讨论了相干光正交频分复用(CO-ofdm)作为一种适合长距离传输系统的调制技术。回顾了CO-ofdm系统的设计和实现的几个方面，但重点讨论了相位噪声补偿。针对传统CO-ofdm传输系统对激光相位噪声非常敏感的问题，提出了一种新的相位噪声补偿方法。在这种相位噪声补偿方法的帮助下，我们展示了在4160公里的SSMF中，在25.8 Gb/S数据速率(编码后为20 Gb/S)下，在没有色散补偿的情况下可以连续检测到的OFDM码。
We discuss coherent optical orthogonal frequency division multiplexing (CO-OFDM) as a suitable modulation technique for long-haul transmission systems. Several design and implementation aspects of a CO-OFDM system are reviewed, but we especially focus on phase noise compensation. As conventional CO-OFDM transmission systems are very sensitive to laser phase noise a novel method to compensate for phase noise is introduced. With the help of this phase noise compensation method we show continuously detectable OFDM transmission at 25.8 Gb/s data rate (20 Gb/s after coding) over 4160-km SSMF without dispersion compensation.
