Optical fiber ribbon optical cable with octahedral cylinder structure shell

Abstract

The invention belongs to the technical field of optical cables and discloses an optical fiber ribbon optical cable with an octahedral cylinder structure shell. The optical fiber ribbon optical cable is provided with a central optical fiber ribbon body and a shell (4), wherein the central optical fiber ribbon body is composed of a plurality of central optical fiber ribbons (1); the optical cable is characterized in that the shell (4) is of an octahedral cylinder structure, and a shell inner cavity (45) is formed in the shell (4); the optical cable further comprises four isolation components (5), the isolation components (5) are located in an inner cavity (45) of the shell, first to fourth containing cavities are formed between the isolation components (5) and the shell (4), a central containing cavity (40) is formed among the isolation components (5), the central optical fiber ribbons are located in the central containing cavity (40), and at least one of the first to fourth containing cavities is internally provided with an external optical fiber ribbon (7). The optical cable is advantaged in that the optical cable has characteristics of convenient stripping of the electrical unit and the optical fiber ribbon, high fiber core density, high space utilization rate, good compression resistance and the like, and can better adapt to the width and height of the optical fiber ribbon body.

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 ...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned prior art does not give the technical inspiration of how to make the fiber core of the optical fiber ribbon have a higher density, which is easier to combine with the electric unit and does not make the electric heating affect the light transmission, and it does not give how to make the existing technology such as YD The use of rectangular optical fiber ribbons commonly used in / T981 and more reasonable use of space and other technical inspirations
