We have a remote outbuilding which needs a wired network and
running the SWA Cat 6a shielded solid core looks like the right
choice for 'bury and forget it for many years', but some
installation questions come up as this is a relatively novel
project for me:
Is this the right cable appropriate for direct burial (soft
earth, ~6 inches down) or does it need a conduit? (Product
14782)
What is the minimum curvature for routing the cable? (Bend
radius about 8x12.2mm so about 10cm?)
Is there any feasible option for routing to faceplate or is the
sensible approach to terminate at inline junction box then regular
Cat6a to faceplate?
Any issues grounding the drain wire through copper plumbing
already used for electrical grounding in the outbuilding or must
the grounding be completely independent of the rest of the
electrical circuits on which the networked devices will run?
There's already independent power laid to the building already
so the network link just needs to be resilient and reliable for
carrying data signals, no PoE or similar.

If I were you I would put in a 40mm cable duct and just run duct
grade Cat6. Cat6A is absolute overkill for the job and you have no
requirement here for shielded cable. You may have more problems
with shielded than unshielded, also the shielding should not be
grounded to an electrical ground, it is grounded through equipment
connected to mains or a patch panel. In the future if you need to
go beyond 1Gigabit networking then you could pull through a fibre
too. I've seen installs that have just run vanilla Cat5e over 90m,
and it's in bad shape and badly installed and still tests a pass at
