As we enter a data-driven world, the importance of Ethernet becomes more prominent. Fundamentally, Ethernet is a technology that connects computers to form a local network, through which devices can communicate with other devices. However, over time, Ethernet has evolved into a global data communication system, with speeds ranging from the initial 10Mbit\/s to the current 800G, and even 1.6T. This huge progress is not without challenges, but each breakthrough represents a great leap in technology.<\/p>\n\n\n\n
