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
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 has successfully deployed fiber as a replacement for waveguide to transport Ku-Band CDL communications payloads between radomes mounted high above the decks of ships and equipment rooms situated within the hulls of ships. Antenna Remoting over fiber enables greater flexibility to locate an antenna away from a radio head. Waveguide (and coaxial
