Abstract
The invention relates to a tension-resisting circular optical cable which comprises optical fibers (1). The tension-resisting circular optical cable further comprises loose sleeves (2), an inner sleeve (3), a tension-resisting body (4), an electromagnetic shielding layer (5) and an outer jacket (6). Each loose sleeve (2) wraps at least one optical fiber (1). A combination part of the loose sleeves (2) and the optical fibers (1) is arranged inside the inner sleeve (3). The tension-resisting body (4) is arranged on the outer side of the inner sleeve (3). The electromagnetic shielding layer (5) is arranged on the outer side of the tension-resisting body (4). The outer jacket (6) is arranged on the outer side of the electromagnetic shielding layer (5). The tension-resisting circular optical cable has the advantages that the tension-resisting body is arranged, therefore, the tension-resisting performance is good, the bending capacity is good, and the optical fibers can be protected against damage when external force is exerted on the tension-resisting circular optical cable; meanwhile, the electromagnetic shielding layer is arranged, therefore, the influences by electromagnetic noise can be avoided, and the transmission quality is improved.
Description
Technical field
The present invention relates to optical cable, particularly a kind of tension circular optical cable.
Background technology
In informationized society, optical cable, as the important carrier of communication network, is widely used in the indoor and outdoor communication, progressively to user side, extends.Because the environment that optical cable arranges is day by day various, answer environmental requirement, optical cable easily branched, tensile property good, wear-resisting, waterproof, light signal are not subjected to that electromagnetic noise affects etc., and functional requirement becomes a kind of trend, to adapt to complex environment.
Chinese patent application number: 201110304510.4, a kind of ruggedized fiber optic cable is disclosed, this patent of invention comprises tightly packaged fiber, is coated on tightly packaged fiber outer enhancement Layer and restrictive coating, and described enhancement Layer comprises high-strength layer.High strength yarns has good mechanical-physical intensity, can strengthen the mechanical-physical ability such as lateral pressure resistant, tension of optical cable, makes optical cable adapt to better outdoor complex environment.This patent of invention is mainly applied high-intensity layer, and the layer structure is very thin, has therefore strengthened significantly the producting process difficulty of optical cable.
Chinese patent application number: 201220363366.1 disclose a kind of photoelectricity mixing ripple cable; comprise optical communication element, communication unit and oversheath; this optical communication element comprises at least one pair of fiber cores; this communication unit comprises at least one electronic communication link; its carrying of the ripple cable of this structure and resistance to tension are poor; the cable major part is exposed in extraneous air, and after long-term exposing to the sun and rain, the protective effect that the outer jacket of cable plays is little.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of circular optical cable that stronger tensile property, light signal are not affected by electromagnetic noise that has is provided.
Purpose of the present invention is achieved through the following technical solutions: a kind of tension circular optical cable, comprise optical fiber, it also comprises loose sleeve pipe, inner sleeve, tension element, electro-magnetic screen layer and oversheath, described loose sleeve pipe is wrapped at least one optical fiber, pine sleeve pipe and fiber assembly are arranged at inner sleeve inside, described inner sleeve arranged outside has tension element, and described tension element arranged outside has electro-magnetic screen layer, and the electro-magnetic screen layer arranged outside has oversheath.
Described tension element is that the high-strength tensile fiber is made.
Between described inner sleeve and loose sleeve pipe, be filled with fine cream.
Described electro-magnetic screen layer is the establishment body that the metal wire braiding forms.
The present invention has the following advantages: the present invention is provided with the tension element structure, has strengthened the tensile property of optical cable, and crooking ability also is improved, and prevents under the effect of ambient pressure, optical fiber being caused damage, and can be applicable to comparatively complicated, severe external condition.The material that uses is fibrous material, and cost is low, is conducive to increase economic efficiency.Simultaneously the present invention also is provided with electro-magnetic screen layer, has avoided light signal to be subject to the impact of electromagnetic noise, has improved the quality of communication.
