When we talk about GPS over Fiber, GPSoF, most think about timing for a Data Center or a Cellular Base Station.  There are many other applications for GPS.  GPS, or Global Positioning System, is often used for positioning, tracking vehicles, or people.  We rely on GPS for directions on our phones. One application is on…

Is it possible to use the Dual-Fiber Micro-OTDR SFP to monitor single-fiber optical links?  This is a question that we are often asked by our CSP and OEM Customers who want to monitor lengths of optical fiber (SMF-28 and similar), but do not need to send data.  That is, they do not want to make…

  Optical Zonu designs and manufactures both fixed and variable delay lines (up to 2 msec total). RF frequencies up to 50 GHz may be delayed. Switched delays with 4-, 8-, 12-bit (or more) delay resolution are available. Managed RFoF remote control (graphical user interface) is used to manage switch states remotely. of variable switched…

  In this fast paced and quickly changing world, businesses come and go and decline and grow. If you have been purchasing your RFoF, GPS, or Base Station to DAS equipment from a business that seems to be waning, then it is time to discover Optical Zonu Corporation (OZC). OZC offers one of the broadest…

  Cell phone service at the Super Bowl Experience is an important aspect for fans, players, and the media. With hundreds of thousands of people gathering at one location, the demand for cell phone service is high, and it can be a challenge for providers to meet this demand. For this upcoming event in Phoenix,…

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…
