I am running a Cat 5 cable close to a 6mm SWA cable over a 15M run.

Is it worth using shielded Cat 5?

It's supplying a garden studio so there will be the occasional electric
fire / kettle kicking in and out.

At 15m and if trenching allowed, I'd just bury some hosepipe a minimum of
12" (preferably 24") away from the armoured & thread cat6 through it. The
pipe lets you pull another through if you need to (include a draw wire!).
You should be able to use gigabit ethernet over that - something that wifi
can only dream about. It's simpler and cheaper than fibre. OTOH, if you
can't allow that sort of spacing, then fibre is really the only answer.


Why would you need to be 2 foot away from a cable thats very effectively
shielded?.

CAT 5 is a very good balanced transmission system and is inherently good
at rejecting other electric fields, so why so far away?..


I'm running some cat6 alongside mains cable in places - obviously, it's
the easiest route to follow through a house. I did read that it's not
advisable, but thought I'd give it a try and so far, so good. Do you
think that ethernet-next-to-mains-equals-disaster is an urban myth?
