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 to back to the original format digital video, and output
the video on its own two Buffered Outputs BNC connectors.
Transmitter and receiver
N
Although the description below does allow connection of a
FOX HD-SDI configured as a bidirectional transceiver, the
typical configuration is as shown: a transmitter and one or
more receivers.
A FOX HD-SDI that is configured as a transmitter (figure 1-3)
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 HD-SDI that is configured as
a receiver or as a bidirectional transceiver. The transmitter also
simultaneously outputs the digital video on its two Buffered
Outputs BNCs.

A FOX 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 Rx port over a fiber link to another
FOX HD-SDI that is configured as a receiver or as a bidirectional
transceiver.

Up to 10 receivers can be daisy-chained in this manner.
Features
Extends HD-SDI, SDI, and 3G-SDI signals very long distances
over a single fiber — The FOX HD-SDI supports multi-
rate SDI at rates up to 2.97 Gbps, and complies with
SMPTE 259M-C, 292M, 424M, and ITU digital video
standards.
Video input — When it is configured as a transmitter, the
FOX HD-SDI inputs digital video on a BNC connector.
HD-SDI loop-through — The transceiver has two Buffered
SDI/HD-SDI BNC connectors that allows connection of
a local monitor when the transceiver is configured as a
transmitter.
Video output — The transceiver outputs digital video on one
or two Buffered SDI/HD-SDI BNC connectors when it is
configured as a bidirectional transceiver or a receiver.
Dual buffered outputs — When the FOX HD-SDI is configured
as a transmitter, the SDI/HD-SDI BNC output connectors
can be used for previewing the video on a local monitor.
Input equalization and reclocking on buffered outputs — The
FOX HD-SDI automatically equalizes incoming multi-
rate SDI signals, and reshapes and restores signals on its
buffered outputs.
Daisy chain capability — Up to 10 transceivers can be daisy
chained to send the video to multiple locations when one
of more units are configured as receivers.
Real-time status LED indicators for troubleshooting and
monitoring
1" high, quarter rack width, metal enclosures — With low
profile enclosures, the transceiver can be discreetly
installed in a variety of locations, such as behind a plasma
or LCD flat-panel display.
Rack mountable — The unit is rack mountable in any
conventional 19" wide rack, using any of a variety of
Extron's rack shelves.
Power — The unit's 100 VAC to 240 VAC, external power supply
provides worldwide power compatibility.
