Abstract
A ground wire with optical fibers is disclosed. The ground wire includes twisted optical modules in the form of plastic tubes that accommodate freely placed optical fibers and water-blocking gel, wherein water-blocking tape applied to twisted optical modules, which are enclosed in a steel tube, coated with an aluminum sheath. The aluminum sheath is helically wrapped with lays of wire. The technical result is provided by increased air tightness of the optical core and permissible crushing stresses.
