Abstract
A microgroove type air-blowing high-performance optical fiber unit comprises optical fibers and an outer protective layer of the optical fibers, wherein a cured resin is arranged between the optical fibers, and axial microgrooves are arranged on the surface of the outer protective layer. The utility model discloses owing to be equipped with the axial microgroove on outer sheath surface, when the air-blowing laid, the area of contact of outer sheath and pipeline inner wall was little, has reduced the frictional force with the pipeline inner wall, consequently can increase the air-blowing distance in the pipeline, satisfied the needs that long distance air-blowing laid, reduced the optic fibre contact, improved the optic fibre utilization ratio. Moreover, because be equipped with cured resin between the optic fibre, improved the utility model discloses a tensile, anti-bending performance.
Description
Technical field
The utility model relates to a kind of telecommunication optical fiber unit, in particular for the fiber unit of air-blown installation in pipeline.
Background technology
Have the generally outdoor occasion use between the indoor scenarios or LAN (Local Area Network) of access net system, between the sub-district of fiber unit of air-blown installation in pipeline now, its structure is generally optical fiber and coats outer jacket outward.This fiber unit is in pipeline during air-blown installation, because the friction of outer jacket and inner-walls of duct is big, so air-blowing apart from weak point, can not be satisfied and lay needs.
Summary of the invention
The novel purpose of this reality is the deficiency that overcomes existing air-blowing fiber unit, a kind of microflute type air-blowing high-performance optical fiber unit is provided, can be in pipeline reduce the friction of outer jacket and inner-walls of duct during air-blown installation, be increased in air-blowing distance in the pipeline, satisfy long needs apart from air-blown installation.
A kind of microflute type air-blowing high-performance optical fiber unit that the utility model provides comprises optical fiber and outer jacket thereof, is provided with the curing resin between optical fiber, is provided with axial microflute on the outer jacket surface.
The beneficial effects of the utility model are: owing to be provided with axial microflute on the outer jacket surface, during air-blown installation, the contact area of outer jacket and inner-walls of duct is little, reduced friction with inner-walls of duct, thereby can be increased in air-blowing distance in the pipeline, satisfy long needs, reduce the optical fiber contact, improve the optical fiber utilization factor apart from air-blown installation.And, owing between optical fiber, be provided with the curing resin, improved tension of the present utility model, warping resistance performance.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, optical fiber, 2, solidify resin, 3, outer jacket, 4, axial microflute.
Embodiment
With reference to Fig. 1, adopt earlier and solidify resin 2 together several optical fiber 1 adhering and solidifying, clad surface is provided with the outer jacket 3 of several axial microflutes 4 again, promptly makes the utility model.
Claims (1)
1. a microflute type air-blowing high-performance optical fiber unit comprises optical fiber and outer jacket thereof, it is characterized in that being provided with between optical fiber the curing resin, is provided with axial microflute on the outer jacket surface.
