Detailed explanation-1: -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-2: -Fiber-optic cables 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-3: -An optical fiber consists of three basic concentric elements: the core, the cladding, and the outer coating (Figure 1). The core is usually made of glass or plastic, although other materials are sometimes used, depending on the transmission spectrum desired. The core is the light-transmitting portion of the fiber.
Detailed explanation-4: -Optical fibers are arranged in bundles called optical cables and are used to transmit light signals over long distances.
Detailed explanation-5: -Optical fibers use total internal reflection to transmit light. It has a solid core of dense glass surrounded by a less dense cladding. The light ray passing through the inner core is reflected back instead of being refracted to the rarer cladding.
