Description
Technical field
It the utility model is related to a kind of aerial earth wire, and in particular to a kind of high bending-resistant type OPGW, belong to
Fiber optic cable communications domain technology field.
Background technology
Optical fiber makes somebody a mere figurehead composite ground wire (abbreviation OPGW) with ground wire and the dual-use function of optical cable, in power communication industry
It is widely used.OPGW cable configurations include light unit and armor, and armouring unit undertakes ground wire function, and light unit is held
Carry on a shoulder pole OPGW optical fiber communication functions.Wherein, light unit is mainly made up of optical fiber, fine cream and protection pipe, and optical fiber is light unit
Core, it is a kind of fragile article again, and is declined intolerant to drawing, not anti-extrusion, the transmission that its stress directly affects optical signal
Subtract, thus have significant impact to the reliability and life expectancy of OPGW longtime runnings.Under some limiting conditions, as cruelty is applied
Work, optical cable discontinuity flexural deformation can make it that；Typhoon causes circuit frequently to shake, the icing in extremely cold severe area, greatly across
Away from region etc., optical fiber attenuation can be all set to become big or even damage.
Utility model content
The utility model is the defects of overcoming prior art, and the utility model purpose is to provide for a kind of high bending-resistant type light
Fine composite overhead ground wire, it can use, its superior dynamic fatigue resistance energy, can offset under special supply of material region or particular surroundings
High wind, icing, large span etc. cause the influence that optical fiber attenuation increases, and meet access network small-bend radius, close installation, construction
Convenient demand.
The technical solution adopted in the utility model is：A kind of high bending-resistant type OPGW, including light unit and
Metal wire of the twisted wire outside the light unit；The light unit includes stainless steel tube and more be arranged in the stainless steel tube
Special optical fiber；Fine cream is filled between more special optical fibers in the stainless steel tube.
Further improved as the utility model, it is central tubular or layer-twisted type structure that the stainless steel tube, which is,.
Further improved as the utility model, the metal wire includes electrician's aluminum-clad steel wire and sets twisted wire described
The aluminium alloy wire of electrician's aluminum-clad steel wire outer layer；Electrician's aluminum-clad steel wire twisted wire is outside the light unit.
Further improved as the utility model, the special optical fiber is that G657 bends unwise optical fiber.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
High bending-resistant type OPGW of the present utility model, employing extraordinary bend insensitive fiber gathers around optical cable
Have a less PMD Coefficient, optical fiber macrobend and it is micro-bend caused by light leakage it is small, transmission bandwidth is wider, and transmission rate is more
Height, use range is wide, and Line Attenuation is low；Aerial earth wire outer layer uses AAL aluminium alloy wires, adds the pliability of optical cable, improves
The bendability of optical cable, meet access network small-bend radius, close installation, it is easy for construction the needs of.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is the signal of high bending-resistant type OPGW central tubular structural section figure of the present utility model
Figure；
Accompanying drawing 2 is the schematic diagram of high bending-resistant type OPGW layer-twisted type structural section figure of the present utility model；
In figure：1- light units；2- metal wires；11- stainless steel tubes；12- special optical fibers；13- fibre cream；21- electrician's aluminium Baogang
Line；22- aluminium alloy wires.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in accompanying drawing 1,2, a kind of high bending-resistant type OPGW of the present utility model, including the He of light unit 1
Metal wire 2 of the twisted wire outside light unit 1；Light unit 1 includes stainless steel tube 11 and special optical fiber 12, in each stainless steel tube 11
Special optical fiber has 8-72 roots, and fine cream 13 is filled between more special optical fibers.Wherein, special optical fiber is that new G657 is curved
Qu Bumin optical fiber.New G657 bend insensitive fibers are employed, traditional G652 single-mode fibers is instead of, possesses optical cable
Less PMD Coefficient, optical fiber macrobend and it is micro-bend caused by light leakage it is small, transmission bandwidth is wider, and transmission rate is higher,
Use range is wide, and Line Attenuation is low.
Wherein, it is center or layer-twisted type structure that stainless steel tube 11, which is,；Metal wire 2 includes electrician's aluminum-clad steel wire 21 and set to twist
Aluminium alloy wire 22 of the line in the outer layer of electrician's aluminum-clad steel wire 21；Electrician's aluminum-clad steel wire twisted wire is outside the light unit.This practicality
NEW TYPE OF COMPOSITE aerial earth wire outermost layer uses AAL aluminium alloy wires, instead of original ACS electrician's aluminum-clad steel wire, adds optical cable
Pliability, improve the bendability of optical cable, meet access network small-bend radius, close installation, it is easy for construction the needs of.
It the above is only concrete application example of the present utility model, do not form any limit to the scope of protection of the utility model
System.All technical schemes formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
