DAGA2026 Scientific Acoustic Conference

Optics11 will present two technical papers at DAGA 2026, showcasing how optical sensing is advancing persistent Underwater Security and acoustic monitoring.

At DAGA, we will share insights into:

• OptiBarrier – our passive, all-optical seabed monitoring solution delivering Immediate, Over-the-Horizon Threat Detection, 24/7 for critical underwater infrastructure.

• The performance advantages of all-optical hydrophone technology, including high sensitivity, immunity to EMI, and long-range deployment without wet-end electronics.

OptiBarrier is a fibre-optic seabed sensor network designed for real-time detection and tracking across wide maritime areas. With no electronics underwater and high-fidelity acoustic acquisition (10 Hz–10 kHz, noise floor below Sea State 0), it enables persistent, covert monitoring for naval operators, offshore energy developers, and subsea cable owners .

Our presentations will highlight how optical architectures maintain performance over long distances and enable scalable, wide-area monitoring zones for ports, offshore wind farms, pipelines, and national maritime assets .
