摘要
在无色化波分复用无源光网络(WDM-PONs)中,基于反射半导体光放大器(RSOA)的单光纤WDM-PON倍受青睐,但沿光纤传输时由于瑞利散射的影响,性能有较大下降,因此主要讨论和研究在WDM-PON中如何消除瑞利散射的影响。首先介绍了无色化的WDM-PON,描述了瑞利散射的产生机理,然后总结当前国内外研究者消除瑞利散射的方法,并具体阐述其中的3个方案。最后用optisystem对新型WDM-PON结构中瑞利散射的消除方案进行仿真。
single-fiber WDM-PONs based on reflective semiconductor optical amplifier(RSOA)has become widely accepted In the schemes of colorless WDM-PONs,but its performance have larger decline because of the Rayleigh scatting efficiency when along the optical fiber teansmission.The paper discusses how to eliminate the effects of Rayleigh scattering in WDM-PON.First,the colorless WDM-PON is introduced,and a description of the mechanism of the Rayleigh scattering is given.The paper then makes a review of methods of eliminating Rayleigh scattering effect,and describes three schemes of them in details.Finally,software Optisystem is used to demonstrate how to emulate the Rayleigh scattering effect in a new ring structure of WDM-PON.
