Abstract
The invention belongs to the technical field of optical cables and discloses a complete-dry type optical cable. The complete-dry type optical cable comprises sheaths, optical fiber units, central reinforcing parts, cushion layers, water resistance yarns and optical fibers. The optical fibers are composed of 6 optical fiber units, and the sheaths are sleeved on the externals of the optical fibers. The independent sheaths are sleeved on the externals of the optical fiber units, and the water resistance yarns and the optical fibers are arranged inside the optical fiber units. The central reinforcing parts are arranged at the centers of the 6 optical fiber units and provided with the cushion layers. The independent sheaths are sleeved on the external of each optical fiber unit of the complete-dry type optical cable respectively. In addition, a sheath is also sleeved outside a whole structure formed by the 6 optical fiber units, protection of the optical fibers is strengthened, the optical fibers are composed of 6 independent optical fiber units, the optical cable is not easily damaged in use, the service life is prolonged, and construction is facilitated.
Description
Technical field
The invention belongs to the optical cable technology field, relate in particular to a kind of Full-dry optical cable.
Background technology
At present, communication cable tubing scarcity of resources, the engineering construction difficulty, the demand for development optical cable construction of Access Network can be flexible.Because conventional optical cable exists that the cable footpath is thick, deadweight more greatly, not flexible coiling, and large in city excavation pipeline laying difficulty, construction is deployed troops on garrison duty loaded down with trivial details, the engineering time is long, the high difficulty of expense.
?
Summary of the invention
The object of the present invention is to provide a kind of Full-dry optical cable, be intended to solve that optical cable exists that the cable footpath is thick, deadweight more greatly, not flexible coiling, and large in city excavation pipeline laying difficulty, construction is deployed troops on garrison duty loaded down with trivial details, the engineering time is long, the high difficulty of expense.
The object of the present invention is to provide a kind of Full-dry optical cable, this Full-dry optical cable comprises: sheath, fiber unit, central reinforce member, water blocking yarn, optical fiber.
Fiber unit all overlaps and independent sheath is arranged, fiber unit internal placement water blocking yarn and optical fiber outward; Optical cable also overlaps sheath is arranged outward, and reinforcement is arranged in the center of optical cable.Reinforcement center arrangement bed course.
Further, described optical cable is comprised of 6 fiber units.
Further, described central reinforce member center arrangement bed course.
Full-dry optical cable of the present invention; the cable footpath is less; easily crooked coiling; corrosion-resistant; block-water effect is good, and the life-span is long, constructability; by cover outside each fiber unit of optical cable, independent sheath is arranged; the one-piece construction be comprised of 6 fiber units is in addition also overlapped sheath is arranged outward, has strengthened the protection of optical fiber, and optical cable is comprised of 6 independent fiber units; not fragile in use; life-span is increased, constructability, and also the thinner reinforcement of the center arrangement of 6 fiber units replaces being enclosed within the past outer field stainless-steel tube; weight reduction, flexible.
The accompanying drawing explanation
Fig. 1 is the cross sectional representation of Full-dry optical cable of the present invention.
Fig. 2 is the cross sectional representation of the fiber unit of Full-dry optical cable of the present invention.
In figure: 1, sheath; 2, fiber unit; 3, central reinforce member; 4, bed course; 5, water blocking yarn; 6, optical fiber.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1-2 shows the structure of the Full-dry optical cable that the embodiment of the present invention provides.Only show for convenience of explanation part related to the present invention.
Outer all the overlapping of fiber unit 2 has independent sheath 1, fiber unit 2 internal placement water blocking yarns 5 and optical fiber 6; The one-piece construction of 6 fiber unit 2 compositions is also overlapped the center that 1,6 fiber unit 2 of sheath is arranged outward and is arranged reinforcement 3, reinforcement center arrangement bed course 4.
Outer all the overlapping of fiber unit 2 has independent sheath 1; The one-piece construction of 6 fiber unit 2 compositions is also overlapped the center that 1,6 fiber unit 2 of sheath is arranged outward and is arranged thinner reinforcement 3.
The Full-dry optical cable of the present invention's design, the cable footpath is less, easily crooked coiling, corrosion-resistant, block-water effect is good, and the life-span is long, constructability.
By cover outside each fiber unit of optical cable, independent sheath is arranged; the one-piece construction be comprised of 6 fiber units is in addition also overlapped sheath is arranged outward; strengthened the protection of optical fiber; optical cable is comprised of 6 independent fiber units, not fragile in use, and the life-span is increased; constructability; and the thinner reinforcement of the center arrangement of 6 fiber units replaces being enclosed within the past outer field stainless-steel tube, weight reduction, flexible.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
