摘　　要：提出一种实时数字化光纤传输系统,该系统分为发送端和接收端。发送端用A/D转换器将输入的模拟信号数字化,再用FPGA对数据进行处理,并通过光纤传输。同时,FPGA还控制A/D转换器的工作。接收端用串行收发器TLK1501对接收数据进行解码处理,还原有效信号。实验表明,该系统实时性好、信号传输误码率低、工作性能稳定、抗干扰性强,系统具有可行性和有效性。A real-time digitized optical fiber transmission system composed of the transmitting part and receiving part is proposed.The transmitting part digitizes input analog signals by the A/D converter,and then FPGA processes the digital signals and transmits the signals by the optical fiber.FPGA also controls the A/D converter.In the receiving part,the TLK1501 transceiver decodes the received signal in order to restore the effective signals.Results of experiments show that the system has the merits of good real-time performance,low Bit Error Rate,good stability and strong anti-jamming ability.The system is feasible and effective.
