Abstract
The utility model discloses a unit optical cable. The unit optical cable comprises an optical fiber unit wrapped by optical fibers, wherein the sleeve of the optical fiber unit is a micropipe with the external diameter of 1.5mm; 12 optical fibers are integrated in the sleeve of the optical fiber unit; a structure for mounting the optical fibers in the sleeve of the optical fiber unit is a loose protective structure; the optical fiber unit is wrapped by a protecting jacket; and a filling protective body is filled between the optical fiber unit and the protecting jacket. Under the condition of the same optical fiber number, the external diameter of the optical cable provided by the utility model is not more than 3mm, and is at least less than 1/2 of the external diameter of the normal indoor optical cable, so that the space occupied by the optical cable which is laid can be reduced, and under the condition of small mounting space, the requirement of multi-core optical fiber connection between an optical fiber cross-connecting box and an optical transmission device and in an optical cable cross-connecting box is satisfied.
Description
Technical field
The utility model relates to a kind of unit optical cable.
Background technology
Along with the FTTX engineering based on the broadband light tranmission techniques is carried forward vigorously; Need a large amount of laying optical cable of installing between fiber cable cross connection box and optical transmission equipment and in the fiber cable cross connection box; To lay the space very limited and the optical cable that can provide between fiber cable cross connection box inside and fiber cable cross connection box and the optical transmission equipment is installed; When the general room optical cable reaches 12 cores at fiber number; Its external diameter is at least 6mm, lays the general room optical cable if install, and the space is laid in existing installation can not install so optical cable of multicore number.
The utility model content
The technical matters that the utility model will solve is: overcome the deficiency of prior art, a kind of unit optical cable be provided, satisfy under little installing space condition between the fiber cable cross connection box and optical transmission equipment and in the fiber cable cross connection box multicore count optical fiber and be connected.
The utility model solves the technical scheme that its technical matters adopted: a kind of unit optical cable; Has the fiber unit that is surrounded by optical fiber; It is the microtubule of 1.5mm that the sleeve pipe of described fiber unit adopts external diameter; Pack into the structure of optical fiber of integrated 12 optical fiber of packing in the sleeve pipe of described fiber unit, the sleeve pipe of described fiber unit adopts pine cover protection structure.
Further, described fiber unit is surrounded by protective sleeve outward, is filled with the filling protective between described fiber unit and the protective sleeve.
Further, the sleeve pipe of described fiber unit adopts the ultra-violet curing acrylic materials, is filled with waterproofing unction in the sleeve pipe of described fiber unit.Guarantee that optical fiber can be free movable in microtubule.
Further, described filling protective adopts the aramid fiber material.Make the unit optical cable have than high-tensile and fracture strength.
Further, described protective sleeve adopts the halogen-free polyolefin material.Laying when using in indoor installation can fire-retardant anti-baked wheaten cake, can satisfy between fiber cable cross connection box and the optical transmission equipment and fiber cable cross connection box in laid condition to the requirement of optical cable fire resistance.
The beneficial effect of the utility model is: the utility model is under the condition of same light fibre core number; The cable outer diameter of the utility model is no more than 3mm; Its external diameter is than extremely when young 1 times on general room optical cable; Thereby shared space in the time of can reducing fiber cable laying and install, satisfy under little installing space condition between the fiber cable cross connection box and optical transmission equipment and in the fiber cable cross connection box multicore count optical fiber and be connected.
