If you're where I think you are they're building a couple of resilient paths from their metro network in Slough in the general direction of High Wycombe, potentially heading to Oxford and going via Burnham and East Burnham, one of those paths presumably going through your village.
This is core Internet infrastructure rather than for any particular client. It'll appear on their long haul network map.

As for why it's going through your village it has to go through somewhere to get from A to B.
