Problems solved by technology

[0002] In recent years, with the rapid development of 5G networks and the application of big data and artificial intelligence, the construction of base stations has entered a blowout development, and various base stations have been densely deployed. The characteristics of all media have been widely used, but with the increasingly complex laying environment, especially in the construction near hills, forests and lakes, the existing products are resistant to tension, water resistance, rat bite and impact resistance, etc. There are defects in the characteristics, and there is an urgent need for a remote optical cable for integrated wiring

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, the present invention is a remote optical cable, including a positioning framework 14 located in the center of the cable, and supporting frameworks 9 are arranged symmetrically along the four corners of the positioning framework, and circular grooves are formed between the positioning framework and each supporting framework. Place the sub-cable in the circular groove to form a cable core; the inner sheath 1 is extruded outside the cable core, the inner sheath is woven with an aramid yarn braiding layer 12, and the outer sheath 13 is extruded outside the aramid yarn braiding layer; The sheath, the braided layer of aramid yarn and the outer sheath are integrally formed. The sheath material has the property of preventing rat bites. The 360° wrapping of the braided layer of aramid not only improves the tensile perf...

Abstract

The invention provides a remote optical cable and a preparation method thereof. The remote optical cable comprises a positioning skeleton located in the center of the cable, supporting skeletons are symmetrically arranged along the four corners of the positioning skeleton respectively, a circular groove is formed between the positioning skeleton and each supporting skeleton, and sub-cables are placed in the circular grooves to form a cable core; an inner sheath is extruded outside the cable core, an aramid yarn braid layer is woven outside the inner sheath, and an outer sheath is extruded outside the aramid yarn braid layer; and the inner sheath, the aramid yarn braid layer and the outer sheath are integrally formed. According to the invention, a skeleton supporting form is adopted, so that the roundness of a product is improved, and the phenomena of large attenuation and even fiber breakage caused by adhesion are avoided; according to the invention, effective optimization is carried out on the premise that the original characteristics of light weight, small bending radius, full medium and the like of the product are ensured, and tensile strength, water resistance, rat bite resistance, impact resistance and pressure resistance are respectively added and optimized, so that the laying range and the comprehensive laying capability of the product are improved.

Description

technical field [0001] The invention relates to the field of communication cables, in particular to a remote optical cable and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of 5G networks and the application of big data and artificial intelligence, the construction of base stations has entered a blowout development, and various base stations have been densely deployed. The characteristics of all media have been widely used, but with the increasingly complex laying environment, especially in the construction near hills, forests and lakes, the existing products are resistant to tension, water resistance, rat bite and impact resistance, etc. There are defects in the characteristics, and there is an urgent need for a remote optical cable for integrated wiring. Contents of the invention [0003] In order to solve the existing problems, the present invention provides a remote optical cable, which not only improves the te...
