IEC 61753-1:20 18+A1:2020为所有无源光纤产品的性能标准起草提供了指导。本文件定义了构成性能类别或一般操作服务环境的测试和严重性，并确定了被认为是特定于产品的测试。试验和严重程度详情见附录A。这第二版取消并取代了2007年出版的第一版。它构成技术修订。与上一版相比，此版本包括以下重大技术变更: a)新产品更新的定义:墙壁插座、墙壁或杆安装盒、接头、ODF模块、街道机柜、硬化连接器和现场安装连接器； b)类别U和O被类别OP和OP+取代。OP+类别中没有强制序列。类别OP+包含类别OP的测试，仅增加了4个其他测试； c)增加I类（工业）； d)在无源光学部件与有源电子器件一起放置在外壳中的情况下添加的温度范围(用HD后缀添加到类别C、OP、OP+和I)(HD代表“散热”)； e)A类高度由3米改为地面（0米）； f）G类环境下层高度由地面（0 m）变为地面以下-1 m。上层保持在地面以上3米； g)增加新产品的性能测试、测试严重性和性能标准:墙壁插座、墙壁或杆安装盒、机械接头、熔接线保护器、ODF模块、街道机柜、现场安装连接器和硬化光学连接器；h)对于C类、OP类、OP+类和I类连接器的“配合耐久性”测试的测试严重性对于具有圆柱形套圈的连接器降低至200次循环，对于具有矩形套圈的连接器降低至50次循环； i)I类连接器和无源光学元件的“温度变化”测试的测试严重性从20个循环降低到12个循环（与其他类别的连接器和元件协调）； j)C类、OP类和OP+类连接器的“应变消除弯曲”测试的测试严重度降低至50次循环； k)所有外壳的“光纤机械接头、光纤管理系统和封闭件的组装和拆卸”测试的测试严重性降低至5个周期； l)C、A、G和S类中所有保护外壳的“温度变化”测试的测试严重性从20个循环减少到12个循环（与连接器和组件协调）；m)对G类和S类封闭件的“耐溶剂和污染流体”测试的严重性进行了改变——去除煤油，将柴油暴露减少到浸泡1小时，并在室温下干燥24小时； n)G类和A类密封件的密封性能标准降低至20kPa超压。 o)连接器衰减标准的变化已从峰值到峰值变为与测试开始时传输功率原始值的+/-偏差（与组件、接头和保护外壳衰减标准的变化相协调）。 关键词:所有无源光纤产品的性能标准 2019年5月勘误表的内容已纳入本副本。该合并版本由第二版（2018年）及其修正案1（2020年）组成。因此，除本出版物外，无需下令修订。

IEC 61753-1:2018+A1:2020 provides guidance for the drafting of performance standards for all passive fibre optic products. This document defines the tests and severities which form the performance categories or general operating service environments and identifies those tests which are considered to be product specific. Test and severity details are given in Annex A. This second edition cancels and replaces the first edition published in 2007. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) definitions updated with new products: wall outlets, wall or pole mounted boxes, splices, ODF modules, street cabinets, hardened connectors and field mountable connectors;
b) categories U and O are replaced by categories OP and OP+. No mandatory sequence in category OP+. Category OP+ contains the tests from category OP with the addition of only 4 other tests;
c) addition of Category I (Industrial);
d) temperature ranges added (with the HD suffix to the categories C, OP, OP+ and I) in case passive optical components are placed in a housing together with active electronics (HD stands for “heat dissipation”);
e) the height of category A changed from 3 m to ground level (0 m);
f) the lower level height of category G environment changed from ground level (0 m) to –1 m below ground level. Upper level remains at 3 m above ground level;
g) addition of performance tests, test severities and performance criteria for new products: Wall outlet, wall or pole mounted boxes, mechanical splices, fusion splice protectors, ODF modules, street cabinets, field mountable connectors and hardened optical connectors;
h) test severity of "Mating durability" test for connectors in categories C, OP,OP+ and I is reduced to 200 cycles for connectors with cylindrical ferrules and 50 cycles for connectors with rectangular ferrules;
i) test severity of "Change of temperature" test for connectors and passive optical components in category I is reduced from 20 cycles to 12 cycles (harmonized with connectors and components from other categories);
j) test severity of "Flexing of strain relief" test for connectors in categories C, OP and OP+ is reduced to 50 cycles;
k) test severities of "Assembly and disassembly of fibre optic mechanical splices, fibre management systems and closures" test for all enclosures is reduced to 5 cycles;
l) test severities of "Change of temperature" test for all protective housings in categories C, A, G and S is reduced from 20 cycles to 12 cycles (harmonized with connectors and components);
m) test severities of "Resistance to solvents and contaminating fluids" test for closures in categories G and S changed – kerosene is removed, diesel oil exposure reduced to 1 h immersion and 24 h drying at room temperature;
n) sealing performance criteria of sealed closures for categories G and A are reduced to 20 kPa overpressure.
o) the change in attenuation criterion for connectors has changed from peak-to-peak into a +/- deviation from the original value of the transmitted power at the start of the test (harmonized with the change in attenuation criterion for components, splices and protective housings).
