Abstract
The utility model discloses a fan shaped loose casing strength optical cable which is characterized in that a secondary coated loose casing optical fiber and a composite fan shaped loose casing pipe well are filled with aramid fiber or steel wires as strengthening ribs, which forms the fan shaped loose casing optical fiber. Then the fan shaped loose casing optical fiber is twisted at the periphery of a central strengthening element, which forms a circular cylinder. The circular cylinder is wrapped with polyester bands. Metal plastic composite bands and outer sheaths are wrapped longitudinally. The structure of the optical cable has better tensile and lateral pressure resistant strength, waterproof properties and temperature characteristic. More optical cable cores are arranged and the connection is convenient, and therefore, the utility model is suitable for being used by various laying modes and long distance trunk lines. Compared with an optical cable with the same number of cores, the utility model has light volume and good bending property. The utility model is suitable for being erected and being used indoors.
Description
The powerful optical cable of fan-shaped pine cover is the transmission medium of optical communication.
The optical cable of practicability should manufacture, install lay, all should be comparatively desirable aspect using three.The cable configuration of home and abroad prior art has layer strand optical cable, skeleton optical cable, beam tube or armouring scallop wire optical cable etc. at present.The optical cable of these versions has characteristics separately, as layer strand optical cable temperature characterisitic and tensile strength is preferably arranged, and be easier to control excess fiber length during manufacturing, but the lateral pressure resistant ability is relatively poor; The skeleton optical cable is because the protection of skeleton, and it has lateral pressure resistant performance preferably, but excess fiber length control difficulty when making, big core is counted optical cable and also is difficult for realizing; Though beam tube or armouring scallop wire optical cable have every performances such as good tension, lateral pressure resistant, connect inconvenience between the optical cable, it is bigger that big core is counted the optical cable volume, and it is heavy that built on stilts use seems.
The purpose of this utility model is to manufacture and design a kind of novel cable configuration, makes it have stronger tension, the mechanical property of lateral pressure resistant, and temperature characterisitic is preferably arranged again, is convenient to simultaneously make and install, and increases optical cable core number and reduces cost.
Fan-shaped pine is overlapped powerful optical cable and is made of by multiple loose tube fiber, protective layer, vertical genus plastics composite band covered with gold leaf and oversheath central reinforce member, cushion, secondary, it is characterized in that secondary is formed compound fan-shaped loose tube fiber by filler reinforcement muscle in multiple loose tube fiber, compound fan-shaped loose sleeve pipe, the sleeve pipe.The shell material of compound fan-shaped loose tube fiber is plastics, and as polyamine fat, nylon, tygon, Polyvinylchloride etc., its shape is fan-shaped; The material of reinforcing steel comprises steel wire, aramid fiber etc.A plurality of compound fan-shaped loose tube fibers are indulged mutually closely, equably and are wrapped in the central reinforce member periphery that has cushion, and are twisted into right cylinder; The face of cylinder after stranded closely holds protective layer, the optional polyester band of its material, nonwoven fabrics etc.; Vertical again plastics composite band and the oversheath of belonging to covered with gold leaf forms complete optical cable new structure.
The utlity model has following advantage, owing to adopt compound fan-shaped loose tube fiber structure, make cable configuration stable, possess and be better than the advantage of a layer strand optical cable, skeleton optical cable, beam tube or armouring scallop wire optical cable three kinds of structures, therefore have advantages of higher tensile strength, lateral pressure resistant intensity and temperature characterisitic preferably.Be convenient to control excess fiber length when making simultaneously, be convenient to during use interconnect, can accomplish that volume is little, the core number is many, and cost is low.
Description of drawings:
1. central reinforce member 2. cushions 3. secondaries are by multiple loose tube fiber
4. protective layer 5. vertical golds filled belong to plastics composite band 6. oversheaths
7. compound fan-shaped loose tube fiber 8. reinforcing steels
Embodiment
