纤维光学互连器件和无源元件 纤维光学连接器光学接口 第1部分:增强型宏观弯曲损耗多模50μm芯径光纤 总则和指南

[中文适用范围]： 本部分 IEC 63267 涵盖了增强型宏弯损耗 50 µm 芯径多模光纤连接接口。它包括参考文件、文档结构细节、定义和标准化的光学连接等级。这些等级基于根据规定特性（包括芯径和数值孔径失配）在两个光连接器群体之间的随机配对连接。 本文档描述了创建光学接口的规则。 它还定义了标准化的测试方法（在适用的情况下）。 [外文原描述]： IEC 63267-1: 2023 covers enhanced macrobend loss 50 µm core diameter multimode fibre optic connection interfaces. It includes references, document structure details, definitions, and standardised optical connection grades. The grades are based on random mated connections between two optical connector populations according to prescribed characteristics including the core diameter and numerical aperture mismatches. This document describes the rules under which an optical interface is created. It also defines standardised test methods where appropriate.
