Abstract
A kind of central beam tube type non-metallic optical fiber cables is made of optical fiber or fibre ribbon, fine cream, loose sleeve pipe, reinforcement and sheath.The pine sleeve pipe is arranged on the periphery of optical fiber or fibre ribbon and fine cream, fine cream be arranged on optical fiber or fibre ribbon around, reinforcement is arranged on the periphery of loose sleeve pipe, sheath is arranged on the periphery of reinforcement.Reinforcement is nonmetal reinforced pipe, is made of glass fibre, tackifier and hot melt adhesive, utilizes tackifier and hot melt adhesive to become pipe glass fibre is bonding.The tubulose reinforcement forms by squeezing the glass fibre reinforced pipe or indulging bag glass fibre reinforcing band, and the tubulose reinforcement plays a part to strengthen and lateral pressure resistant.This optical cable is nonmetal optical cable, and structure is a central beam tube type; Cost has reduced by 30～40% when counting with core; There is not iron oxidation liberation of hydrogen problem in no ferrous material; Avoided the possibility of being struck by lightning, also can use in the place of strong-electromagnetic field; Weight saving 50～60%, cross-sectional area reduce nearly 70%; Need not to add other material water-proof material, block-water performance is good.
Description
Technical field
The utility model relates to physical field, relates in particular to optical element, particularly non-metallic optical fiber cables, and concrete is a kind of central beam tube type non-metallic optical fiber cables.
Background technology
In the prior art, the central beam tube type optical cable is made of optical fiber, fine cream, loose sleeve pipe, reinforcement, composite steel-plastic belt, waterstop or water blocking yarn, phosphatization steel wire and sheath.The pine sleeve pipe is arranged on the periphery of optical fiber and fine cream, fine cream be arranged on optical fiber around, sheath is arranged on the most peripheral of optical cable, the vertical Baogang of periphery plastic composite strip at loose sleeve pipe, place water blocking yarn or waterstop, stranded again one deck phosphatization steel wire, perhaps symmetrical parallel is placed two phosphatization steel wires in sheath.The cable jacket of this structure is thick, Heavy Weight, and cross-sectional area is big.Simultaneously,, can't use, and iron there is the possibility of oxidation liberation of hydrogen, causes the hydrogen loss of optical fiber in the place that has strong-electromagnetic field because it contains ferrous material.So, a lot of countries non-metallic optical fiber cables that adopt more.Non-metallic optical fiber cables is made of optical fiber, reinforcement and sheath, and its structure adopts layer-twisted type or skeleton usually, but the optical cable of these two kinds of structures need consume more material, and is when counting with core, higher by 30%～40% than central beam tube type optical cable cost.
Summary of the invention
The purpose of this utility model provides a kind of central beam tube type non-metallic optical fiber cables, described this central beam tube type non-metallic optical fiber cables will solve that central beam tube type cable jacket of the prior art is thick, Heavy Weight, cross-sectional area is big and include ferrous material, can't use in the place that has strong-electromagnetic field, and may cause technical matters the hydrogen loss of optical fiber.
The utility model is that the technical scheme that solution above-mentioned technical matters of the prior art is adopted provides a kind of central beam tube type non-metallic optical fiber cables, described this central beam tube type non-metallic optical fiber cables is by optical fiber or fibre ribbon, fine cream, the pine sleeve pipe, reinforcement and sheath constitute, described loose sleeve pipe is arranged on the periphery of described optical fiber or fibre ribbon and fine cream, wherein, described fine cream is arranged on the periphery of described optical fiber or fibre ribbon, described reinforcement is arranged on the periphery of described loose sleeve pipe, described sheath is arranged on the periphery of described reinforcement, it is characterized in that: the reinforcement that is provided with between described sheath and loose sleeve pipe is the tubulose reinforcement, and described loose sleeve pipe is arranged in the tube chamber of described tubulose reinforcement.
Further, described optical fiber is single-mode fiber or multimode optical fiber or fibre ribbon.
Further, described tubulose reinforcement is made of glass fibre, tackifier and hot melt adhesive.
Further, described tubulose reinforcement is made of glass fibre reinforced pipe of extruding or vertical bag glass fibre reinforcing band.Preferred scheme is vertical bag glass fibre reinforcing band, and the heat of sheath makes the bonding one-tenth pipe of glass fibre reinforcing band when utilizing squeeze jacket.
Further, described vertical bag glass fibre reinforcing band is made of glass fibre, tackifier and hot melt adhesive.
Further, described glass fibre and tackifier be bonding become a shoestring, described hot melt adhesive evenly be arranged on described shoestring around.
Further, the quantity of described glass fibre is more than two, the axially parallel that direction and optical cable are set of described glass fibre.
Further, total cross-sectional area of described glass fibre accounts for 80%～97% of described tubulose reinforcement cross-sectional area.
Further, described sheath is made of high density polyethylene or medium density polyethylene or low density polyethylene or polyvinyl chloride material.
Further, described sheath is made of the low smoke and zero halogen material.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model has coated a nonmetal reinforced pipe outside the loose sleeve pipe of optical fiber, play a part to strengthen and lateral pressure resistant; Its structure is a central beam tube type, compares with the non-metallic optical fiber cables of prior art, and when counting with core, its cost has reduced by 30%～40%, compares with the central beam tube type optical cable of prior art, and its cost has reduced by 5%～10%; In optical cable of the present utility model, do not have ferrous materials such as steel wire, steel band, do not have the problem of iron oxidation liberation of hydrogen; Use in the area of rainy many thunders, avoided possibility of being struck by lightning, also can use in the place that has strong-electromagnetic field: the cryogenic property of optical cable is good, the low temperature contraction can not occur; Physical dimension of the present utility model is little, in light weight, compares with the non-metallic optical fiber cables of prior art, and its cross-sectional area reduces nearly 70%, weight saving nearly 50%, compare with the central beam tube type optical cable of prior art, it is nearly 70% that its cross-sectional area reduces, weight saving nearly 60%; And need not to add other material water-proof material, optical cable water-blocking is functional.
