Description
Technical field
The utility model relates to optical cable technology field more particularly to a kind of strip-like flat optical cables.
Background technique
Along with the rapid development of IT wave, optical cable plays an increasingly important role in communication process, makees
For the important medium that information is propagated, the transinformation of optical fiber is most important, existing facing to more and more massive informations
Single fiber cable more seems awkward in transmittability, and more single fiber cables, which are simply banded together, to be made
With then it is low to be easy loose and tensile capacity for it, and the outer wall of optical cable is also easily damaged, a kind of with big it is therefore necessary to provide
The optical cable of capacity communication ability meets growing use demand, preferably serves users.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of strip-like flat optical cables.
The utility model proposes a kind of strip-like flat optical cable, comprising: fibre ribbon, inner sheath, enhancement layer, oversheath；
Fibre ribbon includes multiple parallel longitudinal fiber units, and multiple fiber units are sequentially arranged and axis is located at same put down
On face, each fiber unit includes the fibre core for being located at middle part, the clad being coated on outside fibre core and is coated on outside clad
Hard-pressed bale layer；Inner sheath is extruded in outside whole fiber units, and enhancement layer is coated on outside inner sheath, and oversheath is coated on reinforcement
Layer is external.
Preferably, enhancement layer is made of aramid fiber.
Preferably, oversheath outer wall is equipped with multiple first and easily tears slot, and each first easily tears slot position in two neighboring optical fiber list
Axis between member and along fiber unit extends.
Preferably, oversheath easily tears slot side far from described first and easily tears slot equipped with multiple second, and each second easily tears slot
With one first easily tear slot it is corresponding arrange.
Preferably, tear rope is equipped in inner sheath.
In the utility model, the strip-like flat optical cable proposed, fibre ribbon includes multiple parallel longitudinal fiber units, more
A fiber unit is sequentially arranged and axis is in the same plane, and each fiber unit includes the fibre core for being located at middle part, is coated on
Clad outside fibre core and the hard-pressed bale layer being coated on outside clad；Inner sheath is extruded in outside whole fiber units, is reinforced
Layer is coated on outside inner sheath, and oversheath is coated on outside enhancement layer.By the strip-like flat optical cable of above-mentioned optimization design, guarantee
The flexibility of optical cable, while banded structure is convenient for the arrangement of optical cable and the removing of multiple fiber units.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of strip-like flat optical cable structural schematic diagram.
Specific embodiment
As shown in FIG. 1, FIG. 1 is the utility model proposes a kind of strip-like flat optical cable structural schematic diagram.
Referring to Fig.1, the utility model proposes a kind of strip-like flat optical cable, comprising: fibre ribbon, inner sheath 2, enhancement layer 3,
Oversheath 4；
Fibre ribbon includes multiple parallel longitudinal fiber units 1, and multiple fiber units 1 are sequentially arranged and axis is positioned at same
In plane, each fiber unit 1 includes the fibre core 11 for being located at middle part, the clad 12 being coated on outside fibre core 11 and is coated on
Hard-pressed bale layer 13 outside coating 12；Inner sheath 2 is extruded in outside whole fiber units 1, and enhancement layer 3 is coated on outside inner sheath 2,
Oversheath 4 is coated on outside enhancement layer 3.
In the present embodiment, the strip-like flat optical cable proposed, fibre ribbon includes multiple parallel longitudinal fiber units, more
A fiber unit is sequentially arranged and axis is in the same plane, and each fiber unit includes the fibre core for being located at middle part, is coated on
Clad outside fibre core and the hard-pressed bale layer being coated on outside clad；Inner sheath is extruded in outside whole fiber units, is reinforced

The flexibility of optical cable, while banded structure is convenient for the arrangement of optical cable and the removing of multiple fiber units.
In a specific embodiment, enhancement layer 3 is made of aramid fiber, does not influence the weight of optical cable, while guaranteeing machine
Tool intensity.
In order to further be convenient for the removing of fiber unit, in other specific embodiments, 4 outer wall of oversheath is equipped with multiple
First easily tears slot, and each first easily tears slot position between two neighboring fiber unit 1 and extend along the axis of fiber unit 1.
In further specific embodiment, oversheath 4 easily tears slot side far from described first and easily tears equipped with multiple second
Slot, each second easily tear slot with one first easily tear slot it is corresponding arrange.
In other specific embodiments, tear rope 5 is equipped in inner sheath 2.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
