纤维光学互连器件和无源元件.性能标准.第1部分:总则和指南

[中文适用范围]： 本部分IEC 61753为所有无源光纤产品（包括连接器、无源光学组件、光纤管理系统和封闭件）的性能标准起草提供指导。IEC 61753系列分为多个部分发布。本第1部分涵盖性能标准的通用信息。本文档定义了构成性能类别或通用操作服务环境的测试和严重程度，并确定了那些被认为是产品特定的测试。测试和严重程度细节在附录A中给出。第1部分还包括创建性能标准的参考、定义和规则，以及信息性附录，如附录B中给出的测试序列描述，以及其他相关信息。后续构成IEC 61753的部分被称为性能标准，并根据附录C中定义的分类进行编号。这些标准包含特定产品必须满足的最低测试和测量严重程度，以便被分类为满足在特定服务环境中使用的要求。产品性能标准将包含那些对特定服务环境或性能类别对所有无源光纤产品通用的测试和测量，以及那些被认为特定于该特定产品在该环境中的测试和测量。 [外文原描述]： IEC 61753-1:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61753-1:2018 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).
