What is the meaning of this RJ-45 crimp color order (router-computer) and is it correct?

Question

network hardware

Faced with the need to compress RJ-45. Having cut off part of the cable, I decided to look at the connector. Found the following order of colors as in the picture. I ask a question, because I looked through a lot of pictures with the order of colors, but I did not find it anywhere, in all the pictures one of the colors jumps in the middle. The cable was installed by an employee of the provider along with the installation of the router. I don’t understand the topic, for the first time I will be engaged in crimping an Internet cable. Replace 1 side with as it was already installed (as in the picture) or change both sides to T568B?

Answer 1

The provider hires anyone from the street according to the ad - plasterers, electricians, livestock specialists, but not network technicians . will result in poor connection quality.
If you want to avoid further questions, make a standard T568B crimp on both sides.

Answer 2

Do what you want
If only it was the same at both ends
568A
And in the picture you have A
Current colors are different
So do it as it was. Otherwise, it will not work.
You can not bother at all if the length is up to 50m (I did not test anymore)
It does not affect the speed and ping

Answer 3

Most likely the technician messed up, and he was too lazy to redo it.
Even if it's working now.
It's better to do as you wrote ".... or change both sides to T568B"
For peace of mind, so as not to guess later - these miracle glitches from crimping or ... still other reasons.

Answer 4

The cable was installed by an employee of the provider along with the installation of the router

As I understand it, you call a router that household device that combines a router + switch + access point?
In this case, in fact, the computer is stuck into the switch and the reverse crimp is not needed.
But even if it was needed, now most devices can automatically determine the type of crimp and turn on the desired mode.

Answer 5

There are 2 types, direct and cross (cross), these standards were developed a long time ago and were designed to connect devices of the same type (cross) or to connect different ones (direct). In reality, I was too young to find equipment that does not know how to auto mdi (x), this extension for network adapters allows you to auto-configure, eliminating the need to monitor the type of cable until it is crimped correctly. As a result, on at least how modern equipment you can use any type of cable, nothing will change.
Oh yes, if you figure out the "crossover" cable at both ends of the connector - we will obviously get the same straight

Answer 6

That's really true - they will pick up according to the announcements ... No, if on the other side the same crimping - nothing terrible will happen - the signal does not know what color it goes through the wires :) But if on the other side the standard or one day you decide to compress under the standard - there will be a mustache. Well, that is, the Internet will end, because this is not a crimp, but the devil knows what, in fact.

Answer 7

It’s stupid for workers to put the conductors in order, I crimp them as they are twisted in the cable. Ie white-orange with orange.
As already mentioned, the system does not care what color the wires are, as long as their structure and order are correct at both ends.

Answer 8

At a distance of a couple of meters - for modern network cards it does not matter how the twisted pair is compressed.
For longer cables, one of the T568A or T568B standards (the most common) should
be
used by reducing interference and noise problems.
