Abstract
The utility model relates to a light-weight flexible steel pipe armored optical cable which is suitable to be used in an emergency optical communication system in field environment. The structure of the light-weight flexible steel pipe armoured optical cable comprises an optical fiber unit consisting of optical fibers, a flexible steel pipe armor layer made of a soft flexible material is arranged on the outer part of the optical fiber unit, a strengthening layer is arranged on the outer part of the flexible steel pipe armor layer, the outer part of the strengthening layer is covered with an outer protection sleeve, and the flexible steel pipe armor layer has a helical structure made of stainless steel. The flexible steel pipe armored optical cable of the utility model is characterized in that soft and flexible stainless steel is wound around the optical fibers, the optical fibers are protected from affects of external mechanical stress, and the optical cable is greatly improved in mechanical performance; the optical cable is excellent in anti-compression, impact-resistance and rodent damage-resistance; the optical cable is not easy to break; the optical fibers cannot be bent, and minor bend loss can be prevented.
Description
Technical field:
The utility model relates to a kind of steel tube armour optical cable, especially relates to a kind of light flexible steel tube armour optical cable, is suitable in emergent optical communication system, using in lowered in field environment.
Background technology:
Due to the frequent generation of the disasteies such as earthquake, typhoon, tsunami, rubble flow, people in case of emergency, constantly increase the demand of optical communication system, and the market demand of field emergency optical cable is the trend of rise always.Existing field emergency optical cable is heavier, and its external diameter is generally thicker, and diameter is greatly about about 5.0mm, and weight also reaches 26kg/km left and right, for single complete this kind of optical cable to lay difficulty very large.
And because field environment very severe, the optical cable that is placed on field often can be subject to the destruction of rodent and the impact of the stone that automobile rolls and tumbles; the flexible steel pipe armored optical cable that makes the type not only can effectively be resisted the destruction of rodent but also have splendid resistance to compression and shock proof performance; this optical cable also has the little lightweight advantage of external diameter simultaneously; optical cable maximum outside diameter is 2.5mm; optical cable weight is less than 8kg/km, the single operation that lays and continue etc. that can realize field complex condition completely.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model is to overcome the defect that prior art exists, and provides a kind of external diameter little, lightweight flexible steel pipe armored optical cable, and has splendid mechanical property and environmental suitability.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of light flexible steel tube armour optical cable, comprise the fiber unit being formed by optical fiber, make flexible steel pipe armor in fiber unit outside by the flexible material of softness, described flexible steel pipe armor outside is provided with enhancement Layer, and at the outside coated one deck oversheath of enhancement Layer, the helical structure that described flexible steel pipe armor is made up of stainless steel.
Further, to contain fiber count be 2 to fiber unit.
Further, optical cable maximum outside diameter is 2.5mm.
Further, described optical fiber is the one in bare fibre, coated fiber, tightly packaged fiber.
The beneficial effects of the utility model, the utility model flexible steel pipe armored optical cable, adopt soft flexible stainless steel around fiber unit, protection optical fiber is avoided the impact of extraneous mechanical stress, greatly improve the mechanical property of optical cable, there is the destructive characteristics of splendid resistance to compression, shock resistance, anti-rodent; And not frangibility, protection optical fiber not by bending, has been avoided microbending loss.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of instructions, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Brief description of the drawings:
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1 is the schematic cross-section of the utility model flexible steel pipe armored optical cable.
Number in the figure explanation: 1, optical fiber; 2, flexible steel pipe armor; 3, enhancement Layer; 4, oversheath.
Embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to light flexible steel tube armour optical cable embodiment, structure, feature and effect thereof according to using in the utility model lowered in field environment, be described in detail as follows.
As shown in Figure 1, the light flexible steel tube armour optical cable using under a kind of lowered in field environment described in the utility model, comprises optical fiber 1, flexible steel pipe armor 2, enhancement Layer 3 and oversheath 4.
Described optical fiber 1 is the optical fiber of bending property excellence, and optical fiber can be the one in bare fibre, coated fiber, tightly packaged fiber.Described optical fiber 1 forms fiber unit by 2 optical fiber, can certainly be made up of 3 or other radicals.
Coated the outside of the 2 optical fiber 1 flexible steel pipe armor 2 of being made by the flexible material of softness.The helical structure that described flexible steel pipe armor 2 is turned to by stainless steel wire or similar material, thus protection optical fiber is avoided the impact of extraneous mechanical stress, improves the mechanical property of optical cable.
Described enhancement Layer 3 is evenly distributed on around flexible steel pipe armor 2; Described enhancement Layer 3 is aramid fiber, has high-modulus, high strength feature.
Described oversheath 4 is made up of any one or various material in tygon, Polyvinylchloride, low smoke halogen-free flame-retardant polyolefin, polyurethane, nylon, polypropylene, Teflon, squeezes the outside at enhancement Layer 3.
According to the above description, the utility model optical cable is compared with field optical cable in the market: have external diameter little, its optical cable maximum outside diameter can be 2.5mm.The physics lightweight, operating temperature range is wide, splendid and mechanical property, have that resistance to rodent is destroyed and excellent lateral pressure resistant performance, processing and fabricating is easy, and cost performance high has extremely strong market competition advantage.
Below be only that this uses novel concrete exemplary applications, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
