Abstract
The invention relates to the technical field of light transmission and particularly relates to a composite cable used for pulling away. The composite cable is provided with two power lines which are symmetrically arranged and cling together and optical fiber subcables distributed at the two sides of the power lines. The centers of the optical fiber subcables are optical fibers wrapped with tight sleeve layers, each of which is externally wrapped with a layer of silvalin which is externally provided with a layer of subcable sheath. The power lines and the subcables are wrapped by a wrapping tape after being stranded together. A layer of outer sheath wraps the periphery of the wrapping tape. The two power lines are symmetrically arranged and cling together so that a tensile role is played and optical fibers at the two sides can be prevented from being extruded and the transmission performance of the optical fibers can be prevented from being influenced. The power lines and the subcables are wrapped with the layer of wrapping tape after being stranded so that during production of the outer sheath, a condition that due to high temperature, the performance of insulating layers of the power lines is damaged and bonding of the outer sheath and the subcable sheaths is caused happens is prevented and the optical cable can be ensured to be better in temperature performance and the power lines and the optical fibers are aggregated in the same cable and can be laid at one time so that construction cost is reduced.
Description
Technical field
The present invention relates to optical transport technology field, refer in particular to a kind of optoelectronic composite cable for wireless base station fiber optic stretch.
Background technology
At present, in a lot of networking, both having needed can the optical cable of transmitting optical signal, and needing again can the power line of transmission current, and under normal conditions, optical cable and power line need to lay at twice, and efficiency of construction is low, and takies conduit resource.Have optoelectronic composite cable subsequently, can optical fiber be realized and power line synchronously lays, lifting construction operating efficiency, but due to fault of construction, existing optoelectronic composite cable is mostly only applicable to general outdoor laid, and what be not suitable for base station fiber optic stretch in mobile communications network lays environment.
Summary of the invention
The object of the invention is to the defect overcoming prior art, a kind of zooming out of base station fiber optic stretch that be used for power line and optical fiber combined in same cable is provided to use composite rope, can disposablely lay, reduce construction cost, promote tensile property again, so that in tension process, optical fiber can be prevented to be squeezed and to affect the transmission performance of optical fiber.
For achieving the above object, the present invention adopts following technical scheme:
One zooms out with composite rope, this composite rope has two and is symmetrical arranged and the power line be close together and be distributed in the sub-cable of optical fiber of power line bilateral, optical fiber Zi Lan center is the coated optical fiber of tight sleeve layer, and tight sleeve layer bag one deck silvalin more outward, is provided with the sub-cable sheath of one deck outside silvalin; Described power line and sub-cable twist together with a constant pitch, and periphery is wrapped up by band, and the coated one deck oversheath in band periphery.
Described band inner circumferential is also provided with one deck assistant reinforcement layer.
Also be provided with between described band and oversheath and tear rope.
Described band is that longitudinal direction is coated or winding is coated.
Described power line is insulated conductor, and conductor is that single copper cash or many copper cash twist together formation.
Composite rope provided by the invention, its two power lines are symmetrical arranged and are close together, and have both played the effect of tension, and in tension process, the optical fiber of bilateral can be prevented to be squeezed and to affect the transmission performance of optical fiber.Power line and sub-cable stranded after periphery wrap up one deck band, when oversheath is produced, can not Yin Gaowen and destroy the performance of power line insulating barrier and cause oversheath and sub-cable sheath to stick together situation, ensure that optical cable has more excellent temperature performance.Power line and optical fiber combine in same cable, for the occasion needing transmission current and light signal simultaneously, can disposablely lay, and reduce construction cost, and the external diameter of cable are little, can save conduit resource.
accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of one preferred embodiment of the present invention;
Accompanying drawing 2 is the structural representation of its two preferred embodiment of the present invention.
embodiment:
Be described further below with reference to the technique effect of accompanying drawing to design of the present invention, concrete structure and generation, to understand object of the present invention, characteristic sum effect fully.
Consult shown in Fig. 1, for the structural representation of one preferred embodiment of the present invention, its relevant one zooms out with composite rope, this composite rope has two and is symmetrical arranged and the power line 1 be close together and be distributed in the sub-cable of optical fiber of power line 1 bilateral, power line 1 is insulated conductor, and its conductor is that single copper cash or many copper cash twist together formation.Optical fiber Zi Lan center is the coated optical fiber 2 of tight sleeve layer 3, and the outer bag one deck silvalin 4 again of tight sleeve layer 3, plays drawing-resistant function, increase the tensile strength of optical fiber 2.Be provided with the sub-cable sheath 5 of one deck outside silvalin 4, sub-cable sheath 5 adopts fire proofing to make.Described power line 1 and sub-cable twist together with a constant pitch, and periphery is wrapped up by band 6, and the coated one deck oversheath 7 in band 6 periphery, outer jacket 7 adopts fire proofing to make.
Band 6 can adopt polyester band, and also can adopt nonwoven fabrics band or other suitable material, its set-up mode can adopt longitudinal packet mode, also can adopt winding packet mode.The effect of band 6 is when oversheath 7 is produced, can not Yin Gaowen and destroy the performance of power line 1 insulating barrier and cause oversheath 7 and sub-cable sheath 5 to stick together situation, ensures that optical cable has more excellent temperature performance.
Two power lines 1 of the present invention are symmetrical arranged and are close together, and have both played the effect of tension, and in tension process, the optical fiber 2 of bilateral can be prevented to be squeezed and to affect the transmission performance of optical fiber.Power line 1 and optical fiber 2 combine in same cable, for the occasion needing transmission current and light signal simultaneously, can disposablely lay, and reduce construction cost, and the external diameter of cable are little, can save conduit resource.
Consult shown in Fig. 2, for the structural representation of its two preferred embodiment of the present invention, it is also provided with one deck assistant reinforcement layer 8 in band 6 inner circumferential further on the basis of Fig. 1 embodiment, and whether this assistant reinforcement layer 8 is selected to arrange as required, a main drawing-resistant function, improves the tensile property of optical cable; General employing aramid fiber yarn, glass fiber yarn etc.The present embodiment is also also provided with and tears rope 9 between band 6 and oversheath 7, and whether this tears rope 9 is also select as required to arrange, and mainly facilitates fiber cable jacket stripping, lifting construction operating efficiency.
Although describe preferred embodiment of the present invention by reference to the accompanying drawings above-mentioned, the present invention should not be restricted to and above description and the identical structure of accompanying drawing and operation.Concerning those skilled in the art; also can make many improvement and change to above-described embodiment when not exceeding design of the present invention and scope by logical analysis, reasoning, or a limited experiment, but these improve and change all should belong to the scope of protection of present invention.
