本論文提出新型分波多工被動光網路架構,藉由增加額外的被動元件,可以使分波多工被動光網路操作在兩個波段,能夠有效降低雷利散射及後向反射的影響,並且提升分波多工被動光網路的容量。本論文中,我們使用被動元件分開上下行傳送訊號,不同於傳統的分波多工被動光網路架構只使用單一光纖傳送上下行訊號,故可以減少雷利散射的干擾。考慮在光網路單元中使用於再次調變上行訊號用的反射式半導體光放大器元件,工作在不同條件時,由理論分析探討包含來自上行訊號本身的雷利散射和後向反射的干擾訊號對上行訊號的影響。實驗結果中,我們同時傳送下行10 Gb/s和上行1.25 Gb/s速率的訊號,可包含C和L的波段,傳輸距離為25公里,光功率償付值皆在1.5 dB附近。另外我們還實際量測到雷利散射和考慮線路中存在不同後向功率時,下行訊號不會遭受到雷利散射和後向反射的干擾,還可以提升上行訊號對額外後向功率的容忍度到-28 dB都沒有額外的光功率償付值。
In this thesis, we propose a novel WDM-PON architecture to increase the system capacity by using C- and L- wavelength bands and to suppress the Rayleigh scattering effect by only adding low-cost filtering components. In conventional WDM-PON systems, it suffers from serious Rayleigh scattering problem since the downstream and upstream signals are transmitted in single fiber. In our novel system, DFB lasers operating at C- or L- band and RSOAs are used as transmitters for OLTs and remodulators for ONUs, respectively. We use C/L-band filters to separate downstream (C- or L-band) and upstream (L- or C-band) signals and avoid the Rayleigh scattering interference between the wavelength bands. We also investigate the impact of Rayleigh scattering and back-reflection on upstream signal quality. We successfully demonstrated 10 Gb/s and 1.25 Gb/s data rates for the downstream and upstream transmission, respectively, for both C- and L- wavelength bands in this novel system. After 25 km of transmission all channels only suffer from 1.5 dB of power penalty. Besides, we measure the performance of upstream and downstream signals in the conditions of different back-reflection power levels. Experimental results proved that the back-reflection problem can be neglected for the downstream signals. The impact of back-reflection on upstream signals is also reduced and no power penalty can be achieved for the upstream signals if back-reflection power level is less than -28 dB.
