3.0GHz Programmable RFoF Transmitters & Receivers
RF over Fiber 3.0GHz operate between 1MHz to 3GHz provide long distance RF signal transport over Single Mode Fiber and are commonly used for applications in the L band such as point-to-point, cellular, broadcast, GPS, satcom, and remote antenna. Their compact design and the low power consumption make them ideal for standalone and subsystem applications. The modules are available with FC/APC or with SC/APC optical, and SMA RF connectors.
Each 3GHz link has a transmitter (Tx) and a receiver (Rx) modules which may be controlled via RFOptic Configuration tool app. The app provides access to settings, features and diagnostic parameters. The software tool can activate built in Temperature compensation algorithms, RF level monitoring and Automatic Level Control as well as BIT and RF link test diagnostics, and log file that simplify troubleshooting in the field and allow remote tech support.
RFOptic solutions may be installed into indoor enclosures and/or outdoor enclosures. Selection of enclosure is made according to the number of modules and additional required components based on available space, environmental conditions, maintenance parameters, and customer needs.
