Description
Technical field
The present invention relates to a kind of ultra-fine diameter high-performance jumper wire optical cables, and in particular to excellent to a kind of tensile property and weather resistance
Good high-performance jumper wire optical cable.
Background technology
In recent years, as fiber optic communication is to FTTB（Fiber To The Building）、FTTO（Fiber-To-The-Office）、FTTH（Optical fiber arrives
Family）The development in equal directions and user are more next to optical fiber to room, fiber to the desk, the requirement of optical fiber to palm etc.
Higher, the jumper wire optical cable of plug and play type is rapidly developed, and each optical cable manufacturer, which also increases, researches and develops jumper wire optical cable
With the input of production.However, currently used jumper wire optical cable, structure is mostly that multiply aramid fiber is coated on around tight tube fiber, most
Outside sheath material is extruded to form.This optical cable can bear smaller pulling force and flat pressure, be widely used in the various network equipments
With the connection of the network terminal.But there is also some problems for this optical cable, carry out extruding or curved to it first in construction or use
When folding, fibercuts is easily caused so that transmission signal interruption is brought to operator or end user and bothers and lose；Secondly should
When fiber optic cable production jumper terminal, only tight tube fiber is connected with adapter connector, and the tensile property of optical cable and connector is poor, when more
After secondary hot plug, fixed fine fracture is easily caused, the service life of optical cable is influenced；In addition in wind power plant, medical treatment, aerospace, army
The special dimensions such as work, it is very high to performance requirements such as the ageing properties of optical cable, weather resistance, oil resistance, uvioresistants, it is existing normal
Rule jumper wire optical cable can not meet above-mentioned requirements.
For the above technical problems, jumper wire optical cable there are many having occurred, such as Chinese patent 200820059871.0
Though optical cable have preferable pulling force characteristic and anti-flattening energy, in larger plus-pressure, it is ensured that optical fiber is not broken, it sets
Set inside and outside two layers of sheath, size is larger, influence its indoors, computer room, inside communication equipment interconnection etc. is under narrow space
Wiring uses.Though for another example optical cable size described in Chinese patent 2010205003289.6 is small, good bending property, its draftability
Can be poor with weather resistance, the requirement under more severe communication environment cannot be met.
Invention content
Technical problem to be solved by the present invention lies in propose a kind of ultra-fine in view of the deficiency of the prior art
High-performance jumper wire optical cable, not only radial dimension is small for it, but also has excellent mechanical performance and weather resistance.
The present invention be solve the problems, such as it is set forth above used by technical solution be：Include optical fiber and oversheath, spy
It levies and is closely to coat non-metal reinforcement member in optical fiber periphery, outermost layer extrudes one layer of ultra-thin oversheath again.
By said program, the ultra-thin oversheath by crylic acid resin, epoxy resin photo-curing material, ETFE or
TPU etc. is high, and performance materials are made, or are made of materials such as ethylene-tetrafluoroethylene copolymer, thermoplastic polyurethane elastomer.
By said program, the unilateral wall thickness of the ultra-thin oversheath is 0.15~0.3mm.
By said program, the outer diameter of the ultra-thin oversheath is less than or equal to 1mm.
By said program, the optical fiber is made of the resin-coated coat in bare fibre outer surface, resin coating
Layer is ultraviolet curing acrylic resin material layer or the resin coating material layers with high temperature resistance.
By said program, the resin coating layer one-sided thickness is 0.15~0.2mm.
By said program, the fiber number is single.
By said program, the non-metal reinforcement member is poly(p-phenylene terephthalamide) synthetic fibers, the fragrant acyl of contraposition
Amine fiber or meta position aramid fiber.
By said program, the static buckling radius of the optical cable is less than 20mm, and dynamic bending radius is less than 35mm.
By said program, the tensile strength of the optical cable reaches 750MPa or 750MPa or more.
The beneficial effects of the present invention are：1, outer diameter is thin, light-weight, and bending property is excellent, and it is empty greatly to have saved wiring
Between resource, reduce construction cost；2, using flexible non-metallic reinforcing element and high-performance ultrathin oversheath, optical cable has fabulous
Mechanical performance and weather resistance, when bearing larger pulling force and flat pressure, optical fiber is not broken not damaged, meets pipeline, short distance
From aerial, wire jumper making, computer room, medical treatment, aerospace, wind-powered electricity generation industry, the multi-field use demand such as fiber entering household, and uses and apply
If convenient；3, dry type structure, each unit setting is reasonable, adapts under severe communication environment to cable outer diameter size, high temperature resistant
Performance, bending radius, tensile strength, especially as jumper wire optical cable when surpass million hot plugs and ensure that signal transmission quality carries
The increasingly higher demands gone out.
