About

Optii Corp. is a Canadian defence and aerospace technology company developing passive photonic sensing systems for radio frequency detection, signal awareness, and resilient operations in contested environments. Its technology uses fibre-optic sensing principles to detect and characterize RF activity without requiring powered electronic components at the sensing end, making it highly resistant to interference, jamming, spoofing, and harsh environmental conditions.

Designed for defence, aerospace, critical infrastructure, and advanced communications applications, the Optii system enhances situational awareness by adding a passive sensing layer that can operate where conventional electronic systems may be vulnerable. The company is advancing both its sensor hardware and software platform to support real-time interpretation, classification, and integration into partner systems.
