Along with the development of high-resolution remote sensing satel ite and spacecraft, researches on high-speed data transmission system are with great importance. This paper realized a high-speed data transmission system based on an FPGA chip. The system mainly contains two modules, the fiber optic communication module and the PCIe communication module. Fiber optic communication is realized by connecting the fiber transceiver with the GTX inside the FPGA chip. Data received by the fiber optic communication module is processed and transmitted to the computer through the PCIe bus. Final y, the system implemented and tested. Experiments results indicated that the system features high-speed, high-reliability and high-stability, and is with great applications.
