The optical fiber is a beam-tube optical fiber and can keep optical fiber beam tube under minimum deformation when the optical cable is bended; the protective sleeve is made by weaving and immersing glass yarns via polyimide resin, with good mechanical and chemical protective functions on the optical cable, and can work in the temperature range of -180 to +300 DEG C; and via utilizing the optical fiber whose stainless steel sleeve is filled by inert gas or added with a carbon sealing layer, the optical cable can be applied in the condition with high humidity, to protect the optical fiber from tidal air and hydrogen gas.
Description
Technical field
The utility model relates to communications optical cable, especially a kind of optical cable that can use under extreme temperature.
Background technology
Conventional communications optical cable serviceability temperature is in-50 ℃～+ 70 ℃ scopes, this be because: at first the serviceability temperature of the ultra-violet curing acryl resin coating of optical fiber itself only is-50 ℃～+ 85 ℃, secondly, the PBT beam tube of using always and the plastic sheath of optical cable all can't bear too high and low excessively extreme temperature.And need lay and use optical cable under extreme temperature in many instances, for example fire detection, low-temperature (low temperature) vessel, high temperature pipe detect, the Long-distance Control of hot system, the monitoring of steam-driven generator, the temperature-sensing system of working under the extreme temperature, and in military systems such as space flight, aviation, nuclear device, all need use the optical cable of under extreme temperature, working.Conventional optical cable can't satisfy the requirement of above-mentioned use occasion at all.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned technological deficiency, the utility model proposes a kind of optical cable, its serviceability temperature scope is-180 ℃～+ 300 ℃, can satisfy the requirement of extreme temperature under various occasions such as temperature sensing optic cable, communications optical cable.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of optical cable, has optical fiber, optical fiber is provided with the stainless steel sleeve pipe outward, optical fiber penetrates and constitutes optical fiber bundle tubes in the stainless steel sleeve pipe, stainless steel sleeve pipe outer wall is stranded the reinforcement steel wire, strengthen steel wire and be with sheath outward, sheath forms by the organdy establishment and with the polyimide resin dip-coating.
When this optical cable uses as if the environment of special humidity is following, in order to prevent the erosion action of moisture and hydrogen, filling with inert gas seal protection in the stainless steel sleeve pipe to optical fiber.
Optical fiber comprises the fibre coating that fibre cladding that fiber core, fiber core are outer and fibre cladding lay outward, and here, the fibre coating material is a polyimide.In order to prevent the erosion action of moisture, also one deck carbon sealant can be set outside fibre cladding.
The beneficial effects of the utility model are: this optical cable is a beam tube type cable, in the time of can guaranteeing that optical cable is crooked, and the deformation minimum that optical fiber bundle tubes bears; Sheath forms by the organdy establishment and with the polyimide resin dip-coating, and optical cable is had favorable mechanical and chemoproection effect, can work in-180 ℃～+ 300 ℃ temperature ranges; Utilize in the stainless steel sleeve pipe towards inert gas or the optical fiber that increases the carbon sealant this optical cable is used under the environment of special humidity, and avoid the effect of invading of moisture and hydrogen optical fiber.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of optical fiber.
Among the figure: 1. optical fiber, 11. fiber cores, 12. fibre claddings, 13. carbon sealants, 14. fibre coatings, 2. the stainless steel sleeve pipe is 3. strengthened steel wire, 4. sheath.
Embodiment
As shown in Figure 1, a kind of optical cable, has optical fiber 1, the optical fiber 1 outer stainless steel sleeve pipe 2 that is provided with, optical fiber 1 penetrates and constitutes optical fiber bundle tubes in the stainless steel sleeve pipe 2, stainless steel sleeve pipe 2 outer walls are stranded the steel wire 3 of reinforcement, strengthens the steel wire 3 outer sheaths 4 that are with, and sheath 4 forms by the organdy establishment and with the polyimide resin dip-coating.
As shown in Figure 2, optical fiber 1 comprises fiber core 11, the fiber core 11 outer fibre claddings 12 that lay and the fibre cladding 12 outer fibre coatings 14 that lay, and is provided with carbon sealant 13 between fibre cladding 12 and the fibre coating 14.Fibre coating is to be coating material with the polyimide resin.
Stainless steel sleeve pipe 2 adopts and stitches steel pipe the half a day of being made by the SUS304 stainless steel.Optical fiber bundle tubes then is after earlier stainless sleeve pipe 2 being stretched to required outside dimension, cleaning inwall with gases at high pressure earlier, and then optical fiber 1 is penetrated in the stainless sleeve pipe 2.Optical fiber 1 penetrates the method in the stainless steel sleeve pipe 2, and according to fiber number, the difference of stainless steel sleeve pipe 2 internal diameters and length can adopt methods such as vibratory drilling method, plunging, vacuum suction.The specification of stainless steel sleeve pipe 2 is as shown in the table:
Reinforcement steel wire 3 as reinforcing element can adopt the high strength low-carbon armouring wire, is stranded on the stainless steel beam tube, and gauge of wire and radical can be decided by physical dimension, but needs to guarantee to satisfy the bending property requirement of optical cable.Sheath 4, plastic sheath that need not be conventional, conventional cable jacket all can't satisfy the service condition of extreme temperature.The sheath 4 of this optical cable is to form by the organdy braiding and with the polyimide resin dip-coating, and it has favorable mechanical and chemoproection effect to optical cable, and can use under-180 ℃～+ 300 ℃ extreme temperature.
In the optical fiber bundle tubes of this optical cable, optical fiber 1 has certain surplus length, and to guarantee optical cable in laying and using, optical fiber is not subjected to the effect of extra-stress.
In the optical fiber bundle tubes of this optical cable, do not have the filling ointment, thereby help the cable laying operation of optical cable, help use yet as temperature sensing optic cable.
Optical cable in order to prevent the erosion action to optical fiber of moisture and hydrogen, can adopt following two kinds of methods to solve if when using under special wet environment:
One. can in stainless steel sleeve pipe 2, fill, as seal protections such as inflated with nitrogen or argon gas with inert gas shielding.
Two. adopt the optical fiber that carbon sealant 13 is arranged, shown in figure two, this type optical fiber is identical with aforementioned optical fiber, but is provided with one deck carbon sealant 13 between fibre cladding 12 and fibre coating 14, can prevent the erosion to silica fibre of hydrogen and moisture.
