About the FOX AEX 108 and FOX II AEX 108 Fiber Optic Audio
Extractors
The extractors are eight input fiber audio extraction products that extract local audio in a
fiber matrix or point-to-point applications. It can be installed on the output side of the fiber
matrix.
NOTES:
• The multimode and singlemode extractors are physically and functionally identical
with the exception of the effective range of transmission.
• The FOX AEX 108 extractors are compatible with all FOX series products except for
FOX 3G HD-SDI, PowerCage FOX 3G HD-SDI and FOX 3G DVC models.
• The FOX II AEX 108 extractors are compatible with all FOX Series and FOX II Series
products except for FOX 3G HD-SDI, PowerCage FOX 3G HD-SDI and
FOX 3G DVC models.
• Different modes are not compatible with each other.

FOX AEX 108 and FOX II AEX 108 Fiber Optic Audio Extractors • Introduction 2
Features
Local audio outputs —Local audio outputs for up to eight FOX Series or FOX II Series
fiber optic signals, extracting analog stereo audio for independent processing and routing
Inputs — Eight fiber optic LC connectors with buffered Loop-throughs
Outputs — Eight 5-pole captive screw connectors for balanced or unbalanced analog
stereo audio
Simultaneous audio extraction ports — Depending on the model, each port accepts
signals from either FOX Series or FOX II Series fiber optic products to provide local analog
stereo audio output, and retransmits the fiber optic signal at the original power level.
Buffered input loop-throughs — Full transmitter power on each output maximizes
distance capabilities by ensuring full availability of optical loss budget.
Balanced or unbalanced analog audio outputs — Provide balanced or unbalanced
stereo audio on captive screw output connectors for integration with audio processing and
distribution equipment.
Output reclocking — Reshapes and restores timing of the digital signal.
Multimode and singlemode availability — Available as an 850 nm multimode model for
moderate-range transmissions and a 1310 nm singlemode model for extreme distances
up to 30 km (18.75 miles). The extractor, connected between a FOX Series or FOX II Series
transmitter and receiver, effectively doubles the overall transmission distance capability. For
singlemode applications, signals can be sent up to 60 km (37.5 miles) from a transmitter to
a receiver via the extractor.
Reliable physical connectivity — Industry standard LC connectors provide reliable
physical connectivity and precise fiber core alignment.
Real-time status LED indicators — Front and rear panel LEDs verify signal presence, link
status, and power for troubleshooting and monitoring.
Compatibility with the following Extron FOX Series or FOX II Series:
• Matrix switchers — Provides a convenient location for audio extraction in a matrix
switching environment for signal distribution systems up to 1000x1000 and larger. Each
port includes an input with a loop-through, enabling in-line installation without using
valuable dedicated switching resources or a matrix switcher slot.
• Distribution amplifiers —Supports virtually any fiber optic switching and distribution
environment for maximum design flexibility.
• HDMI, DisplayPort, DVI Plus, DVI, VGA, VGA/YUV, and AV transmitters and
receivers — Provides audio extraction for a wide variety of sources and displays.
NOTES:
• The FOX AEX 108 extractors are compatible with all FOX Series products except for
the FOX 3G HD-SDI extender or FOX 3G DVC signal converter.
• The FOX II AEX 108 extractors are compatible with all FOX Series and FOX II Series
products except for the FOX 3G HD-SDI extender or the FOX 3G DVC signal
converter.
• Transmission of HDMI and DisplayPort video and HDCP content requires two fibers.
Rack-mountable — Compact 1U half-rack width metal enclosure enables up to 16
extraction ports in a 1U rack space.
Internal universal power supply — The 100-240 VAC, 50 or 60 Hz, international power
supply provides worldwide power compatibility.
Input Data Rate Selection — A recessed toggle switch on the front panel allows for
selectable input data rates. The extractors can be set to 2G or 4G rates. These selectable
rates apply to all inputs; they are not for individual inputs.

FOX AEX 108 and FOX II AEX 108 Fiber Optic Audio Extractors • Introduction 3
Application Diagrams
The extractors can be used anywhere local audio-only outputs are required. This may
include the input or output side of a fiber optic matrix application or between a fiber optic
transmitter and receiver. Integrating the extractor on the input side of a FOX matrix switcher
allows for independent processing of source audio signals by a DSP processor. Integrating
the extractor on the output side of a FOX matrix switcher routes the audio to amplifiers or a
DSP processor. The extractors include eight extraction points for eight inputs. Each audio
extraction point works independently.
NOTES:
• The extraction points in all three applications work independently.
• Transmission of HDMI or DisplayPort video with HDCP content requires a return
fiber optic cable from the receiving device to the transmitting device.
The following applications are examples of typical integrations of the extractors in fiber optic
systems.
Point-to-point Application
In systems without a fiber matrix switcher, the extractors can be incorporated between the
fiber transmitter and the fiber receiver.

