Abstract
The utility model discloses an 8-shaped central-beam-tube optical cable. The 8-shaped central-beam-tube optical cable comprises an optical cable main body and a steel stranded wire, wherein the steel stranded wire extends axially along the optical cable main body; the optical cable main body and the steel stranded wire are integrally covered by an 8-shaped polyethylene outer sheath; the optical cable main body is internally provided with optical fiber; the outer surface of the polyethylene outer sheath is provided with marking lines for indicating the affiliation of the optical cables; and the marking lines indicate the optical cables with different affiliations by the line shapes instead of color change. Therefore, the appearance of the marking lines can not change along with the increase of the used ages, and when multiple cables are laid simultaneously, all the optical cables are easily distinguished and differentiated still after long-term use, so that the installation, the maintenance and the detection are very convenient.
Description
Technical field
The utility model relates to a kind of product that is used for the optical communication transmission field, is specifically related to a kind of built on stilts " 8 " font central beam pipe optical cable that lays that is applicable to.
Background technology
In the prior art,, high tensile strength can be provided, be convenient to built on stilts laying because " 8 " font optical cable uses the High Strength Steel twisted wire as from fixed bearing element; Simultaneously messenger wire is integrated with optical cable, once constructs and can accomplish, and avoided the buying respectively of traditional messenger wire and optical cable and lay, thereby the buying installation cost of " 8 " font optical cable and the engineering cycle of laying reduces greatly.
Because mostly the profile of optical cable is same color, when many " 8 " font optical cables lay, just have the deficiency that is difficult for identification on same circuit, cause installation, maintenance, detection all inconvenient; The solution of tional identification mode is to adopt the vitta recognition technology; But along with the optical cable increase of tenure of use, bigger variation can appear in the vitta color, and produces than big-difference with original color; After causing many optical cables to lay simultaneously, the technological deficiency that is difficult to differentiate usually appears.
Summary of the invention
For overcoming the defective of above-mentioned prior art, the utility model technical matters to be solved is intended to provide a kind of " 8 " font central beam pipe optical cable, so that the optical cable after long-term the use still can very conveniently be differentiated.
For solving the problems of the technologies described above; The utility model proposes a kind of " 8 " font central beam pipe optical cable; Comprise the optical cable main body and prolong the axially extended steel strand wires of said optical cable main body; Said optical cable main body and steel strand wires coat through " 8 " font tygon oversheath one, in the said optical cable main body optical fiber are set, and the outside surface of said tygon oversheath is provided with the sign line that is used to indicate the optical cable ownership.
Further, said sign line is through the ownership of lines shape variation indication optical cable.
Said sign line can be arranged to two, is separately positioned on the two ends up and down of " 8 " font tygon oversheath.
Particularly, said optical cable main body is respectively from inside to outside: the loose sleeve pipe, aramid yarn, tygon inner sheath of optical fiber, parcel optical fiber, protect and tear rope, waterstop, aluminium strip outward.Around said optical fiber, can also be filled with fine ointment; Protect in said aramid yarn, being provided with and tear rope.
After adopting said structure,, thereby the tension force bearing part of optical cable and optical cable main body are kept apart owing to the optical cable main body is supported by superposed steel strand wires; Under cable body vacant state, each fiber unit in the optical cable main body receives any pulling force longitudinally hardly, and the utility model can keep whole advantages of tradition " 8 " font optical cable like this: cable outer diameter is little, the engineering laid down cost is low; Construction period is short, simultaneously, because cable outer sheath is provided with the sign line of special indication optical cable ownership; And should indicate line with its shape, but not color indicates the optical cable of different ownership, like this; The outward appearance that indicates line can not change along with the increase of tenure of use; When many cables laid simultaneously, each optical cable of use back still was easy to differentiate, distinguish for a long time, installation, maintenance, very convenient when detecting.
Below through combining specific embodiment and accompanying drawing that the technical scheme of the utility model is carried out comparatively detailed description.
Description of drawings
Fig. 1 is the cross-sectional structure synoptic diagram of the utility model described " 8 " font central beam pipe optical cable.
Among the figure, protect in 1 optical fiber, 2 fine ointment, 3 loose sleeve pipes, 4 aramid yarns, 5 to tear to protect outside rope, the 6 tygon inner sheaths, 7 and tear rope, 8 waterstops, 9 aluminium strips, 10 steel strand wires, 11 tygon oversheaths, 12 sign lines.
Embodiment
With reference to Fig. 1, the utility model described " 8 " font central beam pipe optical cable comprises the optical cable main body, and this optical cable main body is respectively the optical fiber 1 that transmission signals is used from inside to outside; The loose sleeve pipe 3 of parcel and protection optical fiber; Be positioned at said loose outside of sleeve, be used to strengthen the aramid yarn 4 of optical cable pulling strengrth; Be used to protect the tygon inner sheath 6 of loose sleeve pipe 3; Outer the protecting that is used to out stripping tygon oversheath torn rope 7; Be used for waterstop 8 aluminium strip 9 moistureproof that optical cable vertically blocks water with being used for optical cable.
In around the said optical fiber 1, can also be filled with the fine ointment 2 that stops moisture to contact with optical fiber; Between said aramid yarn 4 and tygon inner sheath 6, also be provided be used to out stripping tygon inner sheath in protect and tear rope 5.
For ease of Overhead suspension wire; The utility model is on aforementioned optical cable main body; Prolong said optical cable body shaft to being extended with the High Strength Steel twisted wire that can bear the optical cable longitudinal pulling force, said steel strand wires coat through " 8 " font tygon oversheath one and form " 8 " font central beam pipe optical cable.
The key distinction of the utility model described " 8 " font central beam pipe optical cable and prior art just is: the outside surface of above-mentioned tygon oversheath is provided with the sign line that is used to indicate the optical cable ownership; This sign line can form through extruding in the manufacturing process of oversheath; For different optical cables; This shape that indicates line can be different fully, even can make according to user's specific requirement; On the other hand, this sign line can be arranged to two, is separately positioned on the two ends up and down of " 8 " font tygon oversheath, and is as shown in Figure 1.
Adopt the utility model, because the setting of High Strength Steel twisted wire makes optical cable can bear bigger pulling force than ordinary optical cable on the one hand; Avoided traditional aerial optical cable must lay earlier the Installation Modes of messenger wire in addition, reduced greatly and lay difficulty, on the other hand; Through indicating the setting of line; And the difformity that respectively indicates line carries out special marking to optical cable, changes traditional optical cable and indicates the optical cables of different ownership through the variation that indicates line color, like this; The outward appearance that indicates line can or not be difficult for changing along with the increase of tenure of use; When many cables laid simultaneously, each optical cable after the use still was easy to resolution, difference for a long time, and is very convenient when therefore installation, maintenance, detection.
