| 摘 要： | 文章首次提出了基于单边带光正交频分复用（OOFDM）的TDM/WDM-PON方案并建立了一个通道的系统模型。下行采用80Gbit/s的单边带OFDM信号,节约WDM通道带宽资源,减小色散的影响,OLT调整各ONU的子载波个数即可实现动态带宽分配。上行采用20Gbit/s的NRZ信号。利用半导体光放大器（SOA）的增益饱和特性实现了ONU的无色管理。对系统模型进行了仿真,并对结果进行了分析。

| Abstract: | A TDM/WDM-PON scheme based on single side band（SSB） OOFDM（optical orthogonal frequency division multiple） is proposed and a system model of one channel is made.Downstream SSB OFDM signal at 80Gbit/s is used to save the bandwidth resource of a WDM channel and limit the influence of dispersion.Dynamic bandwidth allocation can be achieved by adjusting the subcarrier number for each ONU.Upstream NRZ signal is 20Gbit/s and colorless ONU is realized by the gain saturation of semiconductor optical amplifier（SOA）.This system model is simulated and the simulation results are analyzed. |
