- A graded-index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the optical axis of the fiber.
- Due to parts of the core closer to the fiber axis have a higher refractive index than the parts near the cladding, light rays after total reflection follow a parabolic path.
- Due to the parabolic path, refocussing of the signal within the core is increased, which eventually increases the data rate.
