摘　　要：介绍了BESIII触发系统MDC子系统光纤发送插件的设计与测试。32通道的数据同步与展宽的实现由一片FPGA完成,基于RocketIO实现了1.75Gb/s波特率的串行数据光纤发送。文章给出了展宽电路和串行传输的测试结果。插件的设计达到了预期的设计目标。The design and test of MDC fiber transmitter in BESⅢ TRIGGER system are introduced in this article. The 32 channels of data are synchronized and stretched in FPGA. Based on RoeketIO, a serial transmission up to 1.75 Gb/s baud is established. The results of tests on stretching circuits and serial transmission are given out at last. The design of this transmitter achieves the preliminary design object.
