RB-3GSDI-01 series
SD/HD/3G-SDI Video Converter
User’s manual (please read before installation)
1. Description
The RB-3GSDI-01 video digital optical converter uses an
all-digital fiber technology that allows transmission of SD,
HD or 3G-SDI video signals over one fiber optic strand
only at high-quality and for long reaches. RB-3GSDI-01
series offers transport of a single SDI video interface over
fiber optic. Besides the SDI interface, converters provide
a return RS-232/RS-485 interface path for control signals.
The single port series converters can also be installed in a
16 slot 19”, 2RU chassis with redundant AC power
supplies.

4. Installation
Package Contents: Converter, Power Adapter, and this
Manual
Please identify Transmitter and Receiver units in the
RB-3GSDI package. “-T”ending unit is Transmitter and
must be installed at the source of SDI signal, “-R”unit will
be installed at receiving end of the SDI video signal path.
Please connect optical fiber first and the SDI copper
connections before powering up the units. Check LED
lights to confirm proper connectivity has been
established. SDI signal should be available at remote end.
Only use the power supply provided with the converter
unit. Power adapter provides stable and filtered power
for the fiber converters; if adapter is lost please contact
vendor for a replacement part. A 3rd party AC adapter can
only be used if output voltage, polarity and power jack
connector are identical to the original AC adapter.

5. Safety
Please avoid exposure to water and do not install unit in
high humidity areas. Make sure all connectors (optical
and copper) are properly secured.
Please verify that power supplied is matching the input
required for operation:
- for AC adapter input：100~260V, 50~60Hz
- for DC input：5V/3A
Stop using devices if they have been exposed to water or
mechanical shocks affecting the physical form of the
units.
For outdoor installation please consider installing surge
protectors/lightning protection devices for the SDI
copper side interfaces.
6. Troubleshooting
The RB-3GSDI-01 series converters are simple plug and
play devices. There are very few adjustments to be made
for proper operation. Check below list for potential
adjustments:
- no light on POWER LED: please check power sources,
make sure AC power is available and properly connected.
Replace AC adapter with a similar one
-no light on SDI LED: please check copper SDI
connectivity: each SDI LED reflects local copper
connection; make sure each SDI LED is ON, the end
without SDI LED “ON”should be reset with a power cycle.
If connectivity is proper and LED is not turning on, please
use a different RB-3GSDI unit
- noise seen as “snow”effect on video quality: too much
fiber attenuation or weak/improper copper SDI
connectivity. Multiple potential causes:
▪normal fiber attenuation due to too long fiber
circuit or improper high attenuation fiber
splicing: please measure total fiber attenuation
with an OPM (optical power meter) and OLS
(optical laser source) to determine the level of
optical attenuation on your fiber circuit. If local
splicing is bad, replace or redo the fiber splices
▪fiber attenuation caused by fiber overbending:
please observe fiber path and reduce bends in
the fiber run
▪fiber attenuation caused by dirty optical
connectors: clean connectors with a fiber
cleaning pen (female) or fiber cleaning cassette
(male)
▪improper copper SDI connectivity: please check
quality of copper wiring
▪improper copper coaxial cable used: make sure
impedance of the video coaxial cable for SDI
interface is 75 Ohms
▪AC power interference: please avoid running AC
lines over or under the fiber extenders. Make
sure the AC power lines have proper grounding.
AC “noise”can affect quality of video signal
