Abstract
The utility model belongs to the field of optical communication transmission carriers, and particularly relates to a novel fully dry indoor and outdoor FTTH (Fiber To The Home) leading in optical cable. The optical cable comprises an optical fiber, a water blocking yarn and water blocking powder from inside to outside and is wrapped by a loose tube, and Kevlar, a film-laminated double-side water blocking tape, a low-smoke zero-halogen flame-retardant inner sheath, another film-laminated double-side water blocking tape, an FRP (Fiber Reinforce Plastic) reinforcement part, a rip cord, a nylon sheath (11) and a PE outer sheath. The optical cable can be used indoors and outdoors without a joint, so as to reduce the transmission attenuation and maintenance cost. The tensile strength of the optical cable is ensured, and the hidden danger a metallic strengthened optical cable of leading lightening indoors is eliminated by virtue of the Kevlar and the FRP non-metallic reinforcement part. By virtue of the fully dry structural design free of ointment filling, environmental pollution caused by ointment is avoided.
Description
Technical field
The utility model belongs to optical communication and transmits carrier scope, the dual-purpose FTTH leading in cable of particularly a kind of dry type indoor and outdoor.
Background technology
For the cable of device usefulness such as some instruments, instrument, electronic equipment and robotization, require less bending radius and good flexibility during use, and dilatory frequent, require to have higher tensile strength and tensile strength.Anti-, tensile strength deficiency of common flexible cable often cause cable life shorter.
The utility model content
Along with the high speed development of modern optical telecommunications, Fiber to the home (FTTH) has been megatrend, and at present, traditional optical cable normally indoor and outdoor segmentation uses, and the middle joint that adopts connects, and during connection, generally needs specialized equipment and professional to operate.And tie point also needs special container to couple together.Increase maintenance cost.The quality of joint is also bigger to the influence of optical cable transmission performance.In order to increase the reliability of system, reduce the maintenance cost of system, press for develop can indoor again can be at the optical cable of outdoor application.Indoor optical cable needs good flame performance and bending property, and the outdoor use optical cable not only will have good block-water effect, also enough tensile strength will be arranged.Simultaneously, optical cable should avoid selecting for use ointment to fill, and to prevent optical cable in use, causes ointment water clock contaminated environment.The optical cable reinforcement should not use metal material simultaneously, to prevent that optical cable from drawing thunder and entering the room.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned technical deficiency, and provides a kind of novel dry type indoor and outdoor dual-purpose FTTH leading in cable.
The described dry type chamber dual-purpose FTTH leading in cable of inside/outside comprises and is coated on that the Kev that optical fiber, water blocking yarn, water-proofing powder and loose sleeve pipe in the loose sleeve pipe set gradually draws outward, the two-sided waterstop A of overlay film, low-smoke non-halogen flame-retardant inner sheath, the two-sided waterstop B of overlay film, FRP reinforcement, tears rope, nylon sheath wire, PE oversheath.Described optical fiber and the water blocking yarn Shu Hehou that walks abreast has water-proofing powder in its surface adhesion, coats loose sleeve pipe again outside it.
Described Kev draws and vertically is coated on uniformly outside the loose sleeve pipe, its outer two-sided waterstop A of overlapping coating overlay film.
The outer two-sided waterstop B of overlapping coating overlay film of described low-smoke non-halogen flame-retardant inner sheath, its outer nylon sheath wire that coats vertically evenly is provided with some FRP reinforcements and tears rope between nylon sheath wire and waterstop.
The beneficial effects of the utility model are: can be used for indoor and outdoor simultaneously, not need joint, reduce transmission attenuation and maintenance cost.The utility model adopts Kev to draw the non-metal reinforcement member with FRP, has guaranteed the tensile strength of optical cable, and that has eliminated simultaneously that metal strengthens optical cable draws the thunder hidden danger of entering the room, and has improved the bending property of optical cable in addition.Optical cable adopts the dry type structure, and factice for filling has not been eliminated the pollution of ointment to environment.
Description of drawings
Fig. 1 is the cross section structure synoptic diagram of the dual-purpose FTTH leading in cable of novel dry type indoor and outdoor.
Among the figure,
1 is optical fiber, and 2 is water blocking yarn, and 3 is water-proofing powder, and 4 is loose sleeve pipe, and 5 for Kev draws, and 6 is the two-sided waterstop A of overlay film, and 7 is the low-smoke non-halogen flame-retardant inner sheath, and 8 is the two-sided waterstop B of overlay film, and 9 is the FRP reinforcement, and 10 for tearing rope, and 11 is nylon sheath wire, and 12 is the PE oversheath.
Embodiment
The utility model provides a kind of novel dry type indoor and outdoor dual-purpose FTTH leading in cable.The outer water-proofing powder 3 that is stained with of optical fiber 1 and water blocking yarn 2 is restrainted and is closed as shown in Figure 1, extrude loose sleeve pipe 4 outside it, the outer Kev that vertically twines of pine sleeve pipe draws 5 enhancement Layers, its outer two-sided waterstop A6 of overlapping wrapped overlay film, its outer low-smoke non-halogen flame-retardant inner sheath 7 that extrudes, the outer two-sided waterstop B8 of overlapping wrapped overlay film of inner sheath, its outer nylon sheath wire 11 that extrudes, between nylon sheath wire 11 and the two-sided waterstop B8 of overlay film, be provided with some FRP reinforcements 9 and tear rope 10, outside nylon sheath wire, extrude PE oversheath 12.
The utility model adopts water blocking yarn and water-proofing powder to play fine block-water effect, has eliminated the pollution of the used greasy for preventing water of ordinary optical cable to environment, has enlarged the range of application of product.The utility model adopts Kev to draw the reinforcement the most with FPR, greatly improved the tensile strength of optical cable, and that has eliminated simultaneously that metal reinforcement might cause draws the thunder hidden danger of entering the room, and has improved the bending property of optical cable in addition.The two-sided waterstop B8 of removal the utility model overlay film, nylon sheath wire 11 and PE oversheath 12 promptly can be used for indoor, and be easy to operate without fibre-optical splice, guarantees properties of optical fiber cable simultaneously.
