数字信号处理（DSP）与相位和偏振分集相干接收机相结合是未来光网络的一项有前途的技术。DSP不仅可用于消除对动态偏振控制的需求，还可用于补偿非线性和线性传输损伤。在本文中，我们展示了一个42.8 Gbit/s非线性传输实验的结果，该实验使用10.7 GBaud的偏振复用QPSK数据，每个符号4比特。数字相干接收机允许在标准单模光纤上传输6400 km后，对107424 ps/nm的色散进行数字补偿。（c）2007美国光学学会。
Digital signal processing (DSP) combined with a phase and polarization diverse coherent receiver is a promising technology for future optical networks. Not only can the DSP be used to remove the need for dynamic polarization control, but also it may be utilized to compensate for nonlinear and linear transmission impairments. In this paper we present results of a 42.8Gbit/s nonlinear transmission experiment, using polarization multiplexed QPSK data at 10.7GBaud, with 4 bits per symbol. The digital coherent receiver allows 107,424 ps/nm of chromatic dispersion to be compensated digitally after transmission over 6400km of standard single mode fiber.
