ABSTRACT:
In a submarine optical cable for unrepeatered links the conventional wire armouring is replaced by a metal tape (7), the central strength member (4) providing the main tensile strength in the armoured cable. The advantage is lower cost, increased torsional stiffness and reduced cable diameter. Typically the tape (7) is corrugated to enhance the flexibility of the cable.