Figure 4. Rear Panel Connectors (FOX II AEX 108 Shown)
AAC power connector — Plug a standard IEC power cord into the connector to
connect the extractor to a 120 V or 240 VAC, 50 or 60 Hz power source.
BFiber optic connectors — One dual port LC SFP module for fiber Tx or Rx
transmission with two LEDs for fiber link status.
WARNING: These units output continuous invisible light; use with caution. Plug the
attached dust caps into the optical transceivers when the fiber cable is unplugged.
AVERTISSEMENT: L’appareil émet une lumière invisible en continu, à utiliser
avec précaution. Branchez les protections contre la poussière dans l’ensemble
émetteur/récepteur lorsque le câble fibre optique est débranché.
NOTE: Ensure the proper fiber cable is used. Typically, singlemode fiber optic
cables have a yellow jacket and multimode fiber optic cables have an orange or
aqua jacket.
Tx connector — Connect a fiber optic cable to the Tx port of the extractor to an Rx
port of a FOX receiver or FOX matrix switcher input.
Rx connector — Connect a fiber optic cable to the Rx port of the extractor to a Tx
port of a FOX transmitter or FOX matrix switcher output.

CTx and Rx indicator LEDs — The optical Tx and Rx LED indicators light to indicate
light presence.
DAudio connectors — Insert a 3.5 mm, 5-pole captive screw audio connector for
each extraction point. This output is unamplified line level audio. Wire the connector as
shown in figure 5.
Do not tin the wires!

BAudio Signal LED indicators — Each indicator lights when an audio signal above
–35 dBV is detected on the associated fiber input. The LED lights immediately when the
signal goes above that threshold, but turns off after the audio signal level remains below
the threshold for 10 seconds.
CRecessed toggle switch — A recessed toggle switch that selects the input reclocking
to maintain signal integrity on all inputs. Selects between 2G and 4G input data rates.
NOTE: The default switch position is down (4G).

FOX AEX 108 and FOX II AEX 108 Fiber Optic Audio Extractors • Installation and Operation 8
System Operation
Wiring Configurations
The extractors can be used anywhere local audio-only outputs are required (see
Application Diagrams on page 3 for potential applications). Each extraction point on the
extractor works independently—the audio extracted from the extraction point is taken from
the associated fiber connector.
Transmission of HDMI or DisplayPort video with HDCP content requires a return fiber optic
cable between the endpoints. Otherwise, digital video output by the receiver will not be
HDCP-compliant and RS-232 reports will not be available from the controlled device. For
this bidirectional serial communication and HDCP-compliance along an extraction point on
the extractor, connect a fiber optic cable between the Rx port on the transmitter and the Tx
port on the receiver.
NOTES:
• Upon startup, all Audio Signal LEDs blink together to identify SFP module. The
LEDs blink once for multimode and twice for singlemode. Afterwards, the LEDs
return to their normal signal presence indication.
• The front panel LEDs blink repeatedly if multimode and singlemode SFP modules
are mixed in the system or if the wrong part number is assigned. The unit does not
work properly until the correct SFP module is paired with the correct model.
If any problems are encountered, ensure all traditional and fiber cables are routed and
connected properly.
TIP: If problems persist, call the Extron S3 Sales and Technical Support Hotline (see the
Contact information on the last page for contact numbers).
Changing the Input Data Rate
Use the recessed toggle switch on the front panel to select between 2G and 4G input data
rates. Cycle power to the extractor after changing between 2G and 4G. The default rate is
4G (Off or left position).
ATTENTION:
• Ensure all fiber extenders within the system are compatible with the selected input
data rate.
• Assurez-vous que tous les extendeurs fibres dans le système soient compatibles
avec le débit de données d’entrée sélectionné.
NOTE: Selectable rates apply to all extraction points. They are not for individual inputs.

The 1U high, half-rack width unit can be placed on a tabletop or mounted on a rack shelf.
Tabletop Use
If necessary, place four rubber feet to the four bottom panel corners of the extractor and
place the extractor on a flat and level surface.
UL Guidelines for Rack-Mounting
The following Underwriters Laboratory (UL) guidelines pertain to the installation of the
extractor in a rack.
1. Elevated operating ambient temperature — If the equipment is installed in a closed
or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than the room ambient temperature. Therefore, install the extractor in an
environment compatible with the maximum ambient temperature specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is no compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have an overcurrent protection and supply wiring.
Use appropriate consideration of equipment nameplate ratings when addressing this
concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (for example, use of power strips).
