标准摘要
[中文适用范围]： IEC 60793的这一部分制定了测量光纤数值孔径的统一要求，从而有助于商业用途的光纤和电缆的检查。 A1类渐变折射率多模光纤的数值孔径（NA）是描述光纤聚光能力的重要参数。它用于预测发射效率、接头处的接头损耗以及微/宏观弯曲性能。 [外文原描述]： Establishes requirements for measuring the numerical aperture of category A1 graded-index multimode fibre, and its light-gathering ability. This is used to predict lauching efficiency, joint loss at splices, and micro/macrobending perfprmance.
