Abstract

An all-optical sampling OFDM scheme using PolMux-DQPSK format with single source is proposed and experimentally demonstrated. 5 × 200 Gb/s AOS-OFDM signal with spectral efficiency of 3.07 bit/s/Hz is successfully transmitted over an 80 km SMF link with real-time detection by optical Fourier transform filters. Furthermore, this scheme can coexist with traditional WDM channels and be a promising technique for seamless upgrade of transmission date rate.

摘要

提出并通过实验证明了一种使用单源的偏振复用差分四相相移键控（PolMux-DQPSK）格式的全光采样正交频分复用（OFDM）方案。具有3.07比特/秒/赫兹频谱效率的5×200 Gb/s全光采样正交频分复用（AOS-OFDM）信号通过光傅里叶变换滤波器进行实时检测，成功在80公里的单模光纤（SMF）链路上传输。此外，该方案可以与传统波分复用（WDM）信道共存，是一种有望实现传输数据速率无缝升级的技术。
