Submarine communications cables

  • Recent tensions in the Red Sea region highlight concerns over the security of undersea cable systems connecting India to global telecommunications networks. 

What are undersea cables and why are they Important? 

  • Submarine communications cables are essential infrastructure laid on the seabed to enable the transmission of telecommunication signals between land-based stations across oceans and seas. These cables utilize advanced Fiber-optic technology, where optical fibers are protected by marine-grade coatings, ensuring durability in harsh underwater conditions

  • Global Connectivity: These cables play a crucial role 

  • in connecting continents worldwide, forming a global network of communication. Strategically positioned along the ocean floor, submarine cables serve as vital links, facilitating the seamless exchange of telecommunications data across vast distances. 

  • Compared to satellite alternatives, submarine cables offer a reliable, cost-effective, and high-capacity solution for internet connectivity. This makes them the preferred choice for global communication networks, enabling efficient data transmission on a massive scale.

  • They are installed through a meticulous process involving cable station setup, installation, and laying, with specialized ships and equipment.

  • India’s Critical Infrastructure: Submarine cables are integral to India’s flagship initiative, Digital India 2015, which aims to digitally empower society and governance. With 17 submarine cables landing in different parts of the country, India is emerging as a significant hub for submarine cable infrastructure.

  • Submarine Communications Cables: Used for communication and internet connectivity.

  • Submarine Power Cables: Transmit power from one place to another 

India’s Submarine Cable Infrastructure

  • India has significantly expanded its undersea connectivity, with 17 submarine cables landing at 14 cable landing stations, primarily located in Mumbai and Chennai.
