i should add, the purple tubes don't continue down to the left, they are just running the thin purples wires in the trench as they are covered with sand and filled in with the rubble.
so if someone comes along later and digs into the pavement they'll, no doubt, sever the cable.
oh, and it has been noted that the crack in the pavement just below the loose piece of purple cable on the road only appeared when they dug up the pavement, so i will be paying close attention when they come to re-tarmac the trench to see if they also fix that. if not i'll be letting them know.
I have to say, that does look like an odd way to distribute fibre cable ??. As with most things, we're all 'Football managers' thinking we know better than the guys doing the graft, but if the trench has been reinstated it does leave the cables susceptible in the future ?.
From the picture, it looks like the cables are feeding to the individual TB's (Toby Boxes - those small rectangular things at the curtilage) - then they are all taped together and, I suspect, in readiness to be pulled down the two solid ducts they've laid.
Putting my football managers hat on, it looks decidedly shoddy.
I hope I'm proven wrong.
