IGC mode provides simple automatic compensation for fiber loss while output level tracks input level at SmartMON capable fiber transmitter

7708LRA L-Band/Wideband RF Fiber Receiver Series

The Evertz 7708LRA is a VistaLINK capable fiber optic receiver for extended L-Band and other signals. It accepts a fiber optic input from a companion transmitter and provides an electrical output signal. Monitoring and control of card status is provided locally at the card edge and remotely via VistaLINK. SmartMON capability allows inband monitoring data sent by a companion Smart MON enabled transmitter to be displayed locally or via SNMP/VistaLINK.

The LRA series occupies one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

Features

  • Protocol transparent - receives all video, audio and data 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
  • Two buffered RF outputs for extra signal distribution or monitoring functions
  • RF output independent of optical loss (within AGC/IGC gain range)
  • Available with BNC or F-Type connector options
  • Wide range optical input (1270nm to 1610nm)
  • Supports single-mode and multi-mode fiber optic cable
  • Available with SC/UPC, ST/UPC, FC/UPC, SC/APC and FC/APC connector options
  • Wide range adjustable gain in 0.5dB steps for fine tuning signal levels
  • Fully hot-swappable from front of frame
  • Comprehensive signal and card status monitoring via four-digit card edge display or remotely through SNMP and VistaLINK
  • VistaLINK capable for remote monitoring via SNMP (using VistaLINK PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • SmartMON capability for display of monitored parameters from companion SmartMON capable fiber transmitters
