带状光缆的结构设计及测试

Design & test of ribbon optical fiber cables

通信网的建设正从骨干网建设转向城域网和接入网建设,大量需求大芯数小尺寸的带状光缆。为了制造出能承受各种受力和耐受温度大范围变化而传输性能稳定的带状光缆,结构和参数设计是关键。本文分析了层绞式和中心束管式带状光缆的结构设计诸要素,详细探讨了光缆结构的设计计算方法,给出了两种光缆的设计实例,并给出了拉伸试验的结果。

Construction of communication network has been transferring from core network to WAN and access network, so, ribbon optical cables that have large number of fibers and small size are needed generously. The construction design for two types of ribbon fiber cable, include central loose tube ribbon fiber cable and layer stranded ribbon fiber cable, are explored. By analyzing the affecting factors of tensile performance, the calculation methods of construction for two types of cables are discussed in detail, and examples are given. At last, the paper shows the tensile test results.
