Abstract
The invention discloses the optical cable that a kind of tensile strength is high, several optical fiber jackets (3) including oversheath (1), being arranged in oversheath (1) and several optical fiber (4) being arranged in optical fiber jacket (3), be provided with several reinforcements (2) in oversheath (1).The invention has the beneficial effects as follows: the present invention can improve the tensile strength of oversheath by arranging reinforcement, and optical cable is unsettled lay time, improve its bending resistance, it is thus possible to reduce the amount of deflection of optical cable, it is to avoid high wind makes optical cable produce big rocking, the abrasion being conducive to reducing optical cable with this, when optical cable bends, by the bending of reinforcement, it is also possible to avoid optical cable to return to the state before bending under the effect of natural resiliency, the precision laid is prevented to be destroyed.
Description
Technical field
The present invention relates to optical cable field, specifically, be the optical cable that a kind of tensile strength is high.
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, lay the optical cable that convenient tensile strength is high.
The present invention is achieved through the following technical solutions: the optical cable that a kind of tensile strength is high, including oversheath, is arranged on outer protecting
Several optical fiber jackets in set and several optical fiber being arranged in optical fiber jacket, be provided with several reinforcements in oversheath.
Described reinforcement is evenly distributed in oversheath ringwise.
Described reinforcement is the reinforcement that tinsel is made.
Described reinforcement is the reinforcement that copper wire is made.
Described oversheath is the sheath that PE makes.
Cable cream it is filled with between described oversheath and optical fiber jacket.
Described optical fiber jacket is mutually bonded by epoxy resin adhesive.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention can improve the tensile strength of oversheath by arranging reinforcement, and optical cable is unsettled lay time, improve it
Bending resistance such that it is able to reduce the amount of deflection of optical cable, it is to avoid high wind makes optical cable produce big rocking, and is conducive to reducing light with this
The abrasion of cable, when optical cable bends, by the bending of reinforcement, it is also possible to avoid optical cable to return under the effect of natural resiliency
State before bending, prevents the precision laid to be destroyed；
(2) by the present invention in that reinforcement is uniformly distributed ringwise, be conducive to making reinforcement uniform to the booster action of oversheath
Distribution, when optical cable under tension, makes power be uniformly dispersed, it is to avoid local is destroyed；
(3) by the present invention in that carries out bonding by epoxy resin adhesive between optical fiber jacket, is conducive to improving optical fiber jacket
Mechanical strength, be conducive to increase the present invention strengths in tension and compression, epoxy resin has good dielectric properties, by use
Epoxy resin adhesive is conducive to improving the capacity of resisting disturbance of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of the optical cable that a kind of tensile strength is high；
Wherein 1 oversheath, 2 reinforcements, 3 optical fiber jackets, 4 optical fiber.

Reinforcement 2, can improve the tensile strength of oversheath 1 by arranging reinforcement 2, and optical cable is unsettled lay time, improve it and resist
Crooking ability such that it is able to reduce the amount of deflection of optical cable, it is to avoid high wind makes optical cable produce big rocking, and is conducive to reducing optical cable with this
Abrasion, when optical cable bends, by the bending of reinforcement 2, it is also possible to avoid optical cable to return under the effect of natural resiliency
State before bending, prevents the precision laid to be destroyed, in the present embodiment, fills out between described oversheath 1 and optical fiber jacket 3
It is filled with cable cream.
In the present embodiment, described reinforcement 2 is evenly distributed in oversheath 1 ringwise, by making reinforcement 2 ringwise
It is uniformly distributed, is conducive to the booster action uniform distribution making reinforcement 2 to oversheath 1, when optical cable under tension, makes power disperse
Uniformly, it is to avoid local is destroyed.
In the present embodiment, the reinforcement that described reinforcement 2 is made for copper wire, it is soft, light weight that copper wire has quality
Advantage, does not interferes with the bending of optical cable.
