Instruction Manual – DXLink Fiber™ Transmitters and Receivers, Duplex
ESD Warning
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before
touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be
followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive
smocks, and conductive work mats are specifically designed for this purpose.
Anyone performing field maintenance on AMX DXLink Fiber equipment should use an appropriate ESD field service
kit complete with at least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another
ground cord. These items should not be manufactured locally, since they are generally composed of highly resistive
conductive materials to safely drain static charges, without increasing an electrocution risk in the event of an accident.
ESD protective equipment can be obtained from 3M™, Desco®, Richmond Technology®, Plastic Systems®, and other
such vendors.

Applicability Notice
The information in this manual applies to the AMX DXLink Fiber Transmitters and Receivers, Duplex listed in the
table below. These units handle simultaneous, bidirectional data transfer. They are available in both multimode and
single mode models (which differ only in respect to their transceivers which support different cable lengths).
Throughout this manual, the phrase “DXLink Fiber units” will be used when referring generically to all four of the
DXLink Fiber, Duplex product models.
When referring to specific Duplex models, they will be described as follows:
Multi-Format MMF-D TX*
HDMI MMF-D RX*
Multi-Format SMF-D TX**
HDMI SMF-D RX**
* MMF-D = multimode fiber - duplex
** SMF-D = single mode fiber - duplex
DXLink Fiber Transmitters and Receivers, Duplex
^ On the rear of both Transmitter units, the number will be FG1010-36X, indicating they share a common metal box design.
^^ On the rear of both Receiver units, the number will be FG1010-56X, indicating they share a common metal box design.
The multimode and single mode fiber optic transceivers allow for in-the-field replacement.
Compatibility Note: In Enova DGX systems using DXLink Fiber technology – the DXLink Fiber Input Board
and its DXLink Fiber TX, Duplex must have the same type of fiber optic transceivers: either multimode or
single mode. The same holds true for DXLink Fiber Output Boards and the DXLink Fiber RX, Duplex units.
Important: Use of a DXLink Fiber Transmitter and Receiver as a standalone pair
will be supported in a future firmware upgrade.

Product Notes
Fiber Optic Transceivers
The DXLink Fiber units use SFP+ fiber optic transceivers.* Fiber optic transceivers are self-contained modules that send
and receive optical signals over fiber cable. These fiber optic transceivers are either multimode or single mode and must
be wired with the corresponding cable type.
* SFP+ = enhanced small form-factor pluggable fiber optic transceiver rated at 10 Gbps transmission data rate.
Note: The types of fiber optic transceivers used in DXLink Fiber units are referred to as “multimode” and
“single mode,” which indicate the maximum length of the fiber optic cable that can be used. In addition, the
Transmitters and Receivers support modes that can be determined during setup to handle the system
architecture, accommodate networking needs, and process video signals (see page 26).
Transceiver Types / Cable Types / Cable Runs
The type of SFP+ fiber optic transceiver helps determine the maximum length of cable runs possible. Cable quality is
also a determining factor.
All DXLink Fiber units are designed for transmission of an HDMI signal over fiber optic cable.
Both multimode and single mode transceivers on DXLink Fiber units support bidirectional communication
(Bidirectional Mode).
Bidirectional communication over DXLink Fiber includes transmission of the following:
Digital video and audio
Native NetLinx control
IR
RS-232
USB keyboard and mouse
Ethernet (100 Mbps)
OSHA Directive
The OSHA Technical Manual (at https://www.osha.gov/dts/osta/otm/otm_iii/otm_iii_6.html) under “VI. Control
Measures and Safety Programs” states: “Direct exposure on the eye by a beam of laser light should always be avoided
with any laser, no matter how low the power.”
Transceiver Disposal
Important: If disposal of transceivers is necessary, dispose of them as mandated by your area or country
guidelines.

Warning: DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive below).

Multimode SFP+ Fiber Optic Transceiver
A multimode SFP+ fiber optic transceiver is used for the Multi-Format MMF-D TX and the HDMI MMF-D RX.
Depending on the transceiver model, it will have a latch that is black or a black label on the latch top with white triangles
showing data flow direction.
The multimode SFP+ fiber optic transceiver requires multimode fiber optic cable, which allows numerous optical waves
to traverse the optic core. Multimode fiber optic cable has a significantly larger optical core (which results in a higher
dispersion rate) and results in comparative shorter distance optical runs than the single mode cable.
Single Mode SFP+ Fiber Optic Transceiver
A single mode SFP+ fiber optic transceiver is used for the Multi-Format SMF-D TX and the HDMI SMF-D RX.
Depending on the transceiver model, it will have a bright blue latch or a blue label on the latch top with white triangles
showing data flow direction.
The single mode SFP+ fiber optic transceiver requires single mode fiber optic cable, which allows a single optical wave
to traverse through the optic core. Single mode fiber optic cable has a significantly smaller diameter optical core than
multimode fiber optic cable and is generally associated with longer distance transport capabilities.

Instruction Manual – DXLink™ Fiber Transmitters and Receivers, Duplex
Multi-Format MMF-D TX and Multi-Format SMF-D TX
The DXLink Fiber Transmitters, Duplex receive an HDMI signal or analog video signal (composite, Y/C, Y/Pb/Pr,
RGB, RGBS, or RGBHV) and an audio signal from a source device. The audio can be either digital audio embedded
with the HDMI or analog stereo audio.
Either analog or digital video is transmitted out of the fiber optic transceiver. The active video selection is made using
one of two methods:
Automatic – selects digital video as the priority video input or analog video when digital video is not present.
Can be set to treat either the digital or analog video as the priority, which then defaults to the opposite if the
primary is not present.
Active SEND_COMMAND video input selection from a bound NetLinx Central Controller (usually the
integrated Central Controller on the Enova DGX).
Both the video and audio are transported over fiber optic cable to an Enova DGX Digital Media Switcher. The unit also
has a local HDMI output connector on the front for sending the video signal from the source directly to a local
destination device. This local HDMI output connection supports the same input resolutions contained in the first table in
“Appendix E - Supported Input Resolutions” (see page 119).
The 232 port (RS-232) on the Transmitters supports bidirectional serial data via the fiber optic cable to/from the
232 port. In addition, the Transmitters have IR ports, which also send data via the fiber optic cable.
HDMI MMF-D RX and HDMI SMF-D RX
The DXLink Fiber Receivers, Duplex feature SmartScale®Technology (integrated EDID output scaling) to ensure an
appropriate output resolution, plus they support a Manual (override) option for setting up custom resolutions and a
Bypass option (see page 50).
The DXLink Fiber Receivers receive an HDMI signal and an audio signal over fiber optic cable from a DXLink Fiber,
Duplex Output Board on an Enova DGX Switcher. They then send the signal on to the destination. The audio output can
be either digital audio embedded with the HDMI signal or analog stereo audio (if the signal originated as a 2 channel
audio format).
The 232 ports (RS-232) support bidirectional serial data via the fiber optic cable, which connects the DXLink Fiber
TX/RX units and the Enova DGX Switcher.
Note: If a DVI-D signal is used (via a DVI-to-HDMI cable), the advanced audio support from HDMI will not be
available out the Receiver.
Note: DXLink Fiber units support several different modes which are available for system setup and use. Brief
explanations of the modes are provided in the section “Quick Reference Tables for Modes” on page 26 along
with page references to detailed information.
