7808RFT

7808RFT, 7808RFT-2 L-Band / Wideband RF over Fiber Transmitter Series

The 7808RFT is a high-performance RF over fiber transmitter platform available in single-channel (7808RFT) and dual-channel (7808RFT-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 7808RFT accepts a single RF input and provides a single fiber output, while the 7808RFT-2 accommodates two RF inputs and supplies two fiber outputs for optical transmission. Both configurations feature an RF monitoring port for each RF input, facilitating rapid monitoring or signal distribution. Selectable 13/18V DC LNB power +22kHz tone is also available per input, along with current limiting, short circuit protection and current monitoring for advance warning of LNB failure.

When housed inside Evertz' 570 Series and 7800 Series multi-frames, 7808RFT modules support 10MHz injection from the chassis' reference input, presenting a simple solution for applications requiring 10MHz insertion into the LNB, without the need for external devices. Please contact Evertz for more information on 10MHz RF over Fiber transport products.

For long-haul transport applications or instances with excessive optical loss, a high power DWDM version (-xxx, -xxx/yyy) offers an extended optical budget as well as the ability to interface with Evertz DWDM multiplexer systems for up to 40 channels onto a single fiber. A CWDM version (-xx, -xx/yy) is also available to accommodate up to 16 channels onto a single fiber. The 7808RFT13/15-2-W version presents an on-board fiber multiplexer (WDM), requiring only a single fiber between the companion receiver (7808RFR-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 output power, RF input 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 the 7808RFT 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 compatible Evertz receiver (e.g. 7808RFR), 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.
