Optics11
Optics11 develops advanced fiber-optic sensing systems for the world's harshest environments, including seabed threat detection, towed arrays for submarines, and partial discharge monitoring for energy infrastructure. Its passive, EMI-immune sensors deliver real-time data with high sensitivity and low power consumption, enabling earlier warnings and more time to act. The OptiFinder system, for example, localizes partial discharges in transformers with up to 15 cm accuracy using 32 acoustic sensors.

Problem
Critical infrastructure such as power transformers, seabed cables, and naval assets operate in harsh environments where traditional electronic sensors are vulnerable to electromagnetic interference, require frequent recalibration, and often fail to detect emerging threats or faults early enough for preventive action. This leads to costly downtime, security vulnerabilities, and reduced asset lifespan.
Solution
Optics11 provides advanced fiber-optic sensing systems that deliver ultra-sensitive, reliable, and low-power monitoring for defense and energy applications. The company's passive optical sensors are immune to EMI, require no power at the sensing location, and can be deployed in extreme conditions where electronic systems fail. For energy infrastructure, the OptiFinder system monitors partial discharges in transformers 24/7, automatically detecting, classifying, and localizing faults with centimeter-level accuracy. For underwater security, OptiBarrier creates a persistent fiber-optic seabed curtain for immediate over-the-horizon threat detection, while OptiArray provides thin-line towed arrays for submarines and unmanned vessels. All systems stream real-time data to command or maintenance platforms, enabling faster decision-making and proactive risk mitigation.
Target Audience
Primary customers include defense organizations and naval forces requiring underwater threat detection and anti-submarine warfare capabilities, as well as transmission system operators, energy utilities, and industrial asset managers needing continuous monitoring of transformers and electrical infrastructure.
