ABSTRACT:
In a method for producing an optical cable (1), at least one optical fiber (3), is surrounded by an extruded tubular sheath (5) which comprises an inner layer (7) and an outer layer (9) and is produced in a single operational step. Tension elements (11, 11') are embedded in the tubular sheath (5) for increasing the tensile strength of the tubular sheath (5). The optical cable made by the method of the invention is particularly suited for applications as an indoor cable and as a non-self-supporting cable for installation on ground wires or phase wires of high voltage transmission lines.
