Ethernet cables are the most common cables used to connect computers to networks and the internet. While they are relatively easy to use, it is important to know how to connect them properly to ensure a reliable connection. If you are not sure how to connect an Ethernet cable, don’t worry. This article will provide you with step-by-step instructions on how to do it. However, if you are not comfortable working with electrical cables, it is best to consult a qualified electrician.
First, you will need to gather the necessary materials. These include an Ethernet cable, a crimping tool, and RJ-45 connectors. You can find these items at most hardware stores or online. Once you have all of your materials, you can begin the process of connecting the Ethernet cable. Start by cutting the Ethernet cable to the desired length. The cable should be long enough to reach from the computer to the network jack, but not so long that it is coiled up or tangled. Next, strip the outer jacket of the cable about 2 inches from the end. Be careful not to cut the inner wires.
After you have stripped the outer jacket, you will see eight individual wires. These wires are color-coded according to the TIA/EIA-568B standard. The colors are: white/orange, orange, white/green, blue, white/blue, green, white/brown, and brown. The order of the wires is important, so be sure to follow the standard. Once you have arranged the wires in the correct order, you can insert them into the RJ-45 connector. The connector has a small tab on one end that must be pressed down. Push the wires into the connector until they click into place. Make sure that the wires are all the way in and that the tab is down.
How To Connect Ethernet Cable Connector
Identifying the Ethernet Cable and Connector
Ethernet cables are a crucial part of any computer network, connecting devices such as computers, routers, and switches. The most common type of Ethernet cable is the RJ45, which is a type of twisted pair cable with eight wires. The RJ45 connector is a plastic housing that contains eight metal pins, which are used to connect the wires to the device.
To identify an Ethernet cable, look for the following characteristics:
1. The cable should be round and about the thickness of a pen or pencil.
2. The cable should have a plastic connector at each end.
3. The plastic connector should have eight metal pins.
4. The cable should be labeled with the type of Ethernet cable it is.
The following table provides more information about the different types of Ethernet cables:
| Ethernet Cable Type | Speed | Maximum Length |
|---|---|---|
| Cat5 | 100 Mbps | 100 meters |
| Cat5e | 1 Gbps | 100 meters |
| Cat6 | 10 Gbps | 100 meters |
| Cat6a | 10 Gbps | 100 meters |
| Cat7 | 10 Gbps | 100 meters |
| Cat7a | 10 Gbps | 100 meters |
Preparing the Ethernet Cable for Termination
Preparing the Ethernet cable for termination is a crucial step in ensuring a secure and reliable connection. Follow these steps carefully to ensure successful cable termination:
- Gather Necessary Tools: You will need a cable stripper with adjustable stripping depth, wire cutter, and RJ45 connectors.
- Cut the Cable to Length: Measure and cut the Ethernet cable to the desired length, considering the span between the termination points and any necessary slack. Avoid cutting the cable too short, as there should be enough length for termination and future servicing.
- Strip the Cable Jacket: Using the cable stripper, carefully remove approximately 2 inches (5 cm) of the outer jacket from the cable end, exposing the four twisted pairs of wires inside.
- Straighten and Untwist the Wires: Gently pull the wires apart and straighten them out. Use wire cutters to trim any uneven wire ends, ensuring they are all flush with the cable jacket edge.
Untwisting the Wires
Untwisting the wires is a critical step, as it allows for proper insertion into the RJ45 connector and subsequent termination. Follow these guidelines:
- Avoid untwisting the wires excessively, as this can weaken their integrity.
- Maintain the specified color code for the wire pairs. For T568A wiring scheme, the colors should be arranged as follows:
- Untwist approximately 1 inch (2.5 cm) of each wire pair, leaving the rest intact for better signal transmission.
| Pair | Colors |
|---|---|
| 1 | Orange/White, Orange |
| 2 | Green/White, Blue |
| 3 | Blue/White, Green |
| 4 | Brown/White, Brown |
Installing the RJ-45 Connector on the Cable
1. Straighten the wires and cut them evenly. About 1/2 inch (1.27 cm) of bare wire should extend from the end of the connector.
2. Arrange the wires in the correct order. The order, from left to right, is:
| TIA-568A | TIA-568B |
|---|---|
| Green | Green |
| Green/White | Green/White |
| Orange | Orange |
| Orange/White | Orange/White |
