"網頁The V number can be interpreted as a kind of normalized optical frequency. (It is proportional to the optical frequency, but rescaled depending on waveguide properties.)It is relevant for various essential properties of a fiber: For V values below ≈ 2.405, a fiber supports only one mode per polarization direction (→ single-mode fibers). ...

For a step-index fiber (both single mode and multimode optical fibers), the refractive index of the core is uniform throughout the cladding region and undergoes an abrupt change at the core-cladding boundary. Step-index fibers obtain their name from this abrupt change called the step change in refractive index. how to start a blog for free ukThe advantage of the multi-mode graded index compared to the multi-mode step index is the considerable decrease in modal dispersion. Modal dispersion can be further decreased by selecting a smaller core size (less than 5–10 μm) and forming a single-mode step index fiber . 查看更多內容 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.
