Problems solved by technology

The traditional optical cable core is a stranded structure of five units or more. The self-weight of the cable core directly affects the load-bearing capacity of the strength member. The increase in the number of cable core units increases the weight, and the load-bearing capacity of the strength member needs to be increased. The weight of the cable will also increase the manufacturing cost

Embodiment 1

[0018] Such as figure 1 As shown, a light-weight all-dielectric self-supporting optical cable includes an outer sheath 1 and a cable core. An open cable 6 is set on the inner wall of the outer sheath, which can withstand a certain pulling force and higher temperature, and realize all-weather communication. It is napped and environmentally friendly. It can easily peel off the outer sheath of the optical cable, which is convenient for construction. The cable core is composed of an optical unit 3 and two non-metal strengthening units 5SZ twisted, which reduces the diameter of the optical cable, simplifies the structure of the optical cable, and is beneficial to the structure of the optical cable Due to the light weight, high tensile strength, and low elongation of the non-metal reinforced unit, the tensile strength of the optical cable is ensured, and it is easy to lay. The optical fiber 2 is arranged in the optical unit and filled in the entire optical unit and used for In order t...

Embodiment 2

[0020] Such as figure 2 As shown, the structure is basically the same as that of Embodiment 1, the difference is that the cable core is formed by twisting two optical units 3 and a non-metallic strengthening unit 5SZ.

Embodiment 3

[0022] Such as image 3 As shown, a light-weight all-dielectric self-supporting optical cable includes an outer sheath 1 and a cable core. An open cable 6 is set on the inner wall of the outer sheath, which can withstand a certain pulling force and higher temperature, and realize all-weather communication. It is napped and environmentally friendly. It can easily peel off the outer sheath of the optical cable, which is convenient for construction.

Abstract

The invention discloses a light-duty full medium self-supporting optical cable, comprising an outer sheath and a cable core; the inner wall of the outer sheath is provided with a cable-opening pedant; the cable core consists of three units which are twisted in a SZ manner; the three units include an optical unit and two non-mental reinforcement units or two optical units and a non-mental unit reinforcement unit; and the optical unit is internally provided with optical fibers and fiber paste which is filled in the optical unit and is used for fixing the optical fibers. The invention adopts three units which are twisted in a SZ manner to form a cable core, reduces the diameter of the optical fiber, simplifies optical cable structure and benefits the miniaturization of the structure of the optical cable. The optical cable has one or two non-mental reinforcement units, which is light in weight, strong in tensile strength, small in ductility, guarantees the tensile strength, provides convenience to coating, and has a lightening resistance function. The cable-opening can bear a certain tensile force and relatively high temperature, is not easy to nap and can easily strip the outer sheath of the optical cable and provide convenience to construction.

Description

Technical field [0001] The invention relates to a light all-dielectric self-supporting optical cable used in the field of optical communication. Background technique [0002] With the continuous development of communication cable technology, there are more and more applications for optical cables. The structure of the optical cable is constantly innovating according to the needs of the application. The traditional fiber optic cable core is a stranded structure with five elements or more. The weight of the cable core directly affects the load-bearing capacity of the reinforcement. The increase in the number of cable core units will increase the weight and the load-bearing capacity of the reinforcement. The thickness of the reinforcement will increase the fiber optic cable. Because of its own weight, the manufacturing cost of the optical cable will also increase. Therefore, it is necessary to design optical cables with compact structure and light weight. Summary of the invention...
