How to connect connector to ethernet cable?

Ethernet cables are widely used to connect devices to local area networks (LAN) or the internet. If you need to connect a connector to an Ethernet cable, follow these simple steps to ensure a reliable and efficient connection.

What tools will I need?

To connect a connector to an Ethernet cable, you will need the following tools:
– Ethernet cable
– Ethernet connector (RJ-45)
– Wire cutters/strippers
– Crimping tool

Step 1: Strip the outer sheath

– Begin by carefully removing about 2 inches (5 cm) of the outer sheath from the Ethernet cable. Be cautious not to damage the inner wires while stripping the sheath.


Step 2: Untwist the wires

– Once the outer sheath is removed, you will find four pairs of twisted wires inside the cable. Gently untwist these wires to prepare for the connection process.

Step 3: Arrange the wires

– Sort the wires according to the T568B or T568A standard wiring scheme. Make sure to align the colors of the wires in the correct order of:
T568B: Orange-white, Orange, Green-white, Blue, Blue-white, Green, Brown-white, Brown
T568A: Green-white, Green, Orange-white, Blue, Blue-white, Orange, Brown-white, Brown

Step 4: Trim and align the wires

– Using wire cutters, trim the wires evenly so that they are about 1/2 inch (1.3 cm) long. Ensure that they are aligned in a straight line ready for insertion into the connector.

Step 5: Insert the wires into the connector

– Carefully insert the wires into the RJ-45 connector, making sure that each wire corresponds to the correct pin location. Push them as far as they will go to ensure a secure connection.

Step 6: Crimp the connector

– Take the crimping tool and carefully apply pressure to the connector to crimp it onto the wires. Make sure the tool is properly aligned with the connector to avoid any damage to the plastic housing.

Step 7: Verify the connection

– Once you have crimped the connector, give the cable a gentle tug to ensure it is securely attached. You can also use a cable tester or connect it to a device to verify that the connection is working correctly.

Now you have successfully connected a connector to an Ethernet cable and are ready to use it for your networking needs! Remember to repeat the process for both ends of the cable to establish a complete connection.


Can I use any type of Ethernet cable?

No, it is important to use the correct type of Ethernet cable, such as Cat 5e, Cat 6, or Cat 6a, depending on your network requirements.

What happens if I connect the wires in the wrong order?

If the wires are not correctly aligned according to the T568B or T568A standard, the connection may not work, and you may need to re-crimp the connector.

Is it necessary to strip the outer sheath?

Yes, stripping the outer sheath is crucial to expose the inner wires and allow them to make proper contact with the connector.

Can I use a different tool if I don’t have a crimping tool?

While a crimping tool is recommended for a reliable connection, you may be able to use a combination of pliers and connectors with built-in crimps. However, this method may not yield the same level of quality and durability.

What if the cables are too short after crimping?

It is essential to measure the required cable length before stripping and crimping. If the cables become too short, you may need to start again with a new Ethernet cable.

Can I reuse a connector if I make a mistake?

No, once a connector has been crimped, it cannot be reused as it permanently binds the wires to the connector.

What if I accidentally damage a wire while stripping the sheath?

If a wire is damaged during the process, you may need to start over with a new Ethernet cable to ensure a proper connection.

Can I use electrical tape instead of crimping?

Using electrical tape to secure the wires is not recommended. It does not provide proper connection reliability and can result in signal loss or interference.

How can I verify the connection’s speed and performance?

To verify the speed and performance of an Ethernet connection, you can use a network speed test tool or check the link speed in your device’s network settings.

Can I connect connectors to shielded Ethernet cables?

Yes, the process is similar, but you need to ensure the shield is correctly connected to the connector’s housing to maintain proper shielding and minimize interference.

Is it possible to connect an Ethernet cable without using connectors?

No, connectors are necessary to establish a secure and proper connection with Ethernet cables.
