抽象的。基于循环移频器，我们产生了20个高质量的多载波光梳，其信噪比>25 dB。我们还实验证明了2.56-Tb/s，偏振分复用归零16进制正交幅度调制，相干光波分复用传输800公里的标准单模光纤与25 GHz的信道间隔，和频谱效率为5.1 B/s/Hz。
Abstract. Based on recirculating frequency shifter, we generate 20 high-quality multicarrier optical combs with a tone-to-noise ratio >25 dB. We also experimentally demonstrate 2.56-Tb/s, polarization division multiplexing return-to-zero 16-ary quadrature amplitude modulation, coherent optical wavelength division multiplexing transmission over 800 km standard single-mode fiber with 25-GHz channel spacing, and the spectrum efficiency is 5.1 b/s/Hz.
