Background
With the continuous development of network construction, the optical cable with high transmission rate and long distance is used as a data transmission medium in the comprehensive wiring system, and the utilization rate is also continuously improved. Optical cables are manufactured to meet optical, mechanical or environmental performance specifications and are telecommunication cable assemblies that utilize one or more optical fibers disposed in a covering jacket as the transmission medium and that can be used individually or in groups, and are classified into, in terms of cable core structure: central tube type optical cable, layer stranded optical cable and skeleton type optical cable. Optical fibers, a new generation of transmission media, have improved significantly in terms of security, reliability, and network performance over copper media. In addition, the bandwidth of optical fiber transmission greatly exceeds that of copper cables, and the maximum connection distance supported by the optical fiber transmission reaches more than two kilometers, so that the optical fiber transmission is a necessary choice for building a larger-scale network. And the optical fiber cable has the advantages of good electromagnetic interference resistance, strong confidentiality, high speed, large transmission capacity and the like.
The self-supporting optical cable has all the characteristics of a common optical cable, and can avoid secondary construction during erection, so that the self-supporting optical cable is increasingly applied to network construction. The self-supporting optical cable inevitably passes through multi-cross-wind and multi-ice and snow areas such as coastal areas, valleys and the like, is in a severe outdoor environment with multi-wind or multi-ice and snow for a long time, has high requirements on the quality of the self-supporting optical cable, particularly the wind resistance and the snow resistance, and the traditional self-supporting optical cable is mostly of an 8-shaped structure, and is easy to break at the middle part, so that the optical cable which is difficult to break at the middle part is needed.
