Abstract
The utility model relates to a reinforced indoor and outdoor dual-purpose fiber ribbon cable, comprising an outer sheath and optical fiber ribbons. The cable is characterized in that an inner sheath is covered out of the optical fiber ribbon, a first layer water blocking reinforcer disposed between the optical fiber ribbon and the inner sheath, the outer sheath is covered out of the inner sheath, and a second water blocking reinforcer is disposed between the inner sheath and the outer sheath. Beneficial effects of the cable are that: 1, a plurality of groups of optical fiber ribbons are overlaid to form an optical communication unit, thereby effectively improving transmission capacity of the optical cable and optical fiber density; 2, the cable is provided with two layers of the inner sheath and the outer sheath and two layers of the inner reinforced water blocking component and the outer reinforced water blocking component, so the optical cable has wonderful weather resistance and mechanical property, and bending property is good, a cable opening rope is disposed between the inner sheath and the outer sheath, providing convenience for directly connecting the cable into a room to perform divergent connection after the outer sheath is removed, and satisfying indoor and outdoor dual purpose requirements; 3, an all-dry structure is used, the design is reasonable, weight of the optical cable is light, satisfying requirements of overhead installation, and providing convenience for construction and connection.
Description
Technical field
The utility model relates to the dual-purpose optical fibre band optical cable of a kind of reinforced indoor and outdoor.
Background technology
Along with optical fiber communication, to FTTB(, Fiber To The Building), FTTO(Fiber-To-The-Office), FTTH(fiber-to-the-home front yard) etc. the development of direction, to the batch bunchy of optical cable use, the large capacity of Multi-core number uses and indoor and outdoor wiring is dual-purpose etc. that aspect has all proposed higher requirement.Although existing outdoor optical fibre band optical cable has advantages of that fiber number is more on the one hand, but because it adopts steel wire or other stiffeners as reinforcement, bending radius is large, in the time that house wiring especially connects up compared with narrow space, affect optical cable and use, even cause the impaired of optical cable; Existing indoor optical-fibre band optical cable is mostly below 12 cores and only have one deck sheath on the other hand, although have less bending radius, its transmission capacity, block-water performance and mechanical property can not meet outside run requirement.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency existing for above-mentioned prior art and proposes the dual-purpose optical fibre band optical cable of a kind of reinforced indoor and outdoor, it not only has higher density of optic fibre and larger transmission capacity, and there is excellent mechanical property, weather resistance, block-water performance and bending property, can meet indoor and outdoor cabling requirement simultaneously.
The utility model for the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include oversheath and fibre ribbon, it is characterized in that fibre ribbon outer cladding inner sheath, between fibre ribbon and inner sheath, be provided with the ground floor reinforcement that blocks water, inner sheath outer cladding oversheath is provided with the second layer reinforcement that blocks water between inner sheath and oversheath.
Press such scheme, described optical fiber belt carcass number is 4 cores, 6 cores, 8 cores, 12 cores or 24 cores.
Press such scheme, described fibre ribbon is one or more layers, and described fiber number is 4～216 cores.
Press such scheme, described oversheath and inner sheath are all flat, and described fibre ribbon is parallel to be overlayed in inner sheath.
Press such scheme, the described ground floor reinforcement that blocks water is water resistance aramid fiber yarn or the glass fiber yarn that blocks water; The described second layer reinforcement that blocks water is water resistance aramid fiber yarn or the glass fiber yarn that blocks water.
Press such scheme, described inner sheath is made up of LSZH, PVC or other fire proofing.
Press such scheme, in oversheath, the second layer blocks water in reinforcement and is installed on out hawser.
The beneficial effects of the utility model are: 1, organize parallel being superimposed of fibre ribbon becomes optical communication element more, has effectively improved optical cable transmission capacity and density of optic fibre; 2, be provided with respectively inside and outside two-layer sheath and inside and outside two-layer reinforcement water-blocking element, optical cable has fabulous weather resistance and mechanical property, and bending property is good; Simultaneously between interior oversheath, arrange and open hawser, be convenient to remove after oversheath the directly indoor difference of carrying out of access and continue, meet the dual-purpose demand of indoor and outdoor; 3, adopt dry type structure, reasonable in design, optical cable is lightweight, meets the built on stilts requirement of laying, constructability and continuing.
Brief description of the drawings
Fig. 1 is the transversary sectional view of an embodiment of the utility model.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Include the fibre ribbon 1 being coated in inner sheath 3, fibre ribbon, by 4 parallel stacking together of 12 core optic fibre belt optics, adds up to 48 cores; Between fibre ribbon and inner sheath, be provided with the ground floor reinforcement 2 that blocks water, it is 8 1610dtex water resistance aramid fiber yarns that described ground floor is strengthened water-blocking element 2; Described inner sheath 3 is made up of halogen-free low-smoke flame retardant material, and its cross sectional dimensions is 3.5*5.5mm; At inner sheath, the second layer reinforcement 4 that blocks water is set outward, the described second layer blocks water, and to strengthen resistor be 8 600tex glass fiber yarns that block water; At the second layer reinforcement outer cladding oversheath 5 that blocks water, described oversheath is made up of vinyl polymer material, and its cross sectional dimensions is 6.5*8mm; In oversheath, the second layer blocks water in reinforcement and is installed on out hawser 6, open hawser and become diagonal angle to be distributed in both sides in oversheath, described in to open hawser be 1610dtex aramid yarn.
