the conductive wires 300 are all metal wires, have good mechanical properties, and are far better than the optical fiber wires 400 in torsion resistance and compression resistance, so that the conductive wires 300 are not easy to damage when being pressed, and can be used as a 'sacrificial element' to protect the optical fiber wires 400.
In a still further aspect of the present invention,
a hollow elastic tube 500 arranged along the axial direction of the optical cable is filled in the cavity between the inner sheath 200 and the outer sheath 100;
as shown in fig. 4, the hollow elastic tube 500 is provided to increase the pressure-resistant threshold of the optical cable, because the inner sheath 200 may touch the outer surface of the hollow elastic tube 500 during the twisting process, which causes the deformation and displacement of the hollow elastic tube 500 to further generate the buffering effect.
