Abstract
The utility model relates to a rubber-covered optical cable. The rubber-covered optical cable has the characteristics of convenience in individual lead-out, safely, reliably and flexibility in use. The environment-friendly tightly-wrapped rubber-covered optical cable adopts the technical scheme that the environment-friendly tightly-wrapped rubber-covered optical cable comprises two optical fibers for transmitting optical signals, phosphorated steel wires positioned on the two sides of the optical fibers and used for strengthening, and a sheath material for wrapping and positioning the conductors and the phosphorated steel wires through extrusion. The environment-friendly tightly-wrapped rubber-covered optical cable is characterized in that a layer of flame-retardant PVC (polyvinyl chloride) material is tightly wrapped on the surface of each optical fiber. The flame-retardant PVC materials are 0.03-0.05mm in thickness. The sheath material is low-smoke, halogen-free and flame-retardant.
Description
Technical field
The utility model relates to a kind of covered wire cable, is mainly used in the house wiring of FTTH lightguide cable link, also is applicable to the optical cable of user's section of introducing of networks such as FTTO that other optical fiber insert and FTTB.
Background technology
Because having relatively high expectations of the service wire optical cable of FTTH (Fiber to the home) engineering, the bending property of conventional inside cable, tensile property can not satisfy the demand of FTTH house wiring; The substitute is that bending property is good, tension and the lateral pressure resistant ability is stronger, house wiring is attractive in appearance and can satisfy the covered wire cable of indoor use flame-proof environmental protection requirement.
Present covered wire cable mainly contains house wiring type GJ (F) XH optical cable and self-bearing type GJYX (F) CH drop type cable.Above covered wire cable can satisfy the cabling requirement of FTTX engineering basically, yet in some special occasions, when needing two optical fiber to draw separately, conventional covered wire cable can not well have been accomplished the requirement of separate cabling.Mainly be at the optical fiber of the section of drawing (promptly removing the fibre-optical splice end of oversheath) unprotect layer separately, consider that optical fiber itself is a kind of more crisp material, safe reliability is relatively poor when drawing separately.Like this, when specific occasions is used, the conventional covered wire cable underaction that seems.
Summary of the invention
The utility model technical matters to be solved is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of covered wire cable is provided, and this covered wire cable has the convenience of drawing separately, safe and reliable and use flexible characteristic.
The technical scheme that the utility model adopts is: environment-friendly type hard-pressed bale formula covered wire cable, comprise 2 propagating optical signals optical fiber, be positioned at the phosphatization steel wire that plays booster action of optical fiber both sides and through the protective cover material of extrusion molding with aforementioned conductor and phosphatization steel wire parcel location; The surperficial hard-pressed bale that it is characterized in that said optical fiber one deck flame-proof PVC material.
The thickness of said flame-proof PVC material is 0.03-0.05mm.
Said protective cover material is a low-smoke halogen-free flame-retardant sheath material.
The beneficial effect of the utility model is: because optical fiber has increased the fire-retardant hard-pressed bale material of one deck outward, fiber strength obtains bigger raising, draws when using can not fracture easily, and it is convenient flexible to construct, and safe and reliable.Protective cover material adopts low-smoke halide-free fireproof composite polyolefine material simultaneously, makes product have superior fire resistance, and reaches environmental requirement; Can a new solution be provided for the FTTX engineering.
Description of drawings
Fig. 1 is the lateral cross section structural representation of the utility model.
Embodiment
As shown in the figure, central coated one group of (2 core) optical fiber 3 of this environment-friendly type hard-pressed bale formula covered wire cable is tightly coating one deck flame-proof PVC material 2 around the optical fiber, and this layer material can play cushioning and protection when optical fiber is drawn separately; Optical fiber both sides symmetries is placed 2 phosphatization steel wires 1, can play the mechanical property effect (as recommendation, the axis of the axis of two optical fiber and two phosphatization steel wires preferably can be on same plane) of tension, enhancing to whole optical cable.Protective cover material 4 passes through extruded with aforementioned optical fiber and phosphatization steel wire parcel and location; Protective cover material is that low cigarette does not have the chlorine fire proofing, can increase withstand voltage, the wear-resistant protection function of optical cable.
The thickness of said flame-proof PVC material is recommended as 0.03-0.05mm.
The equal buyable of all material in the utility model.
Claims (2)
