Problems solved by technology

However, this kind of optical cable has low strength, extremely poor tensile performance, and poor moisture-proof performance of the optical cable; it is not easy to manage the optical cable when it is used in places where multi-line optical cables are laid.
The stability of the cable is poor, and the structure is prone to change during use after laying, resulting in increased loss and unstable video transmission signals

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, a high-strength and low-loss radio frequency optical cable includes a protective sheath and a biaxial optical cable inside the protective sheath, a biaxial strengthening cable and a filling material (9). The protective cover consists of an armor layer (8) and a rubber layer (7) from outside to inside. The armor layer (8) is made of anti-corrosion metal material and is in the shape of tape winding, wire winding or braiding, and has The function of anti-mechanical external force damage improves the safety of the optical cable. The rubber layer (7) can prevent the optical cable from being attacked by moisture.

[0014] The biaxial optical cable is composed of two optical cables, each optical cable is composed of a cable core, a shielding layer (3) and an outer sheath (4), and a shielding layer (3) and an outer sheath (4)...

Abstract

The invention relates to a high-strength low-loss radio frequency optical cable. The optical cable comprises a protective sheath, a double-axis optical cable body, a double-axis reinforcing cable and a filling material, wherein the double-axis optical cable body, the double-axis reinforcing cable and the filling material are arranged in the protective sheath. The protective sheath sequentially comprises an armor layer and a rubber layer from outside to inside, and the armor layer is made of anti-rust metal, is in a tape wound shape or filament wound shape or knitted shape, has the function of resisting damage caused by mechanical external force and improves user safety of the optical fiber. The optical fiber has the advantages that the strength is high, tensile strength is high, moisture resistance is good, video signal transmission performance of the optical fiber can be improved, loss is low, no toxin or pollution is caused, mechanical strength is high, structural stability, electromagnetic interference resistance and the low attenuating property of cables can be improved, multiple devices are installed, distributed and used conveniently, and line maintenance and management are convenient.

Description

Technical field: [0001] The invention relates to an optical cable, in particular to a high-strength and low-loss radio frequency optical cable. Background technique: [0002] At present, low-loss RF coaxial optical cables are mostly used for RF optical cables, and most of them are composed of inner conductors, outer conductors, insulation and sheaths. It is more convenient to install and use a single cable. However, this kind of optical cable has low strength, extremely poor tensile performance, and poor moisture-proof performance of the optical cable; it is not easy to manage the optical cable when it is used in places where multi-line optical cables are laid. The stability of the cable is poor, and the structure is prone to change during use after laying, resulting in increased loss and unstable video transmission signals. Invention content: [0003] The purpose of the present invention is to provide a high-strength and low-loss radio-frequency optical cable with high s...
