Optical fiber ribbon optical cable with elastic wrapping cloth outer protective layer

Abstract

The invention belongs to the field of cables, and particularly relates to an optical fiber ribbon optical cable with an elastic wrapping outer protective layer, which is provided with an outer protective layer, a cable core and optical fiber ribbons, and is characterized in that the cable core is composed of a cable core main body, a plurality of open fiber accommodating grooves are formed around the outer edge of the cable core main body, and the optical fiber ribbons are arranged in the fiber accommodating grooves; a clamping groove is formed between every two adjacent fiber containing grooves, an outer protection layer containing cavity is formed in the cable core body, and the outer protection layer containing cavity is outwards provided with a cloth outlet channel. The outer protection layer is composed of an outer protection layer body, a limiting rod and a cloth shaft, the outer protection layer body is wound on the cloth shaft, the two ends of the outer protection layer body are connected with the cloth shaft and the side wall of the limiting rod respectively, the outer protection layer body penetrates through the cloth outlet channel, the outer diameter of the limiting rod is smaller than that of the clamping groove, and the outer diameter of the cloth shaft and the outer diameter of the limiting rod are larger than the width of the cloth outlet channel. The optical cable has the advantages of being convenient to construct, adjustable in thickness of the optical cable outer sheath, energy-saving, environment-friendly, capable of being connected without using a junction box, good in mechanical performance and the like.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to an optical fiber ribbon cable with an outer sheath covered with elastic cloth. Background technique [0002] Optical fiber ribbon cables are generally large-core optical cables, which are widely used in backbone networks and intercity networks. Every year, operators have to purchase tens of millions of core-kilometers of optical fiber ribbon cables. [0003] In the prior art, such as CN213876121U discloses a skeleton core structure and a skeleton type optical cable. The skeleton core structure includes a skeleton, and the skeleton is formed with a plurality of first skeleton grooves and a plurality of second skeleton grooves in a radial direction extending along its edge to the center, each of the first skeleton grooves is connected with each of the The second skeleton grooves are arranged at intervals, and the width of each of the first skeleton grooves is the same as that of ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art has the following disadvantages: when the optical fiber ribbon is used, the outer sheath and the inner sheath must be destroyed; after the optical fiber in the optical cable is welded, a special junction box is required to fix it, which is costly and inconvenient; Extruded, cannot be added later; fiber optic ribbon cannot be replaced during later maintenance
