Abstract
According to the opto-electro hybrid cable of the invention, it is possible to prevent the excessive lateral pressure from being applied to the optical fibers from the electronic wires and the excessive bending or twisting from being generated. In addition, it is possible to increase the tensile strength and to prevent the excessive tension from being applied to the optical fibers, so that it is possible to keep the favorable transmission characteristics.
