Submarine telecommunication cables are essential for global connectivity. They carry about 99% of internet traffic and support critical services. However, these cables face vulnerabilities from various threats. The International Telecommunication Union (ITU) and the International Cable Protection Committee (ICPC) have established the International Advisory Body for Submarine Cable Resilience. This initiative aims to enhance the resilience of submarine cables worldwide.
About Submarine Cables
Submarine cables link continents and facilitate global communication. More than 500 active and planned systems operate . These cables are designed to transmit large data volumes efficiently. They are protected by layers against environmental hazards and are optimised for high-speed data transmission.
Challenges Facing Submarine Cables
Submarine cables are prone to damage. Factors include fishing activities, anchoring, and natural hazards. Each year, 150 to 200 faults occur globally. In 2023 alone, over 200 repairs were reported. Such disruptions can lead to economic instability and internet access issues.
Role of the International Advisory Body
The International Advisory Body comprises 40 representatives from various countries. It will meet bi-annually to discuss policies and best practices. The body aims to promote resilience and mitigate risks associated with submarine cables. Members will share strategies to address increasing traffic and environmental threats.
India’s Contribution
India plays role in the global submarine cable network. The country hosts around 17 international cables across 14 landing stations. Major telecom operators include Tata Communications, Reliance Jio, and Bharti Airtel. These operators ensure robust connectivity and support for global communication.
Future Directions
The Advisory Body will provide strategic guidance on improving cable resilience. It will focus on damage prevention, rapid recovery, and sustainable practices. The inaugural meeting is set for December 2024, followed by a physical summit in Nigeria in February 2025.
Importance of the ITU
The ITU is very important in enhancing submarine cable resilience. As a UN agency for digital technologies, it develops best practices for securing these infrastructures. The ITU’s efforts include standard-setting and technical guidance for maintaining and protecting submarine cables.
Conclusion
Submarine cables are vital for the global digital economy. Their resilience is critical for maintaining connectivity and supporting essential services. Ongoing international cooperation will be key to addressing the challenges they face.
