摘 要:針對當前光纖接入網因基于時分復用技術而面臨的“瓶頸”問題,提出了將波分復用無源光網絡(WDM-PON)技術引入到接入網,設計了8通道下行傳輸方案,用Optisystem進行了仿真。通過對眼圖的分析,驗證了該系統的可靠性。最后得出結論:8通道的WDM-PON可使接入網的下行速率由現在的2.5GBit/s提高到80GBit/s,可有效解決接入網下行傳輸的“瓶頸”問題。

Abstract:In view of the "bottleneck" problem of current access network based on time division multiplexing technology , the wavelength division multiplexing passive optical network (WDM-PON) technology was introduced to the access network, a project of 8 channel downlink signal transmission scheme was designed and simulated by Optisystem. Through the analysis of eye diagram, verified the reliability of the system. At last shows that, WDM-PON can make the downlink rate from 2.5GBit/s to 80GBit/s, which can effectively solve the problem of access network downlink transmission "bottleneck" problem.
