Many redundant signal architectures may be constructed in Optical Zonu’s J3U chassis platform. 1+1 architectures are common, however as a spare transmitter/receiver pair are required for each primary transmitter/receiver pair, the cost and rack space required by such a redundant system may become prohibitive. N+1 architectures require a spare transmitter/receiver pair for each N transmitter/receiver…

There are many benefits to using optical links, in place of waveguide and coaxial cable, for the transport of RF signals. In situations where equipment (antennas, satcom modems, etc.) are separated by long distances (> 100 meters), optical links provide low loss signal transport (~ 0.7 dB/km RF attenuation). Unlike copper, this fiber attenuation is…

GPS is not only used for global positioning; many modern electronic communications systems rely on GPS distribution for timing and synchronization.  GPS distribution provides a global and universal time code signal that can be used to synchronize high speed communications between many different devices.  With wireless communications base stations becoming larger and more complex, they…

  Diagnosing failures in fiber optic links for telecommunications companies was the topic of this project conducted by a graduate student at Pontifical Catholic University, School of Computer Engineering and Telecommunications, in the Dominican Republic.  The project implemented was based upon “off-the-shelf” commercial products – adding the interface readout, and user functions, to make a…

DAS Interface Trays (DIT) are an essential part of any fiber optic DAS system.  These trays contain filters and amplifiers, and are responsible for conditioning the RF carrier signals for insertion into the remote Distributed Antenna System (DAS).  The optical transport step of a distributed DAS combines and lowers the power levels for all carriers…

Optical Zonu Testimonial Airwavz and Optical Zonu have been working together multiple years. Both pre/post pandemic, Optical Zonu has been able to manage their timelines with exceptional communication. In a direct correlation from their transparency, it has made Airwavz be able to thrive and meet our dates to satisfy our customers as well. Optical Zonu…

RF over Fiber (RFoF) products are being used widely across the Telecom industry over the last decade. The technology transformation of RF transport replacing traditional Coaxial will only continue to increase for the foreseeable future. Optical Zonu is a premier OEM for RFoF since 2003 recognized and approved by all three US wireless carriers (Verizon,…

Industry standard SFP digital data transceivers are widely deployed in Switch, Router and other network equipment.  OZC offers direct functional replacements of these transceivers, with the additional capability to instantly detect, locate (within a few dozen meters) and report optical fiber faults to the NOC (network operations center) utilizing SNMP.  We call this the Micro-OTDR™…
