WebOptical fibers can have different transverse refractive index profiles. Apart from such fibers where light is guided at the air–glass interface, the simplest index profile is a rectangular one, where the refractive index is constant within the fiber core, and is higher than in the cladding . Fibers of that kind are called step-index fibers . WebOct 30, 2024 · The fiber optic core's refractive index will change the speed of the transmission of the wave packet (the rate of information delivery) with the relation $\frac{1}{n}$. The cladding of the fiber will not in any way effect the speed of light transmission in the fiber. It will, however, change the intensity coming through the far …
