A 40km FIBER-OPTIC MICROWAVE SUBCARRIER MULTIPLEXING TR ANSMISSION SYSTEM FOR MULTI-CHANNEL FM-TV

摘要

The experiment that a 1.3μm 40km fiber-optic microwave multicarrier transmission system transmits multi-channel satellite FM-TV was demonstrated. All photoelectric modules arc domestic products in the system. The system characteristic of carrier to noise ratio (CNR) was measured and analysed. 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.
