How to use the RJ45 connector connection network

RJ45 connector is commonly known as crystal head. The transparent plug that connects the network card or HUB is used to connect the two ends of the twisted pair.

RJ-45 is a network interface specification, similar to the RJ-11 interface, which is the "telephone interface" we usually use to connect the telephone line. It is called "Crystal Head" because of its crystal clear appearance. The RJ-45 plug must be installed at both ends of the twisted pair for plugging into the RJ-45 interface of the network card (NIC), hub (Switch) or switch (Switch) for network communication.

 

 

The RJ-45 plug is a plastic connector that can only be inserted in a fixed direction and automatically prevents falling off. It is commonly known as the "Crystal Head". The terminology is RJ-45 connector (RJ-45 is a network interface specification, similarly The RJ-11 interface is the "telephone interface" we usually use to connect the telephone line. It is called "Crystal Head" because of its crystal clear appearance. The RJ-45 plug must be installed at both ends of the twisted pair for plugging into the RJ-45 interface of the network card (NIC), hub (Switch) or switch (Switch) for network communication.

The order of the pins from left to right is 1~8, and many users often have two kinds of errors in the wiring: one is to use one-to-one connection method. When the connection distance is short, the system will not be connected. However, when the connection distance is long and the network is busy or running at high speed, it is better to use the connection method of Figure 4, the core of which is to make the 3 and 6 pins the same twisted pair.
