IEC 61755-6-2:20 18定义了参考连接器光学接口的尺寸限制，以满足非成角度抛光多模参考连接器的光纤到光纤互连的特定要求，这些参考连接器具有圆柱形套圈，旨在用于现场或工厂的衰减测量。本文件中定义了参考连接器的一个等级。参考连接器端接至选定的IEC 60793-2-10:20 15 A1A光纤。已经开发了指定参考连接器的几何尺寸和公差，主要是为了限制多组两个参考连接器之间的测量衰减的变化，并且因此限制当与现场或工厂中的连接器配合时随机选择的参考连接器之间的测量衰减的变化。 关键词:光接口、光纤到光纤互连

IEC 61755-6-2: 2018 defines the dimensional limits of an optical interface for reference connectors necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled polished multimode reference connectors with cylindrical ferrules intended to be used for attenuation measurements in the field or factory. One grade of reference connector is defined in this document. The reference connector is terminated to selected IEC 60793-2-10:2015 A1a fibre. The geometrical dimensions and tolerances of the specified reference connector 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.
