N The multimode and singlemode fiber optic I/O boards are physically and
functionally identical, with the exception of the effective range of transmission.
In this manual, any reference to fiber optic transmission applies to either
transmission mode unless otherwise specified.

The FOX 4G matrix switchers' fiber optic I/O boards 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.
Fiber optic I/O boards route signals that are compatible with all Extron fiber optic
product lines. SDI/HD-SDI I/O boards route serial digital interface (SDI) and high
definition serial digital interface (HD-SDI) signals. The matrix switcher routes any
input signal to any combination of outputs. An optical input can be tied to both
optical and SDI/HD-SDI outputs and an SDI/HD-SDI input can be tied to both
SDI/HD-SDI and optical outputs. The matrix switcher can route multiple input/
output configurations simultaneously.
The Extron proprietary fiber optic signal, generated by equipment such as FOX 500
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, SDI/HD-SDI video, or low resolution video,
depending on the transmitter and receiver. The switchers have two internal, hot-
swappable 100 VAC to 240 VAC, 50-60 Hz, 175-watt power supplies that provide
worldwide power compatibility and reliability.
N Compatible optical signals are digital signals from 270 Mbs through 4.25 Gbps
that are sent and received via fiber optic small form factor pluggable (SFP)
modules. The FOX 4G matrix switchers support all compatible optical signals,
whether transmitted or received by an Extron FOX system component or not.
N The Extron FOX transmitter-to receiver communications, including the serial
link, occupy one matrix switcher input and output.
This matrix switcher also supports the Extron FOX return (receiver-to-
transmitter) serial communications, but returning this signal stream to the
transmitter uses a separate matrix switcher input and output.
The matrix switchers are a single box solutions to complex fiber optic and
SDI/HD-SDI signal routing applications. Each input and output is individually
isolated and buffered, and any input(s) can be switched to any one or all outputs
with virtually no crosstalk or signal noise between channels.
By adding or removing I/O boards, the Fox 4G Matrix 3200 is expandable and
contractable, from an 8-input by 8-output matrix to a 32-input by 32-output matrix.
The FOX 4G Matrix 7200 is expandable to a 72-input by 72-output matrix. The
matrix switchers input and output the optical signals that they route on fiber optic
transceiver modules and the SDI/HD-SDI video signals on BNC connectors.
The matrix switchers can be remotely controlled via their rear panel Remote
RS-232/RS-422 ports, their rear panel LAN port, and their front panel
Configuration (RS-232) port using either the Extron Windows
Switchers Control Program or the Simple Instruction Set (SIS
basic ASCII code commands that provide simple control through a control system
or PC without programming long, obscure strings of code.
