INTRODUCTION
Congratulations on your purchase of the DL DVI 2FO Extender. Your complete
satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.
The Gefen DL DVI 2FO Extender
The Dual Link DVI ber optic module extender with Virtual EDID extends dual-
link DVI up to 3300 feet (1 kilometer) to a display supporting resolutions up to
3840 x 2400 (WQXGA) using a two-strand 50/125µm laser-optimized multimode
(OM3) LC-terminated ber optic cable. Optical signal transmission provides
galvanic isolation and immunity to electromagnetic interference compared to
similar copper-based extension modules.
The Virtual EDID feature programs the display EDID into the Sender module to
ensure fast integration and compatibility between the source and the display.
The attractive and compact Sender and Receiver modules t neatly behind the
equipment for a clean installation, making it a great way to extend dual-link DVI.
How It Works
The Sender module plugs into the DVI source. The Receiver module plugs into
the dual-link display. Connect a two-strand multimode LC-terminated ber optic
cable from the Sender to the Receiver module. Plug the power supply into the
Receiver module and a vibrant Hi-Def picture will appear on your display.

OPERATION NOTES
READ THESE NOTES BEFORE INSTALLING OR OPERATING
THE DL DVI 2FO EXTENDER
• The ber optics cable must be treated carefully when connectors are
exposed. They are susceptible to dust which can contribute to loss of pixels.
• The DL DVI 2FO Extender works for all DVI displays and supports dual link
resolutions up to 3840 x 2400.
• The Sender module does not need to be powered externally unless the
source does not supply enough power through the DVI connector.
• Extension distance will depend upon the type of ber optic cable that is
used:
• Up to 3300 feet (1 kilometer) using two-strand OM3 multimode ber
optic cable.
• Up to 1650 feet (500 meters) using two-strand OM2 multimode ber
optic cable.
• Up to 1000 feet (300 meters) using two-strand OM1 multimode ber
optic cable.
• Supports DDWG standard for DVI monitors.

SENDER MODULE DESCRIPTIONS
1 Power Indicator
This LED will glow bright blue when the Sender module is powered.
2 Status Indicator
This LED will ash bright blue during the EDID programming procedure. See
page 9 for more information.
3 5V DC Power Receptacle
Connect the optional 5V DC power supply to this receptacle only if the source
does not supply enough voltage to power the Sender module.
4 LC Fiber Connectors
Connect a two-strand OM3 LC-terminated multimode ber optic cable from
the Sender module to the Receiver module. OM1 and OM2 multimode ber
cables are also supported. See page 2 for more information.
5 EDID Programming Button
See page 9 for more information on using this feature.
6 DVI Input
Connect this part of the Sender module to the DVI port on the computer.
IMPORTANT: In most cases the Sender module will not require a
power supply as long as the DVI source provides sufcient power
on pin 14 of the DVI connector. If the source does not supply
enough power to the Sender module (indicated by a ashing power
indicator), then connect the other included power supply to the
Sender module.
