我们通过实验证明了标准单模光纤（SSMF）在355公里的跨度上以11b /s/Hz的净频谱效率传输101.7 tb /s。共使用了370个密集波分复用（DWDM）信道，跨越光学C和l波段，间隔为25 GHz。每个25 ghz信道被细分为四个子带，每个子带在每个调制子载波上携带一个73.5 gb /s正交频分复用（OFDM）信号，该信号由偏振分复用（PDM） 128位正交调幅（QAM）调制。本实验通过数字信号处理（DSP）对发射机损伤进行预均衡、全拉曼放大、外差相干检测，并对信道和接收机损伤进行DSP后处理，包括基于导频的相位噪声补偿。
We experimentally demonstrate 101.7-Tb/s transmission over 355 km spans of standard single-mode fiber (SSMF) at a net spectral efficiency of 11 b/s/Hz. A total of 370 dense wavelength-division multiplexed (DWDM) channels spanning the optical C- and L-bands spaced at 25 GHz were used. Each 25-GHz channel were subdivided into four subbands, with each subband carrying a 73.5-Gb/s orthogonal frequency-division multiplexed (OFDM) signal modulated with polarization-division-multiplexing (PDM) 128-ary quadrature amplitude modulation (QAM) at each modulated subcarrier. This experiment was enabled by digital signal processing (DSP) pre-equalization of transmitter impairments, all Raman amplification, heterodyne coherent detection, and DSP postequalization of the channel and receiver impairments, including pilot-based phase noise compensation.
