Yet, present central tubular optical cable generally comprises pipe core, fiber unit, optical fiber ointment, enhancement Layer and oversheath, fiber unit is located in the pipe core, optical fiber ointment is filled in the gap between fiber unit and the pipe core, oversheath is coated on the outside of sleeve pipe, and enhancement Layer is located between sleeve pipe and the oversheath.It is in order to protect fiber unit not to be damaged, to improve the intensity of optical cable that enhancement Layer is set.In the prior art, enhancement Layer adopts metal material, adopts metal material as enhancement Layer, and its advantage is the intensity height, and is effective to fiber optic protection, but lightning-arrest weak effect, and be subjected to the external environment condition effect of leakage easily and produce electromagnetic induction.Therefore above-mentioned central tubular optical cable can only be applied in general outdoor occasion.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of full medium central tubular optical fibre band optical cable, this full medium central tubular optical fibre band optical cable can prevent to be subjected to outside electric leakage environmental impact and anti-electromagnetic induction, be suitable for and power cable laying in one ditch, strong thunder and lightning district and sub-district are inserted and used, and have the function that good bending property and anti-rodent are nibbled.The technical scheme that adopts is as follows:
A kind of full medium central tubular optical fibre band optical cable comprises pipe core, ribbon-unit, optical fiber ointment and oversheath, ribbon-unit is located in the pipe core, optical fiber ointment is filled in the gap between ribbon-unit and the pipe core, oversheath is coated on the outside of pipe core, it is characterized in that: also comprise many glass fiber reinforced plastics bands, the glass fiber reinforced plastics band is located between pipe core and the oversheath along the length direction of ribbon-unit, and circumferentially evenly is provided with along the outer of pipe core.
Pipe core adopts polybutylene terephthalate or modified polypropene to make.Oversheath can adopt common polythene material or fire proofing (as low-smoke halide-free fireproof composite polyolefine material or polyvinylchloride) to make as required, to be fit to outdoor and indoor request for utilization.Ribbon-unit is a fibre ribbon that certain torque arranged or with a constant pitch superimposed body of stranded multifiber band mutually, every fibre ribbon can be 4,6,8,12 or 24 core bands, and it is wide that core is counted scope, can be fit to requirements of different users.
By adopting many evenly to be arranged on glass fiber reinforced plastics band (FRP band) that the pipe core periphery makes progress as reinforcing element, replace original enhancement Layer, make this full medium central tubular optical fibre band optical cable all adopt dielectric material to make, both had and prevented to be subjected to outside electric leakage environmental impact, anti-electromagnetic induction and lightning-arrest effect preferably, the have original employing metal material again central tubular optical cable intensity height that is enhancement Layer, the advantage that the optical fiber dense degree is high is suitable for and power cable laying in one ditch, strong thunder and lightning district and sub-district are inserted and used; In addition, many glass fiber reinforced plastics bands (FRP band) circumferentially evenly are provided with along the outer of pipe core, and the external diameter of optical cable is little, and optical cable has good bending property, and optical cable can be by any direction bending, easy construction, and have the function that anti-rodent is nibbled.
As preferred version of the present utility model, it is characterized in that: the wrapped outside of described glass fiber reinforced plastics band at pipe core.By adopting wrapped mode that the glass fiber reinforced plastics band is set, make optical cable have more good bendability, can be with any direction bending.
As preferred version of the present utility model, it is characterized in that: described glass fiber reinforced plastics band is made by thermosetting plastics.The glass fiber reinforced plastics band that adopts thermosetting plastics to make can prevent effectively that the oversheath in the production run from shrinking, and makes optical cable have good temperature performance.
As the further preferred version of the utility model, it is characterized in that: the outside surface of described glass fiber reinforced plastics band and pipe core is bonding by hot melt adhesive.Preferably between glass fiber reinforced plastics band and pipe core, make glass fiber reinforced plastics band and pipe core bonding with certain interval by the coated heat melten gel along the length direction of ribbon-unit, more preferably this is spaced apart 2.5～3.5m, again at the outside oversheath that coats of glass fiber reinforced plastics band, make the structure of optical cable more closely integrated, do not influence easy construction simultaneously.
As the further preferred version of the utility model, it is characterized in that: comprise that also water blocking yarn, water blocking yarn be located between pipe core and the glass fiber reinforced plastics band.Water blocking yarn is wrapped on the pipe core with a constant pitch, makes optical cable have well vertically water preventing ability.
