A graded-index or gradient-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. Because parts of the core closer to the fiber axis have a higher refractive index than the parts near the cladding, light rays follow sinusoidal paths down the fiber. The most common refractive index profile for a graded-index fiber is very nearly parabolic. The parabolic profile results in conti… Web10 rows · Graded-index multimode optical fibers, optimized for signal transmission at 850 and 1300 nm, are available with 50/125, 62.5/125 and 100/140 µm core/cladding diameters.
