How to crimp network cables correctly in just 3 steps.

Network cables come in two standards, A and B. The method of crimping depends on whether you're connecting a computer to a modem/router or two computers to each other . Below, TipsMake.com will guide you through the detailed process of crimping a network cable for each case.

 

Tools needed for crimping network cables.

To crimp a network cable, you will need the following:

1. Network cable.
2. Network connector, RJ45 plug ( RJ11 plug is used for landline phones, and is smaller than RJ45).
3. Network crimping tool (you can buy this at any computer store, it costs around 150,000 VND)
4. After pressing the button, make sure your computer, switch, or modem has a network connection for testing.

 

 

Standards A and B in network cable crimping

Currently, there are many documents and websites online discussing these two standards, known as T568A (standard A) and T568B (standard B). Theoretically, to connect two devices together (e.g., computer to computer, switch to switch.), you should use a crossover cable, while connecting different types of devices requires a straight cable.

1. Standard A: White-green - Green - White-orange - Blue - White-blue - Orange - White-brown - Brown (a bit complicated, hard to remember).
2. Standard B: White-orange - Orange - White-green - Blue - White-blue - Green - White-brown - Brown (easier to remember than the above).
3. Straight connector (both ends crimped according to standard A, or both ends crimped according to standard B), used to connect two different types of devices together, such as a computer and a switch, or a switch and a router.
4. Crossover standard (one end crimped to standard A, the other to standard B or vice versa) is used to connect two devices of the same type. This standard is also used when connecting two computers using a network cable.

Steps for crimping network cables

Step 1:

Okay, let's get started. First, cut a length of network cable, depending on your needs. Then, using a crimping tool, cut off a short section of the outer sheath, about 2-3 cm long, to expose the entire core of the network cable (there are 8 colors):

Step 2:

Next, try to smooth the wires evenly and straight (the straighter they are, the easier they are to crimp). Use a network crimping tool to cut off any uneven ends of the wires, then take the connector and insert it into the straightened wire core as shown in the image below:

Step 3:

The final step is to use crimping pliers to grip the plastic head of the network connector and press firmly (depending on the type of connector, you may or may not hear a small clicking sound).

 

Step 4: Test by plugging one end of the cable into the computer and the other end into the switch or modem to see if the computer has a network connection.

Crimping network cables is the most basic task in network administration . This requires fundamental skills learned and practiced within the system administration field. Why is that? A few simple questions can be asked:

1. What do I need to connect two computers together?
2. What components are needed for a computer to connect to an Access Point, Router, Switch, etc.?
3. Why are there two network cable standards, A and B? How do they differ?

How to crimp network cables without pliers

Sometimes you can't find a network cable crimping tool, and the situation doesn't allow you to move the network cable. So how do we crimp a network cable without crimping tools?

TipsMake.com would like to share with you a guide on crimping network cables without pliers to help you overcome difficult situations.

Step 1 : Things to prepare:

1. Tools for cutting the insulation off network cables.
2. Flathead screwdriver
3. Network cables and connectors

Step 2 : Cut the outer sheath of the network cable and then arrange the cables according to the standard you need to crimp. Next, trim the ends of the cables flat and neatly insert them into the connectors, just like you would with crimping pliers.

Step 3 : Use a flathead screwdriver to block the end of the wire to prevent it from moving in and out.

Step 4 : Use a screwdriver to press each copper pin of the network connector into the network cable to secure and connect the signal. You should do this gently and firmly to avoid damaging the copper pins.

Step 5 : Check each pin to ensure it's securely plugged in, then test to see if a connection is established.

Obviously, it's difficult to do anything without specialized tools, and crimping network cables is no exception. Crimping a network cable without pliers is clearly more complicated than using pliers, but it can be useful when needed.

Above is the entire process of crimping a network cable. If you have the right tools, you can completely crimp a network cable yourself or help a friend crimp one. Additionally, you can refer to how to fix the yellow exclamation mark error when plugging in a network cable or using Wi-Fi.

Good luck!
