Description
Technical field
The utility model relates to technical field of optical fiber, particularly outdoor self-supporting type armored optical cable.
Background technology
Along with network Development, present network can not be substituted, and network can constantly be upgraded, thus can improve constantly wiring continuous request, and systems provider and final user use optical fiber place-and-route product more and more when planning and planned network wiring system.Optical fiber place-and-route product no longer limitation be applied to trunk wiring system, also progress into the application such as fiber to the home (FTTH), fiber to the desk (FTTD).Several optical cables (GJYXFCH, GJYXCH, GJXH, GJXFH) that wiring optical cable (corridor is to user side) the butterfly leading in cable that current construction team uses generally adopts can frequently occur in maintenance, thus cause maintenance cost significantly to raise.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of compact conformation, and wiring takes up room little, simple to operation, and wiring use instrument is few, the outdoor self-supporting type armored optical cable of the good and long service life of tension, rodent-proof characteristic.
The purpose of this utility model is achieved through the following technical solutions: outdoor self-supporting type armored optical cable, it comprises upper jacket, lower jacket, reinforcement and fiber core, the outer wall of upper jacket is connected with the outer wall of lower jacket, described reinforcement is axially set in upper jacket along upper jacket, the inner side of described lower jacket is provided with braid, the inner side of braid is provided with steel belt layer, and the inner side of steel belt layer is provided with tight sleeve layer, and described fiber core is coated on the center of tight sleeve layer.
Described reinforcement is twisted layer steel wire.
Described braid is the wire sheathing of band fiber.
Described steel belt layer arranges opening, and described opening is sector structure, and the axial alignment of described sector structure opening direction and reinforcement.
The utility model has the following advantages:
1, simple, the compact conformation of the utility model structure, cable cross-sectional area is little, and wiring takes up room little.
2, the instrument used that connects up is wiring common tool, without the need to special specific purpose tool, and also simple to operation, save wiring cost.
3, in upper jacket, arrange twisted layer steel wire, strengthen tensile property, steel belt layer also has excellent tensile property simultaneously; simultaneously the multilayer such as sheath, braid, steel belt layer is arranged; multilayer protection is formed to fiber core, there is stronger rodent-proof characteristic, and then reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-upper jacket, 2-lower jacket, 3-reinforcement, 4-braid, 5-steel belt layer, 6-tight sleeve layer, 7-fiber core, 8-opening.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, outdoor self-supporting type armored optical cable, it comprises upper jacket 1, lower jacket 2, reinforcement 3 and fiber core 7, the outer wall of upper jacket 1 is connected with the outer wall of lower jacket 2, described reinforcement 3 is axially set in upper jacket 1 along upper jacket 1, and the inner side of described lower jacket 2 is provided with braid 4, and the inner side of braid 4 is provided with steel belt layer 5, the inner side of steel belt layer 5 is provided with tight sleeve layer 6, and described fiber core 7 is coated on the center of tight sleeve layer 6.
Further, described reinforcement 3 is twisted layer steel wire, and its pliability is strong, and protectiveness is good, not easily goes wrong, have certain toughness simultaneously when cloth concealed wire, can guarantee that optical cable has stronger anti-knotting ability.
Further, described braid 4 is the wire sheathing of band fiber.
Further, described steel belt layer 5 arranges opening 8, and described opening 8 is sector structure, and the axial alignment of described sector structure opening direction and reinforcement 3.
