Abstract
The utility model relates to a kind of for communicating and the self-supporting skeleton type leading-in optic cable of field of information transmission.Include optical cable and self-supporting messenger wire, optical cable and self-supporting messenger wire are connected by connecting band, it is characterized in that described optical cable is slotted core cable, described slotted core cable comprises the oversheath of skeleton and coated skeleton, circumference along skeleton offers longitudinally fine groove, longitudinally install fiber unit in fine groove, between skeleton and oversheath, be coated with waterstop, described self-supporting messenger wire is made up of reinforcement and sheath.The beneficial effects of the utility model are: 1. the utility model cable strength is high, lateral pressure resistant performance is good, 8 font self supporting structure are easy to that self-supporting is built on stilts lays, be especially suitable for use as outdoor Self-bearing-type overhead leading in cable, lay easy, the laid down cost of optical cable can be saved; 2. adopt single discrete optical fiber, and not containing ointment, be easy to any optical fiber of difference from optical cable and continue; Difference continues conveniently.
Description
Technical field
The utility model relates to a kind of for communicating and the self-supporting skeleton type leading-in optic cable of field of information transmission.
Background technology
Along with broadband implementation, fiber to the home engineering is day by day universal in city, and fiber to the home engineering construction is progressively turned to vast rural area by operator.In the fiber cable laying of rural area fiber to the home engineering, leading in cable is applied to village by electric line pole is built on stilts by usual employing, the mode that butterfly cable is registered one's residence again is built, this just requires that leading in cable can go out single or multifiber in route top set at any time and to carry out rolling off the production line the construction that continues of optical fiber, common loose jacket layer strand optical cable generally can not lay by Self-bearing-type overhead, indoor branching tight sleeve optic cable is not suitable for again in outdoor utility, and usually only need difference 1 to 2 core fibre and house lead-in optical cable welding from leading in cable when Optical Distribution Point carries out point light, pine jacket layer strand optical cable is difficult to difference simple optical fiber, and it is large to the damage of optical cable after difference, large on the impact that continues below.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists for above-mentioned prior art and proposes a kind of self-supporting skeleton type leading-in optic cable, and it is built on stilts and lay that it is not only suitable for indoor and outdoor, and is easy to optical fiber and extracts out arbitrarily from cable and carry out difference and continue.
The technical scheme that the problem that the utility model is the above-mentioned proposition of solution adopts is: include optical cable and self-supporting messenger wire, optical cable and self-supporting messenger wire are connected by connecting band, it is characterized in that described optical cable is slotted core cable, described slotted core cable comprises the oversheath of skeleton and coated skeleton, circumference along skeleton offers longitudinally fine groove, longitudinally install fiber unit in fine groove, between skeleton and oversheath, be coated with waterstop, described self-supporting messenger wire is made up of reinforcement and sheath.
By such scheme, described oversheath is linked into one by the sheath of connecting band and self-supporting messenger wire, forms 8-shaped xsect.
By such scheme, the fine groove of described longitudinal direction circumferentially arranges 3 ~ 12, and longitudinally fine groove extends twist.
By such scheme, described fiber unit is resin-coating optical fiber or tight tube fiber, and diameter range is from 0.25mm to 1mm.
By such scheme, in the fine groove of each longitudinal direction, be laid with 1 ~ 12 fiber unit.
By such scheme, described frame center is installed on central reinforce member.
By such scheme, described waterstop is coated with metal tape.
By such scheme, the reinforcement of described self-supporting messenger wire is metal wire rope or nonmetal round bar.
The beneficial effects of the utility model are: 1, the utility model cable strength is high, lateral pressure resistant performance is good, 8 font self supporting structure are easy to that self-supporting is built on stilts lays, be especially suitable for use as outdoor Self-bearing-type overhead leading in cable, lay easy, the laid down cost of optical cable can be saved; 2, adopt single discrete optical fiber, and not containing ointment, be easy to any optical fiber of difference from optical cable and continue; Difference continues conveniently.
Accompanying drawing explanation
The radial structure sectional view of Fig. 1 the utility model embodiment.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Include optical cable and self-supporting messenger wire, optical cable and self-supporting messenger wire are connected by connecting band, described optical cable is slotted core cable, described slotted core cable comprises the oversheath 2 of skeleton 5 and coated skeleton, circumference along skeleton offers longitudinally fine groove 4, longitudinally fine groove circumferentially arranges 6, and longitudinally fine groove extends twist, longitudinally fine slot cross-section takes the shape of the letter U, 4 tight tube fibers are laid with in each groove, described frame center is installed on central reinforce member 8, in order to identify the fiber unit in different fine groove, is provided with the tag line 3 of the fine groove order of mark on skeleton 5 surface.Skeleton distinguishes coated waterstop 6 and metal tape 7 outward, and outermost layer is oversheath 2.Described self-supporting messenger wire is made up of reinforcement 1 and sheath, and reinforcement is wire rope.Described oversheath is linked into one by connecting band 10 and the sheath of self-supporting messenger wire, forms 8-shaped xsect.
