我们提出了一种双向光纤无线电链路，包括采用光倍频原理的光下行传输、远程本地振荡器（LO）生成、射频上行信号的远程下变频和采用强度调制直接检测的光上行传输。实验证明，64电平正交调幅无线电信号在下行链路上经过4.4公里多模光纤、12.5公里单模光纤和25公里单模光纤传输后，上转换到17.8 GHz；根据采用光产生的LO的下转换损耗来评估上行链路性能。
We propose a bidirectional radio-over-fiber link consisting of an optical downlink transmission employing the optical frequency multiplication principle, a remote local oscillator (LO) generation, a remote down-conversion of the radio-frequency uplink signals, and an optical uplink transmission employing intensity modulation-direct detection. Experiments demonstrate the optical up-conversion of 64-level quadrature amplitude modulated radio signals to 17.8 GHz after transmission over 4.4 km of multimode fiber, 12.5 and 25 km of single-mode fiber in the downlink; the uplink performance is evaluated in terms of down-conversion loss employing the optically generated LO.
