Abstract
The utility model relates to a ratproof indoor and outdoor optical cable, which includes a butterfly-shaped optical cable body with a butterfly-shaped end surface. The butterfly-shaped optical cable body comprises an optical cable at the center, an LSOH (low smoke zero halogen) fire-resistant jacket coating the optical cable, and reinforcements arranged in the jacket and on two sides of the optical cable; and the butterfly-shaped optical cable body is coated with an armor layer, an aramid fiber reinforcing layer and an LSOH fire-resistant outer protection layer sequentially. In essence, the utility model relates to an improvement on the existing indoor butterfly-shaped optical cable, and endows the improved optical cable with the ratproof function through coating the butterfly-shaped optical cable body with the armor layer, the aramid fiber reinforcing layer and the extrusion-molded outer jacket; and meanwhile, the optical cable is less susceptible to the impact caused by force, and the whole optical cable has the capability of resisting side pressure and resisting stretching, so that the ratproof indoor and outdoor optical cable can be applied inside and outside rooms.
Description
Technical field
The utility model relates to a kind of communications optical cable.
Background technology
Existing butterfly optical cable mainly by optical fiber, optical fibre packages overlayed on sheath wherein and is provided with in the sheath and the metal or the non-metal reinforcement member that are positioned at the optical fiber both sides formed, the sheath extrusion molding is butterfly-shaped, thereby is easy to optical fiber ablation is come.This kind butterfly optical cable is mainly used in the indoor equipment intraconnections and connects, but in use, the discovery butterfly optical cable is broken by the teeth by mouse easily, simultaneously, optical cable is when running into external impacts, and power acts directly on the optical fiber, cause disconnected fibre and signal attenuation easily, thereby influence communication quality.
The utility model content
The utility model purpose is the optical cable that a kind of protection against rodents, anti-side pressure and stretch-proof are 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 protection against rodents indoor and outdoor optical cable, comprise that end face is the butterfly optical cable body of butterfly, described butterfly optical cable body by the optical fiber that is positioned at the center, be coated on the outer low-smoke halogen-free flame-retardant sheath of optical fiber and the reinforcement that is arranged on sheath and is positioned at the optical fiber both sides is formed, also be coated with armor, aramid fiber enhancement Layer and low-smoke non-halogen flame-retardant outer jacket successively in described butterfly optical cable body periphery.
Further, between described butterfly optical cable body and armor, also be provided with many water blocking yarns.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the utility model comes down to the improvement to the butterfly optical cable of existing indoor use, by oversheath on this external wrapped armor of butterfly optical cable, aramid fiber enhancement Layer and extrusion molding, thereby make the optical cable after improving have the mouse bite preventing function, simultaneously, optical fiber is not vulnerable to the impact of power, and whole optical cable has anti-side pressure and stretch-proof ability, not only can be applicable to indoorly, also can be applicable to outdoor environment.
Description of drawings
Accompanying drawing 1 is the viewgraph of cross-section of the utility model optical cable;
Wherein: 1, butterfly cable core; 11, optical fiber; 12, sheath; 13, reinforcement; 2, armor; 3, aramid fiber enhancement Layer; 4, outer jacket; 5, water blocking yarn;
Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is described in detail:
Optical cable as shown in Figure 1, comprise butterfly optical cable body 1, be coated on the protective jacket outside the optical cable body 1, wherein, butterfly optical cable body 1 is as cable core, it mainly is the low-smoke halogen-free flame-retardant sheath 12 of butterfly by two optical fiber 11, extrusion moldings being arranged in the center and the metal or the non-metal reinforcement member 13 that are arranged on sheath 12 and are positioned at optical fiber 11 both sides are formed, in the present embodiment, reinforcement 13 can be selected the FRP non-metal reinforcement member for use, thereby makes that whole optical cable weight is lighter.
Protective jacket comprises armor 2, aramid fiber enhancement Layer 3 and low-smoke non-halogen flame-retardant outer jacket 4 from the inside to the outside successively, add man-hour, be to twine metal armouring in butterfly optical cable body periphery, wrapped again aramid yarn forms aramid fiber enhancement Layer 3 outside armor 2 then, at last at extrusion moulding outer jacket 4, because metal armouring layer 2 is set, optical cable has the mouse bite preventing performance, the setting of aramid fiber enhancement Layer 3 can strengthen the ability of lateral pressure resistant and stretching, not only can be used for indoorly, also can be used for the outdoor of inclement condition.
In order to prevent that optical fiber from making moist, between butterfly optical cable body 1 and armor 2, also be provided with many water blocking yarns 5.
That the present embodiment optical cable has is in light weight, lay advantage easily, and its processing technology is also simpler, and the yield rate height has well anti-mouse and stings and high-intensity lateral pressure resistant ability, can be used for the occasion of indoor and outdoors and inclement condition simultaneously.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this; can not limit protection domain of the present utility model with this; core number as optical fiber is not limited to two cores; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
