In optics and lens design, the Abbe number, also known as the V-number or constringence of a transparent material, is an approximate measure of the material's dispersion (change of refractive index versus wavelength), with high values of V indicating low dispersion. It is named after Ernst Abbe (1840–1905), the German physicist who defined it. The term V-number should not be confus… Webby the V number of the fiber which is defined as such that V ≤2.405. •Here, n 1 = refractive index of the core; a = radius of the core; λ= wavelength of the light propagating through the fiber; Δ= relative refractive indices difference.

For example, the number of guided modes in a step index multimode fiber is given by: V2/2, and a step index fiber becomes single-mode for a given wavelength when V<2.405. Mathematically: V = 2π·NA·a/λ = 2π·a/λ·sqrt (n core 2 – n clad 2) a is the fiber core radius n WebV >2:405. For a ﬂber withV= 4, for instance, four modes are possible. The power in each mode depends on how the light is coupled into the ﬂber. After light has propagated a certain distance in the ﬂber, a stable mode distribution develops.
