A ribbon fiber optic cable, comprising a cable core, a water blocking layer (4), a steel tape (5) and an outer jacket (6) which are sequentially arranged from inside to outside. The cable core comprises a flexible foamed subunit (1) and tight-buffered subunits. Each tight-buffered subunit comprises a TPU loose tube (2) and optical fiber ribbons (3). A gap is formed between the water blocking layer (4) and the steel tape (5). By using the TPU loose tubes (2), due to a tight-buffered thin-wall structure, the tight-buffered subunits have a small size, thereby increasing the space utilization of optical fibers in the loose tubes and the fiber packing density of optical fibers in the fiber optic cable, and achieving a large core diameter ratio. The cable core uses the flexible foamed subunit (1), and when the tight-buffered subunits and the flexible foamed subunit (1) are stranded, the flexible foamed subunit (1) made of a soft material provides protection for the tight-buffered subunits when the fiber optic cable is in use, thereby ensuring the transmission performance of the fiber optic cable. A gap is formed between the water blocking layer (4) and the steel tape (5), so that there is certain spacing inside the fiber optic cable, and a loose structure is achieved, reducing the impact of outer jacket shrinkage of the fiber optic cable on the TPU loose tube (2) and the optical fiber ribbons (3), and solving the problem of additional fiber attenuation during loose coiling and thermal cycling of the fiber optic cable.
