摘　　要：为了解决板级间并行接口无法满足高速率数据传输的问题,提出了基于FPGA的高速串行光纤数据传输的设计方案。采用Virtex-7系列FPGA作为主控芯片,通过芯片内部集成的高速串行收发器GTX连接SFP+光模块,进行了高速串行接口设计,并介绍了Aurora串行传输协议的设计。通过分析Xilinx专用调试工具集成比特误码率测试仪IBERT对光纤链路的测试以及Chipscope抓取板卡上的实际测试结果,在硬件上实现了串行传输速率为10 Gbps的光纤数据传输。In order to solve the problem that parallel interface between boards can＇t meet the requirement of high-speed data transmission,a design scheme of high-speed serial optical fiber data transmission based on FPGA is proposed. This design uses Xilinx Virtex-7series FPGA as the main control chip. And the high-speed serial interface design was carried out through the chip internal integration of GTX transceiver link SFP ＋ optical module.The hardware circuit is designed.And the design of Aurora serial transmission protocol is introduced. Xilinx special debugging tools IBERT to test fiber link is analyzed and the actual test results on the board captured by Chipscope is presented.Finally the serial data transfer rate of 10 Gbps optical fiber transmission is achieved with hardware implementation.
