光纤互连器件和无源部件 性能标准 第022-02部分：类别C-受控环境用作为尾纤和跳线端接的多模光纤连接器

[中文适用范围]： IEC 61753-022-02:2026 规定了多模光纤连接器（以尾纤或跳线形式端接）在满足 IEC 61753-1 所定义的 C 类（受控环境）标准分类时，所应达到的最低初始测试与测量要求及严酷度。本第一版取代了 2012 年发布的 IEC 61753-022-2 第二版，属于技术性修订。相较于前一版本，本版本包含以下重要技术变更：a) 新增矩形插芯连接器的相关规定；b) 增补术语与定义；c) 依据 IEC 60793-2-10 更新光纤命名规范；d) 依据 IEC 61753-1 更新测试严酷度；e) 新增扭转测试；f) 将增强型电缆的纤缆保持测试时长从 120 秒缩短至最低 60 秒；g) 删除静侧向负载测试；h) 将应变消除弯曲测试改为采用衰减变化而非瞬态损耗；i) 将圆形插芯连接器的插拔耐久性循环次数由 500 次减至 200 次；j) 新增矩形插芯连接器的插拔耐久性要求，设定为 50 次循环；k) 新增附录 B，作为温度变化、纤缆保持及应变消除弯曲测试中增强型电缆外护套位移的目视检查附加要求。 [外文原描述]： IEC 61753-022-02: 2026 defines the minimum initial test and measurement requirements and severities which multimode fibre optic connectors terminated as a pigtail or patchcord satisfy in order to be categorized as meeting the IEC standard category C (controlled environment), as defined in IEC 61753‑1. This first edition cancels and replaces the second edition of IEC 61753-022-2 published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of provisions for rectangular ferrule connectors; b) additions of terms and definitions; c) update of the fibre naming conventions in accordance with IEC 60793-2-10; d) update of test severities in accordance with IEC 61753‑1; e) addition of the torsion test; f) reduction of the duration of the fibre/cable retention test on reinforced cables from 120 s to 60 s minimum; g) deletion of the static side load test; h) update of the flexing of the strain relief test to use the change in attenuation instead of the transient loss; i) reduction of the number of mating durability cycles for cylindrical ferrule connectors from 500 cycles to 200 cycles; j) addition of the mating durability for rectangular ferrule connectors with 50 cycles; k) addition of Annex B for visual examination of the outer cable sheath movement of reinforced cables as an additional requirement for change of temperature, cable retention and flexing of the strain relief tests.
