Abstract
The invention discloses a small dry optical cable which comprises optical fiber, a plurality of reinforcing members, water retaining powder and an outer jacket, wherein the optical fiber and the reinforcing members paved in parallel in a staggered manner are wrapped by the outer jacket. The gaps between the optical fiber and the reinforcing members are filled by the water retaining powder. Through above manner, the optical cable disclosed by the invention is less in diameter, lighter in weight, free from pollution due to full dryness, and more convenient to arrange continuously. The optical cable is convenient for construction, the cost of consumables is lowered, the loss of joints is reduced and the reliability is improved.
Description
Technical field
The present invention relates to cable and optical cable and make the field, particularly relate to a kind of small-sized dry fiber optic cables.
Background technology
Optical distribution cable is still used conventional GYTA or GYTS type optical cable in user building leading in cable in the existing fiber Access Network and the building, and this optic cable diameter is big, Heavy Weight, to take installing space big; Contain a large amount of ointment in the optical fiber loose tube of existing GYTA or GYTS type optical cable and the cable core, make troubles to constructing operation, also contaminated environment.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of small-sized dry fiber optic cables, and its diameter is littler, weight is lighter, dry type is pollution-free, lay continue more convenient; Can convenient construction, reduce consumables cost, reduce the light splicing loss, improve reliability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of small-sized dry fiber optic cables is provided, this small-sized dry fiber optic cables comprises multifiber, several reinforcement, water-proofing powder and oversheath, by the oversheath parcel, be filled with water-proofing powder in the gap between described multifiber and the several reinforcement after the staggered parallel laid of described multifiber and several reinforcement;
Preferably, described optical fiber is the painted bare fibre of bend-insensitive;
Preferably, described reinforcement is the aramid fiber yarn;
Preferably, described oversheath is low smoke halogen-free flame-retardant polyolefin (LSZH) plastics.
The invention has the beneficial effects as follows: a kind of small-sized dry fiber optic cables of the present invention, the diameter of this small-sized dry fiber optic cables has only about 40% (same 12 core optical cables of GYTA type, the about 9.5mm of the external diameter of GYTA type, and the external diameter of this small-sized optical cable 4mm only), reduced installing space greatly; The 2nd, there is not ointment in this optical cable, made things convenient for the operation that continues when installing, totally environmental protection again; The 3rd, there is not metal in this optical cable, in light weight soft again, not only lightning protection but also made things convenient for construction has also reduced network construction cost; Can reduce the light splicing loss, improve reliability.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of a kind of small-sized dry fiber optic cables of the present invention.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that the advantage of invention and feature can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of small-sized dry fiber optic cables, this small-sized dry fiber optic cables comprises painted bare fibre 1, several reinforcement 2, water-proofing powder 3 and the oversheath 4 of 1-12 root bend-insensitive, by oversheath 4 parcels, be filled with water-proofing powder 3 in the painted bare fibre 1 of described 1-12 root bend-insensitive and the gap between several reinforcement 2 after the painted bare fibre 1 of described 1-12 root bend-insensitive and the several reinforcement 2 staggered parallel laid; Described reinforcement 3 is the aramid fiber yarn; Described oversheath 4 is low smoke halogen-free flame-retardant polyolefin (LSZH) plastics.
A kind of small-sized dry fiber optic cables of the present invention, the diameter of this small-sized dry fiber optic cables have only about 40% (same 12 core optical cables, the about 9.5mm of the external diameter of GYTA type, and the external diameter of this small-sized optical cable 4mm only) of GYTA type, have reduced installing space greatly; The 2nd, there is not ointment in this optical cable, made things convenient for the operation that continues when installing, totally environmental protection again; The 3rd, there is not metal in this optical cable, in light weight soft again, not only lightning protection but also made things convenient for construction has also reduced network construction cost; Its diameter is littler, weight is lighter, dry type is pollution-free, lay continue more convenient; Can reduce the light splicing loss, improve reliability.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
