The FRRA is a fiber optic receiver integrated with the Blonder Tongue RMDA rack mount 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 (depending on model) VSB/AM modulated signals
over a single mode fiber. The FRRA operates with the FIBT Series of transmitters as well as with the transmitters of
many other leading manufacturers. The FRRA-S4A-860-43-PA can transfer 79 channels of VSB/AM signals, plus 57
digital QAM channels in the upper frequency range.
