摘　　要：文章提出了一种新型的基于正交频移键控(FSK)/幅移键控(ASK)再调制的波分复用-无源光网络(WDM-PON)结构,在下行方向,采用一种新型的基于相位-强度调制转换的FSK调制技术,实现了40 GHz的高速FSK信号;在上行方向,直接将10 GHz的ASK信号调制到FSK信号上,实现正交调制。文章研究了整个系统的性能,仿真结果显示,这种WDM-PON结构能满足接入网的传输要求,为未来的高速接入网提供了一种选择。A novel WDM-PON structure based on orthogonal FSK/ASK re-modulation scheme is presented in this paper.In the downstream direction,a FSK modulation technology based on phase-to-intensity modulation conversion is adopted to generate 40 Gbit/s FSK signals,while in the upstream direction,10 Gbit/s ASK signals are directly modulated onto the FSK signals to achieve orthogonal modulation format.The performances of the entire system are studied and simulation results show that this structure can satisfy the requirements for access network transmission and provides an option for the future high-rate access networks.
