How to crimp network cable properly in just 3 steps

There are 2 standards for crimping network cables: A and B. Depending on whether you use the network cable to connect your computer to a modem/router or to connect 2 computers together , the way to crimp the network cable will be different. Below, Quantrimang.com will guide you in detail on how to crimp the network cable for each case.

Tools needed to crimp network cables

To crimp network cables, you need the following:

• Network cable.
• Network seed, RJ 45 head ( RJ 11 head is used for desk phones, smaller in size than RJ 45).
• Network crimping pliers (you can buy at any computer store, price about 150k)
• Computer, Switch or Modem has network to test after clicking.

Standard A and standard B in network cable crimping

Currently, there are many documents and websites on the internet talking about these two standards, with the names T568A (standard A) and T568B (standard B). In theory, to connect two devices together (for example, computer - computer, switch - switch...), you need to press the cross standard, and to connect different types of devices, you need to press the straight standard.

• Standard A: Green white - Green - Orange white - Blue - Blue white - Orange - Brown white - Brown (a bit confusing, hard to remember).
• Standard B: Orange white - Orange - Green white - Blue - Blue white - Green - Brown white - Brown (easier to remember than the above).
• Straight standard (both ends are pressed according to standard A, or both ends are pressed according to standard B), to connect two different types of devices together such as computer - switch, switch - router.
• Crossover standard (1 end of the wire is crimped according to standard A, the other end is B or vice versa), used to connect two devices of the same type together. When we need to connect two computers with a network cable, we also use this standard.

Network cable crimping steps

Step 1:

Now, let's get to work. First, cut a piece of network cable, the length depends on the purpose of use, then use network crimping pliers to cut a piece of the outer shell, about 2 - 3 cm short, to expose the entire core of the network cable (there are 8 colors):

Step 2:

Then, try to smooth the wires evenly and straight (because the straighter the easier it is to crimp). Use crimping pliers to cut off the concave end of the wire core, take the end of the wire and insert it into the core after cutting it straight as shown below:

Step 3:

The final step is to use the network crimping tool to clamp the plastic head of the network bead, press firmly (depending on the type of network head, you will hear a small cracking sound or not):

Step 4: Plug 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.

Network cable crimping is the most basic job of WebTech360 . Network cable crimping requires the most basic skills in the system of learning and working in the system administration industry. Why is that? Some simple questions are asked as follows:

• What do you need to connect two computers together?
• What does a computer need to connect to an Access Point, Router, Switch...?
• Why are there two network cable standards A and B? How are they different?

How to crimp network cable without pliers

Sometimes you can’t find a pair of crimping pliers and the conditions don’t allow you to move the network cable. So how can we crimp the network cable without crimping pliers?

WebTech360 would like to send you instructions on how to crimp network cables without pliers to help you fix difficult situations.

Step 1 : Things to prepare:

• Tool for cutting network cable sheath
• Flat Head Screwdriver
• Network cables and network beads

Step 2 : Cut the network cable's sheath and arrange the network cable according to the standard you need to crimp the wire. Next, cut the end of the network cable flat and tuck it neatly into the network bead as if you had pliers.

Step 3 : Use a double-sided screwdriver to block the end of the wire to keep it from moving in and out.

Step 4 : Use a screwdriver to press each copper leg of the network chip so that it is embedded in the network cable for the purpose of fixing and connecting the signal. You should do it gently and firmly to avoid damaging the copper leg.

Step 5 : Check each pin to see if it is plugged in tightly, then try plugging it in to see if there is a connection.

It is obviously difficult to do anything without a special tool, and crimping network cables is no exception. Crimping network cables without pliers is obviously more complicated than using pliers, but it can be useful when needed.

Above is the entire process of crimping the network cable. If you have all the tools, you can completely crimp the network cable yourself or crimp it for your friends. In addition, you can refer to how to fix the error of the network being marked with a yellow exclamation mark when plugging in the network cable or using wifi.

Good luck!
