Utility model content
For the deficiency existing in prior art, the utility model provides a kind of improves restrictive coating post shrinkage, increase optical cable lateral pressure resistant performance, be beneficial to the embedded sheath beam tube type air-blowing minisize optical cable of protecting loose sleeve pipe inner fiber, improving optical cable air-blowing performance.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of embedded sheath beam tube type air-blowing minisize optical cable, comprise optical fiber, optical fiber is coated loose sleeve pipe and restrictive coating outward successively, the fine cream of uniform filling in pine sleeve pipe, optical fiber described in it is positioned at pine cover tube hub, between pine sleeve pipe and restrictive coating, assistant reinforcement part is set, between assistant reinforcement part and restrictive coating, arranges and tear rope, some being parallel to each other and symmetrical non-metal reinforcement member is set in described restrictive coating.Non-metal reinforcement member add the contraction that has limited restrictive coating, and then make loose sleeve pipe inner fiber remaining long stable, improve the temperature performance of optical cable.
Above-mentioned a kind of embedded sheath beam tube type air-blowing minisize optical cable, the non-metal reinforcement member described in it is nonmetal rigidity reinforcement.Its quantity can require to arrange some according to the tensile property of optical cable.
Above-mentioned a kind of embedded sheath beam tube type air-blowing minisize optical cable, the Edge Distance restrictive coating outward flange distance of the non-metal reinforcement member described in it is 0.1-0.8mm, apart from assistant reinforcement part Edge Distance, is less than or equal to 0.5mm.
Above-mentioned a kind of embedded sheath beam tube type air-blowing minisize optical cable, the optical fiber described in it is one group of optical fiber or fibre ribbon.
Above-mentioned a kind of embedded sheath beam tube type air-blowing minisize optical cable, the fiber number described in it is 1-48 core.
Beneficial effect:
The utility model is embedded into non-metal reinforcement member in restrictive coating, and the retraction of restrictive coating is played to certain restriction, has stablized the excess fiber length in loose sleeve pipe, has improved the temperature performance of optical cable; The restrictive coating thickness increasing, has increased the lateral pressure resistant performance of optical cable, is beneficial to the optical fiber in the loose sleeve pipe of protection; That when meeting cable machinery performance, the diameter of loose sleeve pipe can be done is less, thereby reduces the diameter of optical cable, improves the air-blowing performance of optical cable.
