摘　　要：本文报道了一个利用国产光电器件可同时传输１２路彩色电视信号的调频（ＦＭ）副载波复用（ＳＣＭ）光纤传输实验系统，同时给出了现场传输７路调频卫星电视信号的初步实验结果。在接收端采用了谐振式接收技术，提高了系统的灵敏度，使系统的载噪比（ＣＮＲ）特性的测试结果接近于理论分析的量子极限。This paper reports a 12-channel FM-video subcarrier multiplexed(SCM) lightwave system utilizing the optoelectronic devices all made in China and gives initial experimental results of field transmission of 7 channel FM-video. The resonant receive techniques in the receiver improves the system sensitivity and makes the carrier-to-noise ratio(CNR) performance approach theoritical quantum limitation.
