标准摘要
[中文适用范围]： IEC 61753-086-02:2025 包含光纤尾纤 1 490/1 550 nm 下行和 1 310 nm 上行宽波分复用 (WWDM) 无源光网络 (PON) 设备将满足的最低初始性能、测试和测量要求及严酷程度，以归类为满足 IEC 61753-1:2018 附件 A 中定义的 C 类（室内受控环境）的要求。WWDM 在 IEC 62074-1 中定义。附件 B 提供了这些 PON WWDM 设备的一般信息。此第一版取消并取代了 2009 年发布的 IEC 61753-086-2 第一版。此版本为技术修订。与上一版相比，此版本包括以下重大技术变化：a) 更改测试条件以与 IEC 61753-1: 2018 协调。 [外文原描述]： IEC 61753-086-02:2025 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed 1 490/1 550 nm downstream and 1 310 nm upstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device will satisfy in order to be categorized as meeting the requirements of category C (indoor controlled environment), as defined in IEC 61753-1:2018, Annex A. WWDM is defined in IEC 62074-1. Annex B gives general information for these PON WWDM devices. This first edition cancels and replaces the first edition of IEC 61753-086-2 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Change of test conditions harmonizing with IEC 61753-1: 2018.
