Abstract
The utility model discloses a communications optical cable strengthens core and optic fibre including the center, optic fibre is other to be provided with the gasket for packing and to live the central core of strengthening with optic fibre cladding together, and optic fibre is got up and oleamen is expired to inside the packing, and the surface cladding that the core is strengthened at the center has the plastic -coated layer by the cladding of pine sleeve pipe, and the outside of optic fibre and gasket for packing has set gradually HDPE inner sheath, water blocking layer and the oversheath of resistant the track, all is provided with the enhancement steel wire in oversheath of nai track the and HDPE inner sheath, through adopting pine cover layer stranded type structure, the sleeve pipe intussuseption of will loosening is full of oleamen to and be provided with the water blocking layer and fill the anti erosive power that full optic fibre improves the rainwater with the cream that blocks water, reducing the influence power of rainwater, the rethread is provided with the enhancement steel wire makes the tensile strength of optical cable more excellent, makes the resistant track performance of optical cable more superior through being provided with the oversheath of nai the track. The utility model discloses simple structure, light in weight has reduced that sunshine, rain are beaten and the influence of wind -force, and life has increased.
Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of communications optical cable.
Background technology
The cable heart that communications optical cable is made up of some (core) optical fiber (generally from a few core to several thousand cores) and outer jacket formed.Optical fiber is compared with traditional symmetrical copper loop and coaxial copper loop, and its transmission capacity is much bigger, attenuation is few, transmission range is long, volume is little, lightweight, without electromagnetic interference (EMI), cost is low is the most promising current communications media.It is just being widely used on the Signal transmissions of all departments such as telecommunications, electric power, broadcast, to progressively become the main body of future communications network, but current most telecommunication cable is all erected at outside, receive Exposure to Sunlight and rain to beat and cause the aging more block of communications optical cable throughout the year, severe patient directly can damage cable, and the problem therefore solving this class seems particularly important.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of communications optical cable, by adopting loose sleeve layer strand type structure, and carries out waterproof by filling full ointment in Loose tube, strengthen water resistance further with water blocking layer, waterproof paste, affect problem to solve existing communication cable by what sunshine, rain was beaten.
In order to solve the problem, the utility model provides a kind of communications optical cable, include center strengthening core and optical fiber, described optical fiber is other to be provided with gasket for packing and to envelope center strengthening core together with optical fiber, described optical fiber is the full ointment of coated and inner filling by Loose tube, the outside surface of described center strengthening core is coated with coating layer, the outside of described optical fiber and gasket for packing is disposed with tygon inner sheath, water blocking layer and resistance to electric trace oversheath, in described resistance to electric trace oversheath and tygon inner sheath, be provided with reinforcement steel wire.
Further improvement is: fill full between described Loose tube with waterproof paste.
Further improvement is: be also provided with in the middle of described water blocking layer and resistance to electric trace oversheath that aramid fiber is wrapped to be enveloped tygon inner sheath.
Further improvement is: be provided with insulation course between described Loose tube and tygon inner sheath.
Further improvement is: described Loose tube is set to five, and described gasket for packing is set to one.
The beneficial effects of the utility model are: by adopting loose sleeve layer strand type structure, full ointment will be filled in Loose tube, and be provided with water blocking layer and fill with waterproof paste the corrosion resistance that full optical fiber improves rainwater, reduce the influence power of rainwater, making the tensile property of optical cable more excellent by being provided with reinforcement steel wire again, making the resistance to electric trace performance of optical cable more superior by being provided with resistance to electric trace oversheath.The utility model structure is simple, lightweight, and reduce sunshine, rain beats and the impact of wind-force, serviceable life adds.
