标准范围

IEC 60793-1-44:2023建立了测量单模光纤截止波长的统一要求，从而有助于商业用途光纤和电缆的检查。本文件给出了测量无缆或有缆单模电信光纤截止波长的方法。这些程序适用于所有B类和C类纤维类型。有三种用于测量截止波长的部署方法:-方法A:使用22米长的无缆光纤样品lcc切断电缆；-方法B:使用电缆光纤22m长样品lcc切断电缆；-方法C:使用2 m长的无缆光纤样品进行光纤切断，lc。所有方法都需要参考测量。有两种参考扫描技术，其中一种或两种都可以用于所有方法:-弯曲-参考技术；-使用A1类(OM1-OM5)多模光纤的多模参考技术。这第三版取消并取代了2011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)使用纤维环的直径来描述展开；b)增加了与截止曲线伪影相关的附录D；c)重新组织信息并添加更多数字以澄清概念。

IEC 60793-1-44:2023 establishes uniform requirements for measuring the cut-off wavelength of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. This document gives methods for measuring the cut-off wavelength for uncabled or cabled single mode telecom fibre. These procedures apply to all category B and C fibre types. There are three methods of deployment for measuring the cut-off wavelength:
- method A: cable cut-off using uncabled fibre 22 m long sample, lcc;
- method B: cable cut-off using cabled fibre 22 m long sample, lcc;
- method C: fibre cut-off using uncabled fibre 2 m long sample, lc.
All methods require a reference measurement. There are two reference-scan techniques, either or both of which can be used with all methods:
- bend-reference technique;
- multimode-reference technique using category A1(OM1-OM5) multimode fibre.
This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) used the diameter of the fibre loops to describe deployment;
b) added Annex D related to cut-off curve artifacts;
c) reorganized information and added more figures to clarify concepts.
