SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is: the microbeam-type indoor optical cable for the data center solves the problems that the microbeam-type indoor optical cable is weak in bending resistance and easy in information transmission efficiency.
The technical scheme of the utility model is that: a micro-beam tube type indoor optical cable for a data center includes: oversheath, aramid yarn, microbeam pipe, colored optic fibre.
The colored optical fiber is single mode optical fiber (G652, G655, G657, etc.) or multimode optical fiber (OM 1, OM2, OM3, OM4, OM5, etc.).
The plurality of colored optical fibers are arranged into a bundle structure with a polygonal cross section, and a sleeve-shaped reinforcing piece is coated on the outer side of the bundle structure to form a cylindrical cable bundle. The reinforcing member can increase the tight packing effect of the colored optical fiber, and avoid the existence of gaps among the arrangements, thereby improving the bending resistance.
The beam-shaped structure is a base unit with a regular triangle section formed by three colored optical fibers which are tangentially arranged, and the base unit is in a stable compression structure. The inner wall of the reinforcing part is provided with a convex valve, and the end part of the valve is abutted against the base unit to divide the section of the beam-shaped structure into three equal-divided areas. The valve has two effects, and one of them is carried out the structure and is divided the district, not only can play the rational arrangement effect to arranging of single core, can also play the atress buffering effect between two adjacent districts simultaneously on can dividing the every colored optic fibre of distributing the atress evenly in the district moreover.
Three colored optical fibers are arranged in each equal division area, a raised structure surface is arranged on the inner wall of each equal division area, and the structure is tightly abutted against the colored optical fibers in the equal division area in the direction facing the basic unit. The structural surface not only can increase the packing degree of the beam-shaped cross section, but also can improve the stress capacity in three directions and can play an internal damping effect.
The micro-beam tube is sleeved outside the reinforcing part and tightly wraps the optical fibers, so that the relative positions of the optical fibers are solidified, and the relative position change of the optical fibers is avoided. Moreover, the thickness of the micro-beam tube layer is thinner, so that the micro-beam tube layer can be conveniently stripped. The microbeam material is generally made of LSZH material or other soft plastics, and is mainly made of soft material (generally, Shore A hardness is 85-90), so that the optical fiber can be protected from being extruded, and the optical fiber can be easily peeled off by hand.
Aramid yarns are uniformly bundled and covered on the outer side of the microbeam tube, and the aramid yarns can adopt various covering directions to increase the weaving strength. The aramid yarn is externally bound with an outer sheath, and the outer sheath is usually made of LSZH material, and can also be made of other materials such as PVC, flame-retardant PE and the like.
Preferably, the bundle structure is formed by arranging a plurality of colored optical fibers having the same radial dimension.
Preferably, the colored fibers on both sides of the bisected region are abutted against the respective valves on one side, thereby reducing the gap and improving the resistance to compression and bending.
Preferably, the middle colored fiber in the bisecting region remains in interference with the structured surface, thereby reducing the gap and increasing the resistance to compression and bending.
The utility model has the advantages that: in the structure of the microbeam-type indoor optical cable for the data center, the relative positions of a plurality of optical fibers are set at first, and then the optical fibers are tightly wrapped by the microbeam tube, so that the relative positions of the optical fibers can be solidified, the relative position change of the optical fibers is avoided, and the stable performance of the optical fibers in use is ensured.
