I've searched previous threads before posting, watched videos, talked to grok and I get so much conflicting info.

I have two problems to solve. One is an external cable run from downstairs, up to roof, over roof and into a rear bedroom/office. When the cable(s) come into the office, they will pass an 8kw heat pump. At a guess it's 30-35 meters (accounting for cable routing for aesthetics) Research points me towards Cat6a STP external for this. I want to future proof for 10gb speeds.

The other is an internal run, office/bedroom to landing to connect to a unifu U7 ceiling mounted downstairs. 5 meters max. The floor run has loads of 240v electrical cables running though, I can't avoid cable being close/crossing them.

I'm hoping to use the external cable needed for the first point internally (to save buying two cables).

Reading into shielding means I know (sort of) the complications this now brings with bonding/grounding.

So, I guess my questions are:

  1. Is cat 6a STP the right call or not?
  2. Any issue with the external cable internally
  3. Assuming run these cables into a patch panel and then ground it. All should be ok?

Was thinking this: https://amzn.eu/d/11aVucI (patch panel) And using it with this: https://amzn.eu/d/11aVucI (earth lead) And this: https://amzn.eu/d/11aVucI (grounding plug)

Will this work? Does it make sense to do?

Thankyou
