On process (did you ask your service provider?)…there is no one size fits all. It very much depends on the particular customer circumstances and building etc. It’s completely possible for them to do it all in one (long) visit, although more usually it could take several visits.
In general OR need to complete their external cabling works to bring the fibre from the nearest node (or series of nodes) from the serving exchange. Depending where you are this could typically be micro-ducted and then a new fibre bundle is blown down the micro-duct to a new node enclosure installed in the nearest footpath chamber to the premises. See photo
of mini node serving my connection being installed.
External cable from the outside mini node is then run into the building and to an enclosure where the external grade cable is transitioned to an internal grade cable. Here is mine
showing the black, jelly impregenated tube (horrible messy stuff) coming into the top left side of the enclosure. You can see the fibre tubes with their stops closing off the tubes. This photo was taken prior to the internal cable being connected to the enclosure.
From there the internal cable or blown fibre tube runs to the final equipment rack/location where a 1U Prysmian fibre splice tray (innards shown here
) again transitions to the yellow jacketed patch type leads with SC connectors that connect into the NTE - the Adva.
Just to re-iterate, with leased line service connections, they are not really standardised affairs, they are very much bespoke affairs, both in construction and execution. In any event your service provider is in the driving seat with Openreach being the guys on the tools and installing the "wires".
Edit - cleaning up typos and adding some more detail, after wine.
