Product Overview
DESCRIPTION
The FR8302A fiber receiver provides the ability to accept two composite video channels over two
optical fibers. The FR8302A receiver is compatible with the FT8301A transmitter and is also backward
compatible with the FT8301 transmitter. Each of two transmitters can send a single independent video
channel to one FR8302A receiver (refer to Figure 1).
