To achieve the high integration and high-speed of transmission system directly from the sensor interface to the light interface,a multi-sensor integrated optical fiber transmission system based on FPGA was proposed. The hardware platform of the optical fiber transmission system was built with the simple architecture based on FPGA and optical transceiver module. And on this basis,the intelligent software of the system was developed. The system realized the data acquisition and transmission of analog and digital-interface＇s sensor. By applying the principle of time division multiplexing,the multi-channel sensor signal by single fiber was realized. The experimental results indicate that the system has the ability to detect the error code. The system is very suitable for industrial field sensor signal transmission of long transmission distance and high real-time in complex environment.
