全光正交频分复用双偏振四相相移键控高速传输系统 AO-OFDM DP-QPSK high-rate transmission system

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100 Gbit/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2.7 bit/s/Hz 的400 Gbit/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3 564 km·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70 ps/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400 Gbit/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.
