Abstract
The utility model discloses a self-supporting type bow-type drop cable, comprising an FRP central reinforcement core, a plurality of single-core bow-type optical fibers, a water-blocking tape, a composite aluminum tape, multiple steel stranded wires and a polyethylene sheath. The plurality of single-core bow-type optical fibers are uniformly distributed at the outer circle of the FRP central reinforcement core. The plurality of single-core bow-type optical fibers are wrapped by the water-blocking tape. The composite aluminum tape is disposed at the outer circle of the water-blocking tape. The multiple steel stranded wires are located above the composite aluminum tape. The polyethylene sheath wraps the exteriors of the composite aluminum tape and the multiple steel stranded wires. By means of the self-supporting type bow-type drop cable of the utility model, overhead laying of cables can be performed conveniently, the overhead density is reduced, the cable laying cost and the labor intensity are decreased, and the cable laying efficiency is improved.
Description
Technical field
The utility model relates to a kind of self-bearing type butterfly leading in cable.
Background technology
Along with the needs of user to the raising of the network bandwidth, stability requirement and the contour band width service of development IPTV, the existing access way such as ADSL can not be satisfied the demand, and therefore can provide high bandwidth, high efficiency FTTH network to obtain great development space.In optical fiber access engineering, FTTH fiber entering household requirement according to grange and old district one-storey house, generally need by making somebody a mere figurehead or laying self-bearing type leading in cable house lead in along skin, and that original single core self-supporting butterfly leading in cable lays density is large, not easy to identify, fiber cable laying cost and labour intensity are large, and the impact that is subject to the external environment condition impact is large.Given this, be necessary to design a kind of new self-bearing type butterfly leading in cable to solve the problems of the technologies described above.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of self-bearing type butterfly leading in cable, utilizes this optical cable can conveniently implement the built on stilts of optical cable and lays, and reduces built on stilts density, reduces fiber cable laying cost and labour intensity, improves fiber cable laying efficient.
For solving the problems of the technologies described above, the utility model self-bearing type butterfly leading in cable comprises FRP center strengthening core, some single core butterfly optical fiber, waterstop, compound aluminium strip, multiply steel strand wires and pe sheath, described some single core butterfly optical fiber is distributed in strengthening core outer ring, described FRP center, described waterstop wraps up described some single core butterfly optical fiber, described compound aluminium strip is located at described waterstop outer ring, described multiply steel strand wires are positioned at described compound aluminium strip top, and described pe sheath is wrapped in outside described compound aluminium strip and the multiply steel strand wires.
Further, above-mentioned single core butterfly optical fiber is the six roots of sensation, eight or 12.
Because the utility model self-bearing type butterfly leading in cable has adopted technique scheme, be that this optical cable comprises FRP center strengthening core, some single core butterfly optical fiber, waterstop, compound aluminium strip, multiply steel strand wires and pe sheath, described some single core butterfly optical fiber is distributed in strengthening core outer ring, described FRP center, described waterstop wraps up described some single core butterfly optical fiber, described compound aluminium strip is located at described waterstop outer ring, described multiply steel strand wires are positioned at described compound aluminium strip top, and described pe sheath is wrapped in outside described compound aluminium strip and the multiply steel strand wires.Utilize this optical cable can conveniently implement the built on stilts of optical cable and lay, reduce built on stilts density, reduce fiber cable laying cost and labour intensity, improve fiber cable laying efficient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model self-bearing type butterfly leading in cable.
Embodiment
As shown in Figure 1, the utility model self-bearing type butterfly leading in cable comprises FRP center strengthening core 1, some single core butterfly optical fiber 2, waterstop 3, compound aluminium strip 4, multiply steel strand wires 5 and pe sheath 6, described some single core butterfly optical fiber 2 is distributed in strengthening core 1 outer ring, described FRP center, the described some single core butterfly optical fiber 2 of described waterstop 3 parcels, described compound aluminium strip 4 is located at described waterstop 3 outer rings, described multiply steel strand wires 5 are positioned at described compound aluminium strip 4 tops, and described pe sheath 6 is wrapped in outside described compound aluminium strip 4 and the multiply steel strand wires 5.
Further, above-mentioned single core butterfly optical fiber 2 is the six roots of sensation, eight or 12.
This cable configuration is simple, from heavy and light, anti-lightning strike, is applicable to many thunders and lightnings, the awful weather such as rainy, hot area.The area that disperses in grange, old district one-storey house and region, by making somebody a mere figurehead or laying this optical cable house lead in along skin, can rationally converge optical cable after adopting many single core butterfly optical fiber, effectively reduce optical cable quantity, reduce construction working amount and construction intensity, reduce laying cost, satisfy the needs of a plurality of user's optical fiber accesses; FRP center strengthening core is the structural strengthening element of optical cable in this optical cable, play the supporting role of some single core butterfly optical fiber, wherein FRP is glass fiber reinforced plastics, the FRP strengthening core is as a kind of structural strengthening element of non-metallic optical fiber cables, accepted extensively use by the optical cable industry, it is price and the good nonmetal load core of performance tool that the optical cable industry is generally admitted, the optical cable that uses FRP to make reinforcing element possesses following advantage: optical cable is insensitive to shocking by electricity, and is applicable to many thunders and lightnings, the awful weather area such as rainy, hot; Optical cable can be close to power lead and supply unit, not disturbed by induction current; Can not produce etchant gas and damage optical fiber; Intensity/the mass ratio of optical cable obviously is better than the metal strengthening core.Waterstop and compound aluminium strip play effective protective effect to some single core butterfly optical fiber; effect with dash, protection against the tide; and make things convenient for the stripping of opening of optical cable; the while pe sheath is wrapped in compound aluminium strip and the multiply steel strand wires make it consist of integral body outward; pe sheath has strengthened the hardness of whole optical cable; prevent damaging of optical cable; utilize the weight of multiply steel strand wires carrying optical cable; multiply Method of Steel Strand Stretching intensity is large; be conducive to the large span self-supporting; make somebody a mere figurehead, be hooked in power cable during wiring or lay along skin, simple to operate, easy construction.
