IEC-60793-1-43

Measurement methods and test procedures: Numerical Aperture. This part of IEC 60793 establishes uniform requirements for measuring the Numerical Aperture of optical fiber, thereby assisting in the inspection of fibers and cables for commercial purposes. The numerical aperture (NA) of graded index multi mode fiber is an important parameter that describes a fibers light-gathering ability. NA is used to predict launching efficiency, joint loss at splices, and micro/macrobending performance.
