摘要: 隨著資訊大爆炸的時代來臨,人們對社群網站及軟體的依賴,對資訊傳輸流量的要求也日漸升高,被動光網路是一個有效解決需求量的極佳辦法。國際組織FSAN制定了命名為NGPON2的下世代被動式光網路,光纖傳輸距離為20公里至100公里,並提供40Gb/s網路傳輸量,支援每個用戶1Gbps的使用流量。 在本篇討論中,我們使用正交多頻分波多工的系統傳輸,將系統分成八個通道,使用自相位調變(SPM)解決RF Power Fading,並用非線性失真補償技術提高傳輸速率。在整個傳輸過程中沒有使用光放大器並且重新使用了10GHz的電吸收調變器(EAM)和感光二極體(PIN),在經過60公里的傳輸之後總傳輸量可達400Gbps,每個通道的損耗預算為24-dB,支援64位用戶超過6Gbps的使用流量。
Since the era of information explosion is coming and public’s reliance of social media, the needs of data transmission is getting larger nowadays. Passive optical network (PON) is a promising way to achieve the requirement. In the standard of next-generation PON (NGPON2) by Full Service Access Network, the fiber distance is 20-km to 1000-km, and provides 40-Gbps network transmission capacity to support 1-Gbps data rate per optical network unit (ONU). In this paper, we employ WDM-OFDM PON system to the eight channels. We solve the RF power fading by self-phase modulation (SPM) effect and improve the data rate by the non-linear distortion compensation technology. There are not any inline amplifier and pre-amplifier through the entire system, and we reuse the 10-GHz EAM and PIN, the data rate after 60-km transmission can reach 400Gbps data rate, the loss budget is 24-dB per channel. Therefore it can support 64 ONUs with >6-Gbps capacity.
