The invention belongs to the technical field of optical fiber communication, and discloses an optical fiber ribbon optical cable, which is provided with a skeleton component, a plurality of main optical fiber ribbons and a protection layer, and is characterized in that the skeleton component is composed of a skeleton body and a plurality of skeleton blades distributed outside the skeleton body, a concave skeleton groove is formed between adjacent skeleton blades, the skeleton component is of an integrated structure, the protection layer is composed of an annular column-shaped protection layer body and a plurality of groups of accommodating components which protrude inwards from the inner wall of the protection layer body, each group of accommodating components is composed of a first isolation component, a second isolation component and at least one third isolation component, at least one main optical fiber ribbon with a coating layer is arranged in each isolation groove, and the protection layer body is located outside the main optical fiber ribbon. The optical fiber ribbon optical cable has the main beneficial effects that the product diameter is smaller, the material consumption is lower, the cost is lower, the fiber core density is higher, and the optical fiber ribbon is more convenient, quicker and easier to take and place.
