Abstract
The invention discloses an anti-bending optical cable, comprising a plurality of cable cores, a spiral steel jacket, an inner sheath, a braided layer and an outer sheath. The spiral steel jacket wraps the plurality of cable cores coaxially and uniformly. The inner sheath wraps the spiral steel jacket coaxially and uniformly. The braided layer wraps the inner sheath coaxially and uniformly. The outer sheath wraps the braided layer coaxially and uniformly. The braided layer is a stainless steel braided layer. The inner sheath layer and the outer sheath layer are made of polyethylene or polyvinyl chloride. In this way, the invention has the advantages of being novel in structure, low in loss, low in chromatic dispersion, excellent in compression resistance, good in mechanical property, excellent in bending degree, anti-aging, wear resistant, suitable for field harsh environments, stable in performance, long in service life, convenient and practical, and so forth, and has a broad market prospect in popularity of anti-bending optical cables.
Description
Technical field
The present invention relates to cable field, particularly relate to a kind of bending-resistant optical cable.
Background technology
Along with the progress of the reach of science and society, information transmission becomes a part indispensable in modern production life.
The propagation of the signal of telecommunication is it is generally required to cable or optical cable are as carrier, but existing optical cable general bending degree and abrasivity can not get both, and have certain potential safety hazard, are unfavorable for permanent use.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of bending-resistant optical cable, by adopting spiral steel bushing and braid to substantially improve the flexibility of optical cable, and adopt sheath and outer jacket to improve abrasivity, novel structure, loss is low, dispersion is low, crushing resistance is excellent, good mechanical property, aging resistance are wear-resistant, suitable in field extreme environment, stable performance, long service life, convenient and practical, bending-resistant optical cable universal on have market prospect widely.
For solving above-mentioned technical problem, the present invention provides a kind of bending-resistant optical cable, including: some cable cores, spiral steel bushing, sheath, braid and outer jacket, described spiral steel bushing is coaxially uniformly coated with described some cable cores, described sheath is coaxially uniformly coated with described spiral steel bushing, described braid is coaxially uniformly coated with described sheath, described outer jacket is coaxially uniformly coated with described braid, described braid is rustless steel braid, and the material of described sheath and described outer jacket is polyethylene or polrvinyl chloride.
In a preferred embodiment of the present invention, the thickness of described spiral steel bushing and described braid is respectively less than the thickness of described sheath.
In a preferred embodiment of the present invention, the thickness of described sheath is more than the thickness of described outer jacket.
The invention has the beneficial effects as follows: bending-resistant optical cable of the present invention has novel structure, loss is low, dispersion is low, crushing resistance is excellent, good mechanical property, flexibility are splendid, aging resistance is wear-resistant, suitable in field extreme environment, stable performance, long service life, the advantage such as convenient and practical, bending-resistant optical cable universal on have market prospect widely.
