Description
Technical field
The present invention relates to optical cable field, specifically, be a kind of anti abrasive optical cable.
Background technology
Optical fibers, is called for short optical fiber, is the total reflection principle transmission in the fiber that glass or plastics are made of a kind of light
Light conduction instrument.Fine fiber package is in plastic sheath so that it can bend and be unlikely to fracture.Generally the one of optical fiber
The transmitting equipment of end uses light emitting diode or beam of laser that light pulse is sent to optical fiber, the reception equipment of the other end of optical fiber
Use photosensitive components detection pulse.The cable comprising optical fiber is referred to as optical cable.Owing to light exists than electricity in fibre-optic transmission loss
The loss of electric wire conduction is much lower, and more because main production raw material is silicon, reserves are very big, are easier to exploitation, so low price,
Optical fiber is promoted to be used as the media of information of distance.Along with optic fibre manufacture process field and manufacture apparatus field further
Optimizing or development, existing fiber price reduces further, and optical fiber improves the most rapidly at the total proportion of signal communication cable.Light
Cable is that a number of optical fiber forms the cable heart according to certain way, is surrounded by outward sheath, and the also cladding outer jacket having, in order to realize light
A kind of communication line of signal transmission.Along with informationalized development, the conveying capacity of information increases rapidly, and optical fiber cable has obtained greatly
The application of amount.The cable configuration used at present is relatively simple, and this optical cable is by single tight tube fiber and is coated on single and tightly overlaps
The restrictive coating of optical fiber surface is constituted, and the production technology of this optical fiber is relatively simple, the bad mechanical property of optical fiber, in construction or use
During be easily caused the bending of optical fiber or fracture, ultimately result in the Transmission of optical signal, had a strong impact on fiber-optic transfer special
The long-time stability of property.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the anti abrasive optical cable that optical cable service life can be extended.
The present invention is achieved through the following technical solutions: a kind of anti abrasive optical cable, outside setting gradually from outside to inside
Sheath and inner sheath, be provided with several ferrules in inner sheath, ferrule is built with some optical fiber, and oversheath is for adding
There is the sheath of nano titanium oxide.
Described oversheath is the PE sheath being added with nano titanium oxide.
Cable cream it is filled with between described inner sheath and ferrule.
Carry out bonding by epoxy resin adhesive between described ferrule.
Described oversheath and inner sheath are provided with fireprotection layer.
Described fireprotection layer is the fireprotection layer being made up of AFR/.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention is conducive to improving the wear-resisting intensity of oversheath, aging resistance by adding nano titanium oxide in oversheath
Ability, productive technique and weatherability, the service life being conducive to extending optical cable with this, and by adding nano titanium oxide
Make oversheath have self-cleaning function, it is possible to prevent dust accretions, be conducive to alleviating oversheath and be corroded in natural environment,
Oversheath can also be made to have the function of uv reflectance by adding nano titanium oxide, it is possible to avoid oversheath in illumination
Lower generation is aging；
(2) present invention makes to carry out bonding by epoxy resin adhesive between ferrule, is conducive to improving the machine of ferrule
Tool intensity, is conducive to increasing the strengths in tension and compression of the present invention, and epoxy resin has good dielectric properties, by using epoxy
Resin adhesive is conducive to improving the capacity of resisting disturbance of the present invention；
(3) present invention makes the present invention have good fire protecting performance by arranging fireprotection layer, optical cable can be protected to avoid with this
Being affected by fire or high temperature and be damaged, the fireprotection layer using AFR/12 material to make has good heat-proof quality, energy
Enough protection cable interior structures are not by high temperature, thus ensured the use safety of optical cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti abrasive optical cable；
Wherein 1 oversheath, 2 fireprotection layers, 3 inner sheaths, 4 ferrules, 5 optical fiber.
Detailed description of the invention

Rice titanium dioxide PE sheath, by oversheath 1 in add nano titanium oxide be conducive to raising oversheath wear-resisting intensity,
Ageing resistance, productive technique and weatherability, the service life being conducive to extending optical cable with this.
In the present embodiment, between described inner sheath 3 and ferrule 4, it is filled with cable cream.
In the present embodiment, carry out bonding by epoxy resin adhesive between described ferrule 4, make ferrule 4
Between carry out bonding by epoxy resin adhesive, be conducive to improve ferrule 4 mechanical strength, be conducive to increasing the present invention
Strengths in tension and compression, epoxy resin has good dielectric properties, by using epoxy resin adhesive to be conducive to improving this
The capacity of resisting disturbance of invention.
In the present embodiment, described oversheath 1 and inner sheath 3 are provided with fireprotection layer 2, and fireprotection layer 2 is be made up of AFR/12
Fireprotection layer, makes the present invention have good fire protecting performance by arranging fireprotection layer 2, optical cable can be protected to avoid by fire with this
Calamity or high temperature affect and are damaged, and the fireprotection layer 2 using AFR/12 material to make has good heat-proof quality, it is possible to protection
Cable interior structure is not by high temperature, thus ensured the use safety of optical cable.
