  • •Optics11 raised €50 million to enhance undersea monitoring technology.
  • •The technology can detect activities up to 100 kilometers away from the coast.
  • •Demand for this technology is rising due to threats against critical infrastructure.

Dutch firm Optics11 has raised €50 million to enhance its fiber-optic technology for monitoring undersea cables and critical infrastructure. The company has seen increased demand for its technology due to rising threats of sabotage and hybrid attacks. Optics11's systems can detect sound and vibrations up to 100 kilometers away, making them suitable for monitoring activities near undersea cables. The new funding brings the total capital raised by the company to over €100 million in the past 15 months. The technology is being tested by several navies, including Germany, Sweden, and the UK, and is part of a broader effort to secure maritime infrastructure. CEO Paul Heiden noted that the technology is crucial for future naval operations and is currently deployed in classified environments. Optics11 plans to expand its production capacity and accelerate international growth with this investment.
