Design of Optical Fiber Transmission System for Four-Channel Video and Audio Signals

LIN Lin,WANG Jia-xian,LING Chao-dong (College of Information Science and Engineering,Huaqiao University,Quanzhou 362021,China)  
A special-application digital optical fiber transmission system is designed by using programmable logic devices,serial-to-parallel converters and optical transceivers.The multi-channel analog baseband video and audio signals are digitalized and converted to high speed data flow.These parallel high speed data flows are multiplexed using TDM technology in FPGA and converted to a serial data flow.Then the serial data flow is outputted to the optical transmitter and coupled into optical fiber to transmit finally.The receiver restores original analog baseband signals through the inverse process.The experiment results show that the system works stable and reliable in the case of real-time transmission.
