Abstract
The utility model discloses a multicore wiring indoor optical fiber cable. The multicore wiring indoor optical fiber cable comprises a non-metallic center reinforcing element and a plurality of single core tight tube optical fibers which are arranged annularly and encompass the non-metallic center reinforcing element, and a reinforcing layer and a sheath encompass the single core tight tube optical fibers in sequence. The multicore wiring indoor optical fiber cable has better mechanical performance and environmental performance, is convenient to splice and supports high-capacity data transmission.
Description
Technical field
the utility model relates to a kind of inside cable.
Background technology
utilize the optical fiber communication of light transmitting fiber as the transmission medium of light, why can obtain develop rapidly in decades at this, are owing to it has (1) transmission frequency bandwidth, message capacity is big; (2) decay is little; (3) not determined by outstanding advantages such as electromagnetic interference (EMI); But the quality of light own is fragile; The defective that physical strength is low requires it to constitute optical cable at outer suit protecting sheathing; So that for it provides mechanical protection, be to the basic demand of protecting sheathing: guarantee make, lay, optical fiber does not rupture in the use, and suffered stress is little; Must in manufacture process, keep the original transmission performance of optical fiber, and guarantee that optical fiber transmission performance in long-term use is reliable and stable.
present normally used inside cable structure is comparatively simple; Constitute by single core tight tube fiber and the restrictive coating that is coated on single core tight tube fiber surface; The production technology of this inside cable is comparatively simple; But the mechanical property of interior optical cable is relatively poor, in use causes the bending or the fracture of optical fiber easily, causes the transmission of light signal to lose or interrupt.
Summary of the invention
the utility model purpose is: a kind of multicore distribution inside cable of mechanical property and environmental performance preferably that has is provided, its softness, flexibly, continue conveniently, and support the Large Volume Data transmission.
The technical scheme of
the utility model is: a kind of multicore distribution inside cable; Comprise nonmetal center reinforcing element; And arrange and be coated on some outer single core tight tube fibers of nonmetal center reinforcing element in the form of a ring, these some single core tight tube fibers also are coated with enhancement Layer and sheath outward successively.
The radical of
said single core tight tube fiber is generally 4,6,8,12.
said enhancement Layer is the aramid yarn enhancement Layer.
The material of
said sheath can be flame-proof polyvinyl chloride (PVC), low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU) or the like.
said single core tight tube fiber by bare fibre, be coated on the coat on bare fibre surface and be coated on the outer tight cover coating of coat and constitute.
The utility model has the advantages that:
Some single core tight tube fibers are adopted in
1, the utility model, make optical cable integral body have external diameter little, in light weight, be prone to peel off, advantage such as good bending property.
2, the utility model are provided with the aramid yarn enhancement Layer between some single core tight tube fibers and sheath, can improve the mechanical property and the environmental performance of inside cable.
3, the utility model continue conveniently, and support the Large Volume Data transmission, can be used for house wiring, use as optical distribution cable, and the light that also can be used for tail optical fiber, wire jumper, optical communication equipment machine room, Optical Distribution Frame connects.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the radial section synoptic diagram of the utility model.
wherein: 1 nonmetal center reinforcing element; 2 single core tight tube fibers; 21 bare fibres; 22 coats; 23 tight cover coatings; 3 aramid yarn enhancement Layers; 4 sheaths.
Embodiment
embodiment: as shown in Figure 1; A kind of multicore distribution inside cable; Comprise nonmetal center reinforcing element 1; And arrange and be coated on some single core tight tube fibers 2 outside the nonmetal center reinforcing element 1 in the form of a ring, also be coated with aramid yarn enhancement Layer 3 and sheaths 4 successively outside these some single core tight tube fibers 2.
The material of
said sheath 4 can be flame-proof polyvinyl chloride (PVC), low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU) or the like.
said single core tight tube fiber 2 by bare fibre 21, be coated on the coat 22 on bare fibre 21 surface and be coated on coat 21 outer tight cover coatings 23 and constitute.
The radical of
said single core tight tube fiber 2 is generally 4,6,8,12, has just enumerated a kind of multicore distribution inside cable that includes 12 single core tight tube fibers 1 among present embodiment Fig. 1.
the utlity model has mechanical property and environmental performance preferably; Soft, flexibly, continue conveniently; And support Large Volume Data to transmit; Can be used for house wiring, use as optical distribution cable, the light that also can be used for tail optical fiber, wire jumper, optical communication equipment machine room, Optical Distribution Frame connects.
Only be the concrete exemplary applications of the utility model more than
, the protection domain of the utility model is not constituted any limitation.Except that the foregoing description, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
