Description

A kind of ruggedized fiber optic cable

Technical field

The utility model belongs to optical cable technology field, particularly a kind of ruggedized fiber optic cable.

Background technology

Along with fiber-to-the-home fast development in the development of optical communication and 3G and 4G network system, the usable range of communications optical cable has obtained expansion widely.But in laying communications optical cable process, optical cable usually will stretch, is wound around, crooked or extruding, thereby cause the damage of optical fiber to affect the transmission performance of optical cable, the tensile strength of optical cable, compressive strength are had higher requirement.Therefore need to design a kind of tension and compressive strength is high, be applicable to the optical cable that lays and use under complex environment.

Utility model content

The purpose of this utility model for solve described in background technology, design a kind of tension and compressive strength high, the problem of the optical cable that is applicable to lay under complex environment and uses, a kind of ruggedized fiber optic cable is provided, it is characterized in that, optical fiber 1 is directly placed in loose sleeve pipe 3, between pine sleeve pipe 3 and optical fiber 1, fill fine cream 2, armor 4 is coated on loose sleeve pipe 3 and forms fiber unit 5; Strengthening core 13You center, center sheath 14 is coated, to be coated centered by sheath 14 center, center strengthening core 13,2～24 fiber units 5 and gasket for packing 6 are stranded, when stranded, fill block water silk 8 and factice for filling 7, wrapped water blocking tape layer 9 forms the high-strength light cable core of circular cross section again, the outer wrapped water blocking yarn 10 of water blocking tape layer 9, the outer vertical alclad plastic composite strip 11 of water blocking yarn 10.By polyolefin jacket layer 12 metallized aluminum plastic composite strip 11, form ruggedized fiber optic cable again;

Described armor 4 adopts interlocking armouring, and armoring material is steel band;

Described center strengthening core 13 is the many stranded wire rope that form of thin galvanized steel steel wire;

The material of described center sheath 14 is nylon.

The outer interlocking armor that adopts of fiber unit 5 of the present utility model, fiber unit 5 and gasket for packing 6 carry out stranded, and there is metal strengthening core at center, has improved tension and the compressive strength of optical cable; Fiber unit 5 and gasket for packing 6 carry out usining stranded time blocking water silk 8 and factice for filling 7 filled as filling material, more wrapped water blocking tape layer 9 and water blocking yarn 10 successively, after water blocking tape layer 9 and water blocking yarn 10 are met water, can expand rapidly, improved the block-water performance of optical cable; Be applicable to laying and using under complex environment.

The beneficial effects of the utility model are, the loose sleeve pipe of fiber unit adopts sheathed structure outward, makes each fiber unit have protection, and there is the center strengthening core of metal at optical cable center, has improved tension and the compressive strength of optical cable; Filling material in Cable Core adopts block water silk and factice for filling to fill, Cable Core adopt outward waterstop and water blocking yarn wrapped, improved the block-water performance of optical cable.

In figure, 1--optical fiber, the fine cream of 2--, 3--pine sleeve pipe, 4--armor, 5--fiber unit, 6--gasket for packing, 7--factice for filling, the 8--silk that blocks water, 9--water blocking tape layer, 10--water blocking yarn, 11--aluminium-plastic tape, 12--polyolefin jacket layer, center strengthening core 13, center sheath 14.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is further illustrated.

The utility model embodiment is a kind of ruggedized fiber optic cable, the cross-sectional structure schematic diagram that accompanying drawing 1 is ruggedized fiber optic cable.Optical fiber 1 is directly placed in loose sleeve pipe 3, fills fine cream 2 between loose sleeve pipe 3 and optical fiber 1, and armor 4 employing interlocking armourings are coated on loose sleeve pipe 3 and form fiber unit 5, and armoring material is steel band, as shown in Figure 2.Strengthening core 13You center, center sheath 14 is coated, and center strengthening core 13 adopts the many stranded wire rope that form of thin galvanized steel steel wire, and the material of center sheath 14 is nylon.To be coated centered by sheath 14 center, center strengthening core 13,24 fiber units 5 and gasket for packing 6 are stranded, fill block water silk 8 and factice for filling 7, more wrapped water blocking tape layer 9 form the high-strength light cable core of circular cross sections when stranded.The outer wrapped water blocking yarn 10 of water blocking tape layer 9, the outer vertical alclad plastic composite strip 11 of water blocking yarn 10, then form ruggedized fiber optic cable by polyolefin jacket layer 12 metallized aluminum plastic composite strip 11.

In the utility model, at the armor 4 of loose sleeve pipe 3 outer cladding one deck interlock type armourings, there is the nylon of employing at the center of optical cable as sheath 14 center, center strengthening core 13, effectively improves tension and the compressive strength of optical cable; Employing blocks water silk 8 and factice for filling 7 as filling material, after the wrapped high-strength light cable core that forms circular cross section of water blocking tape layer 9, at the wrapped water blocking yarn 10 of water blocking tape layer 9, reduces the gap between aluminium-plastic tape 11 and Cable Core.After water blocking tape layer 9 and water blocking yarn 10 water suctions, expand rapidly, stop the expansion of moisture, improved the block-water performance of optical cable; The utility model is applicable to laying and using under complex environment.
