Fiber Optic Receiver
Figure 1. Typical FOX SW8 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, Digital Visual Interface (DVI) or High-Definition Multimedia Interface
(HDMI) video, or SDI/HD-SDI video.
• The serial component of the signal is for applications such as projector control and
transmitter control of the receiver.
The switcher selects among the proprietary signal inputs and outputs the selected signal on
a fiber optic cable to a compatible receiver.
NOTES:
• The FOX SW8 does not support transmission of a return (Rx-to-Tx) serial data
stream.
• The switcher is compatible with most Extron FOX, FOXBOX, and PowerCage FOX
models. The switcher is not compatible with the DFX 100 and HFX 100 Extender
models.
The connected receivers convert the proprietary signals back to video (RGB, DVI, or
SDI/HD-SDI, 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 switcher via a transmitter.
