光缆.第5部分:分规范.充气式安装微型电缆

[中文适用范围]： IEC 60794@的这一部分是分规范@，规定了室外和/或室内使用的吹装微管光纤电缆@微管光纤单元@微管和受保护微管的要求。微管光缆和微管光纤单元利用微管或受保护微管的结构来支持安装并在设计寿命期间提供保护。这些产品可用于通信和传输网络@传输@电话和数据处理设备@控制和监测应用等应用。本分规范中描述的布线结构经过独特设计，可通过吹入微管道来促进和利用安装。 IEC TR 62839-1 给出了在需要时构建环境声明@的规则。 [外文原描述]： IEC 60794-5:2014 which is a sectional specification, specifies the requirements of microduct optical fibre cables, microduct fibre units, microducts and protected microducts for installation by blowing for outdoor and/or indoor use. The microduct optical fibre cables and microduct fibre units utilize the structure of the microduct or protected microducts to support installation and to provide protection over the design lifetime. These products may be used for applications such as communication and transmission networks, transmission, telephone and data processing equipment, control and monitoring applications. The cabling structures described in this sectional specification are uniquely designed to facilitate and take advantage of installation by blowing into microducts. This second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the addition of constructional requirements, including a reference to IEC 60794-3 for microduct optical fibre cables; - the specification has been streamlined by cross-referencing IEC 60794-1-1. Keywords: microduct optical fibre cables, microduct fibre units, microducts and protected microducts, installation by blowing
