Meanwhile I solved the problem.The problem was the Ethernet preamble. The Preamble Problem (2500Base-X != 2.5G SGMII) Ethernet frames are preceded
1、10G 2、base 3、-R:64B/66B编码 -X:8B/10B编码 10GBase-SR:10GBase-SR中的"SR"代表"短距离"(short reach)的意思,该规范支持编码方式为64B/66B的短波(波长为850nm)多模光纤(MMF),有效传输距离为2～300m,要支持300m传输需要采用经过优化的50μm线径OM3(Optimized Multimode 3,优化的多模3)光纤(没...
另外,2500BASE-X 和 5000BASE-X 主机接口是什么意思?是分别只有SGMII 2.5G和SGMII 5G吗?我认为 X 用于通过光纤进行千兆位以太网传输,但在此上下文中,它用于上述部分数据表中的 MAC-PHY 接口。 0 2023-4-4 07:00:05 评论 淘帖 邀请回答 硬件工程师1 相关推荐 • LS2088A的工艺节点是什么? 221 ...
