AbolishedSpecifications for optical fibre test methods - Part 43: Measurement methods and test procedures for transmission and optical characteristics - Numerrical aperture
光纤试验方法规范 第43部分：传输特性和光学特性的测量方法和试验程序 数值孔径
Application Summary AI generated
This standard specifies the test method for measuring the numerical aperture (NA) of optical fibres, which defines the light-gathering ability and acceptance angle of the fibre core. It is applied in the telecommunications industry for quality control, product certification, and performance verification of single-mode and multimode optical fibres used in network cabling and optical communication systems. The measurement procedure ensures consistent optical coupling efficiency between fibres, connectors, and light sources during manufacturing and field testing.
