标准摘要
[中文适用范围]： 本文档包含用于分类为符合 C 类 - 受控环境要求的插孔式单模光纤固定光衰减器所需的最小初始测试和测量要求及严酷程度，该要求定义见 IEC 61753-1:2018 附录 A。 [外文原描述]： IEC 61753-051-02:2022 contains the minimum initial test and measurement requirements and severities which plug-receptacle style single-mode fibre fixed optical attenuators need to satisfy in order to be categorized as meeting the requirements of category C – Controlled environments, as defined in IEC 61753-1:2018, Annex A. This first edition cancels and replaces IEC 61753-051-3 published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61753‑051‑3:2013: change the category from U to C and the test items and their conditions according to IEC 61753-1; change the requirements reflecting the survey results.
