Graded Index Fiber : Working, Differences and Its Applications

WebMay 7, 2024 · There are two major types of refractive-index profiles – step index (SI) and graded index (GI) – and they are schematically shown in Figure 3. The core of a SI fiber has a uniformly raised refractive index profile, and that of a GI fiber has a continuously raised refractive index profile. WebOther articles where graded-index fiber is discussed: telecommunications media: Optical fibres: Graded-index (GI) fibre reduces multimode dispersion by grading the refractive index of the core so that it smoothly tapers between the core centre and the cladding.
