Let’s think of some very cool names of some simple but vital objects that we use in daily life … You have a lot of things to think of, but we want to talk to you about RJ45.
RJ45… you think the name of a high-tech robot in the space station… or a powerful weapon… maybe one of the most important elements in the world… RJ45 is a connector with 8 metal connection points on it. It is located at the end of the connection cables called ethernet used in communication between computers and connecting computers to the local network. It is the larger connector used in telephone connections and called RJ11. There is a certain standard when attaching cables to the RJ45 jack. These standards are called T568A and T568B. One of these is preferred when wiring on a network. You can connect with white orange, orange, white green, blue, white blue, green, white brown, brown as a result of the correct alignment. Your cable connection should end in a connector that needs to be plugged in. RJ45 is a standard physical connector specifically for network cables used for Ethernet networking. And 45 is the number of interface standard. Recently, RJ45 connectors are commonly seen with Ethernet cables and networks. Ethernet cables with RJ45 connectors are also called RJ45 cables. Modern Ethernet cables have a small plastic plug at each end of the cable. The plug is inserted into the RJ45 jacks of Ethernet devices.
The RJ45 connector is the most common twisted pair connector for Ethernet cables and networks. RJ stands for registered jack, which is a standardized telecommunications network interface for connecting voice and data equipment to a service provided by a local exchange carrier or long distance carrier. The physical connectors that use jacks are mainly modular connector and 50 pin miniature ribbon connector types. The RJ45 connector is an 8-position, 8-contact (8P8C) modular plug and jack commonly used to connect computers to Ethernet-based local area networks (LANs). The RJ45 cable plug is usually made from an eight-pin plastic piece on the port. Four of the pins are used for sending and receiving data, while the other four are used for other technologies or power network devices.
There are two wiring schemes: T568A and T568B, used to terminate the twisted pair cable to the connection interface. The two standards define how the RJ45 connector will adjust each of the eight wires when connecting the RJ45 connector to one cable. These wiring layouts have their own color convention, and following convention it is important to ensure electrical compatibility.
Regarding the two standards, there are two different connection forms. T-568B wiring scheme is most commonly used, some devices also support T-568A wiring scheme. It is a straight connection if both ends of the connecting cables are wired on a standard basis. Both standards can be used over straight cable. If not, it’s a cross link. Some network applications require a crossover Ethernet cable with a T-568A connector on one end and a T-568B connector on the other. This type of cable is generally used for direct computer-to-computer connection when no router, hub or switch is available.
As you can see, it would be unfair if we define it as groundbreaking cable order, interesting pliers, cool cool expressions to provide an internet connection or a local connection, but even saying RJ45 is very cool… RJ45 wow wow…
