Public maturity
TRL 6 complete; TRL 7 development and validation underway.
Public Technical Snapshot
What Optii has demonstrated, what remains in development, and what teams can evaluate now.
TRL 6 complete; TRL 7 development and validation underway. This page separates demonstrated results from roadmap goals and explains the scope of Optii's sensing contribution.
What passive sensing means
No local battery or powered detection electronics at the forward sensing head; central processing equipment requires power The passive description applies to the forward sensing head, not every element of the end-to-end system.
Demonstrated technical workflow
Results below are public, qualified snapshots rather than deployment guarantees.
Development roadmap
Planned expansion beyond the demonstrated X-band (8–12 GHz) engineering focus; not continuous demonstrated coverage.
Frequency response
Laboratory work has demonstrated a frequency-selective photonic response; no public linewidth measurement is stated.
Demonstrated sensitivity
Approximately -40 dBm under tested laboratory conditions
Fibre-link separation potential
Up to 100 km fibre-link separation potential, subject to system configuration and validation. This is not a free-space RF detection range.
Forward sensing head
No local battery or powered detection electronics at the forward sensing head; central processing equipment requires power
RF detection, optical transport and RF reconstruction have been demonstrated in the technology workflow Approximately -40 dBm under tested laboratory conditions.
Demonstrated band and roadmap
| Scope | Frequency statement | Meaning |
|---|---|---|
| Demonstrated | X-band (8–12 GHz) | Public demonstration evidence covers X-band operation. |
| Development roadmap | 1–40 GHz | A planned range for development and validation; it is not continuous demonstrated coverage. |
What the 100 km statement means
Up to 100 km fibre-link separation potential, subject to system configuration and validation. This describes potential separation along a fibre link between sensing and processing; it is not a claim of 100 km free-space RF detection range.
Role in a larger system
Counter-UAS
A potential passive RF sensing input within a layered architecture that may also include radar, electro-optical and other sensors.
Electronic warfare
A sensing and spectrum-awareness contribution; Optii does not present the public system as a complete electronic-warfare suite.
Maritime and perimeter
A fibre-connected sensing option for evaluation where teams want to separate an exposed sensing point from powered processing.
Evaluation available now
Defence, government, integrator and research teams can request a technical meeting to define signals of interest, sensing geometry, fibre access, interfaces and a controlled evaluation plan. Current software supports signal monitoring, operator display, alerting and integration work around detected and reconstructed RF signals AI-assisted signal classification remains a planned capability and is not presented as a current validated function.
Dated public evidence: the GCXpo 2025 Demonstrator & Exhibitor Overview describes Optii's X-band 8–12 GHz work. Detailed test setup, repeatability data and integration diagrams are available through a technical discussion where appropriate.
