The experiment that a 1. 3 μm 40 km fiber-optic microwave multicarrier transmission system transmits multi-channel satellite FM-TV was demonstrsted. All photoelectric modules are domestic products in the system. The system characteristic of carrier to noise ratio (CNR) was measured and analyzed. The analysed results agree well with measured data. Total light power loss of the 40km fiber link is 17 dB. After experiencing the long-term experiment the system operates in stability.
