IEC TR 61282-14:20 24作为IEC TR 61282-14:20 24 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 TR 61282-14:20 24是一份技术报告，对使用光源和功率计测量多模和单模光缆衰减相关的不确定性进行了详细分析和计算。它还包括与使用OTDR测量单模光纤电缆衰减相关的不确定性的简化分析和计算。本文档包含一个Excel电子表格形式的附件。本文件旨在作为补充，不构成文档的组成部分。这第三版取消并取代了2019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)根据61280-4-3中提供的分析，增加光时域反射计（OTDR）测量方法的不确定度计算； b)增加无源光网络(PON)的不确定性计算； c)参考等级连接器列表的更新； d)在表D.1中添加概率分布。

IEC TR 61282-14:2024 is available as IEC TR 61282-14:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC TR 61282-14:2024, which is a Technical Report, establishes a detailed analysis and calculations of the uncertainties related to the measurement of the attenuation of both multimode and single-mode optical fibre cabling, using optical light sources and power meters. It also includes simplified analysis and calculation of the uncertainties related to the measurement of the attenuation of single-mode optical fibre cabling using OTDRs. This document contains an attached file in the form of an Excel spreadsheet. This file is intended to be used as a complement and does not form an integral part of the document. This third edition cancels and replaces the second edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of uncertainties calculation for optical time domain reflectometer (OTDR) measurement methods based on the analysis provided in 61280-4-3;
b) addition of uncertainties calculation for passive optical networks (PON);
c) update of the list of reference grade connectors;
d) addition of probability distribution in Table D.1.
