  Telecommunications cable - Patent 5563377
A telecommunications cable having a cable core in which each conductor is surrounded by an individual dual layer insulation of an inner layer of flame retardant polyolefin and an outer layer of fluorinated ethylene propylene.
In preferred cables, the fluorinated ethylene propylene layer has a minimum thickness of 2 mil to afford the required protection, the remainder of the insulated thickness being provided by the flame retardant polyolefin to produce the required electrical characteristics to the cable.
Surprisingly, although the flame retardant polyethylene conventionally is avoided for plenum cable constructions, in the invention and as shown by the embodiment it was shown that material is suitable as the inner layer insulation for plenum cables.

 Porthcurno Telegraph Museum - The Great Cable Layer
The cable was believed to lie 1 mile down on the seabed, but even so, the decision was made to attempt to grapnel for the cable.
It took another 3 days to hook the cable and by then most onboard could not bear the suspense and retreated to the Grand Saloon to drown the sound of the winch gear out with the pianoforte and to calm their nerves with stiff brandy.
With sore heads, the crew fastened the cable to the buoy and the Great Eastern then ran full steam to the UK to complete the task started a year earlier.
