Abstract
The invention relates to a novel parallel steel wire center beam tube ribbon optical cable, which comprises optical fibers positioned at the center of a loose tube, wherein a filler is arranged in the loose tube, and a steel strip is arranged outside the loose tube; a water-blocking filler is filled between the loose tube and the steel strip, and a sheath is arranged outside the steel strip; four steel wires are arranged in the circumference of the sheath and are uniformly distributed in the sheath, and optical fibers are arranged and bonded into a strip shape, and a plurality of optical fiber strips are superposed into a superposed body; and the surface of the steel strip is provided with wrinkles. Compared with the structure before improvement, the structure can greatly reduce the diameter of the optical cable and save resources of city underground pipelines; or when the external diameters of the optical cables are the same, the structure can greatly increase the number of the optical fibers in the optical cable and provide optical communication services for more users.
Description
Technical field
The present invention relates to a kind of optical fiber ribbon cable, especially relate to a kind of center beam tube ribbon optical cable that parallel steel wire is arranged.
Background technology
Along with coming of information age, the conveying capacity of information increases rapidly.As the effective means that high capacity, long distance transmit, optical fiber cable has obtained a large amount of application.The application of optical cable is also developed to Metropolitan Area Network (MAN), Access Network direction by long distance line gradually.The development of industry is promoting development of technology, and new cable configuration is constantly released, and new technology constantly is applied.Existing central beam pipe optical cable adopts both sides respectively to place a parallel steel wire as reinforcement, and gauge of wire is excessive, and jacket thickness is also excessive, has caused the diameter of whole piece optical cable excessive.
Summary of the invention
Technical matters to be solved by this invention provide a kind of can be by reducing the novel parallel steel wire center beam tube ribbon optical cable that gauge of wire and jacket thickness reduce the diameter of whole piece optical cable.
The present invention solves the technical scheme that its technical matters takes: a kind of novel parallel steel wire center beam tube ribbon optical cable, comprise optical fiber, optical fiber is positioned at pine cover tube hub, in the pine sleeve pipe sleeve pipe filling material is arranged, there is steel band the outside of pine sleeve pipe, is filled with the filling material that blocks water between loose sleeve pipe and steel band, in the outside of steel band sheath is arranged, both sides in sheath are provided with steel wire, and described steel wire respectively has at least two on the both sides of sheath.
For the speed that continues that makes optical fiber improves and the increase density of optic fibre, described optical fiber arrangements becomes band, and many fibre ribbons are overlapped into a superimposed body.
Separate for steel band being can be good at contacting and be not easy with sheath, and make optical cable be easy to bending, described steel strip surface has wrinkle.
Advantage of the present invention is: compare with improving pre-structure, this structure can reduce the diameter of optical cable significantly, saves the urban Underground pipeline resource; Perhaps when cable outer diameter is identical, can improve the quantity of optical fiber in the optical cable greatly, can provide the optical communication business for more user.

Embodiment
As Fig. 1 is the prior art constructions synoptic diagram, comprise optical fiber 1, optical fiber 1 is positioned at loose sleeve pipe 3 centers, in the pine sleeve pipe 3 sleeve pipe filling material 2 is arranged, there is steel band 5 outside of loose sleeve pipe 4, is filled with the filling material 4 that blocks water between loose sleeve pipe 3 and steel band 5, in the outside of steel band 5 sheath 6 is arranged, both sides in sheath 6 are provided with steel wire 7, unlike the prior art be as shown in Figure 2, described steel wire 7 four steel wires that around sheath 6, evenly distribute.In order to improve the speed that continues of optical fiber 1, optical fiber 1 is arranged in band shape, and the surface of steel band 5 has wrinkle better to combine with sheath 6, and improves the optical cable bending property.The parallel steel wire 7 that a parallel steel wire 7 formula central beam pipe racks cables adopt two Φ 1.8 is respectively placed in former both sides, general assembly (TW) is 39.7 kilograms/kilometer, four parallel steel wires 7 evenly distribute around now adopting, adopt four Φ 1.2 parallel steel wires 7, general assembly (TW) is 35.2 kilograms/kilometer, compares saving steel wire 7 and can reach 11%; Sheath 6 external diameters reduce 5% on year-on-year basis, adopt four steel wires 7 can reduce the diameter of optical cable, but but do not reduce the mechanical property of optical cable, save material, reduce the optical cable cost, improve the performance of enterprises, when cable outer diameter is identical, can improve the quantity of optical fiber in the optical cable greatly, can provide the optical communication business for more user.
