Embodiment
embodiment 1
Ask for an interview Fig. 1 and Fig. 2, air-blowing optical fiber is used in a kind of communication, and it is made up of fibre core 1, the covering 2 be positioned at outside fibre core, the coat 3 be positioned at outside covering, it is characterized in that the outer spaced raised line 4 of cause of described coat and groove are formed; With on the xsect of coat axes normal: the shape of described raised line is triangle, and the summit of all raised lines is positioned on same circumference 5.
embodiment 2
Ask for an interview Fig. 3 and Fig. 4, air-blowing optical fiber is used in a kind of communication, and it is made up of fibre core 1, the covering 2 be positioned at outside fibre core, the coat 3 be positioned at outside covering, it is characterized in that the outer spaced raised line 4 of cause of described coat and groove are formed; With on the xsect of coat axes normal: the top of described raised line is circular arc, and the top of all raised lines is positioned on same circumference 5.
Embodiment 1 or the one communication air-blowing optical fiber described in embodiment 2, is characterized in that the shape of described groove is triangular prism shaped; Also can be four prism type or other suitable shape.
Embodiment 1 or the one communication air-blowing optical fiber described in embodiment 2, is characterized in that described raised line parallels with the axis of coat.
embodiment 3
Ask for an interview Fig. 5, air-blowing optical fiber is used in a kind of communication, and it is made up of fibre core 1, the covering 2 be positioned at outside fibre core, the coat 3 be positioned at outside covering, it is characterized in that the outer spaced raised line 4 of cause of described coat and groove are formed; With on the xsect of coat axes normal: the top of described raised line is circular arc, and the top of all raised lines is positioned on same circumference 5; Described raised line distributes in the mode of one direction spiral.
Certainly, the one communication air-blowing optical fiber described in the utility model, it is all made up of fibre core, the covering be positioned at outside fibre core, the coat be positioned at outside covering, and the outer spaced raised line of cause of described coat and groove are formed; With on the xsect of coat axes normal: the top of all raised lines is positioned at circumferentially same.
One communication air-blowing optical fiber described above, is characterized in that the axis of described fibre core, covering, coat overlaps.
One communication air-blowing optical fiber described above, is characterized in that the material of described fibre core is silicon dioxide.
One communication air-blowing optical fiber described above, is characterized in that the refractive index of described covering is greater than the refractive index of fibre core; The refractive index of coat is greater than the refractive index of covering.
One communication air-blowing optical fiber described above, is characterized in that the diameter of described coat is 0.45 ~ 1.2mm.
In the utility model, the outer spaced raised line of cause of the coat due to air-blowing optical fiber and groove are formed, and the existence of groove, makes optical fiber be provided with flow guide function, make it be suitable for air-blown installation; When the shape of groove is spiral, flow guide effect is stronger, makes that resistance during air-blowing is less, speed of application is faster.Because the final diameter of the coat of the air-blowing optical fiber in the utility model is only 0.45 ~ 1.2mm, therefore, the butterfly leading in cable of the 2mm × 3mm compared to existing technology, less space can be occupied, demand for pipe interior space is lower, therefore just can enter easily in the pipeline laid in advance when lower blast pressure, even if wherein existing many cables also can successfully pass, thus do not affect the original decoration of family.
Therefore, the utility model has space hold and less, more easily lays, for the little space requirement left in pipeline, the Advantageous Effects not affecting original decoration.
The utility model is not limited to above-mentioned preferred forms, and should be appreciated that design of the present utility model can be implemented to use by other various forms, they drop in protection domain of the present utility model equally.
