Description
Technical Field
The utility model relates to an optical cable especially relates to an anti side pressure stainless steel armor optical cable of high strength tensile.
Background
The existing commonly used structural optical cables mainly have three types: the optical cable comprises a layer stranded structure optical cable, a beam tube structure optical cable and a framework structure optical cable.
1. Layer stranded structure optical cable: the layer-stranded structure optical cable is formed by stranding 4 or more secondary coated optical fiber loose tubes (or partial filling ropes) around a central metal reinforcement into a round cable core, longitudinally wrapping a composite aluminum tape outside the cable core, extruding a polyethylene inner sheath, longitudinally wrapping a water-blocking tape and a double-sided coated corrugated steel (aluminum) tape, and finally wrapping a polyethylene outer sheath. If the number of cores is large or the requirement on the tensile resistance is high, a steel wire armor layer is added on the inner side of the outer sheath layer.
2. Bundle tube structure optical cable: the optical cable with the bundle tube structure is characterized in that optical fibers are sleeved in a spiral space loose sleeve made of high-modulus plastics, optical fiber ointment is filled in the sleeve to serve as a waterproof compound, a layer of non-woven fabric wrapped waterproof material and a steel wire armor layer (or two parallel steel wires are arranged on two sides) are applied to the outer portion of the sleeve, and a polyethylene sheath is extruded to form the cable.
3. Skeleton structure optical cable: the skeleton-type structural optical cable is formed by placing tightly sleeved optical fibers or primary coated optical fibers into spiral plastic skeleton grooves around a reinforced core. The skeleton-type optical cable has three types, namely a central additional spiral type, a positive and negative spiral type and a dispersion enhancement basic unit type.
The optical cable has the following defects:
1. the optical cable with layer-stranded structure contains a large number of optical fibers, the surplus length of the optical fibers in the optical cable is easy to control, the mechanical and environmental performance of the optical cable is good, and the optical cable is suitable for direct burial and pipeline laying and also can be used for overhead laying. But the structure is complex, the production is complex, the material consumption is high, and the tensile and lateral pressure resistance is insufficient. The layer-stranded structure optical cable has multiple layers of protective materials and contents, the characteristics of large volume and large weight are determined by the structural characteristics of the layer-stranded structure optical cable, the tensile and lateral tension resistance of the layer-stranded structure optical cable without steel wire armoring is seriously insufficient, and the layer-stranded structure optical cable with steel wire armoring has larger weight and volume although a certain tensile and lateral pressure resistance can be provided, so that the tensile and lateral pressure resistance of the layer-stranded structure optical cable during aerial laying is relatively weakened. The factors determine that the layer-stranded structural optical cable is extremely difficult to install in harsh special communication occasions and cannot provide good tensile and lateral pressure resistance capability to ensure the mechanical stability of the optical cable in the special communication occasions.
2. The optical fiber of the bundle tube type structure optical cable has high assembly density, better tensile resistance and high splicing efficiency, and is suitable for relay networks and access networks. The mode of increasing the tensile and side pressure resistance of the optical cable with the beam tube structure is to place two parallel steel wires on two sides or wind a common steel wire armor layer. When a structural mode that two parallel steel wires are placed on two sides is adopted, the optical cable has good tensile resistance, but the lateral pressure resistance is obviously insufficient; when a mode of winding a layer of common steel wire armor layer is adopted, the optical cable has certain lateral pressure resistance, but the tensile resistance is obviously insufficient.
3. The skeleton-type structural optical cable has good lateral pressure resistance and good protection for the optical fiber. The optical fiber has high assembly density, small relative diameter of the optical cable, light weight and convenient laying. But the manufacturing is extremely complex, the production technology is difficult, and the corrosion resistance, the high temperature resistance and the rat and ant resistance are slightly insufficient. If be applied to special communication occasion, not only the input is huge and be difficult to guarantee the stability of communication.
