Zeroing the FTP cable - does it make sense?

Question

Computer networks

At the enterprise, the local network is built using UTP cat.5e. The devices are connected according to the 100 Mbps and 1000 Mbps standards. In general, everything works well. But in connection with the upcoming repair, I thought about laying new cables already of the 6th category, so that in the future it would be possible to get 10 Gb / s. At the same time, I am faced with a choice: shielded or unshielded twisted pair. On the one hand, shielded is more reliable, and on the other hand, there is no information grounding at the enterprise: there is only grounding in the 220V socket and grounding of the metal frame of the building. So in case of choosing a shielded twisted pair, I will have two options:
1. Just use metal RJ-45 connectors that will make contact with the frame of the switch connectors, and the switches are already nulled, because the third pin in the 220V socket is connected to zero. But won't I get pickups on the twisted pair cable from the mains as a result? For example, during welding work.
2. Disconnect the switches from "zeroing", and ground the switching rack to the building frame. The building is pierced by load-bearing steel beams, and they are grounded with a metal strip buried in the ground. About 5 years ago, this grounding was checked by an electrical engineer with a positive conclusion.
Colleagues, what would you advise to do in order to get reliable 10-gigabit links in the future?

Answer 1

In general, what is required to drive around the enterprise in order to have 10Gbps?
For any Outlook / browsers 100 Mbps is more than enough. 1 GB or 10 GB can be thrown between routers, or servers can be connected, but they should already be nearby, in the server room.
Therefore, the question about 10 Gbps should be raised from the point of view of whether it is necessary for business?
Again, if you need to connect several specific points, it will be more reliable to throw optics - there is no need for grounding and there will be no interference, and the footage can be much larger than that of a twisted pair.
If you throw 10 Gbps to each workstation, but they will be stupidly idle, but at the same time they will consume more electricity. And even on 100 desktops, it is quite possible to notice the difference in monthly bills for electricity.

Answer 2

Those people who neglect the PUE in relation to grounding are then grounded themselves. Gloomy comrades in formal suits.
In the event of a break in the PEN conductor, you risk getting not just pickups on the equipment, but the most natural PHASE on all cable sheaths, PC cases and everything else that you have zeroed there.
So the most correct answer is for certified electricians to transfer the entire building to TN-CS, with the division of PEN into PE and N - at the entrance to the building. And all kinds of collective farms with grounding "to the frame" - there is no such thing in the PUE.

Answer 3

in addition to the above, it must be added that in case of improper grounding of the cable screen, this screen will become an antenna and pickups will be not only during welding, but always in general. in particular, the cable is grounded on one side only. if there are no problems with cables to clients, then cables between racks will have to be carefully monitored. ungrounded screen - also becomes an antenna.
