标准范围

IEC 61753-121-2:20 17规定了根据IEC 61753-1在受控（C类）环境中使用的电线（包括参考电线）的测试要求，其中连接器已经符合IEC 61753-1的C类要求。所选测试是IEC 61753-1连接器测试的子集，适用于具有与软线和连接器/电缆接口相关的附加要求的再鉴定。电缆由单工或双工光缆组成，端接在光缆的每一端，带有带圆柱形套圈的单模光纤连接器插头。操作波长范围在1260nm和1625nm之间。较短长度的电缆用作测试样品，因为较长长度的电缆会影响电缆的衰减和温度循环性能。长度大于5 m的绳索的任何鉴定都要考虑这些因素，这一点很重要。IEC 61754所有部分涵盖了连接器组机械接口的相关要求。IEC 61755（所有部分）涵盖了连接器组光学接口的相关要求。IEC 61753（所有部分）涵盖了连接器组性能的相关要求。IEC 60793-2-50涵盖了光纤的相关要求。IEC 60794-2-50涵盖了软线用电缆的相关要求。第二版取消并取代了2010年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-合并参考线的光学性能要求；-由于更新了相关标准文件，因此删除附件D和E；-根据最新的ISO/IEC指令修改整个文档结构。

IEC 61753-121-2:2017 specifies the test requirements for cords including reference cords used in a controlled (Category C) environment according to IEC 61753-1, where the connectors already comply with the Category C requirements of IEC 61753-1. The tests selected are a subset of the connector tests from IEC 61753-1 appropriate for requalification with additional requirements relevant to cords and the connector/cable interface. The cords consist of simplex or duplex fibre optic cable terminated at each end of the cable with single-mode fibre optic connector plugs with cylindrical ferrules. The operational wavelength range is between 1 260 nm and 1 625 nm. Short length cords are used as test samples as the attenuation of the cord and the temperature cycling performance will be affected by longer lengths of cable. It is important that any qualification of a cord whose length is greater than 5 m takes these factors into account. The relevant requirements for the mechanical interface of connector sets are covered by the IEC 61754 all parts. The relevant requirements for the optical interface of connector sets are covered by IEC 61755 (all parts). The relevant requirements for performance of connector sets are covered by IEC 61753 (all parts). The relevant requirements for fibres are covered by IEC 60793-2-50. The relevant requirements for cables for cords are covered by IEC 60794-2-50. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- merge an optical performance requirement of a reference cord;
- delete Annexes D and E due to updated relevant standard document;
- modify the whole document structure according to the latest ISO/IEC Directives.
