标准摘要
[中文适用范围]： IEC 60793 的这一部分制定了测量光纤（通常在电缆内）长度和伸长率的统一要求。光纤的长度是最基本的值之一，在评估损耗和带宽等传输特性时应了解该长度。 [外文原描述]： Gives methods for measuring the length and elongation of optical fibres (typically within a cable). Length is fundemental for evaluation of transmission characteristics such as losses and bandwidths. Five methods are described: delay measurement, backscattering, fibre elongation, mechanical length, and phase shift.
