Submarine cables are primarily used for long-distance
communication, connecting different continents and countries. They
enable the transmission of large volumes of data, including
internet traffic, telephone calls, and other forms of
telecommunications.
Construction: Submarine cables are constructed with multiple layers
of protective materials to ensure their durability and performance
in the harsh marine environment. The typical construction includes
a conductor, insulation, metallic shielding, and an outer
protective sheath.
Transmission Capacity: Submarine cables are capable of carrying
large amounts of data or electrical power. They have high
transmission capacities, often measured in terabits per second
(Tbps) for data cables and gigawatts (GW) for power cables.
