Many of the "next generation" fibre installers are using a new technique where they simply make a small cut 8-12 inches below the surface on the verge and bury the cable there. This reduces road damage (unless they need to change kerb sides) but can be easily disturbed as other utilities work goes on. It is far cheaper and works better in the remote regions where you go alongside smaller regional roads. If all goes well they run several routes and if someone shreds a cable on one road the others heal around. We have yet to see how it survives in the long term but the low cost usually ends up biting you on the bottom with later service bills in general?
