Explanation: 

Detailed explanation-1: -Also known as optic cables or optical fiber cables, they transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables.

Detailed explanation-2: -A fiber-optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred.

Detailed explanation-3: -Internet and Local Area Networks (LANs) Both LAN and high-speed internet use multimode fiber optic cable.

Detailed explanation-4: -Fiber-optic cables transmit data via fast-traveling pulses of light. Another layer of glass, called “cladding, ” is wrapped around the central fiber and causes light to repeatedly bounce off the walls of the cable rather than leak out at the edges, enabling the single to go farther without attenuation.

Detailed explanation-5: -Fiber optics is used for long-distance and high-performance data networking. It is also commonly used in telecommunication services, such as internet, television and telephones.
