The difference between RJ45 and SFP Port for I210 NIC
The RJ45 interface is typically used in Ethernet LANs and Internet access scenarios. Its advantages include easy installation, configuration, and maintenance, as well as wide compatibility with most networking devices such as switches, routers, and computers.
The SFP interface is suitable for long-distance transmission, high-speed data transfer or special network environments (such as fiber optic networks). The SFP interface can use various types of optical modules, supporting different types of fiber and transmission distances.
