摘　　要：针对传统硬件组成和系统设计难以实现光通信终端产品验证的要求,结合现场可编程门阵列(Field-Programmable Gate Array,FPGA)在逻辑规划、信号处理等方面的优势搭建了一套完整的光通信终端产品多路自动测试系统。以介质访问控制(Media Access Control,MAC)为基础对信息层、物理层等诸多环节进行逐一设计和检测,并采取环路滤波器对信号处理的性能进行优化,满足系统对于稳定性、可靠性的要求。通过模拟分析和信息流程验证,该系统能够有效实现光通信终端产品的多路并行自动检测,具有较好的应用效果,具备一定的借鉴意义。Aiming at the requirements that traditional hardware composition and system design are difficult to realize the verification of optical communication terminal products,combined with the advantages of Field-Programmable Gate Array(FPGA)in logic planning and signal processing,a complete set of optical communication is built.Multi-channel automatic test system for terminal products.Based on Media Access Control(MAC),the information layer,physical layer and many other links are designed and tested one by one,and loop filters are used to optimize the performance of signal processing to meet the system's requirements for stability and reliability requirements.Through simulation analysis and information flow verification,the system can effectively realize multi-channel parallel automatic detection of optical communication terminal products,which has good application effect and has certain reference significance.
