Abstract
The utility model announces the dual-purpose optical cable of a kind of light-duty dry type indoor and outdoor, belongs to optical cable technology field.Optical fiber and water blocking yarn carry out bundle and close, and after the surface adhesion water-proofing powder of optical fiber and water blocking yarn, directly be placed on composition fiber unit in Loose tube, the reinforcement that blocks water is filled around the Loose tube of 1 ~ 24 fiber unit, and stranded rear wrapped water blocking tape layer forms the cable core of circular cross section, block water reinforcement by water blocking yarn with aramid fiber is stranded forms, extrudes the inner restrictive coating of low-smoke non-halogen flame-retardant outside cable core, after inner restrictive coating outer surface damping oil, extrude PE external sheath layer.The utility model adopts water blocking yarn, water-proofing powder, waterstop all to serve block-water effect from horizontal and vertical; Adopt by the stranded reinforcement that blocks water of water blocking yarn and aramid fiber, ensure that the tensile strength of optical cable, the thunder that draws simultaneously eliminating metal reinforcement is entered the room hidden danger, enhances the effect that transverse direction blocks water, also improves the bending property of optical cable.The utility model can use at indoor or outdoors environment.
Description
Technical field
The utility model belongs to optical cable technology field, particularly the dual-purpose optical cable of one light-duty dry type indoor and outdoor.
Background technology
Along with the high speed development of Modern optical communication cause, the paces of 4G base station construction are accelerated, and increasingly increase the demand of indoor and outdoor optical cable, require less bending radius and good flexibility when optical cable uses, and dilatory frequent, require higher tensile strength and tensile strength.Anti-tensile, the tensile strength of ordinary optical cable are not enough, often cause cable lifetime shorter.
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 larger on the impact of optical cable transmission performance.Indoor optical cable needs good fire resistance and bending property, and outdoor use optical cable not only will have good block-water effect, also will have enough tensile strength.Meanwhile, optical cable should be avoided selecting ointment to fill, and to prevent optical cable in use, causes ointment water clock contaminated environment.Optical cable reinforcement should not use metal material simultaneously, draws thunder enter the room to prevent optical cable.In order to increase the reliability of system, reduce the maintenance cost of system, can again can at the optical cable of outdoor application in indoor in the urgent need to developing.
Utility model content
The purpose of this utility model is to solve the problem described in background technology, and provide the dual-purpose optical cable of a kind of light-duty dry type indoor and outdoor, it is characterized in that, optical fiber 1 and water blocking yarn 2 carry out bundle and close, and after optical fiber 1 with the surface adhesion water-proofing powder 3 of water blocking yarn 2, directly be placed on composition fiber unit in Loose tube 4, the reinforcement 5 that blocks water is filled around the Loose tube of 1 ~ 24 fiber unit, and stranded rear wrapped water blocking tape layer 6 forms the cable core of circular cross section, extrude inner restrictive coating 7 outside cable core, after inner restrictive coating 7 outer surface damping oil, extrude external sheath layer 8;
The described reinforcement 5 that blocks water is by water blocking yarn and aramid fiber is stranded forms;
The material of described inner restrictive coating 7 is low smoke halogen-free flame-retardant polyolefin;
The material of external sheath layer 8 is PE (tygon);
The beneficial effects of the utility model are, adopt by water blocking yarn and the stranded reinforcement that blocks water of aramid fiber, ensure that the tensile strength of optical cable, the thunder that draws simultaneously eliminating metal reinforcement is entered the room hidden danger, enhance the effect laterally blocked water, also improve the bending property of optical cable.Optical cable adopts dry type structure, and not factice for filling, eliminates the pollution of ointment to environment.The utility model can be used for indoor and outdoor, does not need joint, reduces transmission attenuation and maintenance cost.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of the dual-purpose optical cable of light-duty dry type indoor and outdoor.
In figure, 1 is optical fiber, and 2 is water blocking yarn, and 3 is water-proofing powder, and 4 is Loose tube, and 5 is the reinforcement that blocks water, and 6 is water blocking tape layer, and 7 is inner restrictive coating, and 8 is external sheath layer.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further illustrated.The present embodiment is the dual-purpose optical cable of a kind of light-duty dry type indoor and outdoor.Fig. 1 is the cross-sectional structure schematic diagram of the dual-purpose optical cable of light-duty dry type indoor and outdoor.
Optical fiber 1 and water blocking yarn 2 carry out bundle and close, and after optical fiber 1 with the surface adhesion water-proofing powder 3 of water blocking yarn 2, directly be placed on composition fiber unit in Loose tube 4, the reinforcement 5 that blocks water is filled around the Loose tube of 6 fiber units, and stranded rear wrapped water blocking tape layer 6 forms the cable core of circular cross section, extrude inner restrictive coating 7 outside cable core, after inner restrictive coating 7 outer surface damping oil, extrude external sheath layer 8.Block water reinforcement 5 by water blocking yarn and aramid fiber is stranded forms, and the material of inner restrictive coating 7 is the polyolefin of low-smoke non-halogen flame-retardant, and the material of external sheath layer 8 is PE material.
The utility model adopts water blocking yarn, water-proofing powder, waterstop all to serve block-water effect from horizontal and vertical, eliminates ordinary optical cable greasy for preventing water used to the pollution of environment, expands the range of application of product.The utility model adopts aramid fiber and the stranded conduct of water blocking yarn to block water reinforcement, ensure that the tensile strength of optical cable, and the thunder that draws simultaneously eliminating metal reinforcement is entered the room hidden danger, enhances the effect laterally blocked water, also improves the bending property of optical cable.Damping oil of the present utility model make peel separation PE oversheath and inner sheath easy to operate, PE external sheath layer remove after, namely can be used for indoor, without fibre-optical splice, ensure properties of optical fiber cable simultaneously.Be applicable to indoor or outdoors environment use.
