摘　　要：使用国产光器件实现了１．３μｍ４０ｋｍ单模光纤微波副载波复用１２路卫星调频电视宽带传输系统的实验。传输带宽为５００ＭＨｚ（０．９７～１．４７ＧＨｚ），光纤线路总损耗为１７ｄＢ。测量并分析了系统的载噪比特性，两者相符得很好。该系统经受了长期运转实验，工作稳定。The experiment that a 1. 3μm 40km single-mode fiber-optic microwave multicarrier transmission system using domestic photoelectric transmits multi-channel satellite FM-TV was demonstrated. The transmission bandwidth of the system is 500MHz (0. 97～ 1. 47GHz). Total light power loss of the fiber link is 17 dB. The system characteristic of carrier to noise ratio (Re/N ) was measured and analysed. The analysed results agree well with measured data. After experienced the long-term experiment the system operates in stability.
