How to make a light-weight electro/optical umbilical?

The newly developed Sonic Wireline Operated Remote Drill (SWORD) is a system designed to collect samples and geotechnical data from the seabed. The cable needs to combine electro/optic components with a high tensile light-weight strength member, taking into account the rules around rope hoisting/lifting applications. 

Where conventional steel would be too heavy to cope with the system requirements, the optimal configured strength-member is able to withstand the high tension, at a lower self-weight. This white paper explains how De Regt designed, manufactured and tested a unique cable solution with a strength member made of 8 (!) layers of aramid wires. This is a world-first.
