IEC 60794的这一部分是涵盖光纤电缆特性的系列规范 适用于室外和室内环境，称为“通用室内电缆”。 这些电缆通常具有与室外电缆设计相关的特性 （根据IEC 60794-3，但通常不太严格，且通常为“非铠装”） 具有热稳定性和机械稳定性，适合在室外使用 植物，同时具有足够的灵活性、紧凑性和轻质性，并表现出 室内场所所需的防火性能。典型的应用程序是集中式的 中心办公室和场所或局域网内的布线，其中电缆设计相同 用于电缆连接的整个长度，包括室内和室外 部分。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 60794 is a family specification covering features of optical fibre cables applicable to outdoor as well as indoor environments, called "universal indoor-outdoor cables". These cables generally possess the characteristics associated with outdoor cable designs (according to IEC 60794-3, however typically less stringent, and typically "non armoured") having the thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously being flexible enough, compact and lightweight and exhibiting the fire performance required in indoor premises. A typical application is for example the centralized cabling in central office and the premises or local area network where the same cable design is used for the entire length of the cabling link including both the indoor as well as the outdoor portions.All current amendments available at time of purchase are included with the purchase of this document.
