摘要
将空分复用技术与DWDM(密集波分复用)技术相结合, 在国内首次实现了560 Tbit/s相干光双偏振DFT-s(离散傅里叶变换)OFDM(正交频分复用) 32QAM(正交幅度调制)信号传输10 km单模7芯光纤的演示实验。系统使用了16个独立光源产生375个25 GHz栅格的DWDM信道, 单芯传输容量为85.91 Tbit/s, 7芯传输总容量为601.36 Tbit/s。系统使用普通FEC(前向纠错)编码, 解码门限为3.8×10-3, 编码冗余为7%, 系统净传输速率为562.02 Tbit/s, 净谱效率为59.95 bit/s/Hz。
Abstract
In this paper, we combine the Space Division Multiplexing (SDM) and Dense Wavelength Division Multiplexing (DWDM) technologies to experimentally demonstrate 560 Tbit/s coherent optical dual-polarization DFT-s Orthogonal Frequency Division Multiplexing (OFDM) 32 Quadrature Amplitude Modulation(QAM) signal transmission over 10 km single-mode 7 core fiber. The system uses 16 independent laser sources to generate 375 DWDM channels with 25 GHz grid. The channel capacity for single core is 85.91 Tbit/s and the total channel capacity for the 7 core fiber is 601.36 Tbit/s. After excluding the 7% Forward Error Correction(FEC) which aiming at the threshold of 3.8×10-3, the net data rate is 562.02 Tbit /s with spectral efficiency of 59.95 bit/s/Hz.
