Extra capacity? Not been any significant new builds in the area recently, maybe it's been running close to capacity and needed some extra connections. Also noticed an electrical company were doing some major work in the road nearby a couple of months ago.
Forgot to mention in the original post, it wasn't installed by openreach/BT, saw the guy working on it, and the next day it was there.
It appears to be some sort of ‘active’ pod as it has vents .
I have a friend in Leeds with g.fast ( cab is next to his house ) and looks exactly the same as this - however where I live ( doncaster ) I have seen them used to add VDSL capacity to a cab that already had 2 normal fttc cabs
Theres a concerted effort to move end users off exchange based broadband onto NGA broadband (FTTP/FTTC) to retire the old network. That on top off the demand for home working means theres is a constant demand to increase capacity.
