Description
Technical field
The present invention relates to the optical cable technology field, the especially a kind of fibre ribbon and the fine compound optical cable that looses.
Background technology
Along with the development of society, the application of optical cable is increasing, yet because the restriction of machinery and equipment, in the existing optical cable, the optical cable of big core number is normally made optical fiber ribbon cable.Optical fiber ribbon cable is that some fibre ribbons are put into loose sleeve pipe, and the formation cable core then, coats protective seam outside cable core around central reinforce member is stranded with the many essentially identical loose sleeve pipes of external diameter then, and the extrusion molding restrictive coating forms outside protective seam again.Owing in the fibre ribbon some optical fiber are arranged, arranging side by side, therefore, its width is bigger, when in same loose sleeve pipe, the multifiber band being arranged, usually fibre ribbon is realized by stacked mode that under the stacked situation, the diagonal line of optical fiber ribbon body is just longer, like this, to make fibre ribbon not run into loose sleeve pipe unaffected with the optical property of guaranteeing optical fiber for work in-process, therefore, needs to strengthen the diameter of loose sleeve pipe.Therefore, external diameter with loose sleeve pipe of fibre ribbon is relatively thicker, as many loose sleeve pipes when central reinforce member is stranded, between adjacent loose sleeve pipe, can form bigger gap, in order to make optical cable can meet the permeability performance of national Specification, usually in the gap, fill a large amount of viscosity filling materials, strengthen the cost of optical cable so greatly.
In addition, under many circumstances, because the requirement of optical cable core number can cause the very big waste of optical cable cost usually.Provide the optical cable of one 156 core such as customer requirement, and normal structure is the loose sleeve pipe of 72 cores, certainly will will produces three essentially identical loose sleeve pipes of external diameter like this, wherein two is 72 core/pipes of standard, and another root is 12 core/pipes.And for the loose sleeve pipe of 12 cores/pipe, general fiber optic cable makers has stock, and is the structure of standard.Because the external diameter of the loose sleeve pipe of 72 cores/pipe is more much bigger than the external diameter of 12 cores/loose sleeve pipe of pipe, just starting material are much more, therefore, caused the very big waste of cost.
Summary of the invention
In order to address the above problem, the invention provides a kind of fibre ribbon and the fine compound optical cable that looses, it is realized by the following technical solutions:
The fibre ribbon and the fine compound optical cable that looses, it comprises at least: a banded loose sleeve pipe 1, a reinforcement 4, a protective seam 8 and a restrictive coating 9; And comprise a fibre ribbon 3 in the banded loose sleeve pipe 1 at least; The loose sleeve pipe 1 of described band shape centers on reinforcement 4 stranded and longitudinal extensions with substantially invariable pitch and specific stranded mode; Described protective seam 8 is positioned at outside the stranded banded loose sleeve pipe 1, and described restrictive coating 9 is positioned at outside the protective seam 8; It is characterized in that: in this optical cable, also comprise at least one diffusing shape pine sleeve pipe 6, comprise the shape optical fiber 7 that looses in the shape pine sleeve pipe 6 that looses; And described diffusing shape pine sleeve pipe 6 is arranged in the gap of adjacent banded loose sleeve pipe 1 and protective seam 8 formation.
Above-mentioned described stranded mode is the mode of the alternate or spiral in the left and right sides.
The radical of above-mentioned described diffusing shape optical fiber 7 is the 1-12 root.
Number of fibers in the above-mentioned described every fibre ribbon 3 is the 2-24 root.
Further, water-blocking material 2 in can also being filled with in the loose sleeve pipe 1 of above-mentioned described band shape, and water-blocking material 2 is petroleum jelly or water-proofing powder or water blocking yarn in described.
Further, also can be filled with water-blocking material in the above-mentioned described diffusing shape pine sleeve pipe 6, and described water-blocking material is petroleum jelly or water-proofing powder or water blocking yarn.
Further, can also be filled with outer water-blocking material 5 in the gap within the above-mentioned described protective seam 8, and described outer water-blocking material 5 is petroleum jelly or water-proofing powder or water blocking yarn.
The base material of above-mentioned described protective seam 8 is aluminium strip or steel band or glass fiber tape or mica tape or waterstop or polyester bundle yarn.
The material of above-mentioned described restrictive coating 9 is low density polyethylene or medium density polyethylene or high density polyethylene or low smoke and zero halogen tygon or smokeless halogen-free polyvinyl or other plastics.
Owing to adopted the loose sleeve pipe of fibre ribbon and diffusing shape Optical Fiber Composite, therefore save the cost of optical cable greatly, and shifted to an earlier date the progress of delivery, make the production of banded loose sleeve pipe also can realize standardization and the production of can getting ready the goods.
