摘要

400G将是高速光传输领域的下一个关键技术,而当前单波400G高速传输方案暂时受限于传输性能和传输距离。展示了基于64QAM高阶调制的单波400G传输实验,能够实现在G.654光纤和拉曼放大器组成的光纤链路中进行1 000km长距离传输,实现净频谱效率为8 bit/s/Hz,单纤总容量可达到32 Tbit/s。
        400 G will be the key technology of the next generation high-speed transport system,and the application of single carrier 400 G is quite limited by the transmission performance and distance. The experiment based on 64 QAM single carrier in 400 G demonstrates that the transmission distance of 1 000 km can be achieved in G.654 fiber with Raman amplifier,spectral efficiency can reach 8 bit/s/Hz,which enables the capacity of single fiber to reach 32 Tbit/s.
