Optical fibres - Measurement methods and test procedures. Numerical aperture measurement algolia-search-ignore Decision subsystem1 Scope This part of IEC 60793 establishes uniform requirements for measuring the numerical aperture of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. The numerical aperture (NA) of categories A1, A2, A3 and A4 multimode fibre is an important parameter that describes a fibre's light gathering ability. It is used to predict launching efficiency, joint loss at splices, and micro macrobending performance.
