国内外低摩擦光缆的研究现状及其相关标准探讨

Research Status of Low-Friction Optical Cable at Home and Abroad and Related Standards

近年来光纤到户(FTTH)进入快速发展阶段,对城市管网资源提出了更多的需求。但是新建管网势必会大幅增加敷设成本,因此在有限的空间内最大限度地利用现有管网资源就显得尤为重要。在此背景下,低摩擦光缆应运而生,其产品主要包括用于室内FTTH引入的蝶形光缆、管道光缆、气吹光缆等。国内外的光缆生产厂家都对低摩擦光缆进行了研究,从结构或材料方面优化改进产品。对国内外低摩擦光缆的研究现状以及相关测试标准进行简要概述。

In recent years,fiber to the home(FTTH)has entered a rapid development stage,which puts forward more demands for urban pipeline network resources.However,the cost of laying new pipeline networks is bound to increase dramatically,so it is particularly important to maximize the use of existing pipeline network resources in limited space.In this context,low-friction optical cables emerge as the times require.Their products mainly include bow-type optical cables,pipeline optical cables and air-blown optical cables for indoor FTTH access.Domestic and foreign cable manufacturers have studied low-friction optical cables.Some have optimized their products in terms of structure and some have improved their products in terms of materials.The research status of low-friction optical cable at home and abroad and related test standards are briefly summarized.
