Abstract
The invention relates to a reinforced central tubular optical fiber belt optical cable, which comprises a cable core and a sheath, wherein the cable core consists of an optical fiber belt, fiber paste, a sleeve and a wrinkle steel belt; and the sheath comprises a sheath material and a steel wire reinforcing piece. In the optical cable, a dual-parallel steel wire central tube structure is entrained in the sheath, so the stress of the optical cable is concentrated, the mechanical strength is improved, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of enhancement mode optical cable, particularly reinforced central tubular optical fibre band optical cable.
Background technology
Present domestic conventional cable is mainly circular configuration, the relative stressed concentrated lateral pressure resistant ability of optical cable, and a little less than stretch-proof, the anti-twisting property, serviceable life is short.
Summary of the invention
In order to solve above-mentioned drawback, the invention provides a kind of reinforced central tubular optical fibre band optical cable, comprise cable core and overcoat, cable core is by fibre ribbon, fine cream, sleeve pipe, the wrinkle steel band is formed, and overcoat comprises protective cover material and steel wire reinforcement composition, and wherein the steel wire reinforcement adopts parallel four steel wires design.
Wherein said reinforced central tubular optical fibre band optical cable, its feature also is: parallel four steel wire reinforcements are positioned at the protective cover material of cable core both sides.
Wherein by described reinforced central tubular optical fibre band optical cable, its feature also is: the parallel four steel wire reinforcements in the protective cover material are set to PBT sleeve pipe periphery and protective cover material periphery equidistant.
Wherein said reinforced central tubular optical fibre band optical cable, its feature also is: the optical cable stretch-proof can reach 4000N, lateral pressure resistant reaches 3000N.
Description of drawings

Fig. 2: the reinforced central tubular optical fibre band optical cable of the present invention structural representation.
Fig. 3: process chart of the present invention.
Embodiment
As shown in Figure 2, central tubular optical fibre band optical cable provided by the invention comprises, PBT sleeve pipe 4, in establish optical fiber 1 wherein and fill fine cream 2, and wrinkle steel band 5 is arranged at the periphery of PBT sleeve pipe 4, coat above-mentioned division center via the moulding one-tenth polyethylene sheath material 6 of cover, wherein steel wire reinforcement 3 is provided with the polyethylene sheath material 6 that is positioned at the cable core both sides, parallel four steel wire reinforcements in the protective cover material are set to PBT sleeve pipe periphery and protective cover material periphery equidistant, this four steel wires reinforcement about cable core each two, hold and be arranged above and below, constitute parallel four structure of steel wire thus, optical cable stretch-proof 4000N can be provided, lateral pressure resistant reaches 3000N, and has well antitorque, the shock resistance characteristic.
As shown in Figure 3, the central tubular optical fibre band optical cable through optical fiber warehouse-in-optical fiber coloring-optical fiber and band-cover mould-step of sheath installation finishes.
Thus, significantly strengthen the cable machinery performance, more help the reliable and stable of optical cable, prolong optical cable serviceable life.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of claim of the present invention.
