The use of optical fiber to connect to the Internet is what we mean when we talk about fiber rollout. Telecoms would be able to offer next-generation internet services and fiber-optic network connectivity to numerous businesses thanks to the rollout of fiber. Unlike traditional copper data transmission, optical fiber data transmission uses a beam of light to send data through optical fiber glass cables. This lets data move at the speed of light and through optical fiber wires that are as thin as a human hair. Because of this, fiber broadband is the quickest way to get internet speeds of more than one gigabit per second.
