提出了一种基于2通道相位调制器（2通道PM）的宽带色散补偿方案，并在长距离模拟光链路中进行了实验验证。利用2路相位调制同时获得相位调制和强度调制链路的互补功率衰落函数，实现了宽带长距离色散补偿。实验结果表明，色散引起的功率衰落大大减轻了射频（RF）信号的带宽高达18 GHz超过24.45公里的单模光纤（SMF）传输。同时，系统的无杂散动态范围（SFDR）也得到了提高，在17.5 GHz处最大值为24，矢量信号传输性能也得到了改善。
A broadband dispersion compensation scheme based on a 2-Ch phase modulator (2-Ch PM) is proposed and experimentally demonstrated in the long-haul analog optical link. Benefiting from the complementary power fading function for the phase and intensity modulated link, which are simultaneously obtained by using the 2-Ch PM, the broadband and long-reach dispersion compensation is implemented. The experimental results show that the dispersion-induced power fading is greatly mitigated for the radio frequency (RF) signal with a bandwidth up to 18 GHz over 24.45-km single-mode fiber (SMF) transmission. Meanwhile, the system spurious-free dynamic range (SFDR) is improved with a maximum value of 24 at the frequency of 17.5 GHz; the vector signal transmission performance has also been improved.
