Module Description
The IQOTX3x modules are 1310nm or 1550nm fiber optic transmitters for 3G/HD/
SD-SDI signals. The units are available in single or dual channel versions
handling up to two 3G/HD/SD-SDI sources. Single channel versions have
additional flexibility with one or two optical outputs and four reclocked electrical
outputs. Suitable for applications where 3G/HD-SDI signals need to be
transported over long distances within a facility or between sites, optical links
remove the distance constraints of copper cabling at high frequency data rates
such as 3Gbit/s.

Warnings
•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 IQOTR30/31/32/33/34/35/36 is designed for use with Class 1 laser sys-
tems only. Ensure that all outputs do notexceed 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 thier source can positively be
identified as not exceeding Class 1 limits.
Notes
•
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.
• 1550nm Tx on IQOTX33, IQOTX34, IQOTX35 and IQOTX36 Modules
An attenuator is required for short link distances (<15km) and is fitted by
default. For link distances greater than 15km, the supplied attenuator may be
removed to increase power.
See “Attenuation” on page 11.

Attenuation
The IQOTX33/34/35/36 modules have 1550nm transmission lasers, which have
a higher optical power output than the 1310nm variety present on the IQOTX30/
31/32 modules. For link distances less than 15Km, this power is suffiecient to
saturate receivers. As a precaution, all units with 1550nm transmission lasers are
fitted with a 5dBm attenuator. For distances greater than 15Km, 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.
Takecare notto touch theexposed glass tip ofthe optical fiber.
If this does happen, clean the exposed tip with an isopropyl
alcohol wipe.

Controlling the IQOTX3x from the RollCall
Control Panel
Unit Status Information about the status of the unit is displayed in the Unit Status section on
each RollCall Control Panel screen.
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.

Version 1 Issue 2 www.snellgroup.com IQOTX30/31/32/33/34/35/36
Page 13
Input The input screen enables the type of input signal to be selected.
Input 1 SDI Rate (SDI IN 1)
•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.
•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.

Version 1 Issue 2 www.snellgroup.com IQOTX30/31/32/33/34/35/36
Page 14
•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.
Output 1
•Mute: When selected, this option applies a mute on Output 1.
•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.
Input 2 SDI Rate and Output 2 (IQORX30 only)
These options are the same as the Input 1 SDI Rate and Output 1 options but are
applied to Input 2 and Output 2.
Fiber Optic Tx 1 / Tx 2
The Fiber Optic Tx 1 and Fiber Optic Tx 2 areas display information about fiber
optic transmission and provide options to disable the laser. The information
displayed is:
• Tx Wavelength
• Laser Bias
• Laser Bias State
• Tx Power
• Tx Power State
This information is also recorded by the module’s log functions.
•Laser OFF: Selecting this option disables the laser and fiber optic transmis-
sion.
•Laser OFF - On Input Loss; Selecting this option disables the laser and fiber
optic transmission if the input is lost.
These controls only apply to the SDI outputs on the BNC. The
laseroutputis controlledby theLaser OFFandLaser OFF- On
Input Loss controls.
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.
