Full-medium self-supporting micro-beam tube ADSS optical cable

Abstract

The invention discloses a full-medium self-supporting micro-beam tube ADSS optical cable. The optical cable comprises an optical fiber bundle micro-beam tube body,a water stop tape layer and an outersheath which are sequentially arranged from inside to outside. The optical fiber is characterized in that the optical fiber bundle micro-beam tube body comprises optical fiber bundles and a micro-beamtube main body wrapping the optical fiber bundles,and the micro-beam tube main body is made of a thermoplastic polyester elastomer material; a full-dry water stop material is filled between the optical fiber bundles in the micro-beam tube main body. The full-medium self-supporting micro-beam tube ADSS optical cable can still guarantee a small outer diameter and a low optical fiber weight under the condition that the optical fiber density is high and the capacity is large,the optical cable connection time can be shortened by 50% or above,and the optical fiber has the advantages of being smallin size,easy to strip,easy to separate,low in weight,full in section and free of water seepage.

Description

technical field [0001] The invention belongs to the technical field of communication optical cable manufacturing, and in particular relates to an all-dielectric self-supporting micro-bundle tube ADSS optical cable. Background technique [0002] A smart city is a new model of urban development that makes full use of modern information and communication technology, gathers the wisdom of people, and endows things with intelligence, so that people who gather wisdom and things with intelligence can interact and complement each other, so as to realize the optimization of economic and social activities. and new forms. With the demand background of the large-scale construction of smart cities, the technical architecture of smart cities covers the perception layer, network layer and application layer. The data transmission requirements of a large number of collection nodes in the perception layer need to be met by a high-speed, broadband, integrated, and wireless network layer. New ...

Problems solved by technology

[0004] like figure 1 , 2 Shown is a traditional all-dielectric self-supporting micro-tube ADSS optical cable, the cable core is as follows figure 1 The layer-stranded structure shown and as figure 2 In the central tube structure shown, the common characteristics of the two types of optical cables are large outer diameter and heavy weight, and the load of wind speed and ice coating in the external environment will also increase, and the overall cost of optical cable construction is high.

[0005] On the other hand, most of the traditional all-dielectric self-supporting microtube ADSS optical cables are waterproofed by filling ointment. When the optical cable filled with ointment needs to be cleaned when it is connected, a cleaning agent must be used to clean the cable core and optical fiber. Cleaning, especially when working indoors, the process is time-consuming and pollutes the environment; moreover, the process of filling ointment in the production process of optical cables is not easy to control, and it is easy to foam
