Abstract
The utility model discloses a small high-performance short-distance FTTH (Fiber To The Home) outdoor self-supporting optical cable which consists of an optical fiber unit, a supporting wire parallel to the optical fiber unit, and tight-fit sheaths arranged on the fiber unit and the supporting wire. A metal reinforcement piece is embedded in the tight-fit sheath of the optical fiber unit. The optical cable is improved in that the metal reinforcement piece and the supporting wire are both spliced through high-temperature glue coated on the surfaces thereof with the tight-fit sheaths. The tight-fit sheaths are tightly spliced with the reinforcement piece and the supporting wire through gluing, thereby ensuring that the reinforcement piece and the supporting wire can stretch or retract along with the tight-fit sheaths when the optical cable is under stress strain or undergoes temperature changes. The utility model solves the problem of degradation of the transmission performance and greatly improves the tensile property, the compression resistance, the bending resistance and the high and low temperature resistance of the optical cable.
Description
Technical field
The utility model relates to a kind of Fiber to the home outdoor optical cable, and particularly a kind of high strength optical fiber is to the small-sized optical cable of the outdoor short distance self-bearing type in family.This optical cable mainly is used in by the fiber cable branch point to the segment distance the user access point, and effect is that a part of optical fiber in the backbone optical cable is incorporated into user access point.
Background technology
In prior art, Fiber to the home the small-sized optical cable of outdoor short distance self-bearing type by fiber unit and the messenger wire parallel with fiber unit and be located at fiber unit and messenger wire on close-fitting sheath constitute, in the close-fitting sheath at cable core position, be embedded with metal reinforcement.Because reinforcement and messenger wire smooth surface, therefore, at optical cable during stressed or temperature variation, separate easily between reinforcement and messenger wire and the close-fitting sheath, produce relatively and slide, can not extend simultaneously or shrink, reduced the effect of reinforcement, make optic fibre force and the increase that decays, simultaneously, optical cable does not have the support of reinforcement, messenger wire when high temperature or low temperature, the elongation or the shrinkage amplitude of sheath all increase, and cause transmission performance to reduce.
The utility model content
The purpose of this utility model is at the problem in the prior art, provide a kind of high-performance optical fiber to the family the small-sized optical cable of outdoor short distance self-bearing type, to solve the problem that transmission performance descends, improve the temperature performance of optical cable simultaneously.
For achieving the above object, the technical solution of the utility model is as follows:
It is made of with messenger wire parallel with this fiber unit and the close-fitting sheath that is located on this fiber unit and the messenger wire fiber unit, be embedded with metal reinforcement in the close-fitting sheath at fiber unit position, its special construction is that described metal reinforcement and messenger wire all bond together by high-temp glue and the close-fitting sheath that is coated in its outside surface.
The further improved technical scheme of the utility model is as follows:
Described cable core is made up of single or double joint or multifiber or tight tube fiber or fibre ribbon, the close-fitting sheath cross section at described fiber unit position is Long Circle or rectangle, the cross section of the close-fitting sheath at described messenger wire position is circular, one end of the major cross-sectional axis of the close-fitting sheath in described fiber unit position links into an integrated entity by connecting band and the close-fitting sheath of messenger wire, be embedded with two metal reinforcements in the close-fitting sheath at fiber unit position, these two metal reinforcements serve as axle and rotational symmetry is arranged in the both sides of cable core with the cross section minor axis of the close-fitting sheath in cable core position.
By above-mentioned solution as can be seen, the mode that the utility model sticks with glue tightly bonds together close-fitting sheath and reinforcement and messenger wire, when having guaranteed the stressed or temperature variation of optical cable, reinforcement and messenger wire and close-fitting sheath extend simultaneously or shrink, solve the problem that its transmission performance descends, and strengthened the performance of tension, resistance to compression, bending resistance and the anti-high and low-temp of this optical cable greatly.
Description of drawings
Accompanying drawing, schematic cross-section of the present utility model.
Embodiment
Referring to accompanying drawing, this example is made of with messenger wire 2 parallel with this fiber unit and the close-fitting sheath that is located on this fiber unit and the messenger wire fiber unit 1, described fiber unit 1 can be single or double joint or multifiber or tight tube fiber or fibre ribbon, and this routine fiber unit is a double joint optical fiber.The cross section of the close-fitting sheath 3 in described fiber unit position is preferably Long Circle or rectangle, and in this close-fitting vest sheath 3, be embedded with two metal reinforcements 4, these two metal reinforcements are axle and rotational symmetry is arranged in the both sides of fiber unit 1 with the close-fitting sheath cross section minor axis 7 at fiber unit position, thereby fiber unit is formed clipping reinforcement structure.The cross section of the close-fitting sheath 5 at described messenger wire position is circular, and an end of the major cross-sectional axis 8 of the close-fitting sheath 3 in fiber unit position links into an integrated entity by the close-fitting sheath 5 of connecting band 6 and messenger wire.Earlier coat high-temp glue by extruder on the surface of metal reinforcement 4 and messenger wire 2, and then with close-fitting sheath material extrusion forming, metal reinforcement 4 and messenger wire 2 are bonded together tightly with close-fitting sheath.The V-shaped groove 9 in cross section among the figure is the easy lift-off structure of cable core that is located on the close-fitting sheath 3 in fiber unit position.
