Abstract
The invention discloses a novel rubber-covered-wire optical fiber and relates to an optical fiber. The novel rubber-covered-wire optical fiber includes a tightly-wrapped optical fiber and a protective sleeve wraps tightly the optical fiber. The cross section of the protective sleeve is of an 8-shaped structure formed by two crossed circles. The tightly-wrapped optical fiber is located at the center of the protective sleeve. The novel rubber-covered-wire optical fiber also includes two strengthened cores which are made of a metal and are located at the two circle centers of the protective sleeve respectively. The novel rubber-covered-wire optical fiber is high in strength, small in bending radius and significantly convenient and practical.
Description
Technical field
The present invention relates to a kind of optical fiber, 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, described tightly packaged fiber is positioned at the center of sheath, also comprise strengthening core, described strengthening core is two, adopts metal to make, 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, very convenient and practical.

Fig. 2 is the structural representation of tightly packaged fiber of the present invention.
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 described tightly packaged fiber 1 is positioned at the center of sheath 2, also comprise strengthening core 3, 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.
