Do you want to enjoy a fast and reliable connection for your multimedia equipment? Do you want to transmit any type of digital signal throughout your home? Then you need to install RJ45 sockets. But which RJ45 color code should you choose? And how do you wire these sockets correctly? In this article, we'll teach you how to crimp an RJ45 cable with the correct color order!
To get a clearer understanding, follow this video tutorial to learn how to wire and respect the RJ45 color code !
What are the wiring standards for an RJ45 socket?
To properly wire an RJ45 socket , you must follow certain standards, namely T568A and T568B . These standards define the order of the wire colors to be inserted into the connector. The T568B standard is generally used in professional settings, while the T568A standard is used in residential settings. Regardless of your choice, ensure that you wire the sockets in your communication panel and the wall sockets correctly according to these standards.
RJ45 color code order
Here is an example of a table to compare the T568A and T568B standards:
| Position | Color T568A | Color T568B |
| 1 | White-green | White orange |
| 2 | Green | Orange |
| 3 | White orange | White-green |
| 4 | Blue | Blue |
| 5 | White-blue | White-blue |
| 6 | Orange | Green |
| 7 | White brown | White brown |
| 8 | Brown | Brown |
How do I connect an RJ45 plug?
To connect an RJ45 socket , you will need the following equipment:
– A multimedia RJ45 wall socket;
– Cutting pliers, wire strippers;
– A flathead screwdriver;
– A computer cable suitable for the rj45 socket;
– A cable tester for RJ45 networks.
Here are the steps to follow:
1. Cut the Ethernet cable to the desired length and strip about 5 cm of insulation to expose the strands. Remove the shielding and any plastic parts.
2. Separate the strands and arrange them according to the color order of the chosen standard (T568A or T568B). Trim the ends so they are aligned.
3. Insert the wires into the RJ45 connector, ensuring they are inserted in the correct direction. Check that the wires are fully inserted and that the colors correspond to the numbers indicated on the connector.
4. Crimp the connector to secure the wires. Repeat this process for the other end of the cable.
5. Test the cable with a wiring tester to check for any errors or loose connections.
6. Open the RJ45 wall socket and locate the terminals corresponding to the wire colors. Strip a small amount of insulation from the wires and insert them into the terminals, respecting the color code. Tighten the screws to secure the wires.
7. Close the RJ45 wall socket and fix it to the flush-mounting box with the screws provided.
8. Connect the cable to the wall socket and to the communication box or internet box.
FAQ on the color code of RJ45 sockets
What is an RJ45 socket?
An RJ45 (Registered Jack) connector is a standard type of connector for transmitting multimedia signals from devices such as computers, printers, game consoles, and telephones. This connector is universal and is currently replacing T-shaped connectors. It is often connected to the internet router via a communication box. In short, the RJ45 connector transmits information, specifically low-voltage signals, and not electrical energy (high-voltage signals) .
What is the meaning of the wire colors in an RJ45 connector?
An RJ45 cable consists of four twisted pairs of wires, each with a specific color. Each pair of wires has a precise use, depending on the information to be transmitted. Here is the RJ45 color code :
– Blue and blue-white colors for the two wires of pair 1. They are used to transmit the telephone signal;
– Orange and orange-white colors for the two wires of pair 2. They are used to share the network;
– Green and green-white colors for the two wires of pair 3. They are used to carry the computer signal;
– Brown and brown-white colors for the two wires of pair 4. They are used to carry the DTT and satellite TV signal.
What is the difference between a straight cable and a crossover cable?
A straight-through cable is a cable that uses the same wiring standard at both ends (T568A or T568B). It is used to connect a device to a switch or hub. A crossover cable is a cable that reverses pairs 1 and 3 and pairs 2 and 4 at both ends. It is used to connect two devices of the same type, such as two computers or two switches.
What are the advantages of using shielded RJ45 sockets?
Shielded RJ45 connectors have a metallic layer around the wires to protect them from electromagnetic interference. They are recommended for environments with many sources of interference, such as electrical appliances, power lines, or antennas. Shielded RJ45 connectors offer better signal quality and improved data security.
Can an RJ45 cable be used for television?
Yes, it is possible to use an RJ45 cable for television, provided the network is compatible with IPTV (Internet Protocol Television). The RJ45 cable must then be connected between the internet box and the TV decoder, or directly between the internet box and the television if the latter has an RJ45 port.
Can an RJ45 cable be used for the telephone?
Yes, it is possible to use an RJ45 cable for the telephone, provided the network is compatible with VoIP (Voice over Internet Protocol). You would then need to connect the RJ45 cable between the internet box and the IP phone, or use an RJ11/RJ45 adapter to connect an analog phone.
Conclusion
RJ45 sockets are essential connectors for enjoying a high-performance and reliable multimedia connection in your home. They allow you to transmit any type of digital signal. To wire these sockets correctly, you must respect the wire color code and the T568A or T568B wiring standards. You must also choose the type of cable best suited to your needs: straight or crossover. Finally, you must test the cable and connect the wall socket to the communication box or internet box. We hope this article has helped you understand the RJ45 socket color code and complete your installation without difficulty.
