INTRODUCTION

Congratulations on your purchase of the 3GSDI Fiber Optic Extender. Your com­plete 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 fl at 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 fi nd the solution
that fi ts your needs.

The GefenPRO 3GSDI Fiber Optic Extender

The GefenPRO 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
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 fi ber cable and converts it to an SDI signal.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 3GSDI FIBER OPTIC EXTENDER

• The GefenPRO 3GSDI Fiber Optic Extender will connect two 3G-SDI
devices using an ST-terminated fi ber cable to a distance of up to 12 miles
(20 kilometers.). HD-SDI can be extended up to 19 miles (30 kilometers).
The input has automatic equalization and the output is automatically re­clocked.

• 3G-SDI can be extended up to 1640 feet (500 meters) when using multi­mode fi ber.

• The use of an intermediate cable or adapter is not recommended. Additional
coupling devices may deteriorate the signal transmission.

• 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 reconnecting the Sender SDI module
or Receiver SDI module. Re-boot the system while connecting the 3G-SDI
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 extend 3G-SDI up to a distance of 12
miles (20 kilometers) using single-mode fi ber. HD-SDI can be extended up
to a distance of 19 miles (30 kilometers) using single-mode fi ber. 3G-SDI
can be extended to a maximum of 1640 feet (500 meters) using multi-mode
fi ber.
