Abstract
The utility model relates to an armored bow-type optical cable for access network, which is characterized in that the integral cross section of the optical cable is butterfly-shaped, the armored bow-type optical cable comprises a colored optical fiber in the center, a protective jacket arranged on the periphery of the optical fiber through extrusion molding, and reinforcing parts arranged in the protective jacket and on both sides of the optical fiber, a metal armoring layer is lapped on the optical fiber, the protective jacket wraps the periphery of the metal armoring layer; as the metal armoring layer is lapped on the periphery of the optical fiber of the bow-type optical cable, the optical fiber has better side pressure and external impact resistance, better mechanical strength, also has rat-biting protection function, and is applicable to indoor and outdoor laying and has stronger practicality.
Description
Technical field
The utility model relates to a kind of communications optical cable, relates in particular to a kind of indoor butterfly optical cable.
Background technology
Butterfly optical cable is because its shape of cross section is the shape of butterfly, so be called butterfly optical cable.Butterfly optical cable is widely used in Fiber to the home with FTTH as light connecting line and outdoor smooth connecting line.Existing butterfly optical cable as shown in Figure 1, it comprises the optical fiber 10 that is positioned at the center, be coated on outer PVC sheath 20 of optical fiber 10 and metal or the non-metal reinforcement member 30 that is arranged on sheath 20 and is positioned at optical fiber 10 both sides, this kind optical cable is when running into external impacts, external force will act directly on the optical fiber 10, cause optical fiber disconnected fine bigger than normal easily with decay, and indoor lay the back find its often stung by mouse bad, thereby influence the normal transmission of signal, cause signal interruption.
The utility model content
The utility model purpose is that a kind of butterfly optical cable that effectively prevents external impacts and mouse bite preventing is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Access Network armouring butterfly optical cable, its whole xsect is butterfly, comprise the colored optical fiber that is positioned at the center, extrusion molding at the sheath of described optical fiber periphery, be arranged on sheath and be positioned at the reinforcement of optical fiber both sides, described optical fiber is surrounded with the metal armouring layer, and described sheath is coated on described metal armouring layer periphery.
The number of described optical fiber is 2～12.
In optimizing a kind of mode of implementing, described optical fiber is 2, and optical cable is of a size of 3.0 * 2.0mm.
Described reinforcement is the FRP reinforcement.
Described sheath is a low-smoke halogen-free flame-retardant sheath.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the utility model butterfly optical cable is because at the wrapped metal armouring layer of optical fiber periphery, thereby make optical fiber have anti-preferably side pressure and external impacts ability, physical strength is better, simultaneously, it also has the function of mouse bite preventing, can be used for indoor and outdoors simultaneously and lay, and has bigger practicality.
Description of drawings
Accompanying drawing 1 is the viewgraph of cross-section of a kind of butterfly optical cable in the prior art;
Accompanying drawing 2 be the utility model the viewgraph of cross-section of concrete a kind of butterfly optical cable of implementing;
Wherein: 1, optical fiber; 2, sheath; 3, reinforcement; 4, metal armouring layer; 10, optical fiber; 20, sheath; 30, reinforcement;
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
Butterfly optical cable as shown in Figure 2, comprise the colored optical fiber 1 that is positioned at the center, wrapped outside optical fiber 1 metal armouring layer 4, be coated on the low-smoke halogen-free flame-retardant sheath 2 of metal armouring layer 4 periphery, sheath 2 is provided with the recess that is easy to peel off at optical fiber 1 position upper and lower sides, thereby make the xsect of whole optical cable be butterfly-like, add man-hour, go out described sheath by the mould extrusion molding that is complementary with sheath 2 shapes.The both sides that are positioned at optical fiber 1 in sheath 2 also are provided with reinforcement 3, and this reinforcement can be metal reinforcement, also can select non-metal reinforcement member for use, as FRP material reinforcement, thereby make that the optical cable weight of making is lighter.
The number of fibers of butterfly optical cable can be provided with different radicals according to the needs of concrete environment for use, generally can be 2～12, and correspondingly, the size of sheath 2 is also and then done corresponding the adjustment.In the present embodiment, the radical of optical fiber 1 is 2, and the cross sectional dimensions of optical cable is 3.0 * 2.0mm.
The utility model optical cable has following advantage:
(1) in light weight, fiber cable laying is convenient, has well anti-mouse to sting function after optical fiber adopts armouring wrapped all around.
(2) well anti-side pressure and external impacts ability are arranged, mechanical strength is better.
(3) product processing technique is simple, the yield rate height.
(4) product can be used for outdoor and indoor laying simultaneously.
Claims (5)
