Abstract
The utility model discloses a small-outer-diameter high-strength bending-resistant indoor single-core cable, the section structure of which sequentially comprises a high-strength bending-resistant optical fiber, an optical fiber packed protective layer (5), a tensile reinforcing wire layer (6) and an outer sheath (7) from the core part to the outside. As for the utility model, the cable is made by adopting the novel high-strength bending-resistant optical fiber. A layer of high-strength high-tightness polymeride coating is additionally arranged between a fiber core packed layer and a resin coating of the original optical fiber, so that the fibre cable has the characteristics of high strength, bending resistance, humidity resistance, heat resistance and the like. Therefore, the cable adopting the structure can be bent in heavy curvature, and the applicability is greatly improved.
Description
Technical field
The utility model relates to optic fibre wire, relates in particular to a kind of crooked single fiber cable of high strength anti that is used as the used inside cable of comprehensive wiring and communication facilities interconnection line, fiber-to-the-home (FTTH) internal home network system, intra-office high speed fibre networking distribution, the vertical cloth cable in optical fiber wideband building, horizontal cloth cable, the wiring of FTTX skin cable etc.
Background technology
Traditional optical cable is to be formed by the optical fiber of heart portion and an outsourcing number layer protective seam, and the cross-section structure of traditional optical fiber is made up of the glass core of core and the glass coating, enhancement Layer and the outer skin protective layer that are wrapped in glass core periphery successively.This constructed products has obtained using widely, and still, along with popularizing of fiber-to-the-home (FTTH), people have had higher requirement to the performance of optical cable.Since conventional cable can not deep camber bending, moisture-proof and temperature tolerance relatively poor, adaptability is not enough.Industry this technical matters that needs to be resolved hurrily proposes the optical cable of a kind of high strength, anti-bending, moisture-proof and heatproof.
Summary of the invention
The utility model is to solve the existing optical cable relatively poor technical matters of winding, moisture-proof and temperature tolerance of can not curling, and proposes a kind of indoor little external diameter high strength anti bending single fiber cable that can guarantee communication quality.
For solveing the technical problem, the crooked single fiber cable of the indoor little external diameter high strength anti that the utility model proposes, its cross-section structure outwards is followed successively by the resistant to bending optical fiber of high strength, optical fiber hard-pressed bale protective seam, tension line feeder layer and oversheath by core.
Wherein, the cross-section structure of described optical fiber outwards is followed successively by glass fibers nuclear, fine nuclear covering, polymer coating and resinous coat by core.
The diameter of described fine nuclear is that 9 microns～50 microns, the diameter of fine nuclear covering are that 100 microns～150 microns, the diameter of polymer coating are that 150 microns～200 microns, resin-coated diameter are 225 microns～275 microns.
The diameter of described optical fiber hard-pressed bale protective seam is that 0.5 millimeter, oversheath diameter are 1.4 millimeters.
The utility model adopts a kind of high strength, resistant to bending novel optical fiber to make optical cable.This optical fiber is examined at the fibre of original optical fiber and is added one deck high strength and bubble-tight polymer coating between covering and the resinous coat, makes optic fibre wire have characteristics such as high strength, anti-bending, moisture-proof and heatproof.So adopt the bending that the optical fiber of this structure can deep camber, applicability improves greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
Fig. 1 is a cut-open view of the present utility model;
Fig. 2 is the cut-open view of the utility model heart portion optical fiber.
Embodiment
As shown in Figure 1 and Figure 2, the crooked single fiber cable of described indoor little external diameter high strength anti, its cross-section structure outwards is followed successively by the resistant to bending optical fiber 8 of high strength, optical fiber hard-pressed bale protective seam 5, tension line feeder layer 6 and oversheath 7 by core.Wherein the cross-section structure of optical fiber 8 outwards is followed successively by glass fibers nuclear 1, fine nuclear covering 2, polymer coating 3 and resinous coat 4 by core.It is that 100 microns～150 microns, the diameter of polymer coating 3 are that 150 microns～200 microns, the diameter of resinous coat 4 are 225 microns～275 microns that the diameter of the fine nuclear 1 of the utility model is generally 9 microns～50 microns, the diameter of fine nuclear covering 2.In the present embodiment, the diameter of fine nuclear 1 is that 9 microns, the diameter of fine nuclear covering 2 are that 125 microns, the diameter of polymer coating 3 are that 140 microns, the diameter of resinous coat 4 are 250 microns.The diameter of Polyvinylchloride optical fiber hard-pressed bale protective seam 5 is that 0.5 millimeter, plastic cement oversheath 7 diameters are 1.4 millimeters.The tension line feeder can be the aramid fiber tow.
By experiment, promptly earlier optical fiber of the present utility model is folded at a distance of 3.5mm, and places between the two clamping plates.In the hot water of 90 ℃ of the two plates immersions that clips optical fiber, use the fine rupture time of acoustic monitoring instrument photometry more then.Conventional fiber then ruptured within 5 minutes, and the utility model optical fiber out-of-service time is stronger 100 times than ordinary optic fibre, and promptly the tired parameter of the utility model optical fiber is increased to n＞30 from n＞18 of conventional fiber, can effectively control maintenance cost.Checking test high strength anti curved fiber＞230kpsi (general optical fiber＞100kpsi).In light weight, anti-curved, withstand voltage, be fit to harsh environment and use down.The polymer coating good waterproof can be without petroleum jelly and Polyvinylchloride optical fiber hard-pressed bale protective seam, and is simple in structure, volume is little, construct simple and easy fast, can effectively reduce the optical cable installation cost.Polymer coating can divest easily with traditional wire-stripping pliers or hot soarfing device.Can be with conventional heat sealing machine with the utility model optical fiber and ordinary optic fibre welding.
