Abstract

We propose a computationally efficient and frequency-offset-tolerant channel estimation and synchronization method for polarization-division-multiplexed (PDM) coherent optical OFDM (CO-OFDM). Using this method, we demonstrate a 43-Gb/s PDM CO-OFDM transmission with 16-QAM subcarrier modulation over 5,200-km of ultra-large-area fiber.

PDM CO-OFDM传输中一种有效且容频偏的信道估计与同步方法

提出了一种计算效率高、可容忍频偏的偏振分复用(PDM)相干光OFDM (CO-OFDM)信道估计和同步方法。使用这种方法，我们演示了在5200公里的超大面积光纤上使用16-QAM副载波调制的43gb /s PDM CO-OFDM传输。
