Optical Zonu - RF over Fiber (RFoF)
Components, Modules & Systems
We enable resilient RF transport for next-generation communications, sensing, SATCOM, radar, and AI-enabled defense infrastructure.
Carrier-Grade GPS RF Over Fiber Links
Optical Zonu's GPS Fiber Transport links connect your GPS antenna and receiver in situations where coaxial cable is not desirable or practical. These RF-over-Fiber links are easy to install and ensure signal purity for long cable runs or optical splits to multiple locations.
Universal Base Station to DAS
Fiber Transport System
Optical Zonu's BTS-DAS Fiber Transport links provide a highly reliable RF connection between the base station and DAS head end. These systems and modules minimize the amount of equipment and fiber needed while supporting full MIMO, multiple sectors, and public safety.
iSFC Transceiver:
Industry-Recognized Innovation
Our revolutionary iSFC transceiver, with built-in fault-finding Micro-OTDR was recently recognized by Lightwave Magazine's Innovation Awards.
