标准摘要
[中文适用范围]： IEC TR 62316:2026 RLV 包含官方的IEC国际标准及其红线版本。红线版本仅提供英文版，便于用户快速比较官方IEC标准与其前一版之间的所有变更。IEC TR 62316:2026 是一份技术报告，提供了对传统光时域反射仪（OTDR）在单模光纤中获得的背向散射曲线的解释指南。本文件不涵盖偏振OTDR。此外，还讨论了单向曲线情况下背向散射功率的影响。有关测试测量程序的完整描述，请参见IEC 60793-1-40:2024 附录C。本第四版取消并替换了2017年发布的第三版。本版为技术修订版。与前一版相比，本版包括以下重大技术变更：a）更新光纤类型；b）增加了关于衰减均匀性的信息。 [外文原描述]： IEC TR 62316:2026 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 62316:2026 which is a Technical report, provides guidance on the interpretation of backscattering traces, as obtained by traditional optical time domain reflectometers (OTDRs) for single-mode fibres. This document does not cover Polarization OTDRs. Also, backscattered power effects are discussed in case of unidirectional trace. Full description of the test measurement procedure can be found in Annex C of IEC 60793‑1‑40:2024. This fourth edition cancels and replaces the third 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) update of the fibre types; b) addition of information as regards attenuation uniformity.
