INTRODUCTION
Congratulations on your purchase of the 3GSDI Fiber Optic Extender. Your com-
plete satisfaction is very important to us.
GefenPRO
In the realm of video distribution, certain features are invaluable in a commercial
or broadcast environment. Accommodations such as a build-in power supply
and flat black rack-mount enclosures set GefenPRO apart from our traditional
products. Complex distribution units allow for professional DVI, 3G-SDI, and
HDMI signals to be routed and converted easily and seamlessly, while being
backed up by a renowned and dependable technical support team. Gefen invites
you to explore the GefenPRO product line and hopes that you find the solution
that fits your needs.
The GefenPRO 3GSDI Fiber Optic Extender
The GefenPRO 3GSDI Fiber Optic Extender is a miniature digital video data
transport system over fiber optic cable supporting 1080p for 3G-SDI and HD-
SDI. It converts a one-channel SMPTE-424M 3G-SDI, SMPTE-292M HD, or
SMPTE-259M serial digital video signal over extended distances up to 19 miles
(30 kilometers).
How It Works
The Sender receives the SDI input signal and converts the SMPTE-424M / 292M
/ 259M SDI signals to optical data. The Receiver unit collects the optical data
from the fiber cable and converts it to an SDI signal.

TROUBLESHOOTING
No picture / display shows a blank screen
• Ensure that all jacks that are used by the 5 V DC power supplies are firmly
connected.
• Ensure that the SDI connector is firmly plugged in to the SDI source and SDI
display. Ensure that the Sender and Receiver module parts are connected to
the SDI source and SDI display, respectively.
• Check if the SDI source and SDI display are powered on and properly
booted.
• Reset the system by unplugging and reconnecting the Sender SDI module
or Receiver SDI module. Re-boot the system while connecting the 3G-SDI
Fiber Optic Extender.
• Verify that the fiber cables are not damaged.
Picture is distorted or contains noise
• Verify the quality of the SDI source and check the length of the fiber cable.
