The 7708LTxx-B50 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.

LNB power with selectable 13/18V DC
LNB current limit & 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
The 7708LT 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
SmartMON™ capability provides remote status monitoring via SNMP without a separate data connection
VistaLINK® capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
Fiber link provides electrical isolation between antenna and facility, mitigating ground loop and lightning issues
