Embodiment 1

[0027] please see figure 1 with figure 2 , a wireless radio frequency remote optical cable for communication, characterized in that it consists of a central strength member 1 extruded with a plastic layer 2, an inner cushion 31 located outside the plastic layer 2, an outer cushion 4 located outside the inner cushion, and an inner cushion 4 located outside the inner cushion. The light transmission body 3 between the cushion layer and the outer cushion layer, the protective layer 5 located outside the outer cushion layer, and the outer sheath 6 coated outside the protective layer by extrusion; the inner cushion layer is close to the plastic layer, and the light transmission The body is distributed between the inner cushion layer and the outer cushion layer, and only one layer of light transmission body can be placed in the gap between the inner cushion layer and the outer cushion layer, and the protective layer is close to the outer cushion layer; the central reinforcement is m...

Embodiment 2

[0056] please see image 3 with Figure 4 , wireless radio frequency remote optical cable for communication, basic implementation example 1, the difference is: the inner cushion and the outer cushion are connected by two connecting bars 32, and the optical transmission body is located between the inner cushion and the outer cushion In the gap between them, the inner cushion layer, the connecting strip and the outer cushion layer can be integrally formed by extrusion.

[0057] Of course, it can also be the wireless remote radio cable and photoelectric composite cable as in the embodiment 1.

Embodiment 3

[0059] please see Figure 5 with Image 6 , wireless radio frequency remote optical cable for communication, basic implementation example 2, the difference is: the inner cushion and the outer cushion are connected by four connecting bars 32, and the optical transmission body is located between the inner cushion and the outer cushion In the gap between them, the inner cushion layer, the connecting strip and the outer cushion layer can be integrally formed by extrusion.

[0060] Of course, it can also be the wireless remote radio cable and photoelectric composite cable as in the embodiment 1.

[0061] Of course, the inner cushion layer and the outer cushion layer can also be connected through other multiple connecting bars, which can realize flexible distribution of optical transmission body and / or power distribution.

[0062] The wireless radio remote optical cable for communication, the radio remote remote cable or the radio radio remote photoelectric composite cable describ...

Abstract

The invention belongs to the technical field of cables, and particularly relates to a manufacturing method for a wireless radio frequency pull-far optical cable for communication. The method is characterized in that the method includes the steps of manufacturing a plastic layer, manufacturing an inner cushion layer, manufacturing an outer cushion layer and manufacturing an outer protecting bush. The invention further discloses a wireless radio frequency pull-far cable manufacturing method and a wireless radio frequency pull-far optical-electric composite cable manufacturing method. The cables have the advantages of being simple in structure, easy to manufacture, universal in the indoor environment and the outdoor environment, perfect in bending-resistant performance, softer, easier to construct and high in solar-radiation-resistant capacity. The manufacturing methods are simple and easy to master, and the percent of pass of the manufactured finished cable products is high.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a radio frequency remote optical cable for communication, a manufacturing method of an electric cable and a photoelectric composite cable. Background technique [0002] In the base station signal transmission system, the cable from the baseband unit BBU to the remote radio unit RRU is called a wireless radio cable, and the optical cable that provides signal transmission for the RRU is called a remote radio cable. The optical cable for radio frequency pull is mainly used in the local remote at the same base station, and the length is usually 100 to 300 meters. When a longer distance is required, it is advisable to use an outdoor optical cable for connection, and then connect the current end to the wireless radio remote Use fiber optic cable. Similarly, the length of the cable that provides power to the base station is generally about 200 meters. This kind of cable is c...
