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 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 12 miles (20 km)
over either single-mode or multi-mode fiber 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 fiber cable and converts it to an SDI signal.
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 3GSDI FIBER OPTIC EXTENDER
• The use of an intermediate cable or adapter is not recommended. Additional
coupling devices may deteriorate the signal transmission.
