标准摘要
[中文适用范围]： IEC 61753 的这一部分包含光纤尾纤 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) 设备必须满足的最低初始性能@测试和测量要求以及严重性以便被归类为满足 IEC 61753-1 附录 A 中定义的 C 类（受控环境）@ 的要求。本标准的附件 B 提供了有关 1 490 / 1 550 nm 下行和 1 310 nm 上行 WWDM 功能的信息。 [外文原描述]： IEC 61753-086-2:2009 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 must satisfy in order to be categorized as meeting the requirements of category C (controlled environments), as defined in Annex A of IEC 61753-1. Annex B of this standard provides information concerning the function of the 1 490 / 1 550 nm downstream and 1 310 nm upstream WWDM. Keywords: category C (controlled environments), WWDM, PON
