摘要

AO-OFDM（全光正交频分复用）技术是利用光处理方式实现多载波和OIDFT（光离散傅里叶逆变换）/ODFT（光离散傅里叶变换）

其优势在于能提高处理速率、降低能量消耗。文章结合AO-OFDM技术和单通道100Gbit/s DP-QPSK（双偏振四相相移键控）高阶调制技术

实现了谱效率达到2.7bit/s/Hz的400Gbit/s高速传输系统

在色散完全补偿情况下

实现了最大SEDP（谱效率-距离积重）为3 564km.bit/s/Hz的传输

并利用插入12.5%循环前缀的方式

使得系统色散容限达到70ps/nm。实验结果表明

采用AO-OFDM技术的系统具有优良的传输性能

可以作为下一代400Gbit/s高速传输系统实际应用的方案。

Abstract

The All-Optical Orthogonal Frequency-Division Multiplexing（AO-OFDM） technology is used to implement multicarriers and Optical Inverse Discrete Fourier Transform（OIDFT）/Optical Discrete Fourier Transform（ODFT） by way of optical processing

which has the advantages of improving the processing rate and reducing power consumption.By using the AO-OFDM technology in combination with the single-channel 100 Gbit/s DP-QPSK high-order modulation technology

we can realize a 400 Gbit/s transmission system with a spectral efficiency of 2.7 bit/s/Hz and when the chromatic dispersion is completely compensated

we achieve a transmission with the maximum Spectral Efficiency-Distance Product（SEDP） of 3 564 km·bit/s/Hz.With 12.5% Optical Cyclic Prefixes（OCPs） inserted

the system dispersion tolerance reaches 70 ps/nm.The experimental results show that using the AO-OFDM technology

the system has better performances and can be used as a practical application scheme for next generation 400 Gbit/s transmission systems.
