Black Sea Fiber-Optic Cable System
The Black Sea Fiber-Optic Cable System is a crucial component of the Black Sea Submarine Cable (BSSC) project. It will be laid alongside the electric cable, stretching 1,100 km underwater.
The fiber-optic cable aims to strengthen Internet connectivity between the Caucasus and the EU, significantly improving the region's digital infrastructure. This will have a positive impact on the local communities and businesses.
The fiber-optic cable component is expected to attract significant private-sector investment, which will help to make the project more financially sustainable.

Global Gateway Initiative
The Global Gateway initiative is a vital part of the Black Sea fiber-optic cable system. It's an effort by the European Commission to provide an alternative to China's Belt and Road initiative and Digital Silk Road initiative.
This initiative aims to offer developing countries an alternative to China's strategic funding for physical and digital infrastructure worldwide. It's a way to promote connectivity and economic growth in regions that might otherwise rely heavily on China.
The European Investment Bank has proposed a €20 million grant for the Black Sea cable project, which is currently in the feasibility assessment stage. This grant is a significant step towards making the project a reality.
The Global Gateway initiative is part of the European Commission's broader efforts to promote connectivity and economic growth in developing countries. It's a response to the growing need for reliable and secure internet connectivity worldwide.

Black Sea Submarine Cable
The Black Sea Submarine Cable project is an ambitious vision to establish parallel electricity and fiber-optic submarine cable interconnections across the Black Sea. It's a game-changer for the region, connecting Georgia with Romania through a high voltage direct current (HVDC) cable. The cable will run 1,195 km, with 1,100 km of it underwater, and have a voltage level of 500 kV and a capacity of 1,000-1,500 MW.

A fiber-optic cable will be laid alongside the electric cable to strengthen Internet connectivity between the Caucasus and the EU. This will be a crucial step in bridging the digital divide in the region. The project is initiated by Georgia, in partnership with Hungary, Romania, and Azerbaijan, pursuant to the Agreement on Strategic Partnership in the Field of Green Energy Development and Transmission.
The EU Commission fully supports the project, which is one of the bloc's five flagship projects. It's set to transform Europe's energy environment to become more secure and clean. The World Bank approved a $35 million loan for the first phase of the Enhancing Energy Security through Power Interconnection and Renewable Energy (ESPIRE) Program for Georgia in May 2024.
The ESPIRE Program consists of three phases with a potential financing envelope of up to $500 million. The first phase is especially critical, as it aims to help identify a suitable corridor for the BSSC Project and support further preparatory activities. This includes surveys of the Black Sea seabed, including geophysical and geotechnical investigations.
If Georgia and other participating countries decide to proceed with the implementation of the BSSC Project, Phase 2 of the ESPIRE Program would finance the strengthening of the on-land transmission grid in Georgia and potentially other countries. This would be crucial to enabling electricity exchanges through the submarine cable system.
Ukraine's Role in the System

The Black Sea Fiber-Optic Cable System is a crucial part of the global internet infrastructure, and Ukraine plays a significant role in it.
Ukraine is a key transit country for international internet traffic, with the Black Sea Fiber-Optic Cable System passing through its territory.
The system connects Europe and Asia, providing a vital link between these two continents.
The cable system spans over 1,000 kilometers, with Ukraine's portion being approximately 300 kilometers long.
This allows for fast and reliable data transfer between Europe and Asia, supporting international trade, education, and communication.
The Black Sea Fiber-Optic Cable System is a testament to the importance of international cooperation in the field of telecommunications.
Ukraine's unique geographical location makes it an ideal hub for this system, with the Black Sea providing a natural route for the cables to pass through.
The system has been operational since 2012, providing a reliable and high-speed connection between Europe and Asia.
This has had a significant impact on the global internet, enabling faster data transfer and supporting the growth of international online services.
Ukraine's involvement in the Black Sea Fiber-Optic Cable System has also brought economic benefits, with the country's economy benefiting from the increased trade and investment.

Frequently Asked Questions
Who owns the fiber optic cables under the ocean?
Fiber optic cables under the ocean are primarily owned and managed by consortiums of telecommunications and tech companies, including major players like Meta and Google. These privately owned cables form the backbone of global internet connectivity.
What happens if undersea internet cables are cut?
Cutting undersea internet cables can cause significant disruptions, potentially leading to widespread internet outages or even blackouts. This is because multiple cables are often connected to the same network, making a single cut have far-reaching consequences.
