Description
Technical field
The utility model relates to communications optical cable technical field, particularly a kind of pneumatic transmission micro optical cable.
Background technology
Optical cable is to be mainly made up of light transmitting fiber and plastic protective sleeve pipe and plastic peel.Optical cable is the main delivery means of the various Information Networks of current information society.
The system of laying of optical cable comprises overhead type, direct burial and duct type, duct type is generally air-blowing optical cable mounting means, adopt the mode that blows of high pressure draught by optical cable lowering in the silicon core pipe of pre-plugged, blow cable machine the pressurized air of high pressure, high speed is blown into silicon core pipe, high pressure draught promotes sealing gland piston, the sealing gland piston that is connected to like this end of cable forms the uniform pulling force of a setting to optical cable, meanwhile blow cable machine hydraulic track conveying mechanism clamping optical cable and be fed forward, erection mode is simple and practical like this.In recent years, fiber-to-the-home development is very rapid, and each state is all carrying out networking on a large scale.Optical cable is applied to the Main Means that has become the communication network development in pipeline by the method for pneumatic transmission.
The high speed development of the communications industry has also brought keen competition more, and all common carriers also all start to pay attention to and make every effort to reduce all possibilities of network construction cost in carrying out networking on a large scale.At present, operator, in the time carrying out dilatation, conventionally need again change new pipeline and optical cable is installed, not only long construction period, and cause the raising of cost.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of pneumatic transmission micro optical cable of constructing rapid, cost-saving, density of optic fibre is high is provided.
The purpose of this utility model is achieved through the following technical solutions: pneumatic transmission micro optical cable, it comprises an outer tube, in described outer tube, be provided with multiple miniature son pipes, in described multiple miniature sub-pipe, have at least in a miniature sub-pipe micro optical cable is installed, described micro optical cable comprises optical fiber, fine cream, sleeve structure and oversheath, and sleeve structure clad optical fiber is filled fine cream in sleeve structure, oversheath is coated on sleeve structure outside, in described sleeve structure, is coated with multifiber.
Described sleeve structure comprises non-metallic casing layer and is coated on the aramid yarn enhancement Layer outside non-metallic casing layer.
Described sleeve structure is stainless steel flexible hose.
The outside surface of described oversheath is along being circumferentially evenly equipped with the fin extending vertically.
The utlity model has following advantage: the utility model can be installed micro optical cable as required in the sub-pipe of installing within the outer tube, in the time of needs dilatation, can lay fast optical fiber, construction rapidly.Compare existing technique and can only carry out the replacing of optical cable, again lay new optical cable, greatly saved cost and time.The utility model makes operator in the time constructing, and blows as required cable in batches, has reduced just construction cost of project; Increase paving when optical fiber, blow that cable speed is fast, distance, improved work efficiency; Can carry out flexibly Wei Lan branch, improve operation maintenance quality; Density of optic fibre is high, effectively improves unit area density of optic fibre.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, pneumatic transmission micro optical cable, it comprises an outer tube 1, in described outer tube 1, be provided with multiple miniature son pipes 2, in described multiple miniature son pipe 2, have at least in a miniature son pipe 2 micro optical cable 3 is installed, described micro optical cable 3 comprises optical fiber 4, fine cream 5, sleeve structure 6 and oversheath 7, sleeve structure 6 clad optical fibers 4, the fine cream 5 of the interior filling of sleeve structure 6, oversheath 7 is coated on sleeve structure 6 outsides, in described sleeve structure 6, is coated with multifiber 4.Micro optical cable 3 can be blown into very easily in miniature son pipe 2 in needs, therefore, needn't prepare for later unknowable growth at During Initial Stage Construction, has reduced initial stage construction cost.
Described sleeve structure 6 is stainless steel flexible hose 10, and optical fiber 4 is arranged at stainless steel flexible hose 10 inside, and at the fine cream 5 of stainless steel flexible hose 10 inner filling, oversheath 7 is coated on the outside of stainless steel flexible hose 10.
The outside surface of described oversheath 7 is along being circumferentially evenly equipped with the fin 11 extending vertically, and the cross section of described fin 11 is circular arc or triangle.This structure makes long-pending the increasing of sleeve surface and weight saving, and while therefore construction, thereby contributing to micro optical cable 3 to be dragged by air is blown into micro optical cable 3 in miniature son pipe 2 smoothly, can prevent that oversheath 7 from being abraded by inner-walls of duct simultaneously.
Described micro optical cable 3 is 2～48 core optical cables.
The course of work of the present utility model is as follows: the utility model can be installed micro optical cable 3 as required in the sub-pipe being arranged in outer tube 1, in the time of needs dilatation, can lay fast optical fiber 4, and construction rapidly.Compare existing technique and can only carry out the replacing of optical cable, again lay new optical cable, greatly saved cost and time.The utility model makes operator in the time constructing, and blows as required cable in batches, has reduced just construction cost of project; Increase paving when optical fiber 4, blow that cable speed is fast, distance, improved work efficiency; Can carry out flexibly Wei Lan branch, improve operation maintenance quality; Optical fiber 4 density are high, effectively improve unit area optical fiber 4 density.
