Description

一种高强度光缆 技术领域
本实用新型属于线缆领域，尤其是涉及一种高强度光缆。
背景技术
随着国内5G建设的大范围推广，光缆的需求越来越大，运营商对光缆的渗水性能的需求越来越严格。
现有技术中，如CN207851365U公开的一种新型防鼠ADSS光缆，通过实用新型的材质强度较高的扁平FRP带，采用一定绞距绕包在缆芯外层，同时在FRP带外层绕包一层防水的阻水带，再由护套进行外护，做出一种全新的防鼠ADSS光缆。
上述现有技术存在如下缺憾：1.当受到较大的压力时，压力通过传导直接作用在缆芯上，影响传输性能，抗压性能不强；2.光缆维护不方便，需要破断扁平FRP带层和外护层等多个保护层，且无法替换。

上述所述的一种高强度光缆，通过在光缆外护层主体之间加入第二加强件，当光缆收到拉伸力时，第二加强件和第一加强件承受绝大部分的拉力，从而保护内部的光纤不受拉力影响，极大地增强了光缆的抗拉伸性能；第二加强件将外护层主体和内部的光通信部件围在中间，当光缆受到压力时，压力通过第二加强件，向外护层主体的顶端传导，不会影响内部光通信部件的传输性能，故第二加强件可以提供很强的抗压性能；第二加强件还可以为光缆提供定型的功能，防止外护层主体受到外力变形，而影响光缆的使用；第二加强件还提高光缆提供抗扭转的性能；第二加强件直接裸露于外，可以有效防止光缆遭到小动物的啃噬，保护内部的通信部件。

上述所述的一种高强度光缆，其特征在于所述的外护层主体材料为低密度聚乙烯或中密度聚乙烯或高密度聚乙烯或阻燃聚烯烃或聚氯乙烯。
上述所述的一种高强度光缆，其特征在于所述的光纤型号为G.652型或G.653型或G.654型或G.655型或G.656型或G.657型或A1a型或A1b型或A1c型。
上述所述的一种高强度光缆，其特征在于所述的第一加强件为磷化钢丝或不锈钢丝或玻璃纤维杆。
本实用新型中，还可以通过选取不同厚度的第二加强件，来调节光缆所能承受的最大拉力和最大压力；当第二加强件损坏时，还可以无需停止该线路的使用的情况下，替换第二加强件，方便施工，提高客户的满意度；同时损坏的第二加强件只是会降低光缆的强度而不会影响光缆的使用。
