Description
Technical field
The present invention relates to a kind of optical cable, relate in particular to a kind of introducing and use covered wire cable.
Background technology
High speed development along with the optical-fiber network information age; Covered wire cable is widely used in the unique texture pattern of its good looking appearance, easy construction that Fiber to the home (FTTH) and the wireless base station zooms out in the network; For reducing the jointing of optical fiber when outdoor environment gets into indoor environment; Improve the convenience of network reliability and maintenance, the introducing of having developed all kinds of introducing modes is with the dual-purpose covered wire cable of indoor and outdoor.Introducing generally includes cable core and oversheath with covered wire cable; Cable core is formed by stacking by one or more rectangle rubber-insulated wire unit; The rubber-insulated wire unit comprises fiber unit, two interior reinforcements and inner sheath; Two interior reinforcements are symmetrically set in the both sides of fiber unit, and inner sheath is coated on the outside of fiber unit and interior reinforcement; It is circular that the cross section of oversheath is generally, and oversheath is coated on the outside of cable core.Interior reinforcement adopts glass fiber reinforced plastics rod (FRP rod), aromatic polyamide fiber reinforced plastics rod (KFRP rod) or steel wire usually, makes the rubber-insulated wire unit have certain resistance to tension; Inner sheath adopts the fire retardant jacket material, has anti-flammability, is suitable for indoor use; Oversheath can adopt common polythene (PE) protective cover material, also can adopt flame-retardant sheath material.In the rubber-insulated wire unit; The centerline of the center line of fiber unit and the interior reinforcement of both sides is on same plane; When the external force on acting on the rubber-insulated wire unit has perpendicular to the component on this plane; This plane is crooked along certain direction under external force, and corresponding bending is also done in whole piece rubber-insulated wire unit under the effect of external force.In order to make the rubber-insulated wire unit protect fiber unit more smoothly towards certain fixed-direction bending, the xsect of inner sheath is set to rectangle usually, the longer sides of rectangle and above-mentioned plane parallel.In addition, expose fiber unit, be provided with tearing port at the center of two longer sides of the xsect of inner sheath for the ease of strip off rubber-insulated wire unit.
Above-mentioned covered wire cable is when the construction wiring; Even in the bending radius scope of covered wire cable, carry out bending; The phenomenon of the damage of rubber-insulated wire unit, fibercuts also usually occurs, cause many inconvenience and loss, through long term studies to construction; Discovery is damaged, major cause of failure is in the construction wiring process, inconsistent the causing of bending direction of the oversheath and the cable core of covered wire cable often occur.
Summary of the invention
Technical matters to be solved by this invention provides a kind of introducing and uses covered wire cable, and the phenomenon that the rubber-insulated wire unit damages, internal optical fiber ruptures takes place because of the bending direction of oversheath and cable core is inconsistent when this introducing can prevent to construct wiring with covered wire cable easily.The technical scheme that adopts is following:
A kind of introducing comprises oversheath and cable core with covered wire cable; Cable core comprises at least one rubber-insulated wire unit, and the rubber-insulated wire unit comprises fiber unit, two interior reinforcements and inner sheath, and two interior reinforcements are symmetrically set in the both sides of fiber unit along the length direction of fiber unit; Inner sheath is coated on the outside of fiber unit and interior reinforcement; Oversheath is coated on the outside of cable core, it is characterized in that: also comprise at least one pair of outer reinforcement, outer reinforcement is located in the oversheath along the length direction of fiber unit; The plane parallel that each belongs to the interior reinforcement center line of the plane at outer reinforcement center line place and each root rubber-insulated wire unit.
