A bidirectional transceiver can also simultaneously receive a proprietary signal from another
transceiver (in any configuration) on its Optical Rx port, convert the proprietary signal back
to the original format digital video, and output the video on its own two Buffered Outputs
BNC connectors.
Transmitter and receiver
NOTE: Although the description below does allow connection of a FOX 3G HD-SDI
configured as a bidirectional transceiver, the typical configuration is as shown: a
transmitter and one or more receivers.
A FOX 3G HD-SDI that is configured as a transmitter (see figure 3) inputs digital video
on its HD/SDI Input BNC. The transmitter converts the video input to a proprietary signal
and transmits the video over a fiber link to a FOX 3G HD-SDI that is configured as either a
receiver or a bidirectional transceiver. The transmitter also simultaneously outputs the digital
video on its two Buffered Outputs BNCs.

Figure 3. Transmitter-to-Receiver Connections
A FOX 3G HD-SDI that is configured as a receiver receives a proprietary signal on its Rx
fiber optic port. The receiver converts the proprietary signal back to original HD-SDI, SDI,
or 3G-SDI video and outputs the video on only one of its own Buffered Output BNC
connectors, Output 2.
The receiver converts the second digital video signal that it created from the optical input
back into a proprietary signal and outputs it on the Optical Tx port over a fiber link to
another FOX 3G HD-SDI that is configured as a receiver or as a bidirectional transceiver.
NOTE: Up to 10 receivers can be daisy-chained in this manner.
