To bypass the physical routing constraints and high signal loss associated with traditional coaxial cabling in dense antenna assemblies, Optical Zonu Corporation (OZC) announced on Tuesday, July 28, 2026, the availability of its new OEM Miniature Ku-Band Radio Frequency-over-Fiber (RFoF) Transmitter. Measuring 2.25 x 1.0 inches, the compact module converts high-frequency RF signals to optical signals directly at the antenna interface.
Technical Parameters and Form Factor Specs
The transmitter is engineered for direct integration into phased array antennas, SATCOM terminals, radar systems, and military periscopes where spatial volume is limited.
Key operational parameters include:
- Frequency Range: Supports RF signal transport up to 18 GHz with high spur-free dynamic range (SFDR) and low-noise optical output.
- Optical Wavelengths: Operates at 1310 nm and 1550 nm optical wavelengths, with support for Dense Wavelength Division Multiplexing (DWDM) to route multiple RF channels over a single fiber strand.
- Thermal Range: Rated for fixed-gain operation from -20°C to +65°C, with extended thermal packaging options available for aerospace platforms.
- Form Factor: Fiber-pigtailed OEM construction designed to fit inside antenna masts, periscopes, and unmanned aerial vehicle (UAV) payload bays.
Application Rationale across Defense Systems
The module targets high-density radio-frequency platforms, including Common Data Link (CDL) hardware, shipboard communications, electronic warfare suites, and multi-band SATCOM terminals. By carrying signals via fiber optic lines rather than coaxial assemblies, the module reduces overall system weight while shielding signal lines against electromagnetic interference (EMI).
The technical deployment expands OZC’s defense hardware portfolio following earlier expansions in its Aerospace & Defense engineering division.
Executive Leadership Commentary
“Modern defense platforms are looking to pack more RF capability into less space than ever before,” said Brian Somers, Head of Aerospace and Defense at Optical Zonu. “By creating the industry’s smallest transmitter for the Ku-band, we’ve made it possible for system integrators to place optical conversion directly inside antennas, masts, and other highly constrained environments while maintaining the RF performance these applications demand.”
Availability and Hardware Pairing
The Miniature Ku-Band RFoF Transmitter is commercially available immediately for defense and aerospace integrators, with options for custom optical wavelengths and environmental ruggedization. While compatible with standard RFoF receivers, optimal dynamic range is achieved when paired with companion Optical Zonu receiver units.
