What is the RJ45 interface ?


The RJ45 interface is usually used for data transmission, and the most common application is the network card interface.


RJ45 is a type of various connectors; RJ45 headers have two different methods according to the order of the lines, one is orange-white, orange, green-white, blue, blue-white, green, brown-white, brown; the other are green-white, green, orange-white, blue, blue-white, orange, brown-white, brown


There are also two types of lines that use RJ45 connectors: straight-through lines and cross-over lines.


RJ45 type network card interface


100base tx RJ45 interface is a commonly used Ethernet interface, supporting 10M and 100M adaptive network connection speed


There are two types of common RJ45 interfaces: DTE type used for Ethernet network cards, router Ethernet interfaces, etc., and DCE type used for switches, etc.


DTE can be called data terminal equipment, and DCE can be called data communication equipment.


In a sense, a DTE device is called an active communication device, and a DCE device is called a passive communication device.


When two devices of the same type use the RJ45 interface to connect for communication, a crossover cable must be used.


RJ45 type network cable plug, also known as crystal head, is made of eight cores and is widely used in the connection of network cables between network devices of LAN and ADSL broadband Internet users.


RJ45 and RJ11, different standards, different sizes. Due to the different sizes of the two, RJ11 is 4 or 6 pins, and RJ45 is an 8-pin connection device. Obviously, RJ45 plugs cannot be inserted into RJ11 jacks.
