This calculator computes the V parameter/number (also known as normalized frequency) of a step-index optical fiber. The V parameter is defined as V = dfrac {2pi} {lambda} a mathrm {NA} V = λ2πaNA where lambda λ is the wavelength of the signal, a a is the core radius of the fiber and mathrm {NA} NA is the numerical aperture of its core.

As a general rule, screen capacity at any given level of efficiency, other things being equal, will be dependent not only on the size of the aperture, but also on the slope of the size distribution curve through the cutpoint. This latter characteristic is taken into account in the test-data-based Fractional Efficiency calculations8.
