Abstract
The invention discloses a novel rubber-insulated wire optical fiber and relates to a computer network accessory. The novel rubber-insulated wire optical fiber comprises a tightly-packaged optical fiber and a jacket covering the tightly-packaged optical fiber. The cross section of the jacket is shaped like an Arabic number 8 formed by two intersecting circles. The jacket is made of polyether sulfone. The tightly-packaged optical fiber is located in the center of the jacket. The novel rubber-insulated wire optical fiber further comprises two reinforcing cores which are made of metal and located in the two centers of circles of the jacket respectively. The novel rubber-insulated wire optical fiber is high in strength, small in bending radius, quite convenient to use and practical.
Description
Technical field
The present invention relates to a kind of computer network accessory, relate in particular to a kind of Novel covered wire optical fiber.
Background technology
In recent years, the optical fiber access market of China presented good growth momentum, and optical fiber access has become the focus in optical communication field.In optical fiber access engineering, be the most complicated link near user's house wiring, the bending property of conventional inside cable, tensile property can not meet FTTH(Fiber to the home) demand of house wiring.Therefore occurred rubber-insulated wire optical fiber, rubber-insulated wire optical fiber is relatively suitable for fixing, and the wiring that locus is more nervous can be used for open-wire line or short-range pipeline laying.At present in FTTH engineering, house wiring is had relatively high expectations to fibre-optical bending degree, the hard-pressed bale layer that the utilization of existing rubber-insulated wire optical fiber is coated on outside fibre core replaces cushion, make tightly packaged fiber can meet the installation requirement that bending radius is 5mm, but its intensity is low, in complicated indoor location process, be easily torn.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of Novel covered wire optical fiber, and intensity is high, and bending radius is little, very convenient and practical.
Technical scheme of the present invention is: a kind of Novel covered wire optical fiber, comprise tightly packaged fiber and be coated on the sheath outside tightly packaged fiber, the xsect of described sheath is the 8-shaped of two crossing circle compositions, sheath adopts polyethersulfone to make, described tightly packaged fiber is positioned at the center of sheath, also comprises strengthening core, and described strengthening core is two, employing metal is made, and lays respectively at two circle centre positions of sheath.
As preferably, described tightly packaged fiber comprises fiber core, be coated on covering outside fiber core, be coated on the resinous coat outside covering and be coated on the polyvinyl fluoride sheath outside resinous coat.
As preferably, described resinous coat is UV curing acrylic resinous coat.
As preferably, described polyvinyl fluoride sheath extrusion molding is outside resinous coat.
The invention has the beneficial effects as follows: in sheath of the present invention, be provided with strengthening core, described strengthening core adopts metal to make, and intensity is high, not only make optical fiber meet the requirement of minimum bending radius, also greatly strengthened the intensity of optical fiber.Sheath adopts polyethersulfone to make, and polyethersulfone has nontoxicity, self-extinguishing, and not adding any fire retardant has excellent flame retardancy, can reach UL94V-0 level (0.46mm).And hydrolysis, can resistance to 150～160 DEG C of hot water or steam, and at high temperature the also erosion of acid and alkali, alkali, has extended serviceable life of the present invention, very convenient and practical.

In figure: 1, tightly packaged fiber; 2, sheath; 3, strengthening core; 11, fiber core; 12, covering; 13, resinous coat; 14, polyvinyl fluoride sheath.
Embodiment
As one embodiment of the present invention, as depicted in figs. 1 and 2, a kind of Novel covered wire optical fiber, comprise tightly packaged fiber 1 and be coated on the sheath 2 outside tightly packaged fiber 1, the xsect of described sheath 2 is the 8-shaped of two crossing circle compositions, and sheath 2 adopts polyethersulfone to make, polyethersulfone has nontoxicity, self-extinguishing, not adding any fire retardant has excellent flame retardancy, can reach UL94V-0 level (0.46mm).And hydrolysis, can resistance to 150～160 DEG C of hot water or steam, and at high temperature the also erosion of acid and alkali, alkali, has extended serviceable life of the present invention.Described tightly packaged fiber 1 is positioned at the center of sheath 2, also comprises strengthening core 3, and described strengthening core 3 is two, adopts metal to make, and lays respectively at two circle centre positions of sheath 2.
In the present embodiment, as preferably, described tightly packaged fiber 1 comprises fiber core 11, be coated on covering 12 outside fiber core 11, be coated on the resinous coat 13 outside covering 12 and be coated on the polyvinyl fluoride sheath 14 outside resinous coat 13.
In the present embodiment, as preferably, described resinous coat 13 is UV curing acrylic resinous coat.Described polyvinyl fluoride sheath 14 extrusion moldings are outside resinous coat 13.
Above a kind of Novel covered wire optical fiber provided by the present invention is carried out to detailed introduction, applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof; , for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention meanwhile.To be possible to change of the present invention and improvement, and can not exceed design and the scope that accessory claim can specify.
