Submarine cables installed on the ocean floor facilitate the transmission of data and voice between land-based stations.
International communication has relied on submarine cables since the first one was laid across the English Channel in 1850. This cable was used to transmit telegraph messages between England and France.
Using fiber-optic cables for telecommunications has proven to be a superior option compared to satellite-based alternatives. These cables are not only faster and more reliable but also more cost-effective.
They consist of thin strands of glass that transmit data as light pulses encased in layers of plastic, steel wires, copper sheathing, and polyethylene insulation.
Reports indicate that there will be a significant rise in traffic, with a projected compound annual growth rate of approximately 28% from 2022 to 2030, resulting in a monthly data consumption of 603.5 million terabytes.

Expansion Poses Cyber Security Risks
A report by Recordfuture states that Chinese state-owned enterprises have been striving for a larger share in the global submarine cable network since the beginning of the 21st century.
China is currently increasing its ownership and operation of cables around the globe, which gives them more control over the deployment of submarine cables in specific locations.
