What is the definition of RJ45 network cable interface and what is it used for?

1. Network cable interface, namely RJ45 interface

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

3. RJ45 is a type of various connectors, for example: RJ11 RJ12 is also a type of connector, but it is used on telephones

The RJ45 interface refers to a modular plug or plug standardized by IEC(60)6037.

Uses 8 positions defined by international connector standards

IEC(60) 6037 is also the reference standard for the ISO/IEC11801 international general wiring standard for connecting hardware.

Ethernet has an interface using RJ45, as well as a home router and a computer broadband interface, which is RJ45

Unlike RJ11, RJ11 is equivalent to a phone line, connected to a modem, and the modem dials on the phone line
 
1. Definition of RJ45 interface RJ45 not only has interface, but also corresponding crystal head, mainly refers to 8-pin connector, mainly used for Ethernet, "RJ" means registered jack, "45" means interface standard serial number.

RJ45 usually connects the end to an Ethernet cable, which is used to connect various network devices such as computers, routers, switches, etc.

2. Types of RJ45 Interfaces There are many types of RJ45 interfaces, which are mainly divided according to cable standards. Common ones include Category 3, Category 5e, Category 6, Category 6e, etc.

RJ45 plug, also known as RJ45 crystal plug (RJ45 Modular Plug), is used for the termination of data cables to realize the connection and change between equipment and distribution frame modules.

The RJ45 crystal head is required to have good conduction performance; the gold-plated thickness of the contact three-pronged reed is 50μm, which meets the Super 5 transmission standard and conforms to the T568A and T568B line sequence; it has the functions of preventing loosening, plugging and unplugging, and self-locking.

The RJ45 plug is a standard connector in copper wiring, and it and the socket (RJ45 module) together form a complete connector unit. The connector composed of these two components is connected between the wires to realize the electrical continuity of the wires.

It is also an integral part of the finished jumper of the integrated wiring technology, and the RJ45 crystal head is usually connected to both ends of the twisted pair cable.

In the standard integrated wiring design and installation, this accessory product is usually not listed separately, that is, it is not recommended that the user complete the connection between the twisted pair and the RJ45 plug by himself.
 
RJ45 plugs are divided into two types: unshielded and shielded.

The shielded RJ45 plug is covered with a shielding cladding, and its physical appearance is no different from that of an unshielded plug.

There is also an industrial shielded RJ45 plug specially designed for the factory environment, which is used in conjunction with the shielded module.

There will also be an RJ11 interface on the home ADSL Modem, which is slightly smaller than the RJ45 interface and is mainly used to connect telephone lines.

It should be noted that the RJ11 interface is 4 or 6-pin, and the RJ45 is an 8-pin interface, so the RJ45 plug cannot be inserted into the RJ11 interface, and the RJ11 plug cannot be inserted into the RJ45 interface.

The RJ45 fixed link is backward compatible with RJ11, and the 3-6 and 4-5 pairs of RJ45 correspond to the 1-4 and 2-3 pairs of RJ11.
