Yeah, a bunch of cabinets connect to one of
these which usually lives in a pit underground.
From there these nodes have a fibre run back to a local exchange.
It's like a trunk and branches arrangement, a fibre trunk which branches off into these which in turn branch off to feed individual cabinets and/or FTTP splitters.
The node that feeds my local cabinet is actually about 1.2km away; as you can imagine given the distance it feeds several cabinets in this area of the city, each with its own fibre route and microduct back to that node where all the fibres are, well, aggregated together into a single high count cable back to our local Hunslet exchange.
