光缆第6-20部分:室内外电缆阻燃室外电缆系列规范

[中文适用范围]： 本部分 IEC 60794 是一个系列规范，涵盖阻燃光缆，适用于室外和室内环境。这些光缆通常具有与室外光缆设计相似的热和机械特性，使其适用于外部设备，同时满足室内场所的防火性能要求。典型的应用包括将室外光缆的“短长度”延伸至建筑物内。 [外文原描述]： IEC 60794-6-20:2020 is a family specification covering optical fibre outdoor cables which are flame retardant and thus also applicable to indoor environments. These cables generally possess the characteristics associated with outdoor cable designs having similar thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously exhibiting the fire performance required in indoor premises. A typical application is for example the extension of a "shorter length" of an outdoor cable into the building.
