Optii Corporation Information

Optii Corporation develops passive, photonics-based RF and fiber-optic sensing technologies designed for operation in electromagnetically contested environments. Our systems leverage nonlinear optical phenomena, including Brillouin light scattering and optical time-domain reflectometry (OTDR) in optical fibers, to detect, localize, and analyze activity across large geographic areas without emitting electronic signatures. Optii’s OTDR-based sensing enables long-range border and perimeter monitoring, providing continuous awareness along fiber-instrumented boundaries for intrusion detection, ground disturbance, and anomalous activity. When combined with Optii’s passive RF sensing architecture, the platform delivers multi-modal situational awareness without reliance on vulnerable electronic front-ends. Designed for dual-use deployment across defense, national security, aerospace, and civilian critical infrastructure, Optii technology supports applications including border and perimeter sensing, spectrum awareness, electronic warfare support, and resilient communications.
