Rj45 Colour Code Made Easy: A Step-by-Step Wiring Guide

Absolutely! Let's demystify the world of RJ45 colour codes with this step-by-step wiring guide that will make you feel like a networking pro in no time.

Step 1: Gather Your Tools

Before we dive in, make sure you have the following tools handy

RJ45 connectors

RJ45 connectors and Ethernet cables are fundamental components of modern networking, allowing data to be transmitted over local area networks (LANs) and wide area networks (WANs). They play a crucial role in connecting devices and enabling communication in both home and business environments.

RJ45 connectors, also known as Registered Jack 45 connectors, are a common type of connector used in networking and telecommunications. They are most commonly associated with Ethernet networks, where they are used to connect computers, switches, routers, and other networking devices. 

Ethernet cable

  • Cat5e: Supports up to 1 Gbps (Gigabit per second) and is suitable for most home and small business networks.
  • Cat6: Supports up to 10 Gbps and is commonly used in commercial and enterprise environments where higher speeds are required.
  • Cat6a: Also supports up to 10 Gbps but offers improved performance and reduced crosstalk compared to Cat6 cables.
  •  Cat7: Supports up to 10 Gbps and provides better shielding against interference, making it suitable for demanding applications

Ethernet cables are a type of networking cable commonly used to connect devices within a local area network (LAN) or to provide internet connectivity to computers, routers, switches, and other networked devices. These cables are an essential part of wired networking and come in various categories, each with specific capabilities

Ethernet cables are a reliable and widely used method for establishing wired network connections. They are crucial for creating stable and high-speed networks in homes, offices, data centers, and various industrial settings. The choice of Ethernet cable category depends on the specific network requirements and the desired data transmission speeds.

Crimping tool

A crimping tool, also known as a crimp tool or crimping pliers, is a handheld tool used to attach connectors or terminals to the ends of electrical or network cables. Crimping is a common method for creating secure and reliable electrical connections in a wide range of applications

Cable stripper

A cable stripper is a hand tool or a specialized device used to remove the outer insulation or sheathing from electrical cables or wires. It is an essential tool for electricians, network technicians, and anyone working with cables or wires. Cable strippers are designed to make the process of exposing the inner conductors of a cable safe and efficient.

Ethernet cable tester

An Ethernet cable tester is a device used to check the functionality and quality of Ethernet cables. Ethernet cables are commonly used in networking to connect computers, routers, switches, and other devices to create local area networks (LANs) and connect to the internet. Ethernet cable testers are invaluable tools for IT professionals, network administrators, and anyone working with network cabling

Step 2: Strip the Cable

Carefully strip about 1.5 inches (3-4 cm) of the outer insulation from the end of your Ethernet cable using the cable stripper. This will expose the twisted pairs inside.

Step 3: Untwist the Pairs

Inside the link, you’ll track down four bent sets of wires. Gently untwist them while maintaining the pair’s twist as close to the end as possible.

Step 4: Arrange the Wires

Organize the wires in the accompanying request, from left to right

  1. White-Orange
  2. Orange
  3. White-Green
  4. Blue
  5. White-Blue
  6. Green
  7. White-Brown
  8. Brown

Step 5: Trim and Align

Using your fingers or wire cutters, trim any excess wires so that they are all the same length and neatly aligned.

Step 6: Insert Wires into RJ45 Connector

Gently insert the aligned wires into the RJ45 connector, ensuring that they reach the end of the connector.

Step 7: Crimp the Connector

Place the connector into your crimping tool and squeeze it firmly to secure the wires in place. You’ll feel a satisfying click when it’s properly crimped.

Step 8: Inspect Your Work

Give your newly crimped connector a thorough inspection to ensure that all wires are properly seated, and there are no stray wires or shorts.

Step 9: Repeat on the Other End

Repeat steps 2 through 8 on the other end of your Ethernet cable to maintain consistency

Step 10: Test Your Cable

If you have an Ethernet cable tester, use it to check that your cable is wired correctly and free of any faults. It’s a great way to confirm that your hard work has paid off

Type of RJ45 Colour Code

Certainly! RJ45 color codes refer to the standard color-coding scheme used for Ethernet cables with RJ45 connectors. These color codes help ensure that the wires inside the cable are connected consistently to facilitate proper data transmission. There are two common types of RJ45 color codes:

1. T568A Wiring:

  • Pin 1 (White-Green)
  • Pin 2 (Green)
  • Pin 3 (White-Orange)
  • Pin 4 (Blue)
  • Pin 5 (White-Blue)
  • Pin 6 (Orange)
  • Pin 7 (White-Brown)
  • Pin 8 (Brown)

2. T568B Wiring:

  • Pin 1 (White-Orange)
  • Pin 2 (Orange)
  • Pin 3 (White-Green)
  • Pin 4 (Blue)
  • Pin 5 (White-Blue)
  • Pin 6 (Green)
  • Pin 7 (White-Brown)
  • Pin 8 (Brown)
