD, we proposed the method of deriving optimal performance using simulation techniques. In the frequency band of 1.7GHz∼2.25GHz, experimental data for the gain flatness and the noise floor of the optical link were also presented $\pm$1.5dB and -130dBm respectively when the link Rain was 0dB.
