Cable Installation

Hey @user_a1mqbl , Thank you for visiting our official Xfinity Forums Community support page. We greatly appreciate you taking the time to reach out with your question today. If there is protection around the cabling there should not be any issue from the rocks. 

Will burying fibre optic under gravel driveway cause a cable problem from sharp rocks?

Yes. It can't be directly buried. It will get damaged / crushed. Fiber optic cable is very delicate. It must be in a conduit pipe.
