| | According to the characteristic structure of optical fiber cables and the need for project applications,this article brings forward,from the point of view of saving project investment and easy maintenance,the theoretical bases and preventive measures for simplifying the three preventions of optical fiber communication lines. | | 本文根据光缆的结构特点和工程应用的需要,从节约工程投资和便于维护出发,提出了光缆通信线路防强电、防雷、防蚀的理论根据与防护措施。 | | 文摘来源 | | As the kinds and traffic capacity of the communication services sharply increase and fiber-to-office (FTTO) & fiber-to -home (FTTH) are gradully implemented, the fiber count and density in fiber optic cables are required to be increased. In this case, high -fiber -count ribbon optical cable has been developed in many countries. In this paper, the optical fiber ribbon technology, the optical fiber ribbon cable structure and the splicing technique are described. The development trends of the high-fiber-ribbon... | | 随着通信业务种类和容量的急剧增加以及光纤光缆逐步进入办公室和家庭,要求人们增加光缆中的光纤数量和提高光缆的光纤密度,于是大芯数光纤带叠带式光缆应远而生.本文介绍了光纤带技术、叠带式光缆的结构及接续技术,最后概述了大芯数叠带式光缆的发展动向. | | 文摘来源 | | In this paper, the structure and characteristics of ultra-thin optical fiber ribbon and 108-fiber loose tube ribbon-based cable are presented. The feasibility of using normal commercial fiber, which has 250μm coating diameter, to manufature 260μm height ultra-thin ribbon and cable is proved. The ana-lystical and experimental results of this investigation indicate that the ribbon and the cable made of these ribbons can provide good performances and it is easy to be fussion spliced. The ultra-thin ribbon has ... | | 在本文中,我们将介绍超薄型光纤带及108芯松管层绞光纤带光缆的结构和性能.表明使用涂层为250μm的常规商用光纤制造260μm高度的光纤带并由此制成光缆是可行的.本研究分析和实验表明,此光纤带和光缆具有良好的几何、光学、物理、机械性能并易接续.超薄型光纤带被成功地运用于108芯松管层绞光缆中. | | 文摘来源 | |   | | << 更多相关文摘 |
