摘要
介绍一个采用国产光电器件研制的微波副载波复用光纤视频传输系统。系统进行了以传输亚洲一号卫星信号地面接收站第一中频多路电视信号为目标的现场实验。信号经过３８．７８ｋｍ，１．３μｍ波长单模光纤传输后，在接收光功率为－２２ｄＢｍ时，载噪比劣化不大于３ｄＢ，当接收光功率为－３０ｄＢｍ时。
In this paper,the fiber optic microwave subcarrier multiplexing video transmission system using the domestic photoelectric products is introduced.The experiment of the first intermediate frequency FM FDM video signal from Asia satellite l was demonstrated.After the signal transmissing through 1.3 μm 38.78 km singlemode fiber link,and when the received optical power is -22 dBm,the C/N deterioration is smaller than 3 dB.When the recieved optical power is equal to -30 dBm,the image quality is still good.
