So, I put an #Ethernet cable under a floor mat, and the friction tore the outer casing apart!
Surprisingly, the inner casings on the conductors inside are still intact, but the destruction of the outer casing has untwisted them. They're just straight wires now.
Also surprisingly, despite the cable now being majorly out of spec, it still carries 100Mbps without incident. Now that's some quality electrical engineering.
Anyway, I got a rubber floor conduit to protect the untwisted pairs.
If you're surprised by that have a look at VDSL vectoring and people replacing the 1 pair unshielded wire with a wet string.
A wet string is somehow conductive enough to carry VDSL signals??? 🤯
yep, and it wasn't even that slow either.
I only find the ADSL one that predated the VDSL experiments via google right now. But I've seen the VDSL ones on social media shortly after by someone else. (I think it was Twitter, so maybe they deleted their account or it is just not that well discoverable through google...)
