How underwater cables hook up the whole world's continentsThe seabed off Crete is prepared to the laying of an undersea fibre-optic cable.
Compared with an aerial cable, a buried cable invariably makes use of commercially pure copper or aluminum (mechanical toughness is not really a difficulty underground), plus the stranded conductor is frequently rolled To optimize its compactness and electrical conductance.
Cables made of optical fibres 1st came into Procedure in the mid-seventies. Within a fibre-optic cable, light-weight signals are transmitted as a result of skinny fibres of plastic or glass from light-weight-emitting diodes or semiconductor lasers by way of inside reflection.
The cable core is made up of a single reliable or stranded central strength factor that may be surrounded by optical fibres; they're possibly arranged loosely within a rigid Main tube or packed tightly into a cushioned, versatile outer jacket.
