1. INTRODUCTION
The 3G-SDI 4 by 4 Switcher/Splitter allows SD-SDI, HD-SDI and 3G-SDI
signals to be switched from up to four SDI sources and split to four
simultaneous SDI outputs while ensuring high bit rates of 2.970 Gbit/s
to give you high bandwidth signal transmission without signal loss over
long distances and can be controlled via IR or RS-232.
2. APPLICATIONS

5. FEATURES
• Switch between four 3G-SDI input sources and split the output to
four 3G-SDI displays simultaneously
• Operation at 2.970 Gb/s, 2.970/1.001 Gb/s, 1.485 Gb/s,
1.485/1.001 Gb/s and 270 Mb/s
• Supports SMPTE 425M (Level A and Level B), SMPTE 424M, SMPTE
292M, SMPTE 259M-C
• Provides equalized and re-clocked transmission
• Control via RS-232, IR remote control (supplied) and on-panel
buttons
• Supports signal input and output distances of up to 300 m for SD
signals, 200 m for HD signals and 100 m for 3G signals.
Note: Tested with Belden 1694A Cable. Operating distances may vary
