Abstract
The utility model relates to self-supporting optical cable used for overhead laying, which is particularly suitable to be used in fiber to the home (FTTH) network transmission, comprising a support part connected with the optical cable in parallel via a hanging belt. An outer sheath of the optical cable, in a straight and extended state, is connected with the support part, and the optical fiber laid inside a casing of the outer sheath leaves an excess length from 0.1% to 0.4% of the whole length. The beneficial effects of the utility mode are that: 1. the optical cable is connected with the support part as one body and is laid overhead outdoors, which is convenient for the installation and operation, and when the optical cable is separated from the support part, the optical cable can directly enter the house as indoor optical cable and is laid indoors, which is simple and convenient in transfer; 2. the outer sheath of the optical cable and the casing and so on are connected with the support part in the straight and extended state; the optical fiber has the excess length, which not only facilitates production, but also saves materials and ensures good shape and more reasonable structure establishment. Meanwhile, the optical fiber in the optical cable laid overhead can also be protected against the effect of the external force and tension, thus maintaining good communication and transmission performance of the optical fiber.
Description
Technical field
The utility model relates to a kind of built on stilts self-support cable that lays that is used for, and this optical cable is particularly suitable for using in the fiber-to-the-home Network Transmission.
Background technology
Along with development of Communication Technique, the application of optical cable is increasingly extensive.The system of laying of optical cable includes pipeline, direct-burried and built on stilts laying.Along with optical fiber in the Access Network extends gradually to user side, Fiber to the home, and network is developed rapidly, and the optical fiber cable demand that adapts with it also increases rapidly.Because this class optical cable transmission range is shorter,, adopt built on stilts method of laying usually for ease of installing and inserting.In the prior art, when making somebody a mere figurehead laying optical cable, mostly adopt discrete supporting member to hang the mode of optical cable, this has brought inconvenience to laying installation; For addressing the above problem, developed a kind of incorporate self-support cable, it is linked into one by supporting member, connection suspender belt and optical cable and constitutes, for avoiding optic fibre force in the built on stilts optical cable of installing, connecting band is arranged to discontinuous, and the optical cable between every section connecting band stays certain crooked surplus length, though this brings convenience to laying installation, but the comparatively trouble of make, and consumptive material comparatively.
Summary of the invention
Technical problem to be solved in the utility model be the deficiency that exists at above-mentioned prior art and provide a kind of not only simple for production, consumptive material is few, and laying installation self-support cable easily.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: include supporting member, supporting member is by connecting suspender belt and being connected to optical cable, its difference is that the oversheath of described optical cable is to stretch and extends shape and supporting member joins that the optical fiber that is laid in the oversheath inner sleeve leaves 0.1%～0.4% surplus length.
Press such scheme, described optical cable, connection suspender belt and supporting member are connected as a body.
The beneficial effects of the utility model are: 1, optical cable and supporting member are connected as a body, and outdoor built on stilts laying, installation is convenient, and after optical cable and supporting member were separated, optical cable directly in the inlet chamber, as inside cable, laid indoor, changes simple and convenient; 2, cable outer sheath and sleeve pipe etc. join with straight configuration and supporting member, and optical fiber leaves surplus length, so not only be convenient to make, and province's material, good looking appearance, the structure setting is more reasonable, and can make optical fiber in the built on stilts optical cable that lays avoid the effect of external force and tension force equally, keeps its excellent communications transmission performance.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of an embodiment of the utility model.
Fig. 2 cuts open figure for the lateral cross section of an embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include a supporting member 1, supporting member can coat sheath 4 by steel wire 5 or other tinsel outside and constitute, steel wire or other tinsel can be sub-thread or strands forms, supporting member also can adopt nonmetallic materials such as nylon fiber, FRP coats sheath and constitutes, the downside of sheath be connected suspender belt 2 and link to each other, the lower end that connects suspender belt is connected with an optical cable 3, the parallel extension arranged side by side of optical cable with supporting member, connecting suspender belt 2 is to connect shape continuously, or for being interrupted equi-spaced apart connection shape, optical cable is conventional cable configuration, includes oversheath 6 and sleeve pipe 7, lays the optical fiber 8 that leaves length surplus in the of 0.2% in the sleeve pipe, promptly than sleeve pipe overlength 0.2%, also can install water-blocking component 9 in the sleeve pipe, water-blocking component can be made of waterstop or water blocking yarn, oversheath 6 be connected suspender belt 2, supporting member sheath 4 is connected as a body, by fire proofing such as Polyvinylchloride (PVC), low-smoke halogen-free polyolefin (LSZH) is made, so that possess stronger fire resistance after in the optical cable inlet chamber.
Claims (6)
1, a kind of self-support cable, include supporting member, supporting member is by connecting suspender belt and being connected to optical cable, and the oversheath that it is characterized in that described optical cable is to stretch and extends shape and supporting member joins, and the optical fiber that is laid in the oversheath inner sleeve leaves 0.1%～0.4% surplus length.
2,, it is characterized in that optical cable, connection suspender belt and supporting member are connected as a body by the described self-support cable of claim 1.
3, by claim 1 or 2 described self-support cables, it is characterized in that supporting member can coat sheath (4) by steel wire (5) or other tinsel outside and constitute, steel wire or other tinsel are that sub-thread or strands form.
4, by the described self-support cable of claim 3, the downside that it is characterized in that sheath be connected suspender belt (2) and link to each other, the lower end that connects suspender belt is connected the parallel extension arranged side by side with supporting member of optical cable with an optical cable (3), connecting suspender belt (2) is to connect shape continuously, or connects shape for being interrupted equi-spaced apart.
5, by claim 1 or 2 described self-support cables, it is characterized in that optical cable includes oversheath (6) and sleeve pipe (7), lay the optical fiber (8) that leaves length surplus in the of 0.2% in the sleeve pipe, also install water-blocking component (9) in the sleeve pipe.
