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 optics, or optical fiber, refers to the technology that transmits information as light pulses along a glass or plastic fiber. A fiber optic cable can contain a varying number of these glass fibers–from a few up to a couple hundred. Another glass layer, called cladding, surrounds the glass fiber core.

Detailed explanation-3: -Just as copper cables use pulses of electricity to carry signals across a copy wire, Fiber Optic cable uses pulses of light. For digital communication we transmit in ones and zeros. For copper, the difference between a one and a zero is a change or variation in the electric pulse within a certain acceptable range.
