标准摘要
[中文适用范围]： IEC 60793 的这一部分规定了测量光纤涂层几何形状的统一要求。涂层几何形状测量是后续程序（例如布线、连接、拼接、处理和进行其他测量）需要了解的基本值。 [外文原描述]： Gives four methods for measuring the coating geometry of optical fibres. The following parameters are measured: coating diameter, coating non-circularity, coating-cladding concentricity error. The methods are conducted off-line during inspection. They are not suitable for on-line, in-process measurements.
