Whether it's crimping crossed cables or crimping straight cables, IT Support and HelpDesk personnel must have a thorough understanding of this skill because replacing network cables is a very common task for IT professionals. Knowing how to crimp crossed and straight cables correctly allows for quick replacement without errors. If network cables are crimped incorrectly, there will be no signal, leading to the need for re-crimping, resulting in wasted time.
Crimping Crossed and Straight Network Cables
At present, there are two slightly different arrangements for crimping both crossed and straight network cables, including T568A and T568B. You can use either of these types of cables for crimping crossed or straight network cables.
Crossed Network Cable Crimping Diagram
First, let's take a look at the crossed network cable crimping diagram to understand how to crimp crossed network cables and what the colors represent.
Straight Network Cable Crimping Diagram
In the straight network cable crimping diagram, users only need to pay attention to the position of the wire colors, as there isn't much difference in the colors of the 8 wires. This is the easiest crimping type for beginners at the moment.
Should You Crimp Crossed or Straight Cables?
Basically, in the past, we used to use the crossed network cable standard for connecting switch-switch or switch-hub, but at present, all switches have auto-sensing and switching capabilities. So, whether you crimp crossed or straight cables, it doesn't matter.
Current Standard Network Cable Crimping Method
Standard Equipment Needed:
- RJ45 standard crimping tool, commonly used and priced at around 80,000 Vietnamese dong.
- Specialized wire cutting knife, can be used as a replacement for the knife blade of the crimping tool.
- Most common RJ45 crimping plugs available today, you can find them in any computer accessory store.
- Of course, 8-strand black network cable.
- Network cable connection testing device (may not be necessary)
Because both crimping crossed and straight network cables have their own instructions, differing only in color as we've differentiated above, the following instructions apply to both crimping crossed and straight network cables today.
Step 1: The first step in crimping crossed or straight network cables is to strip the outer sheath. The length can be long or short depending on your preference, but Mytour recommends cutting a section of about 2 cm if you're not yet proficient.
Step 2: Untangle the 8 strands of wire and arrange their colors according to the T568B standard.
Step 3: Then, bundle the wires together in the correct color sequence as mentioned above. Use wire cutters here to ensure all wire ends have the same color.
Step 4: Next, proceed to insert the network cable into the RJ45 plug according to the standard we've analyzed above. Then use a crimping tool to crimp and secure it onto the wire.
Note: During the crimping process, all wires must be fully inserted. A single missing wire will result in a failed connection.
Thus, we have completed the crimping of crossed and straight network cables. The standard crimping method described above will provide you with the most accurate crimping and the most stable connection for your network system. This method applies to crimping 8-color network cables, which are currently the most common, rather than the 4-strand type. With 8-color network crimping, it will be easier for you to distinguish its positions, whether you are crimping crossed or straight cables.
