本論文研究具有故障防護功能的分波多工通訊系統於下世代接取網路,並且採用樹狀分波多工光纖網路的架構,為驗證此系統的通訊效能,在點對點與經由25km光纖傳輸後的情況下,分別分析偽隨機位元序列之位元錯誤率與正交振幅調變訊號之誤差向量幅度之效能,根據實驗的結果顯示,偽隨機位元序列與正交振幅調變訊號都符合通訊需求,研究成果有助於提升下世代接取網路的覆蓋範圍與通訊效能。
This dissertation studies the failure protection function of the wavelength division multiplexing (WDM) communication system for the next generation access network, the proposed fault protection system adopts the tree-shaped WDM fiber-optic network architecture, to verify the communication performance of this system after point-to-point and 25km optical fiber transmission, in terms of the bit error rate(BER) of the pseudo-random bit sequence and the error vector magnitude(EVM) of the quadrature amplitude modulation signal, respectively. According to the experimental results, both the pseudo-random bit sequence and the quadrature amplitude modulation signal are the consistent communication requirements, and improves the coverage and communication efficiency of the next-generation access network.
