Can optical fiber replace traditional cable?

In the short term, optical cables are mainly used in trunk lines or broadband with large bandwidth. However, most traditional cables are still used for lines to users and telephone networks from branch computer rooms to users' homes. Now the broadband network is developing towards the optical network, that is, all broadband networks+telephones+televisions use a leather cable to enter the home, thus replacing several cables that used to enter the home. And there is already a fiber-optic network card. It's just that ordinary home users with high cost haven't started to promote it yet.

It is predicted that the future will be dominated by wireless networks (microwave networks, etc.). At that time, all power supplies, signals and so on will be wireless. There are no more telephone poles and cables in the street.
