GB/T 15972.43-2008 Specifications for optical fibre test methods.Part 43:Measurement methods and test procedures for transmission and optical characteristics.Numerrical aperture (English Version)
This part of GB/T 15972 specifies the test methods for the numerical aperture of optical fibers, and establishes uniform requirements for test devices, injection conditions, procedures, calculation methods and results. This part applies to the measurement of the numerical aperture of class A1 and class A2 multimode optical fibers and the commercial inspection of finished optical fiber cables. The measurement of the numerical aperture of A3 and A4 multimode fibers can also be used as a reference.
