Abstract
The utility model discloses a self-supporting type multi-core drop cable, comprising a multi-core tight tube fiber, an aramid yarn sheath, a low-smoke halogen-free flame-retardant sheath and a single phosphatized steel suspension wire. The multi-core tight tube fiber is uniformly distributed in the middle. The aramid yarn sheath wraps the exterior of the multi-core tight tube fiber. The single phosphatized steel suspension wire is located above the aramid yarn sheath. The low-smoke halogen-free flame-retardant sheath wraps the outer circles of the aramid yarn sheath and the single phosphatized steel suspension wire. The cable of the utility model is convenient to lay, the fiber is reasonably converged, the amount of the cables is effectively reduced, the construction workload and the construction intensity are decreased, the cable laying efficiency is improved, and the cable laying cost is reduced.
Description
Technical field
The utility model relates to a kind of self supporting type multi-core 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 be developed greatly.In the optical fiber access engineering of FTTH network, according to the fiber entering household requirement of old district one-storey house and grange, generally need by making somebody a mere figurehead or laying fiber entering household along skin.And that original single core self-supporting butterfly leading in cable lays density is large, not easy to identify, and fiber cable laying cost and labour intensity are large, and it is large to be subject to the impact that external environment condition impacts.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 supporting type multi-core leading in cable, and this optical cable makes things convenient for laying task, rationally converges optical fiber, effectively reduce optical cable quantity, reduce construction working amount and construction intensity, improve fiber cable laying efficient, reduce the optical cable laying cost.
For solving the problems of the technologies described above, the utility model self supporting type multi-core leading in cable comprises multicore tight tube fiber, aramid yarn sheath, low-smoke halogen-free flame-retardant sheath and sub-thread phosphatization steel wire messenger wire, described multicore tight tube fiber is uniform between two parties, described aramid yarn sheath is coated on outside the described multicore tight tube fiber, described sub-thread phosphatization steel wire messenger wire is positioned at described aramid yarn sheath top, and described low-smoke halogen-free flame-retardant sheath is coated on described aramid yarn sheath and sub-thread phosphatization steel wire messenger wire outer ring.
Further, above-mentioned tight tube fiber is six cores.
Further, above-mentioned tight tube fiber is the 0.9mm tight tube fiber.
Because the utility model self supporting type multi-core leading in cable has adopted technique scheme, be that this optical cable comprises multicore tight tube fiber, aramid yarn sheath, low-smoke halogen-free flame-retardant sheath and sub-thread phosphatization steel wire messenger wire, the multicore tight tube fiber is uniform between two parties, the aramid yarn sheath is coated on outside the multicore tight tube fiber, sub-thread phosphatization steel wire messenger wire is positioned at aramid yarn sheath top, and low-smoke halogen-free flame-retardant sheath is coated on aramid yarn sheath and sub-thread phosphatization steel wire messenger wire outer ring.This optical cable makes things convenient for laying task, rationally converges optical fiber, effectively reduces optical cable quantity, reduces construction working amount and construction intensity, improves fiber cable laying efficient, reduces the optical cable laying cost.
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 supporting type multi-core leading in cable.
Embodiment
As shown in Figure 1, the utility model self supporting type multi-core leading in cable comprises multicore tight tube fiber 1, aramid yarn sheath 2, low-smoke halogen-free flame-retardant sheath 4 and sub-thread phosphatization steel wire messenger wire 3, described multicore tight tube fiber 1 is uniform between two parties, described aramid yarn sheath 2 is coated on outside the described multicore tight tube fiber 1, described sub-thread phosphatization steel wire messenger wire 3 is positioned at described aramid yarn sheath 2 tops, and described low-smoke halogen-free flame-retardant sheath 4 is coated on described aramid yarn sheath 2 and sub-thread phosphatization steel wire messenger wire 3 outer rings.
Further, above-mentioned tight tube fiber 1 is six cores.
Further, above-mentioned tight tube fiber 1 is the 0.9mm tight tube fiber.
This optical cable is applicable to grange and one-storey house area in old district generally needs by making somebody a mere figurehead or laying the optical fiber house lead in along skin, between the public Route Area of circuit, adopt multifiber cable can rationally converge optical fiber, effectively reduce optical cable quantity, reduce construction working amount and construction intensity, reduce laying cost; Each tight tube fiber in this optical cable can adopt color identification, and is easy for installation, is beneficial to maintenance; The multicore tight tube fiber can satisfy a plurality of users' fiber entering household demand; The special performances such as it is little that aramid yarn has density, and stretch modulus is very high, and the higher and fracture elongation of fracture strength is lower, and have from heavy and light and anti-lightning strike effect; Sub-thread phosphatization steel wire messenger wire can be used as the self-bearing type carrier from heavy and light, can increase the aerial cable span, be convenient to built on stilts or lay along skin, and can with the general sectional fixture of self-bearing type butterfly leading in cable, construction is convenient; Low-smoke halogen-free flame-retardant sheath provides effective protection to whole optical cable, has effect fire-retardant and that avoid producing smog and toxic gas.Tight tube fiber can adopt the fibre junction submode to dock with single core indoor optical cable in this optical cable, need not hot melt, easy construction, and in the available hot melt application in light shunt case place or field quick connector for installing construction, realization is connected with the light shunt case.
