I wanted to connect a switch to another switch at a distance of 13 meters, and because I was too lazy to make my own cable, I decided to buy a ready-made one and not bother myself. After I passed it around and connected it, the ports on the switches did not light up, and with a cable tester, I saw that wire "3" was not working. Maybe I should have checked it before installing it. Also, the thickness of this cable compared to another orange cat7 cable that I bought has a big difference. This one is very thin. I don't know if it's really cat7, but I didn't get a chance to test it.
