Description

TECHNICAL FIELD

[0002] With the rapid development of the communication industry, the use of optical fiber cables is increasing. Since the laying of optical cables is usually in the form of overhead, pipeline or underground structure, regardless of the method, the operator needs to pay relevant rental fees. The thicker the diameter of the optical cable, the larger the space required, and the higher the rental cost. Therefore, there is an increasing demand for optical cables with higher fiber core density.

[0003] CN111667950A discloses a layered distribution of optical cable, with a central reinforcing member, a light guide component, and a conductive component. The conductive component is composed of a conductive body and an insulating layer. It is characterized by having an outer overhead component composed of an outer sleeve body and an outer overhead body. One end of the outer overhead body is connected to the outer edge of the central reinforcing member, and the other end is connected to the outer sleeve body. The outer sleeve body has a cavity inside, and the light guide component is located in the cavity. Both sides of the outer overhead body of the outer overhead component have a receiving groove. The positions of the receiving grooves of adjacent outer overhead components correspond, and a part of the conductive component is located in the receiving groove of the adjacent outer overhead component. The adjacent outer overhead components hold the conductive component in the receiving groove. By layering, the density of the optical fibers in the optical cable is increased. The inner sleeve body is held by the receiving grooves on both sides of the outer overhead body. There is a large gap between the inner and outer overhead bodies, which actually reduces the space utilization.

[0004] CN114325989A discloses a high-temperature-resistant optical cable and its production process. The optical cable includes a coating layer, a cladding layer, and a core layer arranged from the outside to the inside. A heat dissipation structure layer is arranged between the coating layer and the cladding layer. The heat dissipation structure layer includes a plurality of heat dissipation sheets. Each heat dissipation sheet has a groove on the inner surface of the coating layer and the outer surface of the cladding layer. The grooves are filled with structural glue. The core layer includes a support framework with a through hole for inserting an optical fiber core in the center. The support framework has support ribs extending from its outer surface. Each support rib is connected to the inner surface of the cladding layer, and there is a clamping gap between adjacent support ribs. The optical cable uses the support framework and the heat dissipation sheets to form an inner and outer layer support, greatly improving the toughness of the optical cable. The heat generated inside the optical fiber core is conducted to the outside of the optical cable through the heat dissipation sheets, accelerating the heat dissipation inside the optical cable. It is used for heat resistance of optical cable.

[0005] CN114496361A discloses a high-density optical and electrical hybrid cable for data center, comprising a skeleton, a cable core and a clamping layer, the skeleton has an axial through hole in the center, a conductive wire is arranged in the through hole, a plurality of outward radiating support ribs are uniformly arranged in the circumference, and a containing cavity is formed between two adjacent support ribs; the cable core comprises an optical fiber ribbon and a sheath extruded outside the optical fiber ribbon, and is arranged in the containing cavity; the optical fiber ribbon is formed by a plurality of optical fibers; the clamping layer is formed by a plurality of guard plates connected with each other, one end of the guard plate forms a protruding tenon part, the other end forms a mortise part matched with the tenon part, the tenon part of each guard plate is adaptively clamped with the mortise part of the adjacent guard plate, and the clamping layer is arranged outside the skeleton and the cable core. The clamping layer is combined and separated through the mortise and tenon structure; the combination of the sheath and the support rib is realized by the cooperation of the recesses on the left and right sides of the support rib and the protrusions on the left and right sides of the sheath, and the combination of the sheath and the support rib is realized by the combination of the recesses on the left and right sides of the support rib and the protrusions on the left and right sides of the sheath. However, the recesses make the strength of the support rib smaller or weaker, and accurate dimensions are required, whether the position of the protrusion and the position of the recess, which brings trouble to manufacturing, and the protrusion and the recess are only weakly matched, and the smooth arc surface contact between them, after the guard plate is removed or lost due to some reason, the sheath is easy to separate from the recess, causing the instability of the product, and the components between the guard plate and the support rib also cause the structure to be not compact, and the fiber core density has further space for improvement.
