    WEBNumerical aperture Numerical aperture (NA), shown in Figure 4, is the measure of maximum angle at which light rays will enter and be conducted down the fiber. This is represented by the following equation: Dispersion As the optical pulses travel the length of the fiber, they are broadened or lengthened in time. This is called dispersion.

    WEBDefinition: Numerical Aperture is the measure of the ability of an optical fiber to collect or confine the incident light ray inside it. It is among the most basic property of optical fiber. Numerical aperture is abbreviated as NA and shows the efficiency with which light is collected inside the fiber in order to get propagated.
