标准范围

IEC 61753-021-02:20 23定义了端接为尾纤或跳线的单模光纤连接器满足的最低初始测试和测量要求以及严重性，以便被归类为符合IEC标准C类（受控环境），如IEC 61753-1所定义。如果对端接为OP+HD、OP+、OP、OPHD或CHD类别的尾纤或跳线的连接器进行了测试，并且产品通过，则产品将自动合格或分类为符合IEC C类标准。第一版取消并取代了2007年发布的IEC 61753-021-2的第二版。本版构成技术修订版。本版本包括以下与IEC 61753-021-2:20 07相关的重大技术变更:a)改变范围，取消对衰减和回波损耗等级的限制；b)包括矩形套圈连接器的规定；c)改变了各种测试中使用的不同类型测试样品（尾纤测试样品和跳线测试样品）的术语和定义，以避免混淆；d)根据IEC 60793-2-50更新了纤维命名约定，并增加了B-657纤维的规定；e)增加了IEC 61753-1中定义的所有衰减和回波损耗等级；f)根据IEC 61753-1更新的测试严重性；g)应变消除循环的弯曲从100个循环减少到50个循环；h)增加了扭转试验；i)将增强电缆上的光纤/电缆保持测试的持续时间从120秒减少到最小60秒；j)取消了静态侧载试验；k)将配合耐久性循环次数从500个循环减少到200个循环，并增加了矩形插芯连接器的规定；l)增加了附录B，用于目视检查加固电缆的外部电缆护套移动，作为温度变化、电缆保持力和应变消除试验弯曲的附加要求。

IEC 61753-021-02:2023 defines the minimum initial test and measurement requirements and severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorized as meeting the IEC standard category C (controlled environment), as defined in IEC 61753-1. If tests were performed on the connectors terminated as pigtails or patchcords for categories OP+HD, OP+, OP, OPHD, or CHD and the product passed, the product will be automatically qualified or categorized as meeting the IEC standard for category C. This first edition cancels and replaces the second edition of IEC 61753-021-2 published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61753-021-2:2007:
a) changed scope to remove restrictions on attenuation and return loss grades;
b) included provisions for rectangular ferrule connectors;
c) changed the terms and definitions of the different types of test samples (pigtail test samples and patchcord test samples) used in the various tests to avoid confusion;
d) updated fibre naming conventions according to IEC 60793-2-50 and added provisions for B-657 fibres;
e) added all the attenuation and return loss grades defined in IEC 61753-1;
f) test severities updated according to IEC 61753-1;
g) reduced flexing of strain relief cycles from 100 cycles to 50 cycles;
h) added the torsion test;
i) reduced the duration of the fibre/cable retention test on reinforced cables from 120 s to 60 s minimum;
j) removed the static side load test;
k) reduced the number of mating durability cycles from 500 cycles to 200 cycles and added provisions for rectangular ferrule connectors;
l) added 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.
