Problems solved by technology

[0004] There are following shortcomings in the above-mentioned prior art: 1. The weight of the optical cable is large, and materials such as steel wire armor and annular ribs are arranged inside the optical cable, which increases the weight of the optical cable and brings inconvenience to the construction; 2. The rubber cushion is distributed in adjacent Between loose tubes, adjacent filling ropes, and between loose tubes and filling ropes, it cannot provide compression and earthquake protection between loose tubes and central reinforcements, loose tubes and outer sheaths

Abstract

The invention belongs to the field of cables and particularly relates to a special-shaped filling rope. The cable is provided with an outer protective layer, a belting layer, a central reinforcing member and at least three loose tubes, wherein at least one optical communication component is arranged in each loose tube, the cable is characterized in that a filling rope is further arranged between every two adjacent loose tubes, the filling rope is composed of a base and two branched supporting plates located at the top of the base, an accommodating cavity is formed between the two support plates towards the inside of the base, an embedding opening is formed in the top of the accommodating cavity, the bottom of the base is arc-shaped and is attached to the surface of the central reinforcingpiece, the base of the previous filling rope, the supporting plate on the left side and the base of the next filling rope are close to each other in the clockwise direction to form an oval loose tubecontaining cavity, the loose tube is located in the loose tube containing cavity, and an electric unit is arranged in the containing cavity. The cable has advantages of being simple in structure, goodin heat dissipation performance, resistant to side pressure, shock and torsion, easy to construct and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to an optical cable with special-shaped filling ropes. Background technique [0002] With the large-scale promotion of domestic 5G construction, the demand for optical cables is increasing. In some complex environments, optical cables require strong compression performance. [0003] In the prior art, as CN207249204U discloses a kind of explosion-proof optical cable for mining, it is characterized in that: comprise outer sheath, steel wire armoring is installed in described outer sheath, described outer sheath and steel wire armor cross section They are all circular and tightly connected. A central reinforcement is installed inside the steel wire armor, and several loose tubes are installed between the outer surface of the central reinforcement and the inner surface of the steel wire armor. A number of loose tubes and a number of filling ropes are installed between the outer surface of the cen...
