The utility model relates to the technical field of data transmission optical cables, in particular to a big data transmission optical cable resistant to radial pressure. A radial pressure resistant big data transmission optical cable comprises a central reinforcing core, a reinforcing core sleeve, a radial pressure resistant protective layer, an optical fiber cable, a water blocking layer and anouter protective sleeve. The radial pressure resistant protective layer is composed of a radial pressure resistant protective inner layer and a radial pressure resistant protective outer layer, the radial pressure resistant protective inner layer is of a tubular structure and is located on the outer layer of the reinforced core sleeve, star-shaped holes are evenly distributed in the outer side wall of the radial pressure resistant protective inner layer, and the radial pressure resistant protective outer layer is of a tubular structure and is located on the outer side of the radial pressure resistant protective inner layer. The anti-radial-pressure protection inner layer and the anti-radial-pressure protection outer layer can be hardened instantaneously when the optical cable is subjectedto radial impact, the radial impact force is resisted, and meanwhile, the porous structure of the anti-radial-pressure protection inner layer can play a role in absorbing energy and relieving impact force.
