Abstract

The invention belongs to the technical field of optical cables, and discloses an optical fiber ribbon optical cable with an octahedral cylindrical shell structure, which has a central optical fiber ribbon body and an outer shell (4), and the central optical fiber ribbon body is composed of a plurality of central optical fiber ribbons (1); It is characterized in that the shell (4) is an octahedron structure, and a shell cavity (45) is formed inside the shell (4); it also has four isolation parts (5), and the isolation parts (5) are located in the shell cavity (45) Inside, the first to fourth cavities are formed between the isolation component (5) and the outer shell (4), and a central cavity (40) is formed between the isolation components (5), and the central optical fiber ribbon is located in the central cavity (40) , at least one of the first to fourth cavities has an external optical fiber ribbon body (7). The invention has the beneficial effects of convenient stripping of the electrical unit, convenient stripping of the optical fiber ribbon, high fiber core density, high space utilization, better adaptation to the width and height of the optical fiber ribbon body, and good compression resistance.

Description

technical field [0001] The invention belongs to the technical field of optical cables, and in particular relates to an optical fiber ribbon optical cable with an octahedral cylindrical shell. Background technique [0002] With the in-depth development of the national communication network construction, the central tube ribbon cable is widely used as a commonly used cable. In the existing technology, the industry standard YD / T981.2-2009 "Optical Fiber Ribbon Cable for Access Network Part 2: The GYDXTW optical cable in the central tube type has a loose tube, a water-blocking layer outside the loose tube, an armored layer outside the water-blocking layer, and an outer sheath extruded outside the armored layer. The outer sheath There is still a reinforcement in the layer, and when it is necessary to transmit electrical signals, the signal line is also located in the outer sheath. [0003] The above prior art has the following shortcomings: 1. The electrical unit is not easy to ...
