I suppose it would, I guess I'm just wondering for how long fiber cables have been the standard, and if there are any operational cables from the time before that. I'm pretty sure there are plenty of cables dedicated for one purpose (e.g. electricity only) that do not contain fiber simply because there wasn't a need or requirement when it was planned. edit: Here's an example: > The world record from 1994, for the longest HVDC cable with the highest capacity, was equalled in 2000 with the successful completion of the Swedish-Polish HVDC transmission link between Sweden and Poland: > 1. Stretching over 250 km, it is one of the two longest submarine HVDC cables ever laid. > 2. At 600 MW, the cable is one of the most powerful HVDC cables in commercial operation. > 3. At 450 kV DC, this cable together with the cable between Sweden and Germany, has the highest voltage rating of all existing submarine HVDC cables. This cable doesn't seem to have any other purpose than transferring electricity, and it was installed "only" 21 years ago.
