基于频谱分割的WDM-PON无色ONU仿真研究
首发时间:2014-02-21
摘要:波分复用无源光网络(WDM-PON)是未来接入网的发展方向,而基于宽光源频谱分割的无色ONU技术又是构建WDM-PON的较理想方案。本文用LED作为宽光源进行频谱分割以用作上行光源,设计了4路的上行方案,并用Optisystem软件进行了仿真,在仿真中,当调制速率不高于230Mbit/s时,可以比较好的质量传输20km。

Research and Simulation of the WDM-PON colorless ONU based on spectral slicing
Abstract:Waveleng division multiplexed passive optical network(WDM-PON) is the development direction of future access network,and the colorless ONU technology based on wide light source spectrum slicing is the ideal solution of WDM-PON.In this paper LED as wide source spectral slicing is userd for uplink.And had designed a scheme of four uplik.Optisystem software has carried on the simulation, in the simulation, when the modulation rate is't higher than 230 Mbit/s system could transmit 20km for good quality.
Keywords: WDM-PON LED spectral slicing Optisystem
