Abstract
The utility model relates to a microgroove air-blow high-performance optical fiber unit, comprising optical fibers and an outer protective layer of the optical fibers, wherein cured resin is arranged among the optical fibers; and the surface of the outer protective layer is provided with axial microgrooves. As the optical fiber unit is provided with the axial microgrooves at the surface of the outer protective layer, when air-blow laying is performed, the contact area of the outer protective layer and the internal wall of a pipeline is small, the frictional force of the outer protective layer and the internal wall of the pipeline is reduced, so that the air-blow distance in the pipeline is increased, thereby meeting the requirements of long-distance air-blow laying, reducing connection points of the optical fiber and improving the utilization ratio of the optical fibers. In addition, as the cured resin is arranged among the optical fibers, the tensile property and the bending-resistant property of the optical fiber unit are improved.
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.
