FOX 3G HD-SDI • Introduction

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.

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.
Features
•
Fiber optic characteristics
— The FOX 3G HD-SDI sends and receives digital
optical signals via fiber optic small form factor pluggable (SFP) modules with LC-type
connectors.
•
E
xtends HD-SDI, SDI, and 3G-SDI signals very long distances over a single fiber
— The FOX 3G 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.
•
(FOX 3G HD-SDI P SM only) Immunity to SDI and HD-SDI pathological signal
patterns
— The FOX 3G HD-SDI P SM model adds immunity to pathological signals,
including test patterns defined by SMPTE RP 178 and SMPTE RP 198 for SD-SDI,
HD-SDI and 3G-SDI
•
Video input
— When it is configured as a transmitter, the FOX 3G 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.
