Abstract
The utility model discloses a tube cable is restrainted at single mode center, including the cable core, the cable core wraps up outward in proper order has loose sleeve pipe layer, water blocking material layer, plastic -coated steel strip and pe sheath layer, pe sheath in situ parcel have parallel arrangement's wire -core line, loose sleeve pipe layer adopt polypropylene materials to make. The utility model discloses simple structure has good anti tide, the hydrolytic resistance ability of passing through to mechanical strength is good.
Description
Technical field
The utility model relates to optical cable technology field, especially a kind of single mode central-beam tube type fiber optic cable.
Background technology
Optical cable is the prevailing transmission instrument of the various Information Network of current information society, in order to meet the performance specification of optics, machinery or environment, utilizes one or more optical fiber being placed in coated sheath also can use separately or in groups as transmission medium.
Outdoor optical cable faces various unpredictable external environment, for outdoor optical cable, not only requires to ensure that contact usually, more requires that optical cable has good anti-moisture vapor transmission, anti-hydrolytic performance, and have certain physical strength.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, has good anti-moisture vapor transmission, anti-hydrolytic performance, and the single mode central-beam tube type fiber optic cable that physical strength is good.
The utility model solves the technical scheme that its technical matters adopts: a kind of single mode central-beam tube type fiber optic cable, comprise cable core, cable core is enclosed with Loose tube layer, material water-proof material layer, Clad Steel belt and pe sheath layer outward successively, be enclosed with the wire cored wire be arranged in parallel in described pe sheath layer, described Loose tube layer adopts polypropylene material to make.
Further, cable core comprises the sleeve pipe filler layer of painted coated fiber and parcel optical fiber.
Further, wire cored wire quantity is two.
The beneficial effects of the utility model are: the utility model structure is simple, have good anti-moisture vapor transmission, anti-hydrolytic performance, and physical strength is good.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
The painted coated fiber 7. sleeve pipe filler layer of 1. Loose tube layer 2. material water-proof material layer 3. Clad Steel belt 4. pe sheath layer 5. wire cored wire 6. in figure
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of single mode central-beam tube type fiber optic cable as shown in Figure 1, comprises cable core, and cable core is enclosed with Loose tube layer 1, material water-proof material layer 2, Clad Steel belt 3 and pe sheath layer 4 outward successively, is enclosed with the wire cored wire 5 be arranged in parallel in described pe sheath layer 4.Wire-core 5 line quantity is two.Cable core comprises the sleeve pipe filler layer 7 of painted coated fiber 6 and parcel optical fiber.
Loose tube layer 1 adopts polypropylene material to make, and can optical fiber be protected from internal stress and outer side pressure influence by available protecting.Sleeve pipe filler layer 7 can be extraordinary ointment, can carry out special type protection to internal optical fiber.Clad Steel belt 3 improves the anti-moisture vapor transmission ability of optical cable.Two wire cored wires 5 be set in parallel in pe sheath layer effectively can ensure the tensile strength of optical cable, make optical cable meet outdoor laying demand.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
