Abstract

本实用新型是一种超强型束管式光缆,属于光纤 通信技术领域。由于在束管外采用梯形钢丝加强件, 成缆时束管不受任何扭力和侧压力,绞合后成拱形 状,极大地提高了光缆的抗侧压强度。与圆形钢丝相 比,在不增加光缆外径的条件下,加大了钢丝的截面 积,有效地提高了光缆的抗拉强度。该光缆可容纳 4-48芯光纤,适用于长途干线光缆通信系统。

Description

本实用新型是一种超强型束管式光缆,适用于光纤通信。
束管式光缆是近年出现的新型结构光缆,其结构合理,密封性好,性能价格比高,极有发展前途。目前,较为典型的有:
(A)美国AT&T公司的LXE型。
(B)日本Ocean  Cable  Co.的SM-6-ST-WAZE型。
其中(A)能容纳较多的光纤芯数,但因没有金属保护层,加强元件较少,故机械性能较差;(B)采用钢管外绞合钢丝复合装铠,虽提高了机械强度,但由于弯曲和侧压的限制,不可能做得很大,光纤芯数受到限制,只能做到6芯以下。
本实用新型的目的是,提供一种高抗侧压强度、高抗拉强度、光纤芯数能满足干线通信需求的新型光缆。
超强型束管式光缆是由缆芯、外层加强件、外护套组成。其加强件为梯形钢丝,绞合后成拱形状。
本实用新型的优点是,由于加强件采用梯形钢丝装铠,成绞后成拱形,极大地提高了光缆的抗侧压强度;与圆形钢丝相比,在不增加光缆外径的同时,加大了钢丝的有效面积,提高了光缆的抗拉强度;容纳光纤芯数多。根据国外文献报导具体数据如下:
光缆类型    抗拉强度    抗侧压强度
LXE    680N    4540N
SM-6-ST-WAZE    1000N    3500N
超强型    6000N    6000N

结合附图对本实用新型作进一步说明:
超强型束管式光缆图1,它由光纤1、石油膏2、束管3构成的缆芯,外层加强件4和外护套5组成。缆芯外的加强件采用梯形钢丝,绞合后成拱形状,在其外为外护套5。外护套5为聚乙烯,由挤塑机挤出。超强型束管式光缆最多可容纳48芯,其缆芯由二次被敷设备生产。
