标准摘要
[中文适用范围]： 本部分IEC 61753包含了光纤尾纤式宽波长分复用（WWDM）器件用于监测采用光时域反射仪（OTDR）的无源光网络（PON）所需满足的最低初始测试和测量要求及严酷度等级，以便归类为符合IEC 61753-1:2018附录A中定义的C类（室内受控环境）要求。WWDM的定义见IEC 62074-1。 [外文原描述]： IEC 61753-089-02:2022 contains the minimum initial test and measurement requirements and severities which a fibre-optic pigtailed wide wavelength division multiplexing (WWDM) device for monitoring passive optical networks (PON) using an optical time-domain reflectometer (OTDR) satisfies in order to be categorised as meeting the requirements of category C (indoor controlled environment), as defined in Annex A of IEC 61753-1:2018. WWDM is defined in IEC 62074-1. This first edition cancels and replaces IEC 61753-089-2 published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to IEC 61753‑089‑2:2013: change of test conditions harmonizing with IEC 61753-1:2018.
