Abstract
The utility model relates to a tensile loose jacketed stranded optical cable used in a photo-communication field. The tensile loose jacketed stranded optical cable includes a tensile loose jacketed stranded optical cable core and a sheath cladding the cable core. It is characterized in that two sides of the sheath are provided with rigid parallel reinforcement pieces symmetrically and the rigid parallel stiffeners are embedded in the sheath. The utility model has following beneficial effects. First, through arranging the rigid parallel reinforcement pieces symmetrically on the two sides of the sheath to be a part of tensile components, the tension that a central reinforcement core needs to bear is reduced, thereby reducing the diameter of the central reinforcement core, improving the bending capability of the optical cable and facilitating to the laying and using of the optical fiber. Second, the tensile strength of the optical fiber is improved under a premise of not increasing the structural size of the cable core and not using auxiliary reinforcement pieces such as an aramid fiber, a glass yarn and the like, thereby reducing the cost of the optical fiber. Third, the structure of the optical fiber and the core number can be diversified. The number of optical cable cores has a wide selection range. The tensile loose jacketed stranded optical cable can be applied to a backbone network and an access network. The tensile loose jacketed stranded optical cable can be installed by burying directly, through channels or in an aerial cable way. The application range of the tensile loose jacketed stranded optical cable is wide.
Description
Technical field
The utility model relates to a kind of tension loose sleeve layer strand type optical cable that is used for optical communication field.
Background technology
Existing layer-stranding cable is being used to direct-burried, is climbing and lay; Or other are because installation or service condition are badly fashionable to the field that pulling force characteristic is had relatively high expectations, and the structure of employing mostly is auxiliary reinforcements such as increase center strengthening core diameter or interpolation aramid yarn, organdy.Increase center strengthening core diameter can cause optical cable bending property variation, also can cause the optical cable overall dimensions to become big sometimes, the inconvenience construction.Add auxiliary reinforcements such as aramid fiber, organdy and cost an arm and a leg, can increase the optical cable manufacturing cost greatly.
The utility model content
The utility model technical matters to be solved is to provide a kind of tensile strength high to the problem that above-mentioned prior art exists, good bending property, low cost of manufacture, easy to use and the loose sleeve layer strand type optical cable that lays.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include the loose sleeve layer strand type optical cable core; Coat the sheath of cable core; It is characterized in that the parallel reinforcement of rigidity being set, and the parallel reinforcement of rigidity embeds in the sheath in the sheath symmetria bilateralis.
Press such scheme, the parallel reinforcement of described rigidity is 1～3 steel wire or FRP.
Press such scheme, said loose sleeve layer strand type optical cable core adds filler cells by loose sleeve pipe or loose sleeve pipe and the center strengthening core is stranded forms, and is laid with fiber unit in the loose sleeve pipe.
Press such scheme, said fiber unit is one or more in optical fiber, fibre bundle, the fibre ribbon.
Press such scheme, in cable core, be filled with water-blocking component or/and material water-proof material.
Press such scheme, be coated with inner sheath at the loose sleeve layer strand type optical cable core, inner sheath coats armor outward.
Press such scheme, between armor and inner sheath, be filled with water-blocking component or/and material water-proof material.
The beneficial effect of the utility model is: 1, through in sheath, being symmetrical set the parallel reinforcement of rigidity as one of tensile elements; Reduced the pulling force that the center strengthening core need bear; Thereby can reduce center strengthening core diameter, improve the optical cable bending property, be convenient to laying and using of optical cable.2, do not increase the cable core structure size, do not using the tensile strength that has improved optical cable under the prerequisite of auxiliary reinforcements such as aramid yarn, organdy, reducing the optical cable cost.3, structure and core number variation, it is big to contain the fiber number range of choice, is applicable to backbone network, Access Network, but mounting means direct-burried, pipeline, built on stilts, applied range.
