Safety and Notice
• Do not bend the power cord by force, or do not put heavy objects on the power cord to
prevent breakdown. It can cause a fire.
• Do not touch the power plug with wet hands. You may be struck by electricity. Insert
the power plug firmly to avoid shaking. If not inserted firmly, fire hazard may occur.
• Use mains power with correct voltage. Not doing so may result in unit damage.
• Do not insert metallic objects (hair pin or ironware) or combustible foreign objects
(match, paper and so on) into the terminal hole, or drop the terminal. It may cause a fire
and an injury by electrical shock.
• Don’t put heavy objects on top of the product. It may cause malfunction.
• Do not disassemble, repair or modify. It can cause a fire and an injury by electrical shock
due to abnormal operation.
• Place the product in an even and stable location. If the product falls down or is dropped,
injury and/or malfunction may occur.
• Do not spray water on the product. It may cause a fire and an injury by electrical shock.
Scrub the product surface softly with a dry towel.
• Do not twist or pull the optical cable by force. It can cause malfunction.
• Do not look directly at the light coming from the fiber optic connectors and cable as it is
harmful to the eyes.
• Use the unit in environmental temperatures between 0°C and +50. Not doing so may
result in unit malfunction.

Overview
The USXT² 12G-SDI extender is a rugged, tour grade fiber optic extender for transmitting
12G signals up to 4K @ 60Hz.
The Transmitter TX unit features a 12G-SDI Loop out BNC and the Receiver RX is
equipped with dual 12G-SDI outputs. The USXT² provides info on the used bandwidth
thanks to the multicolor LED found next to the BNC bulkheads.
Power is provided through Neutrik powerCON TRUE1 TOP connectors (mains power ca-
bles included with Belgian Schuko plug).
The USXT² accepts standard BNC cables (although we recommend 4K 12G-SDI rated coax
cable, contact us for more information)
The extender is fitted with Neutrik opticalCON DUO chassis for the optical link allowing
for a robust connection between sender TX and receiver RX. Common LC duplex OM3/
OM4 or singlemode fiber may be used. However, we strongly recommend to use Neutrik
opticalCON DUO (or opticalCON DUO X-TREME) for the fiber link.

Setup
1. Connect the 12G-SDI source to the USXT² Transmitter unit (“SDI IN”).
Note:
We recommend using 12G certified coax cables with UHD BNC connectors to maintain maximum
performance stability not exceeding 30m in length.
2. Optionally you can loop out the input by connecting a display or interface (“SDI
LOOP OUT”)
3. Plug the power cable in the USXT² Transmitter’s powerCON TRUE1 TOP chassis
(“Power”).
4. Connect the fiber cable to the USXT² Transmitter’s Neutrik opticalCON DUO chassis
(“fiber out”).
Note:
Multimode or Singlemode fiber may be used.
Consult “Technical Specifications” (p.6) for maximum transmission distances.
You can also use opticalCON LITE DUO or standard Duplex LC optical fiber.

4. Connect your 12G-SDI interface to the USXT² Receiver unit (”SDI OUT 1”).
Note:
A secondary output is provided. Both outputs can be used simultaneously.
5. Plug the power cable in the USXT² Receiver’s powerCON TRUE1 TOP chassis
(“Power”).
6. Connect the fiber cable to the USXT² Receiver’s Neutrik opticalCON DUO chassis
(”FIBER IN”).
Note:
Multimode or Singlemode fiber may be used. Consult “Technical Specifications” (p.6) for maximum
transmission distances.
7. Check the status LED:
If everything is connected correctly, the LED will show the SDI signal status:
• Off -> No Input
• Red -> SD-SDI
• Green -> HD-SDI
• Blue -> 3G-SDI
• Yellow -> 6G-SDI
• Purple -> 12G-SDI

Maintenance
Optical fiber connections are capable of transmitting very high bandwidths but are prone
to dust and dirt. Therefore we strongly recommend a good maintenance after every use.
There are a couple of simple and cost effective ways to easily clean both the cables and
connectors on the XT² extenders. These cleaning tools are available through Belram.
Cleaning the USXT² optical connector(s)
Required tooling:
Instructions:
1. Remove protective cap from Dry Cleaner.
2. Insert the tip of the Dry Cleaner in LC slot “a”.
3. Push down on the Dry Cleaner 4 - 5 times.
4. Remove Dry Cleaner and repeat for LC slot “b”.
5. The optical connector has been cleaned.
6. Repeat above steps if necessary.
• Dry Cleaner 1,25mm

Required tooling:
Instructions:
1. Remove protective cap from the opticalCON DUO
connector.
2. Click the FOCD-STD onto the connector.
3. Insert the Dry Cleaner’s tip into the ferrule hole of
the FOCD-STD.
4. Push down on the Dry Cleaner 4 - 5 times.
5. Repeat for the remaining ferrule hole of the
FOCD-STD.
6. Repeat above steps if necessary.
