A Wavelength Converter and Optical Switching Based WDM-TDM PON

随着无源光网络(Passive Optical Network,PON)技术的演进,大容量、高效率的PON是主要的发展趋势。PON的性能很大程度上取决于其架构,文章提出了一种基于波长变换和光交换的WDM-TDM PON(Wavelength-Time Division Multiplexing based PON)架构,该架构采用可调谐波长变换器以及光交换技术并在光线路终端(Optical Line Terminal,OLT)设计中实现,以实现大容量、高灵活性的WDM-TDM PON。文章研究了该架构在不同配置下的性能表现,并通过仿真实验进行了验证。仿真结果表明,文章所提出的基于波长变换的光交换结构可以满足大容量、灵活高效的通信要求。

With the evolution of passive optical network（PON） technology, PON with large capacity and high efficiency will be the development direction. Because the performance of PON largely depends on the network architecture, this paper proposes a tunable wavelength converter（TWC） and optical switching based WDMTDM PON architecture. Using the TWC and optical switching technologies, the optical line terminal（OLT） is designed and introduced into the proposed WDM-TDM PON. The performance is studied in simulation experiments with different configuration. Simulation results proved the proposed architecture can meet the requirement of communication with large capacity and high efficiency.
