Abstract
The utility model relates to a compound bunched optical cable. An aramid fiber is made into a rope form and is placed in center as a stiffening member; loose tubes which contain optical fibers and are tightly arranged in manner of SZ stranding and power lines are arranged around the aramid fiber; an armour layer is coated outside the loose tubes and the power lines; and a black high-density polyvinyl plastic outer sheath is coated on the periphery of the armour layer. Water-repellent oleamen is filled in the loose tubes and the armour layer, and the armor layer is aluminium-plastic composite-tape or steel-tape armouring. The two optical cables are combined into one and do not disturb each other, and thereby, construction wiring laying is convenient, the complex construction process is simplified, the construction efficiency is improved and the operation cost is reduced.
Description
Technical field
The utility model relates to optical cable, especially is coated with the optical cable of optical fiber and power line.
Background technology
In view of the BBU+RRU networking plan that adopts in the present TD indoor distributed system, must adopt Optical Fiber Transmission, centralized power supply system between the main equipment, and this kind networking mode need lay optical fiber, cable respectively, and the engineering time is longer, and the conduit of cable wiring is had higher requirement.The inventor needs in conjunction with the practice of construction environment, researches and develops the boundling composite cable that optical fiber and cable are united two into one.But, cable and optical fiber together during stranding the tension adjustment difficulty very big because the power line stretching resistance is bigger, the optical fiber stretching resistance is smaller.Must adjust to equilibrium in the time of stranding, can not damage optical fiber, the stranding success.The balanced power of the test that need not stop just can obtain suitable value.Secondly, the inventor begins the tension rope and adopts steel wire, but finds that hardness is very big, is not easy to lay, and through test of many times and test, has finally selected aramid fiber as central reinforce member.But can not use the bunchy aramid fiber merely because during stranding easily by around in other heart yearns.Also have,, therefore, at first behind the computer simulation Cheng Yuanzhuan interface, just can produce because heart yearn and cross section of optic fibre are long-pending different.
The utility model content
The purpose of this utility model is to provide a kind of boundling composite cable, and optical cable and cable are integrated, and is convenient to the construction wiring, simplified wiring.
For reaching above purpose, solution of the present utility model is:
A kind of boundling composite cable, its center are aramid fiber and similar reinforcement, arrange around aramid fiber and the similar reinforcement and contain the loose sleeve pipe and the power line of optical fiber, and its outside armour that coats, the periphery of armour coats oversheath.
Further, described aramid fiber and similar reinforcement are made rope form.
Described loose sleeve pipe and power line are closely arranged in SZ strand mode.
Be full of greasy for preventing water in described loose sleeve pipe and the armour.
Described oversheath is a high density black vinyon.
Described armour is aluminium-plastic tape or steel-tape armouring.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
1, optical cable and cable are united two into one, transmission frequency bandwidth, the message capacity of the optical cable in the beam tube are big, but and both transmission of digital signals, cable can electric energy transmitting simultaneously.Because optical fiber is nonmetal medium, the light signal that transmits in the optical fiber is not subjected to electromagnetic induction.Bunched cable is exactly a light harvesting, electric in one, and does not disturb mutually, and the cloth wire routing of being convenient to construct has been simplified complicated construction procedure, has improved efficiency of construction, reduces operating cost.
2, realized Optical Fiber Transmission, centralized power supply system between base station, BBU (indoor baseband processing unit), the RRU main equipment, promoted network security, avoided RRU (far-end RF module) under the situation that adopts non-centrally connected power supply, because the fault of electric power system (tripping operation, power failure) causes the local paralysis of a certain unit channel of indoor distributed system, causes the economic loss that therefore causes.
3, adopt boundling composite cable technology, in the networking process, zoom out the distance between BBU and the RRU to greatest extent, signal is little by fiber transmission attenuation, integral body has reduced the feeder loss of system, has avoided because of the puzzlement of a centrally connected power supply difficult problem a plurality of RRU being concentrated the mode that feeder line zooms out that relies on of placing.
4, boundling composite cable highly versatile, transmission signals is strong, and capacity is big, and simultaneously optical fiber and copper conductor interference signal not mutually in the bunched cable is particularly suitable for BBU+RRU combination covering scheme, can be widely used in indoor and outdoor networkings coverings such as mansion, housing-group, large stadium.

Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
Boundling composite cable GYTZS24B1-RV 4 * 6mm
2(wherein " 24 " represent 24 core fibres to type, " 4 " expression number of electrical lines, 6 the expression power lines the area of section square number) the layer-stranding cable center with many aramid fibers 5 as stiffener, aramid fiber 5 is to be made into rope form earlier, place the center again, closely arranging loose sleeve pipe 4 and the power line 3 that includes multi-core fiber and ointment in SZ strand mode on every side, the gap of pine sleeve pipe 4 and power line 3 is full of greasy for preventing water, outside aluminium-plastic tape 2 (GYTS type) or the coated steel band armouring of coating, oversheath 1 adopts high density black vinyon, is coated on aluminium-plastic tape 2 outsides.The aramid fiber tensile strength difference of different model, for boundling composite cable of the present utility model, be made into the rope form aramid fiber and need possess enough tensile strength, behind optical cable stranding together, some variations take place because of stranding in its tension force, increase the stiffener of aramid fiber, can reduce the influence that in the engineering construction process, pulls repeatedly optical fiber as tension.This optical cable total cross-section blocks water, and has the advantage of low-loss, low chromatic dispersion, is applicable to long distance communication circuit and city Access Network, the pipeline of local area network communication or built on stilts laying.
