Wideband RF Fiber Transmitter for N+1 Redundant System

Model: 7808T13-8RF

  • 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/.

  • 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
  • LNB current limit and short circuit protection
  • LNB current monitoring for advance warning of LNB failure
  • 22kHz tone on/off for LNB local oscillator control
  • DC passthrough for downstream LNB power, allowing backup LNB power
  • Fully hot-swappable from front of frame with all cabling at the rear
  • Extended frequency response for extended L-Band and off-air DTV signals
  • Protocol independent design - transports all modulation formats
  • Supports manual, automatic (AGC) and intelligent (IGC) gain control modes
  • IGC mode provides simple automatic compensation for fiber loss while output level tracks input level at SmartMON™ capable fiber transmitter
  • Wide range adjustable gain in 0.5dB steps for fine tuning signal levels and optimizing CNR
  • SmartMON™ capability provides remote status monitoring via SNMP without a separate data connection
  • VistaLINK® PRO capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® PRO frame controller
  • SmartMON™ capability for display of monitored parameters from redundant transmitter module
