Design of High-speed Data Transmission System Based on Fiber-PCIE

Abstract

In this paper, a high-speed data transmission system based on optical fiber and PCIE is proposed. The system is implemented on the platform of Xilinx's FPGA. The Transceiver IP core in the FPGA is used to design the GTX high-speed interface, and the optical module with high-speed data transmission communication performance is selected for data transmission, and then the data is stored in DDR3. On the software side, PCIE communication logic is configured through embedded (SDK) development and exemplified XDMA IP core to achieve dynamic speed allocation, data receiving and sending, and data transmission. The reconfigurable technology of FPGA is used to configure different transmission rates of optical fiber communication by switching QPLL and CPLL during system operation, which increases the flexibility of the system. The physical test shows that the proposed system is effective in data transmission, has high data accuracy, and the transmission rate can be switched at any time.
