GEM中子束监测器光纤传输PCIe卡

摘要

介绍了一种用于中国散裂中子源GEM中子束监测器的光纤传输PCIe卡的设计,简要介绍了项目背景,重点描述了高速光纤模块和PCIe模块的结构和实现方式,测试结果表明该设计能稳定运行5Gb/s光纤传输,PCIe单通道传输速率接近2.5 Gb/s.%A high speed data acquisition card is designed, which will be used in Neutron Beam Monitor on GEM of CSNS, and the background of this project is briefly described , moreover , the architecture of the optical fiber module and the PCIe module is emphasized . Finally it gives the test results of the corresponding modules.
