摘　　要：在现有SDH设备网管信息传输方案基础上,提出了一种基于以太网交换的SDH设备网管信息传输方案,利用FPGA实现了网桥的协议转换以及开销字节映射功能,并增加了光纤成环自动判断功能。Based on the analysis of the SDH network management information transmission scheme,the imple- mentation method of SDH network management information based on ethernet technology is designed.The ethernet bridge function and SDH overhead bytes mapping is implemented based on FPGA and the judgment of fiber ring is designed.

关 键 词：SDH 网管信息 开销字节
