Interact with this product in a Layout Tool:
The 7808RFR is a high-performance RF over fiber receiver platform available in single-channel (7808RFR) and dual-channel (7808RFR-2) configurations. This modular and hot-swappable card is designed for integration inside the 7800FR, 7801FR, 5710FR, and 350FR enclosures. It seamlessly integrates with Evertz' 7800 series RF products, such as RF splitters/combiners, RF routers, spectrum analyzers, IRDs, and demodulators.
The 7808RFR accepts a single fiber optic input and provides a single RF output, while the 7808RFR-2 accommodates two fiber optic inputs and supplies two RF outputs. Both configurations feature an RF monitoring port for each RF output, facilitating rapid monitoring or signal distribution to downstream devices.For longhaul transport applications or instances with excessive optical loss, a high-sensitivity version (-H) offers an extended optical budget. The dual-channel receiver is available with the option (-W) for an on-board fiber de-multiplexer (WDM), requiring only a single fiber between the companion transmitter (7808RFT13/15-2-W).
Gain control, essential for tuning optimal CNR performance, can be conveniently managed either locally or remotely using manual mode or the Automatic Gain Control (AGC) mode. Additionally, the system provides detailed monitoring of various parameters such as optical input power, RF output power, temperature, and more, with individualized information available for each RF input. This comprehensive monitoring capability enhances the user's ability to maintain and optimize performance, ensuring efficient and reliable operation.
The modules provide a seamless and user-friendly experience for remote monitoring and control via the WebGUI interface and/or SNMP/VistaLINK PRO®. With the integration of Evertz' innovative SmartMON™ technology, operators can efficiently monitor compatible Evertz transmitters from a distance without the need for a separate data connection. Vital information, including RF input power, gain settings, LNB current, DC input power, internal temperature, and laser status, is transmitted over fiber to the 7808RFR receiver, enabling easy access through SNMP or WebGUI. This advanced system ensures comprehensive oversight and control, enhancing operational efficiency and facilitating streamlined management of Evertz transmitters.
