I am not the first one who crimped the RJ-45 connector under a microscope. But I think that you are wondering which is better to crimp an RJ-45 screwdriver or crimper?

In the previous video, I showed how you can triple the speed of mobile Internet using the MikroTik LHG LTE6 kit antenna on the outskirts of the city, in the suburbs and even in the forest. The video will help you choose the right antenna. In addition, I wanted to show that it is better to crimp an RJ-45 screwdriver or a crimper on a network cable. But I decided to complicate the task and crimped the RJ-45 connector under a microscope. Let's start with the RJ45 connector. There are eight pilot holes inside. By inserting wires into them, it is difficult to disturb the order. In addition, the connector is transparent. Thanks to this, every posting that goes along its own channel is visible. When the wires hit the wall, they can be crimped. The crimper clamps the insulation with this latch and simultaneously presses on all the plates, piercing the insulation with them and pressing the wires until the plates rest against the stopper. The limiter prevents the connector from breaking.
In the video, we will check everything in practice and find out what is better for crimping an RJ-45 screwdriver or a crimper network cable.
For crimping with a screwdriver with our own hands, we need a network cable of the required size for four twisted pairs and RJ45 connectors. You will also need any sharp knife, scissors and a screwdriver with a slot a little more than a millimeter thick. A thicker screwdriver can break the baffles between the plates.
We remove the insulation from the cable so as not to damage the wires, and we do it with a margin. Longer wires are easier to straighten. We will untwist all four twisted pairs and straighten each wire.
For the MikroTik antenna and to connect it to a computer or other distributing router, a direct crimp order is used. The wires will run in the following order. White-orange, orange.
White-green, blue. White-blue green. White-brown, brown. Let's group the wires with our own hands in this sequence and smooth them out properly. The excess needs to be cut off. We measure twelve and fourteen millimeters from the edge of the insulation by eye. And cut off the excess evenly.
Now we take the connector. Turn it with the tongue down and insert the wires all the way. Like this. The colors seem to be all right ... You can see everything from the end too. To press with a screwdriver and not break anything, you need some kind of stop.
The cooling radiator caught my eye and it fit perfectly. Now take a screwdriver and slowly press each plate in. The screwdriver should be good. With licked slots, it can slip off and break the partition.
Let's look under the microscope at the connector molded with a screwdriver and a crimper. In general, there is nothing to complain about. I press it well. But still, one plate of the connector, which was manually crimped, is a little undersqueezed. Let's squeeze it with a crimper. RJ-45 connector crimped under a microscope
It will not be superfluous to ring the cable to make sure everything is done correctly. I will do it with a multimeter, but someone who does this often can order an inexpensive device that performs a check in a matter of seconds.
What else would I like to say ...
If you want to make a network between two computers with your own hands, then you need to do not direct, but cross crimp
There are also network cables consisting of two twisted pairs. This twisted pair is now on the screen, the main thing is to get the green wire into the sixth socket, and they are crimped in the same way. And consider. The MikroTik LHG LTE6 kit antenna requires an eight-core cable. These are four twisted pairs. Additional conductors supply power to the router to the antenna. It still doesn't hurt to know that network cables are divided by color. Black for outdoor use. Light ones are used indoors.
For CAT5e cable, the data transmission rate when using 4 pairs reaches 1000 Mbps at a frequency of 125 MHz. And the throughput of a twisted pair of the seventh category is up to 10Gbps. It also consists of four twisted pairs. True, each twisted pair of such a cable is shielded and it is more expensive.
Who doubts the veracity of my words, we can discuss this topic in the comments.
In the next video, we will finally assemble with our own hands an unusual chair floating in the air or a stool - until I decided.
And this is all dear friends. Now you know how a four-wire twisted pair differs from an eight-wire twisted pair. And also you know what is better to crimp an RJ-45 screwdriver or crimper. For this purpose, I pressed the RJ-45 connector under a microscope.
