About the FOX DA8 Plus
The FOX DA8 Plus units are singlemode and multimode ultra-high performance fiber optic
distribution amplifiers. The DA (see figure 1) accepts a proprietary input optical signal from
a compatible Extron fiber optic transmitter (Tx) or other device. The optical signal can include
video, audio, and one-way (transmitter-to-receiver [Rx]) RS-232 communications.

Figure 1. Typical FOX DA8 Plus Application
NOTES: • Compatible optical signals are digital signals from 2.0 Mbps through
4.25 Gbps that are sent and received via fiber optic SFP modules.
• The video component of the signal from an Extron Tx can be either
VGA - UXGA RGB video, High-Definition Multimedia Interface (HDMI), or
digital visual interface (DVI) video.
• Distribution of HDMI video is not HDCP-compliant.
• The serial component of the signal is for applications such as projector control
and transmitter control of the receiver.
The FOX DA8 Plus actively splits the proprietary signal into eight identical optical signals and
outputs the signals on fiber optic cables to compatible receivers.
NOTES: • The eight optical outputs are identical.
• The FOX DA8 Plus does not support transmission of a return (Rx-to-Tx) serial
data stream.
• The DA can receive and send the proprietary signal from and to any compatible
Extron fiber optic transmitter, receiver, or switcher (see “Compatible
Equipment” on page 20 for a partial list of compatible products).
The connected receivers convert the proprietary signals back to video (RGB, HDMI, or
DVI, depending on the source transmitter and the receiver), audio, and serial RS-232
communication, and output the signals locally. For video resolutions up to 1900x1200, the
video outputs for the receivers are a perfect, pixel-for-pixel or digital recreation of the video
signal input to the FOX DA8 Plus via a transmitter.
