7708LT Wideband RF Fiber Transmitter

The 7708LT is a fiber optic transmitter for RF signals in the extended L-Band or wider frequency range. It accepts a single RF input on coaxial cable and provides a single output for optical transmission. An RF monitor output provides a convenient means of obtaining peak satellite signal strength, or additional signal distribution.

Gain may be adjusted manually or managed automatically via AGC. With SmartMON™, incoming RF signal strength, LNB current and other data are relayed over the fiber output for monitoring through SNMP/VistaLINK® (requires SmartMON™ capable companion fiber receiver) 13/18V DC adjustable LNB power with 22kHz tone is also provided.

Features & Benefits

  • Extended frequency response for extended L–Band, off–air DTV, and other signals
  • Protocol independent design transports all modulation formats
  • LNB power with 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
  • RF monitor output for signal peaking and signal distribution
  • Manual gain and AGC modes
  • Wide range adjustable gain in 0.5dB steps for fine tuning signal levels and optimizing CNR
  • Available with 1310nm, CWDM (ITU–T G.694.2) and +11dBm high power DWDM (ITU–T G.694.1) laser options
  • SmartMON™ capability provides remote status monitoring via SNMP without a separate data connection
  • VistaLINK® capability is available for monitoring and control when modules are used in a 3RU 350FR, 7800FR frame and a 7700FC VistaLINK® frame controller is installed in Slot 1 of the frame
  • Fiber link provides electrical isolation between antenna and facility, mitigating ground loop and lightning issues
  • The 7708LT occupies one card slot and can be housed in a 1RU frame that will hold up to 3x modules, a 3RU frame that will hold up to 15x modules, a 350FR which will hold up to 7x modules or a standalone enclosure, which holds one module
