本文介绍了一种用于光纤无线电系统的超三倍技术，用于毫米波频段内多业务无线信号的光产生和多路复用。为了实现该技术，在中站采用抑制载波调制的光单边带，在基站采用光阻带滤波。利用该技术，实验验证了数据比特率为1.25 gb /s的38.5 ghz幅移键控和41 ghz差分相移键控信号，在10公里光纤传输后，获得了误码率为10^{-8}$的功率损失约为1 dB。测得38.5 ghz信道链路的无杂散动态范围为65 $\hbox{dB}\cdot\hbox{Hz}^{2/3}$， 41 ghz信道链路的无杂散动态范围为70 $\hbox{dB}\cdot\hbox{Hz}^{2/3}$，两者的相位噪声均为${-}$70 dBc/Hz。
A super-tripling technology used in radio-over-fiber systems is presented in this letter for the optical generation and multiplexing of multiservice wireless signals within a millimeter-wave band. To realize the technology, optical carrier suppression is followed by optical single sideband with suppressed carrier modulation in the central station and optical stopband filtering in the base station is utilized. With the technology, 38.5-GHz amplitude shift keying and 41-GHz differential phase-shift keying signals both with 1.25-Gb/s data bit rate were demonstrated experimentally, and power penalties of about 1 dB at a bit-error rate of $10^{-8}$ were obtained after both signals transmitted over 10 km fiber. The spurious-free dynamic range of the link was measured to be 65 $\hbox{dB}\cdot\hbox{Hz}^{2/3}$ for the 38.5-GHz channel and 70 $\hbox{dB}\cdot\hbox{Hz}^{2/3}$ for the 41-GHz channel, both with the phase-noise at about ${-}$70 dBc/Hz.
