Abstract
The utility model relates to a high strength waterproof optical cable which is suitable for optical cable communication with various erecting modes in a long distance trunk line and a local network. A cable core which comprises a plurality of bundles of communicating medium and is filled with waterproof petroleum jelly is provided with buffer material which has elasticity and waterproof property outside a secondary covering casing tube, the edge of a fan-shaped metal section is filled with waterproof petroleum jelly, and the fan-shaped metal section is coated by a sealed circular casing through a metal-polyethylene composite metal tape, which forms the high strength waterproof optical cable. The performance of moisture resistance, water resistance, lateral pressure resistance and impact force resistance for the optical cable can be improved.
Description
The utility model is about communication cable.
Be used for long-distance or the communication of office level network cable, usually optical cable is embedded in underground, set up aerial or be layered on and wait multiple mode to use under water.Therefore require optical cable itself should have multinomial performances such as good protection against the tide, waterproof, tension, lateral pressure resistant and temperature coefficient.Domestic general cable configuration pattern has layer strand optical cable at present, as GYTA series; The skeleton optical cable is as GYGTV series.The shield system of these two kinds of structures adopts waterproof petroleum jelly and aluminum-polyethylene material in order to moistureproof, waterproof, and its lateral pressure resistant and tensile property are not good.Behind the armouring embossing steel band, the optical cable bending property is relatively poor again." super strong type beam tube type cable " its shield system increased trapezoidal wire and overarched after stranded nearest domestic the appearance, improved optical cable lateral pressure resistant and resistance to tension.But humidity resistance is relatively poor, and the temperature adaptation scope is lower, and it is also not ideal to resist repeatedly impact capacity.For example under certain pressure or impulsive force, trapezoidal wire radially is subjected to displacement along xsect, causes secondary impaired to be directed at optical fiber by multiple casing deformation or damage.When if ambient temperature changes greatly (as the temperature variation at northern China daytime and night), optical fiber secondary is differed bigger by the thermal expansivity of multiple sleeve pipe and trapezoidal wire, between is formed the space, after catching a cold, moisture in the space condenses into the globule, attached to optical fiber secondary by on multiple sleeve pipe and the every trapezoidal wire, the existence of water or aqueous vapor, corrosion trapezoidal wire, infringement cable machinery performance.Moreover the expansion coefficient of water is far above the expansion coefficient of the multiple sleeve pipe of secondary quilt, to making secondary by of the bigger strain of influence generation of multiple sleeve pipe owing to aqueous vapor, thereby be directed at optic fibre force and exceed the scope that optical fiber allows strain, cause little curved loss to increase even obstructed light." animal-resistant cable " of the U.S., shield system all adopts insulating material, and in the arc piece, add fibrous matter, prevent that rodent from repeating to injure cable, the wherein spiral arc piece structure that is twisted into housing, same opposing impact capacity is relatively poor, the employing ligule that interconnects at edge or groove shape profile vertically, improve and stop water to immerse inner ability along the adjacent tiles edge, perhaps also increase some impact resistances, but the technology of this structure is complicated, has improved the optical cable cost.
The purpose of this utility model is that anti-sealing enters along the radial and axial of optical cable, fully guarantees the stranded back of scallop wire composition tubular shell, protection optical cable, improves optical cable lateral pressure resistant and impact resistance.
Ruggedized fiber optic cable is that optical fiber, waterproof petroleum jelly, the multiple sleeve pipe of secondary quilt, fan-shaped metal splits, water barrier and oversheath are formed, and the material of water barrier comprises nonwoven fabrics.When it is characterized in that scallop wire is twisted into housing, fill the waterproof petroleum jelly, promptly the fan-shaped metal splits that presents of its longitudinal axis transverse section is by waterproof petroleum jelly parcel, each edge and meet the crack to be filled by the waterproof petroleum jelly mutually; Outside fan-shaped metal splits housing, indulge the protective jacket that bag one deck matter is hard and have certain intensity tightly.The material of this protective jacket comprises the composite band of metal tape single or double coated polyethylene film, takes a mouthful place at metal compound belt and adopts welding process, makes it form closed protective jacket.Protective jacket helps stranded scallop wire to form the garden housing on technology.
The utlity model has following advantage: set up water barrier by multiple sleeve pipe periphery at secondary, when this material runs into moisture or water, material itself expands, be full of secondary by the slit between multiple sleeve pipe and the fan-shaped metal splits, stop moisture or water to enter, this waterproof material has elasticity simultaneously, before stressed its power of generation strain of fan-shaped metal splits is delivered to the multiple sleeve pipe of secondary quilt, can play buffer action, reduce optic fibre force intensity.When stranded scallop wire, the waterproof petroleum jelly is filled at its edge, and another has increased performance moistureproof, waterproof.The vertical outward bag protective jacket of fan-shaped metal splits housing after stranded, not only increased the water resistance of optical cable once more, stoped simultaneously between the fan-shaped metal splits because of being subjected to local assault power (for example strike of shotgun), fan-shaped metal splits is along the radially issuable relative displacement of its xsect.Improve optical cable protection against the tide, waterproof, lateral pressure resistant, tension, shock proof ability in a word, enlarged the optical cable range of application.
