IQOTR31 www.snellgroup.com Safety Information
Issue 1 Rev 1 Page 3 ©2012 Snell Limited
Safety Information
Warnings
Notes
• All lasers used in this product are Class 1, in
accordance with EN60825-1 as well as 21CFR
1040.10 and 1040.11.
• Laser light can be damaging to the eyes. Optical
fibers and uniters should be handled with great
care.
• The IQOTR31 is designed for use with Class 1 laser systems only. Ensure that all
outputs do not exceed Class 1 as doing so will impair the safety of the system and
may result in damage to the equipment.
• Active fibers should not be handled unless their source can positively be identified
as not exceeding Class 1 limits.
Note: • Optical uniters have shutters to prevent the ingress of dust. These shutters should
only be opened when connecting optical fibers.
• The ends of optical fibers should be cleaned with a liquid fiber cleaner, using a
cotton bud, to ensure that there is no dust present before they are plugged in (the
uniter is polarized).
• Do not disturb or handle the optical fibers.

An attenuator is required for short link distances (<15 km) and is fitted by default.
For link distances greater than 15 km, the supplied attenuator may be removed to
increase power. See “Attenuation” on page 13.

Issue 1 Rev 1 Page 12 ©2012 Snell Limited
4. Card Edge LEDs
The LEDs on the edge of the module indicate its operating status:
LED Color Description
POWER OK Green Indicates that a positive power supply is present.
CPU OK Green This LED will flash to indicate that the CPU is running.
ERROR Red This LED indicates board fault conditions.
When the unit is booting, this LED is illuminated, until the
SDI is enabled.
WARNING Yellow This LED is illuminated if one or more of the SDI inputs is
not valid or if the reference signal is missing when the unit is
set to Lock to Reference.
OK Green Indicates that the module is operating correctly.

IQOTR31 www.snellgroup.com Attenuation
Issue 1 Rev 1 Page 13 ©2012 Snell Limited
5. Attenuation
The IQOTR31 has 1550 nm transmission lasers. The lasers have a higher optical power
output than the 1310 nm variety. For link distances less than 15 km, this power is suffiecient to
saturate receivers.As a precaution, all units with 1550 nm transmission lasers are fitted with a
5 dBm attenuator. For distances greater than 15 km, it may be desirable to use the extra
optical power, in which case the attenuator can be removed.
To remove the attenuator:
1. Remove the card from the IQ enclosure.
2. Press down on the blue latch that holds the optical fiber connector in place and
withdraw the opitcal fiber.
3. Press down on the blue latch that holds the attenuator in place and remove withdraw
the attenuator from the SFP module.
4. Push the optical fiber connector directly into the SFP module. It will click when it is in
place.
5. Refit the card into the IQ enclosure.
Note: Take care not to touch the exposed glass tip of the optical fiber. If this does happen, clean
the exposed tip with an isopropyl alcohol wipe.

6. Controlling the IQOTR31 from the RollCall Control Panel
6.1 Information Window
The information window is displayed in the upper-right corner of each screen and displays
basic information about the input status, video, audio and reference status of the module.
6.1.1 Unit Status
The first two lines of the Unit Status display the input status, detected rate, and input selection
method for Input 1.
The third and fourth lines of the Unit Status display the same information for Input 2.
6.2 Inputs
The Inputs screen enables the type of input signal to be selected.
6.2.1 Input 1 SDI Rate (SDI IN 1) / Input 2 SDI Rate (RX IN 2)
•Auto: When selected, the unit will automatically detect and reclock any valid input
signal, and the detected rate will be displayed in the Unit Status.
If anything else is detected, the output will not be reclocked. If the On Input Loss /
Mute option is selected, the output will be muted; or, if the On Input Loss / Pass
option is selected, the output will be passed through.
•SD/DVB-ASI (270 Mb): When selected, the unit will reclock only SD/DVB-ASI (270
Mb) signals.
When selected, the On Input Loss controls are greyed out and are inactive. If any
other standard is applied to the unit, the output will be muted.

IQOTR31 www.snellgroup.com Controlling the IQOTR31 from the RollCall Control Panel
Issue 1 Rev 1 Page 15 ©2012 Snell Limited
•HD (1.5 Gb): When selected, the unit will reclock only HD (1.5 Gb) signals.
When selected, the On Input Loss controls are greyed out and are inactive. If any
other standard is applied to the unit, the output will be muted.
•3G (3 Gb): When selected, the unit will reclock only 3G (3 Gb) signals.
When selected, the On Input Loss controls are greyed out and are inactive. If any
other standard is applied to the unit, the output will be muted.
•Reclock Bypass: When selected, the unit will not reclock the input signal. If a
supported rate is detected, the Unit Status will display the detected rate, otherwise, ***
will be displayed.
• If the On Input Loss / Mute option is selected, the output will be muted whenever a
recoginized rate is not detected; or, if the On Input Loss / Pass option is selected,
any signal standard, frequency, etc… will pass through.
6.2.2 Output 1 / Output 2
•Mute: When selected, this option applies a mute on the output.
•On Input loss / Mute: When selected, if the Input signal is lost, the output signal will
be muted.
•On Input loss / Pass: When selected, if the input signal is lost, it will be passed
unchanged.
6.2.3 Fiber Optic Tx 1
This section displays the following information about the fiber optic output signal:
• Tx Wavelength
• Laser Bias
• Laser Bias State
• Tx Power
• Tx Power State
•Laser OFF: Selecting this option disables the laser.
•Laser OFF - On Input Loss: Selecting this option disables the laser if the input signal
is lost.
6.2.4 Fiber Optic Tx 2
This section displays the following information about the fiber optic input signal:
• Rx Power
• Rx Power State
Note: These controls only apply to the SDI outputs on the BNC. The laser output is controlled by
the Laser OFF and Laser OFF - On Input Loss controls.
Note: These controls only apply to the fiber optic output signal. The SDI outputs on the BNC are
controlled by the Mute and On Input Loss - Mute controls.
When the unit is forced to a particular standard, the laser controls are not grayed out, and
the laser will still be active if an incorrect standard is applied unless Laser OFF - On Input
Loss is selected.

6.3 Memories 1-16
The Memories screen enables up to 16 setups to be saved and recalled later. The default
memory names can be changed to provide more meaningful descriptions.
6.3.1 Saving a Memory Name
To save settings:
• In the Save Memory column, select a memory location, and then click Save. The
current settings are saved and the memory appears in the Recall Memory column.
6.3.2 Changing a Memory name
• In the Save Memory Name field, type the new memory name, and then click S. To
return the memory to its default value, click the preset button (P).
Use the Recall Memory function to recall the settings saved in a memory location.
Last Recalled Memory displays the most recently recalled memory. An asterisk next
