标准摘要
[中文适用范围]： IEC 60793 的这一部分规定了测量无涂层光纤几何特性的统一要求。无涂层光纤的几何特性是基本值，对于执行后续程序（例如处理、熔接、连接器、布线和测量）是必要的。 [外文原描述]： Gives four methods for measuring the geometry of uncoated optical fibres. Parameters include: cladding diameter, cladding non-circularity, core diameter, core non-circularity, core-cladding concentricity error, and theoretical numerical numerical aperture.
