Optics11 specializes in advanced fiber-optic hydrophones for underwater security applications, including the protection of critical infrastructure, harbor surveillance, and the detection and tracking of submarines and other underwater threats. Our technology forms the core of integrated underwater surveillance systems, complemented by close collaboration with local partners to support ongoing technology development and deployment.

OptiBarrier forms a modular, fiber-optic seabed curtain that creates a persistent early-warning grid around harbors, wind farms, pipelines, and cables. It delivers Immediate, Over-the-Horizon Threat Detection, 24/7, with no wet-end electronics and intrinsic EMI immunity.

OptiArray for submarines and surface vessels is a thin-line, low-drag, all-optical towed array that brings high-sensitivity passive ASW to submarines. Its compact, low-power design scales to large channel counts and is immune to EMI, streaming clean, real-time acoustic data for detection and classification.
