The FOX HD-SDI units output continuous,
invisible light, which may be harmful and
dangerous to the eyes; use with caution.
•
Do not look into the rear panel fiber optic
cable connectors or into the fiber optic cables,
themselves.
•
Plug the attached dust caps into the optical
transceivers when the fiber optic cable is
unplugged.

The two products are physically and functionally identical,
with the exception of the effective range of transmission.
In this manual, the term "FOX HD-SDI" refers to either
product.
About the FOX HD-SDI
The Extron FOX HD-SDI product family consists of two models
(MM and SM) of high performance digital (HD-SDI, SDI, or
3G-SDI) video fiber optic transceivers. The transmitted signal
can include any audio or unidirectional serial data that is
embedded in the input video.
N
All transceivers in the system must be the same model (all
singlemode or all multimode).
Transceiver configurations
The transceiver can be configured via its rear panel Mode DIP
switches to operate in one of three ways:
• Bidirectional transceiver
• Transmitter
• Receiver
N
See item
b
, "Mode switches", on page 2-11 to set the
configuration.
Bidirectional transceiver
N
In this manual, the term "transceiver" refers to any FOX
HD-SDI; the term "bidirectional transceiver" refers to a
FOX HD-SDI configured as described in this section.
N
Although the description below does allow connection of
a FOX HD-SDI configured as transmitter or receiver,
the typical configuration is as shown: two bidirectional
transceivers.
A FOX HD-SDI that is configured as a bidirectional transceiver
(figure 1-2) inputs digital video on its SDI/HD-SDI Input BNC.
The transceiver converts the video input to a proprietary signal
and transmits the video over a fiber link to another FOX HD-SDI
that is configured as a bidirectional transceiver or as a receiver.
