How are cables laid under the sea?
Submarine cables are laid down by using specially-modified ships that carry the submarine cable on board and slowly lay it out on the seabed as per the plans given by the cable operator. The ships can carry with them up to 2,000km-length of cable. Newer ships and ploughs now do about 200km of cable laying per day.
