What is Registered Jack

RJ stands for Registered Jack, it’s a standardized telecommunications network interface for connecting voice and data equipment to a local exchange carrier or long-distance carrier. It is a standardized network interface used for network cabling, wiring and jack construction.

The Function of  Registered Jack

The primary function of the Registered Jack is to connect different data devices and telecommunications equipment to services normally provided by telephone exchanges or long-distance carriers. The different standard designs of RJ connectors and wiring are RJ-11, RJ-45, RJ-21, RJ-28, etc.

The RJ45 port is a data interface commonly found on computers, network routers, switches, and hubs, and is known by the technical term RJ-45 connector. The most common RJ-45 port uses four 8P8C wires for Ethernet communication.

The Types of Registered Jack

Generally, there’re types of RJ11, RJ14, RJ25, RJ45, RJ48,etc. For example, RJ11, RJ14, and RJ25 are the most commonly used interfaces for telephone connections for one-, two-, and three-line service, respectively. Although these standards are legal definitions in the United States, some interfaces are used worldwide.

The difference between RJ11 and RJ45

RJ45 interface is now our most common network equipment interface, commonly known as the “Modular Connector”, the professional term for RJ-45 connector belongs to the twisted-pair Ethernet interface type.

The RJ45 connector is an 8-position, 8-contact (8P8C) modular plug and jack for Ethernet-based local area networks (LANs).The RJ45 cable plug is usually made of plastic and has eight pins on the port. Four of these pins are used for sending and receiving data, and the other four are used for other technical or power networking equipment.

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

In addition to the RJ45 interface, some other connector types, such as the RJ11 interface, may confuse you in some cases. RJ11 has **6P2C or 6P4C configuration** for connecting a single phone line. RJ45 uses **8P8C configuration**. RJ45 and RJ11, the main difference is the number of wires in their connectors. Look closely and you will see that the RJ45 has 8 wires in it, while the RJ11 has 4 wires, resulting in a larger RJ45 than the RJ11.

As mentioned above, the RJ11 plug supports limited bandwidth applications, including phone lines and ADSL connections, through 2 or 4 of the 6 available connection points. The RJ45, on the other hand, uses an 8P8C configuration with more available connection points, so the RJ45 can be used for data-intensive applications such as Ethernet and can support bandwidths up to 10 Gbps. the RJ45 is sometimes used for VoIP calls in the office as well.

Cables with RJ45 connectors on both ends are called RJ45 Ethernet cables. cat5, cat6, and cat7 cables are the most common RJ45 cables used for network connectivity today. Compared to RJ11, RJ45 is suitable for more applications such as Ethernet networking, telecommunications, factory automation, etc. It is often used for network devices including Ethernet cables, modems, computers, laptops, printers, etc.
