What are the ways to use the RJ45 connector?

RJ45 connector commonly known as crystal head. It is the transparent plug that connects the network card or HUB, and is used to connect the two ends of twisted pair cable. The RJ-45 is a network interface specification, similar to the RJ-11 interface, which we use to connect telephone lines. The reason why it is called“Crystal Head” is because of its crystal clear appearance. The RJ -45 plug must be installed on both ends of the twisted pair cable for network communication on the RJ -45 interface of the network card (Nic) , Hub, or Switch. The RJ-45 plug is a plastic joint that can only be inserted in a fixed direction and automatically prevents it from falling off, the technical term is RJ-45 connector (the RJ-45 is a network interface specification, similar to the RJ-11 interface, which we use to connect telephone lines) . The reason why it is called“Crystal Head” is because of its crystal clear appearance. The RJ -45 plug must be installed on both ends of the twisted pair cable for network communication on the RJ -45 interface of the network card (Nic) , Hub, or Switch. The sequence of pins from left to right is 1-8, many users often have two kinds of errors in wiring: one is to use a one-to-one connection method, when the connection distance is short, the system will not have connection failure, but when the connection distance is long, the network busy or high-speed operation, Z good use of the connection method in Figure 4, the core is to make 3 and 6 two pins for the same twisted pair.
