INTRODUCTION
Congratulations on your purchase of the 3GSDI Fiber Optic 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 3GSDI Fiber Optic Extender
The Gefen 3GSDI Fiber Optic Extender is a miniature digital video data transport
system over fi ber optic cable supporting 1080p for 3G-SDI and HD-SDI. It
converts a one-channel SMPTE-424M 3G-SDI, SMPTE-292M HD, or SMPTE259M serial digital video signal over extended distances up to 12 miles (20 km)
over either single-mode or multi-mode fi ber optic cable.
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 fi ber cable and converts it to an SDI signal.

• Ensure that all jacks that are used by the 5V DC power supplies are fi rmly
connected.
• Ensure that the SDI connector is fi rmly 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 reconecting the Sender SDI module or
Receiver SDI module. Re-boot the system while connecting the 3GSDI Fiber
Optic Extender.
• Verify that the fi ber cables are not damaged.
Picture is distorted or contains noise
• Verify the quality of the SDI source and check the length of the fi ber cable.
The 3GSDI Fiber Optic Extender will work up to a distance of 12 miles
(20km) using single-mode fi ber.
