Understand the RJ45 connector!

Differences between RJ45 and RJ11: different standards, different sizes. Because the two plug sizes are different (4 or 6 pins for RJ11 and 8 pin for RJ45) , it is clear that the RJ45 plug can not be inserted into the RJ11 socket. On the contrary, it is physically possible (the RJ11 plug is smaller than the RJ45 plug) to give the false impression that the two plugs should or could work together. Not really. Firmly oppose the use of RJ11 plug in RJ45 jack. Because RJ11 is not an international standard, its size, insert strength, insert angle and so on are not designed according to international standards, so it can not guarantee interoperability. They have even caused damage on two fronts. Because the RJ11 plug is smaller than the RJ45 jack, the plastic parts on either side of the plug will damage the pin Jack.

What is an RJ45 connector? RJ45 connector is mainly used for data transmission, the most commonly used is network card connector. RJ45 is a variety of different seams; RJ45 seams according to the alignment of the two methods, one is orange, orange, cyan, blue, green, brown-red, brown-red; The other is green-white, green, orange, blue, blue, white, reddish-brown and reddish-brown; therefore, the use of RJ45 seams can also be divided into two types of line: straight line and junction line. The commonly used Ethernet connector is the 10100BASETXRJ45 connector, which supports 10 megabit and 100 megabit adaptive network connection speeds, there are two common types of RJ45 connectors: DTE-type Ethernet cards, router Ethernet connectors, and DCE-type switches. We can call DTE“Data terminal device” and DCE“Data communication device”. A DTE device is in some sense called an“Active communication device” and a DCE device is called a“Passive communication device”. If you use an RJ45 connector to connect two identical devices to communicate, you must use a cross-wire connection. RJ45 network cable plug, also known as Crystal Plug, made of 8-core, widely used in local area network and ADSL broadband internet users between the network equipment cable connection (called five-level wire or twisted pair) .
