高速正交分頻多工被動光網路系統透過非線性失真補償技術

Abstract

隨著數位資訊快速的增加，許多數據被大量的創造或複製出來透過不同的智慧型裝置。近年來網路流量的模式將會有所改變，其中一個就是區域型網路快速的增加，而被動式光網路也成為光纖到家的主要科技。為了達到國際標準制訂組織(FSAN)制定的下世代網路標準(NG-PON2)並減少成本，長距離被動式光網路系統將在近年來成為一個解決辦法。 另一方面，隨著矽晶體的方展帶來了數位訊號處理(DSP)迅速的發展，正交分頻多工(OFDM)成為一個具有潛力的科技並且將被應用在存取式網路(access networks)。同時，隨著數位訊號處理(DSP)的發展，我們將研究非線性失真補償技術。因此，一個高速正交分頻多工長距離被動式光網路系統將透過實驗被示範出來。

With the growth of digital information, lots of data will be created from smart device such as smart TV, mobile phone, and smart car etc. The communication traffic patterns will change in the near future. One of the changes is the increasing of metro traffic. Besides, passive optical network (PON) become the major fiber-to-the home (FFTH) technology. In order to meet the requirement of next-generation PON (NGPON2) by Full Service Access Network (FSAN) and reduce the cost of PON network, the long-reach PON (LR-PON) will appear in the near future. Moreover, the digital signal processing (DSP) technology develops rapidly with the growth of silicon. OFDM will be a high potential solution for access networks. Meanwhile, we study on the nonlinear distortion compensation techniques based on the DSP technology. Thus, a high-speed OFDM LR-PON system will be demonstrated.
