[中文适用范围]： 本部分为IEC 61282的技术报告，详细分析和计算了使用光源和功率计测量多模和单模光纤布线衰减时的不确定性。还包括使用OTDR测量单模光纤布线衰减时的不确定性的简化分析和计算。 [外文原描述]： IEC TR 61282-14:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
