FOX Matrix 320x and FOX Matrix 14400 • Introduction2 3FOX Matrix 320x and FOX Matrix 14400 • Introduction
NOTES:
•  Compatible optical signals are digital signals from 270 Mbs 
through 4.25 Gbps that are sent and received via ber optic 
small form factor pluggable (SFP) modules.
•  The FOX transmitter-to-receiver communications, including the 
serial link, occupy one matrix switcher input and output. This 
matrix switcher can also support the FOX return (receiver-to-
transmitter) serial communications, but returning this signal 
stream to the transmitter occupies a separate matrix switcher 
input and output.
The switcher has two (FOX Matrix 14400) or four (FOX Matrix 320x) 
internal, hot-swappable 100 VAC to 240 VAC, 50-60 Hz, 400-watt power 
supplies that provide worldwide power compatibility and reliability.
Configurability and Transmission Modes
The FOX matrix switchers are assembled from individual input/output 
(I/O) boards. The switcher can include up to 9 (FOX Matrix 14400) or 20 
(FOX Matrix 320x) I/O boards, each of which supports 16 inputs by 16 
outputs. The four types of I/O boards are:
 • Singlemode fiber optic 16x16 I/O board
 • Multimode fiber optic 16x16 I/O board
 • Singlemode pathological fiber optic 16x16 I/O board. This board 
addresse the compatibility issues of passing pathological signals 
generated from 3G HD-SDI, HD-SDI, and SDI signals over ber optic 
systems
 • 3G HD-SDI, HD-SDI, and SDI 16x16 I/O board
NOTE:  As listed above, three versions of the fiber optic I/O boards 
are documented in this manual. They are categorized by the type 
of fiber optic cable, multimode or singlemode, which defines the 
effective range of transmission:
•  Singlemode — Very long distance, up to 30 km (18.75 miles)
•  Multimode — Long distance, up to 300 m (984 feet)
By adding or removing I/O boards, you can expand and contract the FOX 
Matrix Switchers from an 16-input by 16-output matrix to up to either:
 • FOX Matrix 14400 — A 144-input by 144-output matrix
 • FOX Matrix 320x — A 320-input by 320-output matrix
NOTE:  On a fiber optic I/O board as delivered from Extron, all 
transceiver modules are configured the same: either all multimode 
or all singlemode. You can mix multimode and singlemode fiber 
optic I/O boards in a FOX matrix switcher, but you must ensure 
that you connect the proper transmission mode fiber cables to the 
board.
About the FOX Matrix Switchers
The FOX matrix switchers (see gure 1 for a FOX Matrix 14400 example) 
are congurable matrix switchers that distributes optical signals. Fiber 
optic I/O boards route signals that are compatible with all Extron 
FOX 500, FOXBOX, FOX, FOX 2G, and FOX HD-SDI ber optic product 
lines. 3G/HD-SDI/SDI/ I/O boards route 3G, high denition serial digital 
interface (HD-SDI), and serial digital interface (SDI) signals. The matrix 
switcher routes any input signal to any combination of outputs. An 
optical input can be tied to optical outputs, 3G/HD-SDI SDI outputs, 
or both and an 3G/HD-SDI SDI input can be tied to 3G/HD-SDI/SDI 
outputs, optical outputs, or both. The matrix switcher can route multiple 
input/output congurations simultaneously.

Figure 1.  Typical FOX Matrix 14400 application
NOTE:  In figure 1, the FOX 3G HD-SDI is set to bidirectional 
transceiver mode.
 The Extron proprietary ber optic signal, generated by Extron ber 
optic transmitters, can include video, stereo audio, and transmitter-
to-receiver RS-232 serial communications. The video component of 
the signal can be RGB video, Digital Visual Interface (DVI) video, HDMI 
video, 3G/HD-SDI/SDI video, or low resolution video, depending on the 
transmitter and receiver.
The matrix switcher can be remotely controlled via its Ethernet LAN port 
or either of two serial ports, one on the rear panel and one on the front 
panel, using either the Windows-based Extron Matrix Switchers Control 
Program or the SIS.
