Abstract
The utility model relates to a full-medium double-protection-layer semi-dry type center beam pipe ribbon-shape optical cable, which comprises a loose sleeve pipe, wherein optical fiber ribbons are paved in the loose sleeve pipe, a water-resistant ribbon is covered outside the loose sleeve pipe, a tearing rope is added outside the water-resistant ribbon, an inner protection layer is covered outside the tearing rope, a tearing rope is also added outside the inner protection layer, and in addition, glass fiber and an outer protection layer are covered outside the inner protection layer. The full-medium double-protection-layer semi-dry type center beam pipe ribbon-shaped optical cable is characterized in that the optical cable adopts full-medium materials and does not adopt any metal material. Ointment is filled in the loose sleeve pipe, the water-resistant ribbon is covered outside the loose sleeve pipe for realizing water resistance, and a semi-dry type structure is realized. The optical cable has the beneficial effects that 1. compared with the existing center beam pipe type structure, the optical cable has the advantages that: 1. the materials are full-medium materials, and thunder and lightning prevention effects can be realized; 2. the glass fiber is adopted to be used as reinforcing elements, the glass fiber is soft and is convenient to bend, and the mouse biting can be prevented; 3. the water-resistant ribbon is adopted to be covered outside the loose sleeve pipe, in addition, the tearing ropes are added, and the optical cable is convenient to peel during construction; and 4. double protection layers are adopted, and the protection effect is good.
Description
Technical field
The utility model belongs to the optical cable with high density of optic fibre.Be particularly related to the two sheath half dry type centers of a kind of full medium beam tube ribbon optical cable.
Background technology
Along with the fast development of the communication technology, the central beam tube type optical cable is widely used in the fiber cable network.Existing central beam tube type optical cable, fibre ribbon is sleeved in the loose sleeve pipe, factice for filling and coat the embossing steel band outside loose sleeve pipe, the steel band both sides are strengthened with parallel steel wire, coat oversheath again and constitute, adopt this structure when construction, owing to the reason of parallel steel wire and steel band, optical cable is difficult for out stripping, is not suitable for many thunders and lightnings and rattish occasion.
The utility model content
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and the center beam tube ribbon optical cable of the full medium pair sheath half dry types that a kind of structure was provided with rationally, was applicable to special occasions is provided.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
The two sheath half dry type centers of a kind of full medium beam tube ribbon optical cable, it is characterized in that: a loose sleeve pipe is arranged, be laid with fibre ribbon in the pine sleeve pipe, the pine sleeve pipe coats waterstop outward, waterstop is added with outward tears rope, waterstop and its outer tearing coat sheath outside the rope, sheath is added with again outward and tears rope, and bag sheath and its outer tearing coat glass fibre and outer jacket outside the rope.
Press such scheme, described optical cable adopts nonmetal full dielectric material, does not use any metal material.
Press such scheme, described glass fibre is as reinforcement, and softness is convenient to bending, but and mouse bite preventing.
Press such scheme, factice for filling in the described loose sleeve pipe, loose sleeve pipe coats waterstop outward and blocks water, and is the half dry type structure.
Press such scheme, the diameter of described loose sleeve pipe is 6.0～6.7mm, and loose sleeve pipe includes the fibre ribbon of 1～6 12 core.
Press such scheme, described loose sleeve pipe adopts waterstop to coat outward, and adds and tear rope, stripping fiber optic cables when being convenient to construct.
Press such scheme, described optical cable adopts two sheath protections, and sheath thickness is 1.0mm, and outer jacket thickness is 1.8～2.0mm.
The beneficial effects of the utility model are: 1, compare with existing central beam tube type structure, material therefor is full dielectric material, can prevent thunder and lightning; 2, adopt glass fibre as reinforcement, softness is convenient to bending, but and mouse bite preventing; 3, loose sleeve pipe adopts waterstop to coat outward, and adds and tear rope, stripping fiber optic cables when being convenient to construct; 4, adopt two sheaths, protectiveness is good.
Description of drawings
Fig. 1 is the radial structure sectional view of an embodiment of the utility model.
Among the figure: 1 fine cream, 2 fibre ribbons, 3 loose sleeve pipes, 4 tear rope, 5 waterstops, 6 sheaths, 7 glass fibre, 8 outer jackets
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
The two sheath half dry type centers of a kind of full medium beam tube ribbon optical cable, a loose sleeve pipe is arranged, be laid with fibre ribbon in the pine sleeve pipe, the pine sleeve pipe coats waterstop outward, waterstop is added with outward tears rope, waterstop and its outer tearing coat sheath outside the rope, sheath is added with again outward and tears rope, and bag sheath and its outer tearing coat glass fibre and outer jacket outside the rope.Optical cable adopts nonmetal full dielectric material, does not use any metal material.Glass fibre is as reinforcement, and softness is convenient to bending, but and mouse bite preventing.Factice for filling in the pine sleeve pipe, loose sleeve pipe coats waterstop outward and blocks water, and is the half dry type structure.The pine sleeve pipe adopts waterstop to coat outward, and adds and tear rope, stripping fiber optic cables when being convenient to construct.
Concrete materials used explanation: loose sleeve pipe 3 is the loose sleeve pipe of polybutylene terephthalate (PBT), be laid with fibre ribbon 2 in the pine sleeve pipe, and the fine cream 1 of filling, the diameter of pine sleeve pipe can be 6.0～6.7mm, 1～6 of interior dress fibre ribbon, the outsourcing of pine sleeve pipe is around waterstop 5, waterstop adds tears rope 4, and coat inner sheath 6, and inner sheath is tygon (PE) sheath, sheath adds tears rope 4, and coating glass fibre 7, glass fibre coats outer jacket 8 outward, outer jacket available polyethylene (PE), bittern-free flame-proof material or nylon material are made, and constitute the two sheath half dry type central beam pipe optical cables of the rounded full medium of radial section.Sheath thickness is 1.0mm, and outer jacket thickness is 1.8～2.0mm.
