| 摘 要： | 分析了本振信号传输时光纤色散引发的相噪对矢量信号EVM的影响规律,提出了抑制此类EVM恶化的上行RoF链路原理结构。实验结果表明:该结构在35km单模光纤时,可以将色散引起的相噪影响完全抑制;可将65km单模传输时的EVM从10%左右抑制为5%左右。

| Abstract: | The impact of dispersion-induced phase noise （PN）on the EVM of transmitted vector signals in radio-over-fiber （RoF） systems was investigated,and a RoF uplink scheme was proposed to suppress this kind of PN.Experimental results show that with the scheme the impact of dispersion-induced PN can be completely suppressed in case of 35 km transmission fiber and EVM can be decreased from about 10% to 5% in case of 65 km transmission fiber. |
