摘要
本文使用国产光电器件研制了光纤微波副载波传输系统.进行了C波段卫星信号下转换第一中频信号经1.3μm单模光纤传输38.78公里的现场实验.光纤线路总损耗17dB.分析了系统的互调和载噪比特性,与实验结果相吻合.系统经长期运转实验,工作稳定.
Using the domestic photoelectric products, the fiber-optic microwave subcarrier multiplexing transmission link was developed. The experiment of the first intermediate frequency signal from down-converted C-band downlink satellite signal through a 1. 3um 38. 78km single-mode fiber link was demonstrated. Total light power loss of the fiber link is 17dB. The system characteristics of the intermodulation and the carrier to noise ratio were analysed and agree well with measured data. After long-term experiments the system operates stably.
