Abstract
The utility model discloses a non metal skeleton-type optical fiber ribbon cable. The non metal skeleton-type optical fiber ribbon cable comprises a skeleton with skeleton grooves arranged on the circumference and skeleton rib marks for marking each skeleton groove; the center of the skeleton is also provided with a central non-metal reinforcement piece; the skeleton groove is internally provided with a optical fiber ribbon and filled with fiber ointment; polyester mangled gauze for restraining and protecting the optical fiber ribbon covers the optical fiber and the skeleton; and a marking ribbon, a composite-film water-blocking belt, a ripcord for opening the cable and an outer sheath are sequentially from inside to outside arranged outside the polyester mangled gauze. According to the non metal skeleton-type optical fiber ribbon cable, the weight is light; large pull force can be borne; the cable can be laid in a same pipeline mode with other cables in a community; and in the case of fiber to the home splicing, the optical fiber ribbon which is cut off is not likely to slide and break due to weight itself after being drawn out, and thus the splicing construction difficulty can be reduced.
Description
Technical field
The utility model relates to a kind of nonmetal slotted core fiber ribbon cable, particularly a kind of nonmetal slotted core fiber ribbon cable that is applicable to lay in vertical pipeline.
Background technology
In recent years along with the high speed development of communications optical cable and Fiber to the home technology (Fiber To The Home; FTTH) application and popularization, optical fiber access engineering construction process is obviously accelerated, to family, the cabling cloth method for fiber of (FTTH) mostly adopts tight sleeve optic cable and common loose jacket layer strand optical cable to existing fiber, when needs branch house lead in optical fiber, because opening separator window, can only cut off that optical cable continues or lay simultaneously and tap into many optical cables, therefore not only design is complicated, the amount of expending of optical cable is large, the pipeline space taking while laying is large, and a large amount of cable is crowded, and branch connection is very loaded down with trivial details.
The solution that slotted core cable is used for to FTTH is that the optical fiber of access optical cable is linked to some cross-connecting boxes from machine room, access again each housing unit, by open some separator windows on slotted core cable, just can directly extract the optical fiber that need to access resident family out, and needn't whole optical cable be cut off by common mode, because of without continuing and only needing the optical cable of minute quantity, greatly simplify and facilitated design and the construction of FTTH.
In addition, the general vertical shaft corridor that adopts of apartment-type building accesses, optical cable accesses from corridor bottom, separator window can obtain by peeling off sheath, the waterstop of optical cable at the scene, the unlatching of separator window is generally undertaken by floor order from top to bottom, if extract a fibre ribbon at certain layer, should be first thereon the separator window of one deck this fibre ribbon is cut off, distance between adjacent two windows can guarantee that the optical fiber of extracting out, with enough length, then changes into tail optical fiber house lead in by connector box by fibre ribbon.Aforementioned fiber-to-the-home continuing in work, the fibre ribbon blocking is because the landing fine phenomenon of breaking easily appears in Gravitative Loads, thereby increases the difficulty of construction of the work that continues, and therefore, the structure of optical cable still needs to be further improved.
Summary of the invention
The purpose of this utility model is: a kind of nonmetal slotted core fiber ribbon cable is provided, and in order to solve in user's special line continues to family, the technical matterss such as the disconnected fibre of landing easily appear in fibre ribbon.
The utility model is that the technical scheme that its technical matters of solution adopts is: a kind of nonmetal slotted core fiber ribbon cable, include the skeleton of circumferentially offering skeleton grooves, for identifying the skeleton rib mark of each skeleton grooves, it is characterized in that: the center of skeleton is also provided with center non-metal reinforcement member, in described skeleton grooves, be placed with fibre ribbon and be filled with fine ointment, for retraining and protecting the polyester of fibre ribbon to prick in yarn is coated on described optical fiber and skeleton, outside described polyester is pricked yarn, from inside to outside, be disposed with mark band, multiple film waterstop, that opens that cable uses tears rope and oversheath.
The optical cable strengthening core that aforementioned center non-metal reinforcement member adopts glass fiber reinforced plastics to make.
The beneficial effects of the utility model are, due to the cable core of traditional metal material is replaced to center non-metal reinforcement member, thus when reducing whole optical cable weight, optical cable still can bear enough pulling force, in fact, optical cable self could also bear larger pulling force when the weight of optical cable is compared conventional pipelines optical cable and greatly alleviated! In addition, the utility model adopts nonmetal skeleton, in community, can same pipeline laying with cable, and without worrying, produce interference phenomenon, both improved operating efficiency, also can reduce difficulty of construction and cost; Fibre ribbon periphery in each skeleton grooves is filled with fine ointment on the other hand, and Fiber to the home while continuing, the fibre ribbon of cut-out, after it is drawn out of, is difficult for landing disconnected fine, thereby can further reduce the difficulty of the construction that continues.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of nonmetal skeleton loose fibre optical cable described in the utility model.
In figure: 1, skeleton rib mark, 2, center non-metal reinforcement member, 3, skeleton, 31, skeleton grooves, 4, fibre ribbon, 41, fine ointment, 5, polyester pricks yarn, 6, mark band, 7, multiple film waterstop, 8, polyester tears rope, 9, oversheath.
Embodiment
Shown in Figure 1, a kind of nonmetal slotted core fiber ribbon cable, include the skeleton 3 of circumferentially offering skeleton grooves 31, for identifying the skeleton rib mark 1 of each skeleton grooves, the center of skeleton be also provided with for strengthen optical cable can bearing tension center non-metal reinforcement member 2, in described skeleton grooves, be placed with fibre ribbon 4 and be filled with fine ointment 41, for retraining and protecting the polyester of fibre ribbon 4 to prick yarn 5, in described fibre ribbon 4 is coated on skeleton 3, outside described polyester is pricked yarn 5, from inside to outside, set gradually and be useful on the mark band 6 that indicates customer information, play the multiple film waterstop 7 of resistance effect, for stripping oversheath, opening the polyester that cable uses tears rope 8 and is arranged on outermost layer for the protection of the outer protective polyethylene cover 9 of optical cable.
The optical cable strengthening core that aforementioned center non-metal reinforcement member 2 adopts glass fiber reinforced plastics to make, as the structural strengthening element of non-metallic optical fiber cables.When reducing optical cable weight, can also improve the pulling force that it can bear.
The fibre ribbon periphery of the utility model in each skeleton grooves is filled with fine ointment, continues when construction Fiber to the home like this, and the fibre ribbon after blocking, because the existence of fine ointment is not generally prone to because of the disconnected fine phenomenon of deadweight landing, effectively reduces difficulty of construction.The construction of registering one's residence, continue of the optical cable that this advantage is specially adapted to arrange in vertical pipeline.
In addition, the utility model adopts nonmetal skeleton, in community, can same pipeline laying with cable, and without worrying, produce interference phenomenon, both improved operating efficiency, also can reduce difficulty of construction and cost.
