摘　　要：研究了基于Xilinx Virtex-5 FPGA的光互连网络技术,通过FPGA板内的高速串行收发器连接SFP光收发模块,实现高速串行数据收发,每通道的传输速率达到3.125Gb/s,提出并实现了基于FPGA的四节点单向环形光互连网络。在ISE设计环境下,设计了基于两块FPGA板的FFT运算应用和基于四块FPGA板的具有随机消息分布特性的网络应用,完成了光互连网络的性能测试分析。The technology of optical interconnection network based on the Xilinx FPGAs is carefully studied in this paper. By using small form-factor pluggable （SFP） connector which is connected to the Rocket I/0 GTP inside the FPGA development board, the high speed serial data transmission can be realized with channel transmission rate up to 3.125Gbit/s. The four-node unidirectional toms optical interconnection network based on FPGA is proposed and implemented. The FFT computing applications based on the two FPGAs and net- work application which has the random traffic pattern based on four FPGAs are designed in the ISE design en- vironment, using to test and analyze the performance of the optical interconnection network.
