Embodiment Construction

[0018] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] control figure 1 , the tight-buffered optical cable provided by the present invention includes an outer sheath 1, a strength member 2, an optical fiber 4, an inner sheath 3 and two copper wires 5, and the strength member 2 used in this embodiment is a sheet-shaped aramid ribbon, ensuring The tight-packed optical fiber 4 is small in size and light in weight. The inner sheath 3 is arranged at the central axial position of the outer sheath 1 , and the central axial position of the inner sheath 3 is provided with an optical fiber 4 . An aramid ribbon is arranged between the outer sheath 1 and the tight sleeve optical fiber 4 . The copper wires are evenly distributed on the inner circumference of the outer sheath 1 . The copper wire 5 is used as a feedback line, and one end of the copper wire 5 is connected to an alarm bell. The surface of the co...

Abstract

The invention relates to a tightly sleeved optical cable and a mold thereof. The optical cable comprises an outer sheath, a reinforcing piece, an optical fiber, an inner sheath and at least two copper wires, wherein the inner sheath is sleeved inside the outer sheath, the optical fiber is arranged in the inner sheath, the reinforcing piece is arranged between the outer sheath and the tightly sleeved optical fiber, and the copper wires are uniformly distributed on the inner circumference of the outer sheath. The tightly sleeved optical cable and the mold have the advantages that the optical cable can carry out intelligent node positioning, and maintenance expenses are reduced; compared with indoor optical cable used conventionally, stress in bending is uniform; tensile strength is good; and the mold adopts a fish mouth type eye mold, production quality can be well guaranteed, fiber cut easily produced in the production process is avoided, and the two copper wires are effectively positioned.

Description

technical field [0001] The invention belongs to the field of optical fiber communication and manufacture, and in particular relates to a tight sleeve optical cable and a mold thereof. Background technique [0002] With the development of FTTH, the amount of indoor optical cables is increasing year by year. As a mature product, tight-buffered optical cables are widely used. The wiring in buildings is like a spider web. In the later maintenance, the existing optical fibers lack signal feedback and the nodes can only With the positioning function, it is difficult for maintenance personnel to find another node from one node of the optical fiber, which is not conducive to finding the fault point, which increases the time for troubleshooting and increases the maintenance cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above prior art, and provide a tight-sleeved optical cable and its mold that can intelligently...
