摘要
为满足当前高速光纤通信领域对海量数据记录的需求,在继承PCI Express总线技术和磁盘阵列存储技术最新成果的基础上,设计并研制了一台可接入2.5Gbps光纤信号的记录仪;该系统由光纤数据采集卡、上位机、磁盘阵列及相应的应用软件和驱动程序共同构成;通过对采集存储机制的合理设计,有效地解决了记录仪工作中面临的处理带宽瓶颈问题;试验测试表明,该记录仪可连续记录2.5Gbps光纤信号达40分钟之久。
For meeting the need of recording mass storage data in the field of high-speed optical communications,a set of 2.5Gbps fiber-optic data recorder was designed and implemented based on the technologies of PCI Express bus and RAID.The system includes a fiber-optic data acquisition card,a host computer,RAID and their corresponding application software and driver.The bottleneck of processing bandwidth in recording was overcome by appropriately designing the mechanism of acquisition and storage.Test results show that the system can record 2.5Gbps fiber-optic data continuously for 40 minutes.
