We report the transmission of five 30-GBaud dual polarization 16-QAM signals over 160 km of standard single-mode fiber in the E-band (1410-1460 nm). The transmission line consists of two 80-km spans and three independent bismuth-doped fiber amplifiers. The developed amplifiers feature a maximum gain of 27.3 dB, 33.8 dB, and 28.3 dB with a minimum noise figure of 4.8 dB, 4.7 dB, and 5.3 dB, respectively. The maximum signal Q factor penalty is 4.5 dB, and the overall performance of the system is above the pre-forward-error-correction (FEC) threshold for a 10 post-FEC bit error rate. To the best of our knowledge, this is the record experimentally demonstrated transmission length for a coherent detection signal in the E-band.
我们报告了在E波段（1410 - 1460纳米）的标准单模光纤上160公里传输5个30千兆波特双偏振16 - QAM信号的情况。传输线路由两个80公里的跨度段和三个独立的铋掺杂光纤放大器组成。所开发的放大器的最大增益分别为27.3分贝、33.8分贝和28.3分贝，最小噪声系数分别为4.8分贝、4.7分贝和5.3分贝。最大信号Q因子损失为4.5分贝，系统的整体性能高于前向纠错（FEC）后误码率为10时的预FEC阈值。据我们所知，这是E波段相干检测信号实验证明的传输长度记录。
