About Optics11
Optics11 is a Dutch deep-tech company headquartered in Amsterdam that develops advanced fiber-optic sensing systems for monitoring and protecting critical maritime infrastructure. Using light instead of electricity, Optics11 technology enables highly sensitive and reliable detection in harsh offshore environments, delivering earlier warnings and improved underwater situational awareness.

OptiBarrier – Persistent Underwater Security
OptiBarrier is a passive fiber-optic seabed monitoring system that provides continuous, real-time underwater surveillance. Sensors placed on the seabed detect acoustic activity and transmit data via optical fiber to shore-based processing units.
• Fully passive sensors with no electronics underwater
• Real-time monitoring across large offshore areas
• Reliable, low-maintenance architecture

Offshore Wind Park Surveillance
Supports safe and secure offshore energy operations by monitoring activity around wind farms.
• Detection of vessels, anchors, and underwater vehicles
• Protection of turbines, substations, and export cables

Harbour Entry Surveillance
Provides an underwater security layer for ports and maritime gateways.
• Detection of divers and underwater drones
• Early warning of suspicious underwater activity

Critical Offshore Infrastructure Protection
Enables monitoring of vital subsea infrastructure such as pipelines and data cables.
• Early detection of disturbances near infrastructure corridors
• Increased protection of essential energy and communication networks
