Abstract
The utility model relates to a 8-shaped optical cable with a three-unit structure for the field of optical communication. The 8-shaped optical cable comprises an external reinforcing piece, wherein the external reinforcing piece is connected with the optical cable by a hanging strip, and the optical cable comprises a plurality of cable cores and an outer sheath. The 8-shaped optical cable is characterized in that the cable cores are formed by stranding three communication units or a plurality of communication units and filling units with the total number of three. The 8-shaped optical cable has the beneficial effects that 1, the optical cable adopts a 8-shaped structure and a layer stranded fiber optic cable, thereby being simple in structure, multiple in optical cable cores, good in technological efficiency, low in production cost, and suitable for fiber to the home (FTTH); 2, the optical cable adopts a three-unit layer stranded structure, so that the diameter of the optical cable is reduced, the structure of the optical cable is simplified, the structural miniaturization of the optical cable can be preferably performed, the strength of the optical cable is enhanced, and the paving of the optical cable is convenient; and 3, the optical cable adopts a semi-dry structure, and the cable cores are free of factice, so that the environment pollution can be avoided, and the construction is convenient.
Description
Technical field
The utility model relates to a kind of three cellular constructions, 8 font optical cables that are used for optical communication field.
Background technology
There is multiple different structure in existing optical cable for optical fiber to house, and wherein 8 font optical cables are owing to there is hanging piece reinforcing element load, and it is built on stilts to be directly used in little span self-bearing type, is convenient to introduce sub-district and building, therefore uses very general in optical cable for optical fiber to house.But existing 8 font optical cables mostly are central beam tube type structure or Unit 5 and above layer-twisted type structure, and the fiber number that the central beam tube type structure comprises is few, often can not satisfy user's demand; The cable configuration relative complex of Unit 5 and above layer-twisted type structure, the manufacture process requirement height, manufacturing cost is also higher, and construction is used convenient inadequately.
Summary of the invention
Technical problem to be solved in the utility model is the problem that exists at above-mentioned prior art and provides a kind of contained fiber number many that simple in structure, low cost of manufacture is convenient to three cellular constructions, the 8 font optical cables that lay and use.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is:
Include outer reinforcement, outer reinforcement links to each other with optical cable by suspender belt, described optical cable comprises cable core and oversheath, and its difference is that described cable core constitutes by three communication units are mutually stranded, perhaps adds up to three communication unit by addition and forms with filler cells is mutually stranded.
Press such scheme, described outer reinforcement coats sheath outward, and sheath is connected as a body by suspender belt and cable outer sheath.
Press such scheme, include water-blocking component in the described cable core, constitute the half dry type cable configuration.
Press such scheme, described communication unit comprises loose sleeve pipe and fiber unit, and fiber unit places loose sleeve pipe, and described fiber unit is one or more in optical fiber, fibre bundle, the fibre ribbon.
Press such scheme, described outer reinforcement is metal outer reinforcement or nonmetal outer reinforcement.
The beneficial effects of the utility model are: 1, adopt 8 font structures and layer-stranding cable, not only simple in structure, fiber number is many, and good manufacturability, and production cost is low, is applicable to that Fiber to the home; 2, optical cable adopts three unit layer-twisted type structures, has dwindled the diameter of optical cable, has simplified cable configuration, helps the miniaturization of cable configuration, has also strengthened the intensity of optical cable simultaneously, and has been convenient to lay; 3, half dry type structure, cable core does not have ointment, can not cause environmental pollution, is convenient to construction.

Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
First embodiment of the present utility model as shown in Figure 1, it includes an outer reinforcement 2 that coats sheath 1, outer reinforcement is metal outer reinforcement or nonmetal outer reinforcement, the metal outer reinforcement is steel wire, copper wire or signal wire; Nonmetal outer reinforcement is that glass fibre strengthens rod or aramid fiber strengthens rod, and outer reinforcement is embedded in the sheath, the main load-bearing component of conduct when optical cable is stressed.Outer reinforcement links to each other with optical cable by suspender belt 3, and constituting radial section is the cable configuration of 8 fonts, and described optical cable comprises cable core and oversheath 8, and outer reinforcement and sheath are connected as a body by suspender belt and cable outer sheath.Described cable core constitutes by three communication units are mutually stranded, perhaps by a communication unit and two filler cells, 7 mutually stranded forming.Described communication unit comprises loose sleeve pipe 6 and fiber unit 5, and fiber unit places loose sleeve pipe, and described fiber unit is optical fiber, fibre bundle or fibre ribbon.Described filler cells can be the round section gasket for packing or has the plain conductor of sheath.Also be filled with water-blocking component 4 in the cable core, water-blocking component can be water blocking yarn, water-proofing powder, waterproofing rope or waterstop and other solid-state material water-proof material.
Second embodiment of the present utility model as shown in Figure 2, it is to be provided with a central reinforce member 9 with the difference of a last embodiment in mutually stranded communication unit, perhaps in mutually stranded communication unit and filler cells, be provided with a central reinforce member 9, in order to the stability of further enhancing cable configuration, thus the mechanical property and the environmental performance index of raising optical cable.
Claims (6)
1. cellular construction 8 font optical cables, include outer reinforcement, outer reinforcement links to each other with optical cable by suspender belt, described optical cable comprises cable core and oversheath, it is characterized in that described cable core constitutes by three communication units are mutually stranded, perhaps add up to three communication unit and form with filler cells is mutually stranded by addition.
