Description
Technical field
The utility model relates to a kind of miniature self-bearing type twin fiber cable.
Background technology
Existing self-support cable comprises the optical fiber 1 and the sheath 4 of extrusion molding in optical fiber 1 periphery that are positioned at optical cable center, be provided with the reinforcement 2 being positioned at optical fiber 1 both sides in sheath 4, reinforcement 2 and messenger wire 3 extrude mode parallel through suspender belt 5 and extrude sheath 4 and form butterfly cable (see Fig. 1).Optical fiber has single core to four-core, and existing self-support cable exists following shortcoming:
1. optical fiber and sheath close contact, the contraction due to material can affect the performance of optical fiber;
2. the material of the protective layer of outer fiber adopts PVC usually, easily soaks, and optical fiber can produce hydrogen loss;
3. optical cable needs when indoor use to remove messenger section, and the torsion of cable portion in short transverse, can not can only be rotated arbitrarily.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and provides a kind of miniature self-bearing type twin fiber cable, its compact conformation, and can improve the protection to optical fiber in optical cable construction widely.
The purpose of this utility model is achieved in that a kind of miniature self-bearing type twin fiber cable, comprises messenger section and cable portion, described messenger section be connected by suspender belt between cable portion and form the figure of eight, wherein,
Described messenger section comprises messenger wire oversheath and is positioned at the core bundle at messenger wire oversheath center, and core bundle forms by many zinc-coated wires are stranded;
The tensile elements that described cable portion comprises cable outer sheath, two optical fiber in cable outer sheath inner chamber and is filled between optical fiber and the internal chamber wall of cable outer sheath; Every root optical fiber comprises fiber optic protection layer and some optical fiber bodies hugged by fiber optic protection layer respectively; Described tensile elements adopts aramid yarn;
The material of described messenger wire oversheath, suspender belt and cable outer sheath adopts high flame resistance, low smoke halogen-free material and one extrusion moulding.
Above-mentioned miniature self-bearing type twin fiber cable, wherein, the material of described fiber optic protection layer is common low smoke and zero halogen material.
The technical scheme of miniature self-bearing type twin fiber cable of the present utility model, messenger section adopts galvanized strand wires, not only meet the requirement of optical cable tensile strength in built on stilts or vertical wirings use, also make whole optical cable more soft, and make jacket material and steel strand wires have larger adhesion; Cable portion adopts the protective layer hard-pressed bale of common LSZH material, both protected against the effects of immersions, and ordinary connector can be used again to connect; Whole optical cable adopts high flame retardant LSZH material as oversheath, makes optical cable meet the flame-retardancy requirements in indoor use procedure; The tensile elements of cable portion adopts aramid fiber, and after removing messenger section, optical cable still can meet the requirement of strength of indoor cable; In addition, the messenger section of optical cable and cable portion are without the need to using specific purpose tool and separable, easy to use; Optical fiber body in optical cable can use various types of optical fiber, meets the demand of different use occasion with this.Miniature self-bearing type twin fiber cable of the present utility model had both been applicable to indoor and outdoor in the networks such as fiber to the home and had used, and also can be used for vertical wirings and used.
Accompanying drawing explanation
Fig. 1 is the sectional view of the self-support cable of prior art;
