| 摘 要： | 针对光载无线通信（RoF）系统的传输限制因素，文章提出并实验证明两种传输距离长性能高的RoF系统。一种是采用抑制奇数边带的基于外部调制的40GHz的RoF系统；另一种是采用载波抑制（OCS）的外部调制的40GHz光正交频分复用（OFDM）RoF系统。理论与实验证明这两个系统不仅抗色散能力强，而且可以实现远距离传输。

| Abstract: | To solve the transmission limitation in Radio over Fiber （RoF） system, in this paper two schemes are proposed for improving the transmission distance and performance in RoF system. One scheme is 40 GHz RoF system based on external modulation with odd-sidebands suppressed. The other scheme is 40 GHz Orthogonal Frequency Division Multiplexing （OFDM） RoF system based on Optical Carrier Suppression （OCS） external modulation. Two schemes have theoretically and experimentally investigated that these systems can resist chromatic dispersion and provide long distance transmission. |
