Embodiment 1

[0064] please see Figure 7 , and refer to Figures 1 to 6 , an optical fiber ribbon cable, which consists of a loose tube 3, a water-blocking layer 4 outside the loose tube, an armor layer 6 outside the water-blocking layer, two strengthening members 5 outside the armor layer, and The outer sheath 7 covered by the armor layer and the strengthening member is composed of an outer sheath 7; it is characterized in that the loose tube 3 includes an optical fiber ribbon body and a loose tube body 2 that covers the optical fiber ribbon body, and the optical fiber The ribbon body is composed of an optical fiber ribbon laminate and optical fiber ribbons 1 located on the left and right sides of the optical fiber ribbon laminate. The optical fiber ribbon laminate is formed by stacking multiple optical fiber ribbons 1 up and down in sequence; The apex of the rectangle is in contact with the inner wall of the loose tube body or has a slight gap; the length of the optical fiber ribbon is ...

Embodiment 2

[0066] please see Figure 8 , and refer to Figures 1 to 6 , an optical fiber ribbon cable, which consists of a loose tube 3, a water-blocking layer 4 outside the loose tube, an armor layer 6 outside the water-blocking layer, four reinforcements 5 outside the armor layer, and the armor The outer sheath 7 covered by the coating layer and the strengthening member is composed of an outer sheath 7; it is characterized in that the loose tube 3 includes an optical fiber ribbon body and a loose tube body 2 that wraps the optical fiber ribbon body, and the optical fiber ribbon The body is composed of an optical fiber ribbon laminate and optical fiber ribbons 1 located on the left and right sides of the optical fiber ribbon laminate. The optical fiber ribbon laminate is formed by stacking multiple optical fiber ribbons 1 up and down in sequence; And the apex of the rectangle is in contact with the inner wall of the loose tube body or has a slight gap; the length of the optical fiber r...

Embodiment 3

[0085] please see Figure 9 , and refer to the comparison Figure 1 to Figure 6, an optical fiber ribbon cable, which consists of a central strength member 5, four loose tubes 3 distributed outside the strength member in an SZ twisted manner, and peripheral filling ropes 8 located in the outer gaps of adjacent loose tubes 1. The outer sheath 6 covered by the outer filling rope and the loose tube, and the outer sheath 7 coated outside the armor layer by extrusion; the loose tube and the outer filling rope are tangent to the inner edge of the armor layer It is characterized in that the loose tube 3 includes an optical fiber ribbon body and a loose tube body 2 that covers the optical fiber ribbon body, and the optical fiber ribbon body is composed of an optical fiber ribbon laminate and is located on the left and right sides of the optical fiber ribbon laminate. The optical fiber ribbons 1 on both sides are formed, and the optical fiber ribbon laminate is formed by stacking mult...

Abstract

The invention relates to the technical field of fiber cables, in particular to a method for manufacturing a fiber ribbon cable. The method includes the steps of manufacturing a fiber ribbon, manufacturing a loose sleeve, manufacturing a waterproof layer, manufacturing an armor layer and manufacturing an outer sheath, or includes the steps of manufacturing a fiber ribbon, manufacturing a loose sleeve, conducting twisting to form a cable core, manufacturing an armor layer and manufacturing an outer sheath. The invention further discloses a structure of the fiber ribbon cable. The fiber ribbon cable has the advantages that the structure is more compact, the outer diameter is smaller, needed discs are more economical, the weight is lighter, the transportation cost is lower, consumed raw materials are fewer, the comprehensive cost is lower, and the fiber ribbon cable is easy to manufacture.

Description

technical field [0001] The invention relates to the technical field of optical fiber cables, in particular to an optical fiber ribbon cable and a manufacturing method thereof. Background technique [0002] With the rapid development of the communication industry, the demand for fiber optic cables is increasing. Loose tubes are used in the current center-bundle tube-type ribbon cables, and multiple optical fiber ribbons are placed in the loose tubes. This method achieves a higher density. There are more detailed regulations in "Fiber Ribbon Cables for Networks Part 3 Stranded Type" and the Communication Industry Standard of the People's Republic of China YD / T 981.2 "Fiber Ribbon Cables for Access Networks Part 3 Central Tube Type". [0003] Among them, the loose tube 3 used is as figure 1 As shown, a plurality of optical fiber ribbons 1 are stacked to form a laminate, and then put into the loose tube 3, of course, the wall 2 of the loose tube has a certain thickness, figu...
