How underwater cables join the planet's continentsThe seabed off Crete is prepared for your laying of an undersea fibre-optic cable.
In contrast to an aerial cable, a buried cable invariably makes use of commercially pure copper or aluminum (mechanical power just isn't a difficulty underground), along with the stranded conductor is usually rolled To maximise its compactness and electrical conductance.
Cables product of optical fibres 1st came into operation during the mid-seventies. In a fibre-optic cable, gentle signals are transmitted by thin fibres of plastic or glass from light-weight-emitting diodes or semiconductor lasers by way of interior reflection.
The cable core incorporates an individual solid or stranded central energy element that is certainly surrounded by optical fibres; they are both organized loosely within a rigid Main tube or packed tightly into a cushioned, versatile outer jacket.
