Is a local network in the office 10 Gigabit over copper possible?

Question

Computer networks

Actually the subject, is it possible to squeeze out a 10G (10GBASE-T (IEEE 802.3an-2006)) network over copper, category 6/6A in the realities of an office building?
The standard describes the possibility of upgrading a 1Gbe network, taking into account that a category 6 cable network has been laid.

A number of tests have been carried out. But there was a plugging, community advice is needed.
1. A category 6A cable is thrown through the ducts, communications, on both sides there is an RJ-45 connector of category 5, 30 meters of cable in total. Coordination is successful 10G is, pieces of iron have agreed. No questions.
2. We mount the same cable at one end with a cat socket. 6A , negotiation maximum 5Gb at best. The question is, what could be wrong with the outlet? We take into account that a category 6A patch cord comes from the outlet, but the rj-45 cat 5e is crimped.

10GBASE-T Thunderbolt 3 to 10 Gigabit Ethernet Adapter with NBASE-T Support
and
Optional High Speed ​​Single Port 10GBASE-T/NBASE-T Card for Synology Servers

Can there be any problems plugging the connector into a power outlet? Attachment of contacts to each other.

All cables are unshielded.

The task is essentially to make a patch panel, a switch, on the one hand, and sockets for computers with 10Gbe on board, on the other.

Category 6 cabling, but for testing, a 6A cable was thrown separately.

What can be recommendations on this issue?

Answer 1

We take into account that a category 6A patch cord comes from the outlet, but the rj-45 cat 5e is crimped.

I doubt that you managed to crimp quality. In 6A, the core is thicker and it is guaranteed not to fit into the connector 5e.

All cables are unshielded.

How so? Category 6A pairs must be shielded, the shield must be grounded.
1. As correctly written above - reduce the number of contacts. Socket - exclude.
2. Check the connection of the switch to the ground.
3. Connectors must be shielded, the shield of the connector must be connected to the shield of the cable. No shield --> no crosstalk protection --> no advertised speed. Those. it is necessary to ensure that the shield of the cable pairs is in contact with the PE (PEN) conductor of the mains. An example of a correct connector is here
4. The wire gauge must be at least 20 AWG. If you have 23-24 AWG, this is the so-called "category 6A pseudo cable", which the manufacturer positions "for patch cords". To the dump. An example of a normal cable is hereThis is the most affordable category 6A cable.
5. If, nevertheless, the cable pairs are unshielded, feel free to go to the trash. This is not 6A.
ps And please write the brand of cable used. Me for statistics.

Answer 2

Each contact is a loss, loss is a decrease in speed.

Answer 3

It's probably easier to buy a couple of media converters and let the optics
