Ethernet Cable Color Coding- What You Need to Know for Router Setup

In today’s technology-centric age, having a reliable Internet connection is critical. The router is a fundamental component in enabling this connection, and knowing how to set it up correctly is crucial for a seamless online experience. One of the key aspects is understanding the color coding of Ethernet cables, which is necessary to properly connect devices.

Mystery of color coding

Ethernet cables usually use eight wire cores, each of which is wrapped in a colored insulation layer. These colors are not chosen arbitrarily, but follow accepted standards to indicate the type and purpose of the cable.

Orange (TX+) : Data is transferred from the device to the switch or router.

Orange white (TX-) : Data is transferred from the device to the switch or router.

Green (RX+) : Data is received from a switch or router.

Green White (RX-) : Data is received from the switch or router.

Blue (none) : detects and corrects transmission errors.

Blue and white (none) : Standby.

Brown and brown white: Used for gigabit Ethernet.

Crossed and uncrossed cables

Another important aspect of understanding Ethernet cable color coding is the distinction between crossed and non-crossed cables.

Non-crossover cable: suitable for connecting devices to switches or routers. The transmit and receive pairs are arranged in the same order at both ends of the cable.

Cross cable: Used to directly connect two devices, such as two computers. The sending and receiving pairs are exchanged at one end of the cable.

The art of proper connection

For home networks, properly connected devices are critical. Follow these steps to ensure a seamless connection:

1. Determine the cable type (cross or non-cross).

2. Connect one end of the cable to the Ethernet port of the device.

3. Connect the other end of the cable to the Ethernet port on the switch or router.

4. Check the indicator on the device to ensure that the connection is established.

By understanding the color coding of Ethernet cables, you can easily set up your router and enjoy a stable Internet connection. Don’t let the rainbow hues of cables confuse you, master their mysteries and bring your network to life.
