摘　　要：简述了RadiooverFiber(ROF)通信技术,从理论和VPI仿真实验两方面系统地分析研究了光纤色散问题对ROF光通信系统的影响。理论分析和仿真结果吻合。最后,对ROF单、双波长各调制情况的光纤色散影响给出了归纳、比较和总结。Brief introduction of Radio over Fiber （ROF） communication technology and research on effect of fiber dispersion on ROF optic communication system are given. Dispersion problem of single wavelength and two-wavelength modulation ROF systems is analyzed systematically with theory and simulation experiment, and theoretic analysis accords with simulation experiment results well. Finally, design index of dispersion in ROF optical communication is presented, and fiber dispersion effects of single wavelength and two-wavelength modulation are concluded, compared and summarized.
