The utility model discloses a butterfly-shaped compression-resistant stretch-resistant communication optical cable, which comprises a butterfly-shaped low-smoke halogen-free sheath, a supporting pipe fitting is arranged in the butterfly-shaped low-smoke halogen-free sheath, a supporting inner pipe, a supporting outer pipe and a plurality of supporting strips are arranged on the inner side of the supporting pipe fitting, a plurality of communication optical fibers are arranged in the supporting inner pipe, and the supporting strips are arranged in the supporting outer pipe. The butterfly-shaped low-smoke halogen-free sheath is provided with a plurality of tensile assemblies. Buffering energy absorption is provided through deformation of the stress holes, the lightening holes and the buffering holes, pressure directly acting on the supporting pipe fitting is reduced, meanwhile, further buffering energy absorption is carried out through deformation of the supporting outer pipe and the supporting inner pipe, supp
