Abstract
This invention relates to a kind of pipeline mapping optical cable , the optical cable includes the outside jacket, fiberglass reinforces plastic hinder water belt suspended type optical cable core, whose characteristic depends on that the suspended type optical cable core has 8 shape cross section outline , it is composed of the inside jacket and two reinforcing piece and optical fiber in the inside jacket, The two reinforcing pieces are located in the center of two circle of the 8 form cross section , the optical fiber is located in the center of the 8 shape cross section, using the inside jacket which is made of Geon PVC or low smoke no halogen plastic LSZH material packs the optical fiber and two reinforcing pieces into 8 shape outside outlines; the fiberglass sharpening plastic and the suspended type optical cable core in the two sides of 8 shape cross section are packed together by hinder water belt, whose outside pack with back polyethylene PE or the person or low smoke no halogen plastic LSZH material circle cross section jacket.
Description
Technical field
The present invention relates to a kind ofly be incorporated into the optical cable of ONT Optical Network Terminal in the buildings, or rather, the present invention relates to a kind of pipeline projection optical cable from yard piping.
Background technology
Along with the development of Fiber to the home (FTTx) mode, the status of leading in cable is more and more important, and leading in cable has been taken into account the characteristics of outdoor optical cable and inside cable, and is simple and practical.Present most of leading in cable adopts ointment to fill or the half dry type structure, brings certain difficulty for the construction cleaning; And also to and join fibre after optical cable is incorporated in the building, increase construction link and engineering cost through separated time once more.
Summary of the invention
The object of the present invention is to provide a kind of pipeline projection optical cable.The pipeline projection optical cable that this optical cable is a kind of dry type, connect one to one by pipeline laying mode and ONT Optical Network Terminal (ONT) from outdoor distribution point.
A kind of pipeline projection optical cable that the present invention relates to, comprise oversheath 1, Fibreglass Reinforced Plastics 2, waterstop 3, suspension type optical cable core 5, it is characterized in that suspension type optical cable core 5 has the cross section profile of 8 fonts, form by inner two reinforcements 7 of inner sheath and inner sheath and optical fiber 4, two reinforcements 7 are positioned at 8 shaped sections, two circular central positions, optical fiber 4 is positioned at 8 shaped sections centers, inner sheath by polyvinylchloride or low smoke and zero halogen plastics LSZH material is rolled into integrally formed 8 font outlines with optical fiber 4 and two reinforcements 7, constitutes suspension type optical cable core 5 thus.
Fibreglass Reinforced Plastics 2 lays respectively at outside the 8 shaped sections waist both sides of suspension type optical cable core 5.
Suspension type optical cable core 5 is bundled together the circular cross-section of formation rule with the Fibreglass Reinforced Plastics 2 of both sides by waterstop 3.
Round section oversheath 1 at waterstop 3 outsides parcel black polyethylene PE or low smoke and zero halogen plastics LSZH material.
Pipeline projection optical cable of the present invention, waterstop is outer can to have the yarn of bundle to tie up, and can be provided with between waterstop 3 and oversheath 1 and spin the synthetic fibre yarn or tear rope 6.
Reinforcement 7 in the described suspension type optical cable core 5 is made of steel wire or Fibreglass Reinforced Plastics FRP.
8 shaped sections profiles of described suspension type optical cable core 5 are to write or the figure of eight that electronic clock shows.
It is the light unit that pipeline projection optical cable of the present invention adopts the suspension type optical cable core, avoids the use of ointment, is convenient to the optical cable skin simultaneously and peels off light unit, back and also possess the sufficient intensity use that terminates; . adopt tiny NAG Fibreglass Reinforced Plastics to be distributed in the minor axis both sides of suspension type optical cable, just in time constitute a similarly circle with the suspension type optical cable core; By the waterstop mode loose suspension type optical cable core and Fibreglass Reinforced Plastics are rolled into regular circular; Waterstop is outer can to have the yarn of bundle to tie up, and can be provided with to spin the synthetic fibre yarn or tear rope to be convenient to optical cable construction.
Beneficial effect:
1. utilize unique waterstop to guarantee that the optical cable total cross-section blocks water; 2. Fibreglass Reinforced Plastics FRP, suspension type optical cable core and optionally spin the synthetic fibre yarn and provide guarantee for the mechanical property of optical cable; 3. oversheath is opened stripping easily, opens that suspension type optical cable core after the stripping is convenient to be used separately; 4. optical cable temperature performance, fire resistance are good.
Description of drawings
Fig. 1 is an optical cable sectional view of the present invention.
Embodiment
As shown in Figure 1, the optical cable outward appearance is circular.5 is the suspension type optical cable core, its external form is ' 8 ' font that ' 8 ' font or electronic clock show, it is by polyvinylchloride or low smoke and zero halogen plastics LSZH sheath material optical fiber 4 and reinforcement 7 to be wrapped up an integral body that forms, optical fiber can be 1 core or 2 cores, and the reinforcement 7 of cable core can be steel wire or Fibreglass Reinforced Plastics FRP.Adopt the suspension type optical cable core can make things convenient for welding or with the construction that continues of quick connection assembly.
1 is oversheath, can be that black polyethylene PE or low smoke and zero halogen plastics LSZH constitute.
2 is glass fiber reinforced plastics FRP, it is distributed in the minor axis both sides of suspension type optical cable core 5 for NAG Fibreglass Reinforced Plastics, with suspension type optical cable core 5 just in time constitute one similarly circular, the mode by waterstop 3 is rolled into regular circular with loose suspension type optical cable core 5, Fibreglass Reinforced Plastics 2.Its main effect is the intensity that increases optical cable, makes optical cable keep certain degree of hardness, and makes optical cable keep good property at high and low temperature.In addition, can be stranded between glass fiber reinforced plastics 2 and the suspension type optical cable core 5 can be not stranded yet.
3 is waterstop, 6 pricks for having that yarn is tied up and setting is spun the synthetic fibre yarn or torn rope between waterstop 3 and oversheath 1, is convenient to construction and auxiliary the reinforcement.
