Abstract
The invention discloses an optical cable to the home of a vertically arranged fiber, comprising a flat sheath; a nonmetal reinforcer is arranged respectively at the two side ends inside the sheath; a plurality of colored fibers and a rip cord are buried in the middle of the sheath; the outer side of the sheath is provided with a power cord; the outer cover of the power cord and the sheath are integrated and formed; the two sides of the joint of the sheath and the outer cover are provided with rip grooves. The optical cable can be applied both outdoors and indoors and is provided with the power cord which is capable of branching, so that the transmission volume can be changed according to the actual requirement.
Description
Technical field
The present invention relates to a kind of longitudinal optical cable for optical fiber to house.
Background technology
Along with the growth of information and popularizing of network, effective means as high capacity, long Distance Transmission, optical cable has obtained a large amount of application, Fiber to the home, optical fiber is the direction of production development to machine to table, optical fiber, and along with the raising of people to bandwidth requirement, and the continuous decline of Fiber to the home (FTTH) every line cost, all promoted the development of FTTH.
Summary of the invention
The present invention seeks to: a kind of longitudinal optical cable for optical fiber to house is provided, and use occasion can be used from outdoor to indoor, but and be provided with the power lead of branch, can change its transmission capacity according to actual needs.
Technical scheme of the present invention is: a kind of longitudinal optical cable for optical fiber to house, comprise the sheath that is flat, and the two side ends in the sheath is respectively equipped with a non-metal reinforcement member, and the centre of sheath is embedded with some colored optical fibers and one and tears rope.
The further technical scheme of the present invention is: a kind of longitudinal optical cable for optical fiber to house, comprise the sheath that is flat, and the two side ends in the sheath is respectively equipped with a non-metal reinforcement member, and the centre of sheath is embedded with some colored optical fibers and one and tears rope; The outside of described sheath is provided with power lead, and the overcoat and the sheath of power lead are one-body molded, and the both sides of sheath and overcoat junction are provided with tearing groove.
Described colored optical fiber adopts anti-curved fiber.
Described sheath adopts low-smoke halide-free fireproof composite polyolefine material or nylon sheath wire.
Described non-metal reinforcement member adopts glass fiber reinforced plastics.
Advantage of the present invention is:
1, adopts anti-curved fiber to have minimum counter-bending radius, can lay, and do not influence the transmission performance of optical fiber perpendicular to wall.
2, add one group of power line on the optical cable side, can provide power supply protection for equipment, and easy branch.
3, the use of this kind optical cable is mainly: the 1-2 core is indoor, the 2-6 core be from outdoor in the building, make the use occasion of this cable from outdoor to indoor, can use, but the line of electric force of branch also can change its transmission capacity according to actual needs.
4, whole sheath adopts low-smoke halide-free fireproof composite polyolefine material or nylon sheath wire, and material needs good pliability and environmental performance when meeting flame retardant rating.
5, the non-metal reinforcement member in the cable, bear higher tensile force, common glass fiber reinforced plastics FRP and sheath can not be combined closely, so adopted special FRP to make it to reach good bond effect with sheath, the bigger pulling force that bears, this material is outside the performance that keeps existing FRP, when temperature reaches more than 150 ℃, a kind of material can be melted in the surface, and sheath and FRP are combined together, makes optical cable that mechanical property preferably be arranged.
6, in sheath, added and tearing rope and light is drawn be very easy to out stripping, need not to use speciality tool.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a structural representation of the present invention;
Wherein: 1 sheath; 2 non-metal reinforcement members; 3 colored optical fibers; 4 tear rope; 5 power leads; 6 overcoats; 7 tearing grooves.
Embodiment
Embodiment: as shown in Figure 1, a kind of longitudinal optical cable for optical fiber to house comprises the sheath 1 that is flat, and the two side ends in the sheath 1 is respectively equipped with a non-metal reinforcement member 2, and the centre of sheath 1 is embedded with some colored optical fibers 3 and one and tears rope 4; The outside of described sheath 1 is provided with power lead 5, and the overcoat 6 of power lead 5 is one-body molded with sheath 1, and sheath 1 is provided with tearing groove 7 with the both sides of overcoat 6 junctions.
Described colored optical fiber 3 adopts anti-curved fiber.
Described sheath 1 adopts low-smoke halide-free fireproof composite polyolefine material or nylon sheath wire.
Described non-metal reinforcement member 2 adopts glass fiber reinforced plastics.
The present invention adopts anti-curved fiber to have minimum counter-bending radius, can lay perpendicular to wall, and not influence the transmission performance of optical fiber.
The present invention adds one group of power line on the optical cable side, can provide power supply protection for equipment, and easy branch.
Use of the present invention is mainly: the 1-2 core is indoor, the 2-6 core be from outdoor in the building, make the use occasion of this cable from outdoor to indoor, can use, but the line of electric force of branch also can change its transmission capacity according to actual needs.
The whole sheath of the present invention adopts low-smoke halide-free fireproof composite polyolefine material or nylon sheath wire, and material needs good pliability and environmental performance when meeting flame retardant rating.
Non-metal reinforcement member of the present invention, bear higher tensile force, common glass fiber reinforced plastics FRP and sheath can not be combined closely, so adopted special FRP to make it to reach good bond effect with sheath, the bigger pulling force that bears, this material is outside the performance that keeps existing FRP, when temperature reaches more than 150 ℃, a kind of material can be melted in the surface, and sheath and FRP are combined together, makes optical cable that mechanical property preferably be arranged.
The present invention has added in sheath and tearing rope and light is drawn be very easy to out stripping, need not to use speciality tool.
