Optical fiber ribbon optical cable with foldable component

The invention belongs to the field of optical cables, and discloses an optical fiber ribbon optical cable with foldable parts, which is provided with a plurality of optical fiber ribbons (2) and an outer sheath (5), and is characterized in that the optical fiber ribbon optical cable is also provided with two same folding parts (1), each folding part is composed of a first folding section, a second folding section, a third folding section, a fourth folding section and a seventh folding section which are sequentially connected together, and a folding groove (10) is formed between every two adjacent folding sections. The adjacent folding sections can be bent relatively, each folding section is internally provided with an accommodating hole, the optical fiber ribbon is positioned in the accommodating hole, and the lower surfaces of the fourth folding section and the fifth folding section of the two folding parts are oppositely arranged respectively; each folding part is bent into two square structures and an inne
