Optical fiber, abbreviation optical fiber is a kind of up to the total reflection principle biography for causing light in fiber made of glass or plastics
Defeated light conduction instrument.Optical cable is that a number of optical fiber forms the cable heart according to certain way, is surrounded by sheath, some also claddings outside
Outer jacket, to realize a kind of communication line of optical signal transmission.
Existing optical cable is isolated due to not having between optical fiber and optical fiber, causes optical fiber easy crosstalk in bending, serious shadow
The service life of optical fiber is rung, and the production technology of optical fiber is relatively simple, the bad mechanical property of optical fiber, is constructing or was using
Easily cause the bending of optical fiber in journey or fracture, because the number of fibers placed in optical cable is few, fibercuts ultimately results in light letter
Number Transmission, had a strong impact on the long-time stability of optical fiber transmission property.
In order to overcome disadvantages mentioned above, the positive innovation research of those skilled in the art, to create a kind of new optical cable.
The content of the invention
The present invention solves the technical problem of providing a kind of optical cable, the mutual string between preventing when optical fiber from using
Disturbing causes jitter, adds the service life of optical fiber, and can place multifiber, in a part of fibercuts not
Influence overall using effect, waterproofing type aramid yarn causes optical cable to have a certain degree of water proofing property, and Kevlar fiber is deposited
Causing optical fiber flexible without fractureing, the presence of structure of fiber_optic causes multifiber may be present in pipeline, improves communication
Speed.
In order to solve the above technical problems, one aspect of the present invention is：A kind of optical cable is provided, including cable core,
Be coated on the isolation strip outside the cable core and the sheath being coated on outside the isolation strip, the cable core include ring support,
Center reinforcemen and several Loose tubes for being uniformly embedded on the ring support positioned at the ring support center, it is described
Center reinforcemen is fixedly connected with the ring support, and structure of fiber_optic is all provided with the Loose tube, and some optical fiber uniformly divide
Cloth is on the structure of fiber_optic and inlays and is connected with the structure of fiber_optic.
Further say, the gap filling waterproofing type virtue between the Loose tube, the ring support and the isolation strip
Synthetic fibre yarn, the center filling filling member of the structure of fiber_optic.
Further say, the outer surface of the ring support is provided with Loose tube groove, and each Loose tube is all located at institute
State in Loose tube groove, the diameter of the Loose tube groove is equal with the diameter of the Loose tube.
Further say, the outer surface of the structure of fiber_optic is provided with fiber grooves, and each optical fiber street is located at the light
In fine groove, the diameter of the fiber grooves is equal with the diameter of the optical fiber.
Further say, the sheath is PVC sheath.
Further say, the isolation strip is nylon material isolation strip.
Further say, the filling member is Kevlar fiber filling member.
The beneficial effects of the invention are as follows：
First, the present invention is provided with Loose tube, structure of fiber_optic, ring support, can place multifiber, greatly improve logical
Believe speed, and optical fiber is placed on structure of fiber_optic, effectively prevent mutual crosstalk of the optical fiber in bending, and can place more
Root optical fiber, ensure not influenceing overall using effect when part fiber is broken, improve the service life of optical cable.
2nd, waterproofing type aramid yarn is filled between isolation strip of the invention and Loose tube and ring support so that optical cable has
A certain degree of water proofing property；
3rd, the present invention is provided with fiber grooves, and optical fiber is placed on good fixing effect in fiber grooves so that optical cable bends the time
Fibre, which will not produce crosstalk, causes the damage of optical cable, improves communication efficiency, reduces cost；
4th, the present invention is provided with Kevlar fiber filling member, enables to optical fiber flexible without this section occurs, further carries
The high service life of optical fiber and cost-effective.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
