Abstract:

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.
