Abstract
The invention discloses a layer-stranded optical cable, which consists of a cable core and a sheath which is coated outside the cable core, wherein the cable core is provided with a reinforcement sleeved with a cushion, a plurality of optical fiber units which are arranged at the periphery of the cushion in a stranded mode, a binding layer, a plurality of optical fiber units which are arranged at the periphery of the binding layer in a stranded mode, and a plurality of filling ropes from the inner side to the outer side in turn; the sheath consists of a waterproof tape which is coated outside the cable core, an inner protection layer which is extruded at the periphery of the waterproof tape, a steel tape armor layer which is longitudinally coated at the periphery of the inner protection layer, and a polyethylene outer protection layer which is coated outside the steel tape armor layer; and each optical fiber unit consists of a plurality of optical fibers, a loose sleeve which is coated outside the plurality of optical fibers, and fiber paste which is filled between the loose sleeve and the optical fibers. The optical fiber units are in double-layer stranded arrangement, the optical fiber number of a single optical cable is improved, and the optical fiber concentration is high; moreover, the steel tape armor layer which is arranged outside the inner protection layer improves the tensile property and lateral pressure resistance, the optical cable subjected to external force impact is not damaged, and a signal can be smoothly transmitted.
Description
Technical field
The present invention relates to a kind of layer-stranding cable,
Background technology
Along with developing rapidly of telecommunications, optical cable is extensively applied to telecommunications, and wherein layer-stranding cable is to use the most a kind of optical cable.Existing layer-stranding cable has only the fiber unit of the mutually stranded setting of one deck mostly, and fiber count is less, and the concentration degree of optical fiber is not high.
Summary of the invention
The object of the present invention is to provide the big and high layer-stranding cable of optical fiber concentration degree of a kind of number of fibers.
For addressing the above problem scheme of the present invention be: a kind of layer-stranding cable, it is by cable core, being wrapped in the outer sheath of cable core forms, described cable core is followed successively by the reinforcement that is arranged with bed course from the inside to the outside, the mutually stranded a plurality of fiber units that are arranged on the bed course periphery, the wrapping layer, mutually stranded wrapping layer several fiber unit of periphery and the Duo Gen gasket for packing of being arranged on, be filled with water-blocking material between described wrapping layer and the fiber unit, described sheath is by being wrapped in the outer waterstop of cable core, be extruded in the sheath of waterstop periphery, the vertical tygon outer jacket that is wrapped in the steel-tape armouring layer of sheath periphery and is wrapped in outside the steel-tape armouring layer is formed, and each described fiber unit is by multifiber, the fine cream that is coated on the outer loose sleeve pipe of multifiber and is filled between loose sleeve pipe and the optical fiber is formed.
Further, described steel-tape armouring layer is a wrinkle steel-tape armouring layer.
Optimize, parallel reinforcement is provided with stiffener in the described steel-tape armouring layer.
Each fiber unit has 4～6 optical fiber.
Because adopt such scheme, the present invention has the following advantages: fiber unit of the present invention is the mutually stranded setting of bilayer, has improved the fiber count that unit cable has, and optical fiber concentration degree height; Be arranged on tension, lateral pressure resistant performance that the outer steel-tape armouring layer of sheath has improved optical cable, guarantee that optical cable is injury-free after being subjected to external impacts, guarantee that signal can unimpeded must the transmission.
