With the fiber optics being offered for my old small house [60m² build in 1990], I wanted to avoid using Wi-Fi and use an ethernet connection. The length between where the fiber outlet will be and my desk is 20 meters. I wanted to have cat5e Solid UTP to avoid all this business about grounding, plus I do not install the ethernet cable near the electrical cable, but the seller refused to sell me cat5e for a custom length of 20 meters and only offered custom length for a cat6a U/FTP Solid cable....
I also ordered 2 keystone jacks rated for SFTP and now I do not know how to ground all those things. here is the simple explanation of my ''network''
optical outlet [in the lounge]
=>ONT [in the lounge]
=>router given by the ISP [in the lounge]
=>little patch cable cat5e [shielded?] [in the lounge]
=>female rj45 outlet in the wall with SFTP keystone jacks [in the lounge]
=>U/FTP cat6a Solid cable of length 20 meters going into the attic from the lounge to my office
=>female rj45 outlet in the wall with SFTP keystone jacks [in the office]
=>little cat6a patch cable [shielded?] [in my office]
=>my computer [laptop from 2019] [in my office]
As you see I do not have any patch panel with its cable being attached to whatever makes the ground in proper installations.
If I cannot ground those things, what can I do decrease the risk of interference (risk is small since my house is very small and I do not put the ethernet cable near big electrical devices)?
Can the router for end consumer by the ISP be grounded? If so, how do I check it is grounded?
if the router of the ISP is not grounded, can I put a device [a switch?] on my network which does the grounding?
