Description
Technical field
The present invention relates to pipeline cable fields, more particularly to a kind of light-duty high fine density low friction pipeline cable of 5G.
Background technique
5G technology high-speed develops at present, and major operator also actively carries out 5G construction and deployment.The BBU function of 5G will be weighed
Structure is two functional entitys of CU and DU.The cutting of CU and DU function is distinguished with the real-time of process content, and CU equipment is main
Including non real-time wireless higher-layer protocols function, while the also portion of support section core net function sinking and edge application business
Administration, and DU equipment mainly handles the function of physical layer function and real-time demand.The transmission link of the reconstruct of CU and DU, network will
The optical cable that a large amount of high density of demand is laid.
With the continuous development of optical-fiber network technology, have become in communication network access level implementation light entering and copper back irreversible
The trend turned.Micro- cable is the high microstructure optical cable of unit area inner fiber capacity, due to size is small, fiber capacity is big by
It is widely used in pipeline projects construction.But in urban environment, due to urban duct complexity, and there is more old long damaged pipe
Road causes the mode of air-blowing cannot be used to be laid, and micro- cable is only able to use air-blowing and is laid, and not can be carried out dragging and applies
If being not suitable for it in urban duct environment instantly.
At hand with the 5G epoch, urban network there is still a need for carry out route dilatation, but existing city because construction and
Appearance of the city requirement, aerial optical cable can turn into the line system of laying substantially, but existing urban duct resource is limited and is constantly in
Nervous state.In the case, a optical cable that can efficiently utilize pipeline resource is needed in a hurry, it can be in limited pipeline
It accommodates more optical fiber under resource to be communicated, to meet later period construction demand.
Summary of the invention
The object of the invention is that providing a kind of light-duty high fine density low friction pipe of 5G to solve the above-mentioned problems
Road cable.
The present invention through the following technical solutions to achieve the above objectives:
A kind of 5G light-duty high fine density low friction pipeline cable, including oversheath, cable core, the oversheath inside is provided with
Block water watertight layer, is provided with the cable core on the inside of the watertight layer that blocks water, the cable core includes Loose tube, center reinforcemen, institute
It states and is provided with optical fiber on the inside of Loose tube, fiber paste, the Loose tube and the resistance are filled between the optical fiber and the Loose tube
The cable cream that blocks water is provided between water watertight layer, center is arranged between the Loose tube in the center reinforcemen, described outer
Outboard strength members are provided in sheath.
Further setting: the oversheath shape is in flat, the center reinforcemen and Loose tube progress layer hinge
Formula is twisted.
So set, the oversheath uses flat structure, make in an equal amount of pipeline space, shape can more save
Save space resource so as to reach the requirement for improving single pipe fiber capacity, and can be fitted according to actual amount
When increase and decrease optical cable quantity, reduces the unnecessary wasting of resources and reduce preliminary engineering investment.
Further setting: the center reinforcemen, the outboard strength members are phosphating steel wire.
So set, carrying out cable reinforcing using built-in phosphating steel wire, the armor on the outside of optical cable is reduced, the soft of optical cable is made
It is soft more preferably can reduce the overall dimensions of optical cable, reduce the weight of optical cable, make its in construction can more convenient and quicker grasp
Make.
Further setting: the oversheath is using high density polyethylene (HDPE) (PE) and nylon (PA) material.
So set, the oversheath outermost layer is made using nylon material due to the low friction performance of nylon material itself
Its static friction coefficient is 0.15, and the polyethylene material that ordinary optical cable is used due to outer layer, static friction coefficient 0.22,
So that optical cable is carried out frictional force suffered in laid processes in pipeline will be much smaller than friction suffered by ordinary optical cable
Power makes it easier to be laid in complicated pipeline, while also reducing the labor intensity of construction personnel.
Further setting: the outboard strength members are embedded, and the outboard strength members are provided at two on the outer jacket,
And it is symmetrical.
So set, improving the tensile property of optical cable, it can construct as common pipe cable, unlike air-blowing micro-cable must
It must air-blowing construction.
Compared with prior art, beneficial effects of the present invention are as follows:
1, optical cable uses lightweight construction, and outer diameter weight is smaller than conventional cable, can efficiently utilize pipeline space,
Optical cable is in flattened oval shape, fine density more higher than conventional cable can be realized, to improve pipeline in lesser piping volume
Utilization rate；
2, this optical cable uses special material, and the outer protector of optical cable has high glossy and higher hardness, light can be greatly reduced
Frictional force between cable and pipeline and optical cable and optical cable, can with air-blown installation, can also as conventional pipeline cable cable installation in pipe,
Form of construction work is flexible, while can lay jointly with original conventional cable, promotes the space utilization rate of original pipeline, while optical cable
There is no a metal armor layers, it is more preferable that pliability compares conventional armored optical cable, is more advantageous to pipeline laying.
