Abstract
The invention relates to a pipe type round introduction optical cable which comprises an optical fiber located at the center of the whole optical cable. An optical fiber tight sleeve layer is arranged outside the optical fiber, nonmetal reinforcing yarn is extruded outside the optical fiber tight sleeve layer, a low smoke zero halogen outer sheath is in extrusion molding outside the nonmetal reinforcing yarn, a waterproof layer is further arranged outside the low smoke zero halogen outer sheath, and an aluminum polyethylene sheath is arranged outside the waterproof layer. The pipe type round introduction optical cable has the advantages that a round introduction optical cable with the tensile strength of 500N serves as an independent component of the pipe type round introduction optical cable, and when the aluminum polyethylene sheath and a water-blocking tape are stripped, the round introduction optical cable can serve as a home-entry optical cable; a water-blocking object is added in the pipe type round introduction optical cable, and the optical cable can block water in a total cross section mode; the waterproof layer and the aluminum polyethylene sheath are added outside the indoor and outdoor round introduction optical cables, and the optical cable can block water in a total cross section mode and can be laid in different scenes such as pipes, outdoor aerial scenes and indoor scenes.
Description
Technical field
The present invention proposes a kind of communications optical cable manufacturing technology, relates in particular to the circular leading in cable of a kind of pipeline type.
Background technology
During the light net is built at present, existing duct optical cable product G YTA type and indoor and outdoor GJYXFH03 type optical cable, in use mainly there is following problem: when adopting GYTA type optical cable to carry out pipeline laying, contain the material that fine cream, cable cream etc. easily pollute in optical cable, the use of can not registering one's residence, large, the Heavy Weight of the external diameter of optical cable, cost compare are high simultaneously; When adopting GJYXFH03 type optical cable to carry out pipeline laying, can use in indoor and outdoor.There is no moisture-proof layer in its structure, vertical waterproof can not guarantee serviceable life of optical cable in the pipeline of humidity, the optical cable of registering one's residence after simultaneously the PE sheath being divested is butterfly optical cable, because there is structural defective in the butterfly leading in cable, therefore can't guarantee product quality.
Summary of the invention
But the circular leading in cable of the pipeline type that the present invention seeks to for and provide a kind of total cross-section to block water to be convenient to lay.
For achieving the above object, the present invention solves the scheme that its technical matters takes and is:
The circular leading in cable of this pipeline type, comprise the optical fiber that is positioned at whole optical cable center, described optical fiber is outside equipped with the optical fiber tight sleeve layer, described optical fiber tight sleeve layer is extruded with nonmetal reinforcement yarn outward, the outer extrusion molding of described nonmetal reinforcement yarn has the low smoke and zero halogen oversheath, described low smoke and zero halogen oversheath also is provided with water blocking layer outward, and described water blocking layer is outside equipped with the aluminumpolyethylene sheath.
In order to reach the comprehensive effect that blocks water, further, be provided with water-blocking material in the nonmetal reinforcement yarn of described row.
Compared with prior art, usefulness of the present invention is: the circular leading in cable of this pipeline with the circular leading in cable of tensile strength 500N as independent member of the circular leading in cable of pipeline type, after it divested aluminumpolyethylene sheath and waterstop, circular leading in cable can be used as indoor optical cable and uses; Design has increased water-blocking material in the circular leading in cable of pipeline type, but the optical cable total cross-section blocks water; Increased water blocking layer and aluminumpolyethylene sheath in the design of the outside of the circular leading in cable of indoor and outdoor, but the optical cable total cross-section block water, can lay in pipeline, outdoor aerial, the different scenes such as indoor.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the circular leading in cable structural representation of pipeline of the present invention.
In figure: 1, optical fiber; 2, optical fiber tightly overlaps; 3, nonmetal reinforcement yarn; 4, low smoke and zero halogen oversheath; 5, water blocking layer; 6, aluminumpolyethylene sheath; 7, water-blocking material.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments:
The circular leading in cable of a kind of pipeline shown in Figure 1, comprise the optical fiber 1 that is positioned at whole optical cable center, described optical fiber 1 is outside equipped with the tight cover 2 of optical fiber, be extruded with nonmetal reinforcement yarn 3 outside the tight cover 2 of described optical fiber, the outer extrusion molding of described nonmetal reinforcement yarn 3 has low smoke and zero halogen oversheath 4, described low smoke and zero halogen oversheath 4 is outer also is provided with water blocking layer 5, and described water blocking layer 5 is outside equipped with aluminumpolyethylene sheath 6, is provided with water-blocking material 7 in the nonmetal reinforcement yarn 3 of described row.
As independent member of the circular leading in cable of pipeline type, after it divested aluminumpolyethylene sheath and waterstop, circular leading in cable can be used as indoor optical cable and uses the circular leading in cable of this pipeline with the circular leading in cable of tensile strength 500N; Design has increased water-blocking material in the circular leading in cable of pipeline, but the optical cable total cross-section blocks water; Increased water blocking layer and aluminumpolyethylene sheath in the design of the outside of the circular leading in cable of indoor and outdoor, but the optical cable total cross-section block water, can lay in pipeline, outdoor aerial, the different scenes such as indoor.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
