摘　　要：本文实现了１．３μｍ４０ｋｍ光纤微波副载波复用多路卫星调频电视传输系统实验。系统中的光电组件均为国产。测量并分析了系统的载嗓比特性，两者相符得很好，４０ｋｍ光纤的总损耗为１７ｄＢ。该系统经受了长期运转实验，工作稳定。Abstract：The experiment that a l．3um 40krn fiber- optic n1icrowave multicarrier trans-mission system transmits muIti-channel satellite FM－TV was demonstrated．All photoelectricmodules are domestic products，The system characteristic of carrier to noise ratio（CNR） wasmeasiJred and analysed．The analysed results agree well with measured data. Total light pow-er loss of the 40km fiber link is around 17dB. After experienced the long-term experimenetthe system operates in stability.
