Compression-resistant optical cable

The invention belongs to the field of optical cables, and particularly relates to a compression-resistant optical cable. The cable comprises an inner core wire, a functional protection layer, a pressure-resistant buffer layer and a sheath layer which are sequentially arranged from inside to outside. The functional protection layer wraps the outer surface of the inner core wire, the pressure-resistant buffer layer wraps the functional protection layer, the sheath layer wraps the outer surface of the pressure-resistant buffer layer, the pressure-resistant buffer layer comprises an outer buffer layer and an inner buffer layer, the inner surface of the outer buffer layer is provided with clamping teeth protruding inwards, tooth grooves in interference fit with the ends of the clamping teeth are formed in the outer surface of the inner buffer layer, and a deformation groove is formed between every two adjacent tooth grooves. The compression resistance of the optical cable can be effectively improved; blocking of p
