Abstract
Provided is a stranded optical cable. The optical cable comprises a plurality of loose sleeves, each of which is internally provided with a plurality of light guide fibers and water blocking yarns. Filling ropes are arranged among the loose sleeves. A longitudinally-wrapped water blocking tape is arranged outside the filling ropes. A corrugated steel tape is arranged outside the longitudinally-wrapped water blocking tape. A polyethylene outer sheath is arranged outside the corrugated steel tape. The longitudinally-wrapped water blocking tape and the water blocking yarns quickly swell when exposed to water so as to achieve a water blocking effect. The corrugated steel tape and the filling ropes improve tensile strength of the optical cable to enable the optical cable to withstand a relatively large installation gap.
Description
Technical field
The present invention relates to a kind of optical cable, particularly there is the optical cable of the layer-twisted type structure of tension, water resistance.
Background technology
At present, optical cable is mainly to adopt optical fiber and the sheath outside cable core in loose sleeve pipe, loose sleeve pipe to form, and for anti-sealing and moisture enter optical cable, affects Optical Fiber Transmission effect, in loose sleeve pipe, place the fine cream that blocks water, outside cable core and cable core gap location fill the cable cream that blocks water, thus traditional optical cable in use, the clean expensive time of ointment, ointment pollutes the environment, can affect optical fiber quality, also can be subject to installing the restriction of drop, how restricted use occasion is also simultaneously.
Summary of the invention
In order to overcome the ointment contaminated environment in existing optical cable, affect the deficiency of fiber optic cable communications quality, the invention provides a kind of layer-stranding cable, it can not cause secondary pollution, has tension, water resistance, the high communication quality.
The technical solution adopted for the present invention to solve the technical problems is, layer-stranding cable comprises a plurality of loose sleeve pipes, in each loose sleeve pipe, be provided with many light transmitting fibers and water blocking yarn, between pine sleeve pipe, be provided with gasket for packing, gasket for packing is outward vertical bag waterstop, vertical bag waterstop is provided with embossing steel band outward, and embossing steel band is outward outer protective polyethylene cover.
The invention has the beneficial effects as follows, vertical bag waterstop and water blocking yarn are met water and are expanded rapidly, reach block-water effect; Embossing steel band and gasket for packing improve the tensile property of optical cable, make optical cable can bear larger installation drop.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. light transmitting fibers in figure, 2. water blocking yarn, 3. loose sleeve pipe, 4. gasket for packing, 5. vertical bag waterstop, 6. embossing steel band, 7. outer protective polyethylene cover.
Embodiment
In Fig. 1, layer-stranding cable comprises four loose sleeve pipes 3, in each loose sleeve pipe 3, is provided with many light transmitting fibers 1 and water blocking yarn 2, between pine sleeve pipe 3, be provided with gasket for packing 4, gasket for packing 4 is outer is vertical bag waterstop 5, the outer embossing steel band 6 that is provided with of vertical bag waterstop 5, and embossing steel band 6 is outer is outer protective polyethylene cover 7.
Claims (1)
1. a layer-stranding cable, it comprises a plurality of loose sleeve pipes, in each loose sleeve pipe, is provided with many light transmitting fibers and water blocking yarn, it is characterized in that: between loose sleeve pipe, be provided with gasket for packing, gasket for packing is vertical bag waterstop outward, and vertical bag waterstop is provided with embossing steel band outward, and embossing steel band is outward outer protective polyethylene cover.
