基于光纤传输的模拟信号远程复现装置OA

In order to solve the problems of large amount of data,long distance and high real-time in the remote reproduction of analog signals,an analog signal remote reproduction device based on optical fiber transmission is designed.A high-precision A/D converter is used to convert analog signals into digital signals,and the RocketIO module embedded in FPGA is used to frame and pack the digital signals,and then the signals are loaded into the SFP optical fiber transceiver module and sent to the remote end through the optical fiber.In the analog signal receiving and reproducing module,the SFP optical fiber transceiver module is used to receive the signal,and the RocketIO module of FPGA is used to decode and unframe the received signal,and the high-precision D/A converter and filter circuit are used to process and reproduce eight analog signals synchronously.The results show that the device can realize the high-speed synchronous acquisition of multi-channel analog signals and real-time transmission to the remote reproduction,which is suitable for the remote real-time interaction of multi-channel analog signals among distributed test equipment.
