Abstract
The utility model discloses an FTTH (Fiber to the Home) self-supporting armored butterfly-shaped leading-in optic cable which comprises an optic cable. A metal armored layer is arranged on the outer side of the optic cable and wound around an optical fiber, a sheath is arranged at the periphery of the metal armored layer, reinforcing pieces are arranged in the sheath and is axially parallel to the metal armored layer, and a suspension wire is arranged at the outer side of the sheath and is parallel to and fixedly connected with the sheath. The characteristics of a structure of the FTTH self-supporting armored butterfly-shaped leading-in optic cable assists in improving the lateral pressure resistance of the optical fiber; even under the certain lateral pressure, the whole optical fiber is just bent about a little of uniform radian under the action of the supporting forces of the linear reinforcing pieces and has the certain instantaneous impaction resistance; in addition, the metal suspension wire is fixedly connected with the outer part of the sheath, so that the lateral pressure resistance and the instantaneous impaction resistance of the optical fiber are reinforced.
Description
Technical field
The utility model relates to a kind of communications optical cable.
Background technology
The optical fiber of China is registered one's residence and is in the starting stage now; But optical fibre frame is located in the open-air atmosphere, especially in the outdoor environment in mountain area, suffers that through regular meeting grabbing of some animals such as mouse sting and seek connections with; And other external force moment impacts that occur easily in environment out of doors; Optical fiber is bitten broken or long-time load-bearing and instant impact effect meeting cause fibercuts, causes fiber transmission attenuation to increase or transmission is interrupted, and repairing can consume a large amount of maintenance costs again then.
The utility model content
The technical matters that the present invention will solve provides and a kind ofly can prevent effectively that animal from grabbing and sting and certain lateral pressure resistant performance and communications optical cable with certain opposing moment external impacts performance.
For solving the problems of the technologies described above; The utility model has adopted following technical scheme: FTTH self-bearing type armouring butterfly leading in cable; Comprise optical fiber, be provided with the metal armouring layer of wrapped optical fiber in outer fiber, metal armouring layer periphery is provided with sheath; Sheath inside also is provided with the reinforcement with metal armouring layer axially parallel, and the sheath outside is provided with messenger wire parallel with sheath and that be fixedly connected.Said sheath xsect is butterfly, and processing mode is an extrusion moulding, and said messenger wire can be a metal material, also can be other stretch-resistance such as high-intensity fiber made preferably, is fixed on the side of sheath.Such structure makes optical fiber avoid that external force is directly impacted and animal grabs and stings, and can possess the performance of certain lateral pressure resistant power and anti-instant impact again.
As a kind of improvement, said optical fiber is located at the center of sheath, helps optical fiber to obtain best protection, the preferred bend-insensitive optical fiber of the type of said optical fiber.
As a kind of improvement; Said reinforcement is provided with at least two and be symmetrically distributed in the both sides of optical fiber; Reinforcement can improve the stretch-proof performance of whole piece optical cable, and optical cable when the load-bearing constant weight, can reduce the optical cable degree of crook under self gravitation like this; And keep evenly crooked, protection optical fiber is not by jackknifing or disconnection.
As a kind of improvement, said sheath cross sectional dimensions is 2.0mm * 3.0mm.
As a kind of improvement, two offsides of said sheath are provided with the fine tearing port of getting that is easy to tear, and the line of two tearing ports passes the metal armouring layer, the optical fiber of more convenient like this maintenance optical cable segment fault.
The utility model is a FTTH self-bearing type armouring butterfly leading in cable, promptly is surrounded with the metal armouring layer in outer fiber, and the metal armouring layer can prevent effectively that animals such as mouse from grabbing and sting the destruction that optical fiber is caused; Metal armouring layer periphery is provided with the sheath that xsect is the butterfly extrusion moulding; Also be provided with reinforcement in the sheath with metal armouring layer axially parallel; Other is provided with one or several messenger wire is parallel with sheath and be fixedly connected, and helps optical cable to improve the performance of lateral pressure resistant power, even under certain wall pressure; The whole piece optical cable also can be that the evenly bending of radian takes place in a small amount at the holding power of reinforcement on; And the effect of certain anti-instant impact is arranged, and messenger wire and sheath outside are affixed, have then further strengthened the performance of optical cable lateral pressure resistant power and instant impact.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
The structural representation of a kind of embodiment of the utility model as shown in Figure 1, FTTH self-bearing type armouring butterfly leading in cable comprises optical fiber 2, is surrounded with metal armouring layer 1 in outer fiber, as optical fiber penetralia protective seam, in order to baiting of protection mouse and other animals; Metal armouring layer periphery is provided with sheath 4, is used to strengthen the flexible protective seam of optical cable as optical fiber, and the xsect of said sheath is butterfly and extrusion moulding; Sheath inside also is provided with the reinforcement 3 with metal armouring layer axially parallel; The sheath outside is provided with messenger wire 5 parallel with sheath and that be fixedly connected; Messenger wire can be a metal material; Also can high-intensity fiber etc. other stretch-resistance material preferably, reinforcement and messenger wire effectively help optical cable to improve the lateral pressure resistant power of self and the performance of anti-instant impact; Optical fiber 2 is positioned at the centre of sheath, and with the optimized protection of protective seam around effectively obtaining, the type of optical fiber 2 can be bend-insensitive optical fiber, also makes this optical cable more be applicable to complicated outdoor environment; Reinforcement 3 is provided with at least two and be symmetrically distributed in the both sides of optical fiber, has further improved the homogeneity of optical cable suppleness performance, can increase optical cable self serviceable life; Said sheath cross sectional dimensions is 2.0mm * 3.0mm; Two offsides of sheath are provided with the fine tearing port 6 of getting that is easy to tear; Two lines of getting fine tearing port 6 pass the metal armouring layer, when need tear the metal armouring layer of sheath taking-up parcel optical fiber, only need along two side-draws fibre tearing port line direction firmly; Sheath will be torn more easily, the fibre work of getting during convenient the maintenance.
Except that above-mentioned preferred embodiment; The utility model also has other embodiment; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
