I want to install an ethernet cable and an electric cable (230V) right next to each other (same cable tube, currently 20mm in diameter, length up to 100m (i think its under 75m but i didn't measure yet)).
Here are my worries:
Even so the ethernet cable is fairly well shielded (currently CAT. 7 S/FTP, AWG 23), i'm worried that we will encounter noticeable dataloss, when using this construction at full power.
While the ethernet cable will be the only source of internet for up to 30 pc's, the electric cable has to power a majority of those (there are other electric cable already installed but not enough to power all pc's (different tubes)).
I could test it with way lower workload. I'm not sure how significant a test with 2 laptops could be.
The real test is an old-school "LAN" party, but as you might have guessed, at that time it's too late to change the installation.
Im up for suggestions (do i need further shielding, do i need another cable tube for the electric cable and if yes, how much is the minimum distance for parallel installation or will it be fine?)
