RF over Fiber N+1 Redundancy Series
Model: 7808R-8RF
- Redundancy up to 8+1
- Wideband 88MHz to 3GHz for IF, L-Band, extended L-Band applications
- RF and DC passthrough using passive rear plate, providing true redundancy
- Local Control/Data port
- The 7808T acts as a redundant LNB powering system in case of main LNB path failure; standard selectable 13/18V DC
The 7808T/R-8RF series is a card-based RF over Fiber N+1 redundancy system up to an 8+1 configuration; mountable inside Evertz 7800 series multi-frames. Integrated with Evertz' modular RF over Fiber system, the 7808 Series provides a redundant RF over Fiber path with automatic and/or manual switching in the case of a main path failure (damage of fiber optic cable, transmitter, receiver, LNB power, etc.).
Monitoring and control of card status is provided locally at the card edge and remotely via NMS software. Advanced features include 13/18V LNB adjustable power and monitoring with 22kHz tone, wide range of manual/IGC/AGC gain, DC and RF passthrough and more.
The 7808T13 is a dual-slot module which provides redundancy for Evertz' RF over Fiber transmitters. It has 8x RF inputs and a single optical output with a built-in switch and wideband transmitter. With Evertz' proprietary SmartMON™ monitoring software, incoming RF signal strength, LNB current and other data are relayed over the fiber output for monitoring through SNMP/.
The 7808R is a dual-slot module which provides redundancy for Evertz RF over Fiber receivers. It has a single optical input and 8x RF outputs with a built-in switch and wideband receiver.
