摘要
提出了基于ARM9处理器和千兆以太网交换芯片的ONU设计,分析了两大硬件模块的构成与主要线路连接,整个设计采用嵌入式设计方法。经过验证,该设计的ONU满足中国电信提出的EPON设备技术的相关要求,非常符合目前"光纤到楼"工程的推进。
This paper presents the design of ONU based on ARM9 processor and Gigabit Ethernet switching chip, then analyzes the two blocks of the ONU and mainly circuit connection. The whole design is based on embedded design method. After verification, the ONU can meet the EPON equipment requirements raised by China Telecom and are greatly in line with the evolution of China＇s ＇Fiber To The Building＇ project.
