摘　　要：网络的升级带来对带宽和频谱利用率更严峻的要求。文中主要探讨了一种基于可调谐光纤光栅OADM的两级TDM/WDM混合组网方案:在原OLT和ONU之间插入Sub-OLT,采用10 G/1 G混合速率组网。并插入可调谐FBG的OADM,以实现波长的灵活上传下载。Opti System的建模仿真结果表明,通过插入可调谐光纤光栅的OADM和Sub-OLT构成的两级结构,可以在兼容10 G EPON系统的前提下增大传输带宽,增加频谱灵活度。The demand for upgrade of network brings with it concerns over bandwidth and spectral efficiency. This paper discusses a TDM / WDM hybrid network solutions based on OADM of tunable fiber grating： inserting the Sub-OLT between the original OLT and ONU,using 10 G /1G mixing rate networking,and inserting the OADM of tunable FBG to achieve the flexible wavelength upload and download. Simulation results of Opti System modeling show that the two-stage structure by inserting the OADM of tunable fiber gratings and Sub-OLT can increase the bandwidth and the spectrum flexibility in compatible 10 G EPON systems.
