IEC 60794-3:20 22作为IEC 60794-3:20 22 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60794-3:20 22规定了要求用于通信网络外部使用的光纤电缆和电缆元件。可以考虑需要类似类型电缆的其他类型的应用。本文件包括管道中使用的电缆、直埋应用、架空电缆以及湖泊和河流穿越电缆的要求。还包括专门用于下水道、水管和煤气管道的电缆。对于架空应用，本文件不涵盖安装在架空电力线附近的电缆的所有功能方面。对于此类应用，可能需要额外的要求和测试方法。此外，本文件不包括连接到架空电力线的相导体或接地导体的光学接地线和电缆。对于穿越湖泊和河流的电缆，本文件不包括电缆修复方法，也不包括修复能力，也不包括用于水下线路放大器的电缆。这第五版取消并取代了2014年出版的第四版。本版构成技术修订版。与上一版本相比，此版本包括以下重大技术变化:色带规范已被删除，因为它包含在IEC 60794-1-31中。

IEC 60794-3:2022 is available as IEC 60794-3:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60794-3: 2022 specifies the requirements for optical fibre cables and cable elements which are intended to be used externally in communications networks. Other types of applications requiring similar types of cables can be considered. Requirements for cables to be used in ducts, for directly buried applications, aerial cables and cables for lake and river crossings are included in this document. Also included are cables for specialized use in sewers and in water and gas pipes. For aerial application, this document does not cover all functional aspects of cables installed in the vicinity of overhead power lines. For such applications, additional requirements and test methods can be necessary. Moreover, this document excludes optical ground wires and cables attached to the phase or earth conductors of overhead power lines. For cables for lake and river crossings, this document does not cover methods of cable repair, nor repair capability, nor does it cover cables for use with underwater line amplifiers. This fifth edition cancels and replaces the fourth edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: the ribbon specification has been removed, because it is covered in IEC 60794-1-31.
