| 摘 要： | 基于正交频分复用(orthogonal frequency-division multiplexing,OFDM)技术的无源光网络(passive opticalnetwork,PON)因其通信容量大、抗色散能力强等优点,已成为下一代基于PON接入网的解决方案之一.与此同时,40/100 Gbit/s以太网标准的制定也使100 Gbit/s光网络传输实用化成为可能.提出一种基于中心化梳状光源的全光OFDM-PON网络架构,为100 Gbit/s光接入网提供了高效的实现方法.该系统以梳状光谱发生器为中心化光源,实现了全光连续OFDM信号的产生以及低成本的上下行相干检测.最后,对系统进行模拟仿真,并对结果性能进行了分析。

| Abstract: | OFDM(orthogonal frequency-division multiplexing)-PON(passive optical network) is considered a promising solution for the next generation PON-based access networks.Meanwhile,the released 40/100 Gbit/s Ethernet standard allows 100 Gbit/s fiber transmission to be realized in the near future.We propose a novel OFDM-PON architecture based on all-optical waveform and flat frequency comb generation for 100 Gbit/s optical access.The flat frequency comb generation provides an effective and costless way to generate all-optical OFDM signals and implement coherent detection in both downstream and upstream.Simulation results show robust and outstanding performance of the proposed system. |
