The FRRA is a fiber optic receiver integrated with the
Blonder Tongue RMDA distribution amplifier. The
FRRA may be used as a launch amplifier in a coaxial
distribution network after networking with fiber. The
fiber receiver provides a robust system for transferring
110 channels of VSB/AM modulated signals over a
single mode fiber. The system provides for up to
860 MHz of usable bandwidth for video signals stacked at 6 MHz intervals.
The FRRA operates with the FIBT Series of transmitters as well as with the transmitters of many leading manufacturers.
The distribution amplifier in the FRRA is based on the RMDA series of amplifiers. The FRRA series can receive
and amplify 80 channels of VSB/AM signals, plus 30 digital QAM channels.
