ActiveSpecifications for optical fibre test methods—Part 43: Measurement methods and test procedures for transmission characteristics—Numerical aperture
光纤试验方法规范 第43部分：传输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 methods for measuring the numerical aperture (NA) of optical fibres, which is a key parameter defining the light-gathering ability and modal properties of the fibre. It is applied in the telecommunications industry for quality assurance and performance verification of multimode optical fibres used in data transmission networks, local area networks, and fibre optic sensing systems. The procedures ensure consistent measurement across manufacturing, installation, and laboratory testing environments.
