标准范围

IEC 60793-1-45:2024作为IEC 60793-1-45:2024 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60793-1-45:2024制定了测量单模光纤模场直径(MFD)的统一要求，从而有助于商业用途光纤和电缆的检查。这第三版取消并取代了2017年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a）修改直接远场扫描的光纤端和检测器之间的最小距离（附录A）。b)所有纤维类型的最小动态范围要求的概括（附录A）。

IEC 60793-1-45:2024 is available as IEC 60793-1-45:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60793-1-45:2024 establishes uniform requirements for measuring the mode field diameter (MFD) of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) modification of the minimum distance between the fibre end and the detector for the direct far field scan (Annex A).
b) generalization of the requirement for the minimum dynamic range for all fibre types (Annex A).
