The show will consist of 4 event days, with the main conference taking place over 3 days. Networking is a very large component of SubOptic and 4 themed networking sessions will take place over the event dates.

The theme for the 2025 conference is What’s on the horizon? Future proofing our digital landscape.

Adoption of new technologies, laws, working practises and attitudes is required to address our rapidly changing digital landscape. The rise of Artificial Intelligence, increasing security requirements, environmental and geopolitical change, bring with them a requirement for development, standardization and flexibility. As society’s dependency on the Internet continues to grow, the pressure to provide reliable, sustainable and high-capacity subsea networks means today, more than ever, we must evolve and protect our critical infrastructure.

SubOptic 2025 asks the question ‘What’s on the horizon?’ and challenges the subsea community to look into the future and determine how best to address the variety of in-coming demands on-land, at-sea and in the cloud.
