[0002] The increasing popularity of optical fiber transmission and the continuous development of data centers have put forward higher requirements for high-density and large-core-count optical cables. Especially in large-scale use environments such as comprehensive data centers, high-density and large-core-count optical cables are particularly important. Comprehensive data centers have a wide variety of equipment, a large number of external interfaces, which requires more transmission channels. As optical cables for indoor applications, space is one of the important factors that must be considered for laying. Therefore, increasing the density of optical fibers in a limited space is one of the most important goals.

[0003] It is not easy to achieve high density inside the optical cable in the prior art when laying, because there is less space inside the high density, so it is easy to cause damage to the optical fiber and the optical cable when subjected to pressure, thereby affecting the use and lacking protection.

This structure can realize high-density optical cable laying.

[0005] To achieve the above-mentioned purpose, a high-density fiber-optic ribbon-layer twisted optical cable is provided, comprising: an optical cable outer layer, a first optical fiber ribbon layer and a fiber core, a plurality of second optical cables are fixedly connected inside the optical cable outer layer, a wear-resistant layer is arranged on the inner side of the second optical cable, a plurality of optical fiber ribbon layers are arranged inside the wear-resistant layer, rubber support strips are fixedly connected between the optical fiber ribbon layers, a thermal insulation layer is fixedly connected on the inner side of the rubber support strip, a plurality of first optical cables are arranged inside the thermal insulation layer, and a fiber core is arranged inside the first optical cable.

[0006] According to the high-density optical fiber ribbon layer-stranded optical cable, a first buffer cavity is opened between the second optical cables.

[0007] According to the high-density optical fiber ribbon layer twisted optical cable, a second buffer cavity is opened between the optical fiber ribbon layers.

[0008] According to the high-density optical fiber ribbon layer-stranded optical cable, a waterproof layer is fixedly connected to the inside of the outer layer of the optical cable.

[0009] According to the high-density optical fiber ribbon layer-twisted optical cable, the rubber support strip is made of rubber material and has a long strip shape.

This structure can realize high-density optical cable laying, and the use efficiency is higher.

[0012] 2. The utility model is provided with a first buffer cavity, a second buffer cavity, an optical fiber ribbon layer and a rubber support strip. When the outer layer of the optical cable is buried underground or laid on an optical cable rack, the first buffer cavity and the second buffer cavity can provide a buffer space when squeezed by objects, and it is not easy to cause damage to the internal optical fiber ribbon layer and the first optical cable and the second optical cable. In addition, a rubber support strip is arranged between the optical fiber ribbon layers, and a buffer effect is provided by the rubber support strip. By laying high-density optical cables, a buffer space is reserved and the buffer effect is increased by the rubber support strip to protect the use.
