Abstract
The utility model discloses a central beam tube optical cable comprising a plurality of optical fibers located in the central end, wherein a loose sleeve is arranged outside the optical fibers, a water blocking layer is arranged outside the loose sleeve, a composite layer is arranged outside the water blocking layer, a sheath layer is arranged outside the composite layer, and the sheath layer is internally provided with reinforcement members which are mutually symmetrical and are arranged in parallel. The central beam tube optical cable has the beneficial effects of impact resistance, tensile property, waterproof performance, small cable diameter and the like.
Description
Technical field
The utility model relates to a kind of optical cable, and particularly a kind of have shock resistance and a little central-beam tube type fiber optic cable of tensile property, water resistance and diameter.
Background technology
Optical cable is widely used in the industries such as post and telecommunications, communication, military affairs, railway, satellite, radio and television as the carrier of optical-fibre communications, it has according to textural classification: central beam formula, layer-twisted type and skeleton, and because central-beam tube type fiber optic cable has the advantages such as diameter is little, quality is light, it can take full advantage of again the strong point of conduit resource, and when at two sections optical cable weldings, can disposablely open stripping and embody convenience when laying with quick, therefore deeply be subjected to user's favor.But, optical cable is as a kind of wire that is applied in the signal transmission in the various industries, it has higher requirement, as prevent and resist the impact of external force and stretching etc. and damage performance, the performances such as waterproof, reduce simultaneously the use of protective materials, thereby reduce the length of the minimizing dish tool coiling of whole optic cable diameter, save transportation and warehouse cost.But just wherein a part of problem that solves in the prior art, to solve be to need those skilled in the art to attempt and how it is concentrated.
The utility model content
The purpose of this utility model is to provide a kind of have shock resistance and the little central-beam tube type fiber optic cable of tensile property, water resistance and optic cable diameter.
In order to solve problem set forth above, the utility model adopts following technical scheme: a kind of central-beam tube type fiber optic cable, comprise the some optical fiber that are positioned at center-side, described optical fiber is provided with loose pipe box outward, described loose pipe box is provided with water blocking layer outward, described water blocking layer is provided with composite bed outward, and described composite bed is provided with restrictive coating outward, is provided with in the described restrictive coating symmetrically and the reinforcement that be arranged in parallel.
Central-beam tube type fiber optic cable of the present utility model, preferred, described optical fiber is the UV curing optical fiber, uniform factice for filling between several optical fiber.
Central-beam tube type fiber optic cable of the present utility model, preferred, the minor increment at the edge of described reinforcement and the edge of restrictive coating is 1mm.
Central-beam tube type fiber optic cable of the present utility model, preferred, described composite bed is plastic-steel material.
Central-beam tube type fiber optic cable of the present utility model, preferred, described loose pipe box is the PBT material.
Central-beam tube type fiber optic cable of the present utility model, preferred, described water blocking layer is waterproof paste.
