标准摘要
[中文适用范围]： 本部分IEC 63267定义了光学接口的尺寸限制，用于参考连接，以满足现场或工厂中用于衰减测量的非角度和角度抛光多模参考连接器的光纤互连的特定要求。本文档定义了几种参考连接等级。多模参考连接仅终止于限制性的IEC 60793-2-10 A1-OM2b至A1-OM5b光纤在850 nm波段。指定的参考连接的几何尺寸和公差主要是为了限制多组两个参考连接器之间测量的衰减变化，从而限制在现场或工厂中随机选择的参考连接器与连接器配合时测量的衰减变化。 [外文原描述]： IEC 63267-2-2:2024 defines the dimensional limits of an optical interface for reference connections necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled and angled polished multimode reference connectors intended to be used for attenuation measurements in the field or factory. Several grades of reference connections are defined in this document. The multimode reference connections are terminated to restricted IEC 60793-2-10 A1-OM2b to A1-OM5b fibre at the 850 nm band only. The geometrical dimensions and tolerances of the specified reference connections have been developed primarily to limit the variation in measured attenuation between multiple sets of two reference connectors, and therefore to limit the variation in measured attenuation between randomly chosen reference connectors when mated with connectors in the field or factory.
