Abstract
The utility model discloses a flexible optical cable, comprising coated optical fibers, composite fiber reinforced cores and a flame retarding sheath, wherein the composite fiber reinforced cores wrap the coated optical fibers, the flame retarding sheath sleeves the composite fiber reinforced cores, the composite fiber reinforced cores are respectively provided with a multilayer structure, and comprise from inside to outside, a carbon fiber layer, a polyethylene fiber layer and a thermoset epoxy resin layer, and the flame retarding sheath is manufactured by a PVC material or a halogen free flame retarding material. The flexible optical cable is excellent in tensile strength and smaller in bending radius, can satisfy the demands of indoor optical cable arrangement, simultaneously is low in cost and high in cost performance, and is in accord with the demands of rapidly propelling fiber-to-the-home (FTTH) construction.
Description
Technical field
The utility model relates to the optical cable field, relates in particular to a kind of flexible optical cable.
Background technology
In order to accelerate informatization, need to strengthen the laying of fiber optic cable networks, advance construction and the development that Fiber to the home (FTTH).Optical cable comprises optical fiber, strengthening core and sheath.The strengthening core of the use in the optical cable mainly comprises spun glass strengthening core, metal strengthening core and aramid fiber strengthening core.For inside cable, require to possess following several characteristics in indoor laying: well flexibility, stronger stretch-resistance, certain side impact resistance, have anti-thunderbolt ability.For above several characteristic requirements, strengthening core commonly used at present is defectiveness all:
The metal strengthening core has metallic character, does not possess anti-thunderbolt ability, is not suitable for using as inside cable.
The spun glass strengthening core have stretch-resistance, corrosion-resistant, can prevent thunderbolt, be in inside cable, to use at present more strengthening core.But the flexibility of spun glass strengthening core is poor, fractures easily, weight is bigger., house wiring, cause the basic role of strengthening core to completely lose when constructing often easily because be bent and produced and fracture by knotting.
The aramid fiber strengthening core possesses flexibility, stretch-resistance, side impact resistance, also can prevent thunderbolt, though on the performance the application requirements of complete compound inside cable, the aramid fiber strengthening core costs an arm and a leg, general family is difficult to bear its price.
The utility model content
The utility model is intended to propose a kind of with low cost, can satisfy the flexible optical cable of inside cable application requirements again.
Embodiment according to the utility model proposes a kind of flexible optical cable, comprising: coated fiber, composition fiber strengthening core and fire retardant jacket.The composition fiber strengthening core is coated on outside the coated fiber.Fire retardant jacket is enclosed within outside the composition fiber strengthening core.
In one embodiment, the composition fiber strengthening core is a sandwich construction, comprises carbon fiber layer, polyethylene fiber layer and thermosetting epoxy resin layer from the inside to the outside successively.
In one embodiment, flexible optical fibre has 1～4 coated fiber.
In one embodiment, fire retardant jacket is made by PVC or bittern-free flame-proof material.
The flexible optical cable of the utility model has good tensile strength, littler bending radius, can satisfy the needs of present indoor laying optical cable.Simultaneously, the cost of this flexible optical cable is lower, has high cost performance, the compound faster needs that Fiber to the home (FTTH) builds that advance.
Description of drawings
Fig. 1 has disclosed the structural drawing according to the flexible optical cable of an embodiment of the utility model.
Embodiment
With reference to shown in Figure 1, the utility model has disclosed a kind of flexible optical cable 100, and this flexible optical cable 100 comprises coated fiber 102, composition fiber strengthening core 104 and fire retardant jacket 106.
Coated fiber 102 is positioned at the position, bosom of flexible optical cable 100, and coated fiber 102 can be arranged 1～4, in the embodiment shown in fig. 1, shows 2 coated fibers 102.In one embodiment, coated fiber 102 can adopt G.657 optical fiber realization.
Composition fiber strengthening core 104 is coated on outside the coated fiber 102.In one embodiment, composition fiber strengthening core 104 is a sandwich construction, comprises carbon fiber layer, polyethylene fiber layer and thermosetting epoxy resin layer from the inside to the outside successively.The pull resistance of composition fiber strengthening core 104 and fold resistance all will be better than conventional glass fiber strengthening core far away.
Fire retardant jacket 106 is enclosed within outside the composition fiber strengthening core 104.In one embodiment, fire retardant jacket 106 is made by PVC or bittern-free flame-proof material.In one embodiment, bittern-free flame-proof material can be following material or their combination: phosphorus series non-halogen fire retardant, hydrate of aluminium, magnesium hydroxide, expansible graphite.
The flexible optical cable of the utility model has good tensile strength, littler bending radius, can satisfy the needs of present indoor laying optical cable.Simultaneously, the cost of this flexible optical cable is lower, has high cost performance, the compound faster needs that Fiber to the home (FTTH) builds that advance.
