Description
Technical field
The utility model relates to optical transport technology field, refers 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 purpose of this utility model is 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 utility model 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.
The composite rope that the utility model provides, 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 the utility model one preferred embodiment;
Accompanying drawing 2 is the structural representation of its two preferred embodiment of the utility model.
embodiment:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1, for the structural representation of the utility model one preferred embodiment, 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, oversheath 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 utility model 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 utility model, it is also provided with one deck assistant reinforcement layer 8 in band 6 inner circumferential further on the basis of Fig. 1 embodiment, 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 utility model by reference to the accompanying drawings above-mentioned, the utility model 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 the utility model design and scope by logical analysis, reasoning, or a limited experiment, but these improve and change all should belong to the claimed scope of the utility model.
