I suspect your main problem would be the finances.
Or local Gigaclear network connects to a manhole with Vodafone written on the cover. I suspect that several fibres are used but I don't actually know. Gigaclear started the installation when about 200 out of 600 premises had signed up.
Gigaclear employed two contractors. Wingnut who dug hoes in the road and laid the cables, and Boxcom who completed the joints, installed and I think now manage the equipment in the cabinets. Terminating (joining) fibres is a slow process. It took two men all week to terminate the lines on my local cabinet. I would guess about 200 lines. Each fibre in the cable in the road is connected to a lead with a plug on the end of it. The plug then fits into the cabinet hardware.
