摘　　要：文章提出了一种基于FPGA技术来实现SDH环网保护的方法,其核心是根据本地光模块的SD信号,由FPGA内部的状态机来控制环回芯片,从而实现保护的功能。该设计硬件架构简单,恢复时间快,可靠性高,且兼容单纤双向和双纤双向2种光模块,可以很好地满足环网拓扑对保护功能的需求。A method to realize SDH ring network protectionbased on FPGA technology has been used,its core is according to the SD signal of local optical transceivers,controlled by FPGA internal state machine to loop back to the chip,so as to realize the functions of protection. The method is simple in hardware architecture and faster recovery time,high reliability,and compatible with BIDI transceiver and dual fiber transceiver,can well meet the demand for protection of ring network topology
