轻型柔性引入光缆的研发与应用

受新冠疫情影响,世界各国均推出了不同程度的国家宽带计划,如FTTH、5G建设等,以刺激经济发展,为光纤网路建设带来了蓬勃发展机遇。接入网作为光纤网路建设中最复杂、灵活多变的一段线路,特别是不同国家和地区因组网布线方式、施工技能等因素影响,需采用不同的光缆技术,以达到更加方便、快捷、安全的光纤接入目的,这给光缆技术的革新带来了发展机遇。本文根据FTTH引入光缆相关标准技术、施工布线特点和工程技术要求等,研究开发了一款新型引入光缆,它具有轻型、柔性和高拉重比等特点,可满足穿管入户、自承式架空等多种敷设场景要求。

Affected by the COVID-19 pandemic,many countries have launched a series of national broadband plans,such as FTTH,5G construction,etc.,to stimulate economic development,which has brought booming development and opportunities for the construction of optical fibre networks.As the most complex and flexible section in the construction of access network,especially in different countries and regions due to the influence of networking and cabling methods,construction skills and other factors,different optical cable technology needs to be used to achieve more convenient,fast and safe optical fibre access purposes,which brings development opportunities to the innovation of optical cable technology.According to drop cable for FTTH and related standard technology,construction cabling characteristics and engineering technical requirements,this paper studies and develops a new drop cable,which is light weight,flexibility and high tensile-to-weight ratio,can meet the requirements of a variety of application scenarios such as drop installation in duct or self-supporting aerial.
