Abstract
The utility model relates to a stranded 8-shaped optical cable which comprises a steel stranded wire, a hanging wire, a first outer sheath pipe, a second outer sheath pipe and loosing units, wherein the diameter of the first outer sheath pipe is greater than that of the second outer sheath pipe; the first outer sheath pipe is connected with the second outer sheath pipe through the hanging wire; the steel stranded wire is arranged inside the second outer sheath pipe; a plurality of loosing units are arranged inside the first outer sheath pipe; and each loosing unit comprises a sleeve, optical fibers and fiber paste, the optical fibers are arranged in the sleeve, and the fiber paste is filled in the sleeve. The stranded 8-shaped optical cable has a semi-dried stranded optical cable structure and has the beneficial effects of small outer diameter, light weight, convenience in construction and operation and low cost, material saving, is relatively suitable for a metropolitan area network and country communication and especially has wide applciaiton prospect in country communication,.
Description
Technical field
The utility model relates to optical cable, relates in particular to a kind of layer-twisted type 8-shaped optical cable.
Background technology
Present fiber-to-the-home development is just presenting a good situation, so that the networking development rapidly, setting up in the air of network will be used layer-twisted type 8-shaped optical cable, existing layer-twisted type 8-shaped optical cable is because the characteristics weight ratio is heavier, not too can adapt to the new environment that lays, especially for needs between electric pole and the electric pole, between building and the building and make somebody a mere figurehead between electric pole and the building and lay, be difficult to realize that long distance lays requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of lightweight, size is little, easy construction and be fit to the built on stilts layer-twisted type 8-shaped optical cable that lays of long distance, its concrete technical scheme is as follows:
Comprise steel strand wires, messenger wire, the first oversheath pipe, the second oversheath pipe and pine cover unit, the caliber of described the first oversheath pipe is greater than the caliber of the second oversheath pipe, connected by described messenger wire between the first oversheath pipe and the second oversheath pipe, be laid with described steel strand wires in the second oversheath pipe, be provided with some pine covers unit in the first oversheath pipe, described pine cover unit comprises sleeve pipe, optical fiber and fine cream, and described optical fiber is located in the sleeve pipe, is filled with fine cream in the sleeve pipe.
2. layer-twisted type 8-shaped optical cable according to claim 1 is characterized in that, the fiber count in described each pine cover unit is 2～12.
The further design of described layer-twisted type 8-shaped optical cable is, the fiber count in each pine cover unit is 2-12.
The further design of described layer-twisted type 8-shaped optical cable is, oversheath pipe employing PE oversheath pipe, and pine cover unit adopts the PBT sleeve pipe.
The utility model adopts the layer-stranding cable structure of half dry type, and produce thus following beneficial effect: external diameter is little, and is lightweight, the constructability operation, and cost is low, economizes with material, is suitable for Metropolitan Area Network (MAN) and communicates by letter with the rural area, especially having a extensive future in the communication of rural area.
Description of drawings
Fig. 1 is the structural representation of layer-twisted type 8-shaped optical cable.
Among the figure, 1-steel strand wires, 2-messenger wire, 3-the first oversheath pipe, 4-sleeve pipe, 5-optical fiber, the fine cream of 6-, 7-the second oversheath pipe.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
As shown in Figure 1, layer-twisted type 8-shaped optical cable of the present utility model mainly is comprised of steel strand wires 1, messenger wire 2, the first oversheath pipe 3, the second oversheath pipe 7 and pine cover unit.The caliber of the first oversheath pipe 3 is greater than the caliber of the second oversheath pipe 7, and this two oversheaths pipe connects by messenger wire 2, is laid with in the second oversheath pipe and is provided with some pine covers unit in steel strand wires 1, the first oversheath pipe.Pine cover unit is mainly by sleeve pipe 4, and optical fiber 5 and fine cream 6 form, and optical fiber 5 is located in the sleeve pipe 4, is filled with fine cream 6 in the sleeve pipe 4.The oversheath pipe of the present embodiment adopts PE oversheath pipe, and pine cover unit adopts the PBT sleeve pipe.
Place the fiber count of pine cover unit can generally place 2-12, the sleeve pipe external diameter can be Φ 1.8-Φ 2.2.The employing of layer strand is stranded without the central reinforce member formula, lay 65.Cable core is pricked yarn with two and is wrapped up with certain yarn-binding tension, carries out moulding without the steel aluminium strip when adding oversheath, adds messenger wire and steel strand wires stranding when protecting outside extrusion molding.
The product nominal outside diameter is about 13.3 * 7.6mm, and cable heavily is about 70kg/km, and the external diameter of optical cable can be adjusted according to fiber number and the actual concrete condition of using.
This product is to be mainly used in the built on stilts self-bearing type 8 font aerial optical cables that lay, and this cable external diameter is little, lightweight, use the layer-stranding cable structure of half dry type, the constructability operation, cost is low, economize with material, be suitable for Metropolitan Area Network (MAN) and communicate by letter with the rural area, especially having a extensive future in the communication of rural area.
