After late nineteen eighties optical fiber loose tube technological invention in last century, the cable technology of optical fiber is leaped, promoted a large amount of uses of optical cable, also promoted modern communications.Optical fiber loose tube stranding type cable is mainly used outdoor, all needs to adopt longitudinal water-blocking technology, to prevent that water from infiltrating optical cable, causes the increase of fibre loss, reduces the serviceable life of optical cable.At present, optical cable longitudinal water-blocking technology is to fill the longitudinal water-blocking that the thick compound that blocks water is realized optical cable in optical fiber loose tube, between stranded optical cable core, between sheath and sheath.And the thick compound that blocks water of filling in optical cable is if optical cable cream is in production and use procedure, the thick compound that blocks water can be at some parts of equipment, as residual some ointment in guide wheel, Go-over mould and cable core take-up reel tool, and the compound-material that blocks water is not easy to remove, be difficult to clean, both pollute production equipment, also polluted environment, also greatly increased continue operation and test duration simultaneously.
Utility model content
Shortcoming and defect for existing optical cable longitudinal water-blocking technology, the utility model has been abandoned the thick compound that blocks water of filling in optical cable, replace with dry type material water-proof material, simultaneously in loose sleeve pipe and cable core without the thick compound that blocks water, between optical cable components, have higher friction factor, this will make itself and reinforcement obtain better coupling.
The utility model is by the following technical solutions:
A kind of dry type non-metallic optical fiber cables, comprise cable core, described cable core is by center non-metal reinforcement member, pine sleeve pipe and gasket for packing form, in described loose sleeve pipe, be provided with multifiber and water blocking yarn, described loose sleeve pipe and described gasket for packing are stranded in described center non-metal reinforcement member around, at described cable core, indulge bag cable core water blocking layer outward, described cable core water blocking layer arranges inner sheath outward, described inner sheath arranges oversheath outward, stranded between described inner sheath and described oversheath have a dry type pulling force enhancement layer that blocks water, described dry type blocks water pulling force enhancement layer for adopting dry type material water-proof material and pulling force reinforcement is stranded forms.
A kind of dry type non-metallic optical fiber cables described in the utility model, wherein, described center non-metal reinforcement member outer wrapping dry type water blocking layer, what described dry type water blocking layer adopted is dry type material water-proof material.
A kind of dry type non-metallic optical fiber cables described in the utility model, wherein, what described cable core water blocking layer adopted is dry type material water-proof material.
A kind of dry type non-metallic optical fiber cables described in the utility model, wherein, described dry type material water-proof material is modified water absorbent expanding material.
A kind of dry type non-metallic optical fiber cables described in the utility model, wherein, described modified water absorbent expanding material is super absorbent resin.
A kind of dry type non-metallic optical fiber cables described in the utility model, wherein, described pulling force reinforcement is aramid fiber reinforcement.
A kind of dry type non-metallic optical fiber cables described in the utility model, wherein, described center non-metal reinforcement member is glass fiber reinforced plastics (FRP).
The beneficial effect of a kind of dry type non-metallic optical fiber cables that the utility model provides is: the utility model has been abandoned the thick compound that blocks water of filling in optical cable, replace with dry type material water-proof material, simultaneously in loose sleeve pipe and cable core without the thick compound that blocks water, between optical cable components, have higher friction factor, this will make itself and reinforcement obtain better coupling; And the utility model is simple in structure, longitudinal water-blocking successful, has guaranteed that optical cable has excellent block-water performance, and the environmental pollution when greatly reducing optical cable production and using, is convenient to the development and utilization of other optical cable simultaneously.
A kind of dry type non-metallic optical fiber cables that the utility model provides, described modified water absorbent expanding material is super absorbent resin, can absorb the water over 100 times of own wts, can absorb 1% sodium chloride solution of 30 times of about own wts, water absorptivity is stronger, and total cross-section block-water effect is good.
