Twisted pair FTP 5e why does not start 1Gb / s?

Question

Cables and wires

I bought it from VCOM, crimped the wire for a couple of meters for the test, but it only connects to 100Mb / s, is it because of the foil insulation or do I need to take category 6 for 1Gb / s?

Answer 1

1 you need to crimp all the cores, the foil is a screen, it is also used by a connector with a screen
2 check if the network cards support gigabit
3 check if you can manually set gigabit.
4 copper or copper-plated conductors, and what section they have.

Answer 2

Unfortunately, you have chosen the most shitty cable, besides it is aluminum, buy a normal coil with thick copper.

Answer 3

On questions:
- you don’t need to take the sixth category, everything works fine on 5e.
- the screen does not play a special role, it does not need to be connected if the RJ-45 connector does not allow it;
- the cable is shit, take neomax for example, but even on it it should start at two meters.
I suspect that:
- they squeezed it with a shit tool and didn't finish it;
- conductors are not completely filled into the connector;
- there was a spacing, the signals of different pairs in the connector were mixed up - this is the most important thing, physically the cable will be normal, but it will not work normally, since there will be pickups between the pairs.
What to do:
- once again fill in the crimp and squeeze;
- absolutely ALL conductors must be pressed against the end of the connector and be of the same length, cutting before filling the conductors into the connector is performed in ONE action.
- carefully check the marking of the conductors in the connector.

Answer 4

maybe the equipment only supports 100 ku)
