Safety Considerations
Users should read the complete instruction manual to familiarise
themselves with the operation of the OWT before attempting to
operate it.
Power Supplies
For OWT’s with an external supply, the voltage of the external supply should be 10-
14V DC (12V Nominal). Exceeding the supply voltage limit may damage the OWT and
will invalidate the warranty.
Positioning the OWT
Only use the OWT on a solid, level surface. e.g. a lab bench.
Ensure the overhang of the OWT is approximately 75mm from the edge. There are
rubber feet positioned approximately 100mm away from the front face of the OWT.
Do not situate the OWT any further forward than these rubber feet, or it may
become unstable.
Top Cover Interlock
The OWT will not function unless the top cover is in the fully down position. If during
a test the top cover is lifted the test will immediately stop and the DUT will stop
rotating.
Emergency Stop Button
The emergency stop button is located on the top side of the OWT. If a situation
arises that requires an immediate stop to the test press the button. The test will
immediately stop and the DUT will stop rotating. To reset the button to allow further
testing, turn the button to release it.
Environmental
Do not attempt to use the OWT in an abnormally hot or humid environment, or in
proximity to explosive gas, vapour or dust.
Servicing
Do not remove any covers from the OWT without express permission of Ktizo
Consulting. Doing so will invalidate both calibration and warranty. There are no user-
serviceable parts inside the OWT. Refer all servicing to Ktizo-approved personnel. Do
not use the OWT if it appears damaged.

Introduction
Optical fibre technology is everywhere. It has enabled the explosive growth of on-
line entertainment and business in the last decade.
One of the greatest challenges facing designers of optical fibre
systems is aligning the tiny fibres with each other. This is
particularly difficult in connectorised systems where fibres may
be mated and de-mated repeatedly.
The challenge is especially great when the fibre is “wiggled”
around. This can happen during installation, or when cabling is
disturbed. In a poorly designed system, several dB of light power
can be lost. This can be enough for an optical system to fail.
Cisco Systems Inc. defined a standard which has been widely adopted throughout
the industry.1 It applies to SFP and other similar optical platforms.
In short, it states that a load should be applied to the patchcord while the DUT is
rotated through 360° at a speed of 4 rpm. The test should be conducted with no
load, with 0.25lb load and with 0.5lb load. Throughout the test, the optical loss in the
system should not exceed 1dB.
Ktizo's Optical Wiggle Tester is a complete turn-key solution to optical wiggle testing.
It conforms to Cisco's specification but is also flexible enough to allow more
thorough testing to help investigate potential alignment problems.
The Optical Wiggle Tester provides a reliable, consistent and easy-to-use way to
analyse wiggle test performance.
The Optical Wiggle Tester is highly configurable and can be used with all types of
optical transceiver modules, TOSAs and ROSAs.

Start Button – pressing this button starts the Wiggle Test program that is
currently loaded.
Stop Button – pressing this button at any time during a test run will abort
the test run.
Save Data Button – If this button is pressed, the current data will be saved.
A raw data file is saved, and also an image of the wiggle test results graph.
Find Zero Degrees Button – If this button is pressed, the tester will
automatically find its zero-degrees position, ready to start a new test run.
This is useful particularly when a test run is stopped half-way through for
some reason.
Status Panel
This set of indicators is updated during test runs and when the tester is at idle.
Power to DUT – This is lit when electrical power is applied to the DUT
Optical Overload – This indicator is only used in systems that measure ROSA optical
power. It is lit when the current produced by the ROSA RSSI is too high for the
tester’s ADC to measure accurately. If this indicator lights up, either reduce the
optical power, or contact Ktizo for more information on altering the ADC range.
Interlock Open – This is lit if the clear lid is opened. If it is lit during a test run, the
motor will be automatically stopped, and the test run will be aborted.
Emergency Stop Activated - This is lit if the emergency stop button is pressed. If it is
lit during a test run, the motor will be automatically stopped, and the test run will be
aborted.
At Zero Degrees – This is lit when the tester is at its zero degrees position.

ROSA Calibration
For systems that include ROSA test capability, this process must be carried out prior
to any testing.
The Optical Wiggle Tester plots optical power as follows:
Power (μW) = ADC value * μW per ADC step
This calibration process sets the value of μW per ADC step.
The native units of optical power in the Optical Wiggle Tester are μW. All optical
power calculations are performed with units of μW internally. If the user has
selected reporting in dB, this is derived from the optical power in μW as the final
process before displaying the data.
Go to:
Action > Calibrate Rx
1) A dialogue box opens, showing an indication of the ADC value. If the ADC value is
between 10% and 90% of full-scale, the bar is green. Press the green “tick” to
continue the calibration process. Pressing the red “cross” will abort and retain the
previous calibration state.
2) At this stage, the patchcord should be removed from the ROSA and connected to a
calibrated optical power meter. Read the optical power and enter it into the Optical
Power box. The units (dBm or uW) are defined in Settings > Report in uW/dBm.
Press the green “tick” to continue.
At this stage, the system calculates the new value of μW per
ADC step
- 13 -
Copyright 2009 Ktizo ConsultingOptical Wiggle Tester – instruction manual v1.1 June 09
3) When the calibration is complete, a message is displayed showing the new value
of μW per ADC step, which is equivalent to the measurement resolution.

Motor Calibration
Motor calibration should only be necessary at delivery or if the motor appears to be
turning more or less than 360 degrees during operation.
The Optical Wiggle Tester relies on timing to ensure optical power samples are taken
at the appropriate angular interval, and that the motor stops at the correct position.
For example, to rotate through 360 degrees, at 4 rpm, taking samples every 6
degrees:
t = 0 ms motor starts. Initiate optical power sample (0 degrees)
t = 263 ms initiate optical power sample (6 degrees)
t = 526 ms initiate optical power sample (12 degrees)
through to…
t = 15526 ms initiate optical power sample (354 degrees)
t = 15789 ms initiate optical power sample (360 degrees). Motor stops.
Therefore the time taken for the motor to rotate through 360 degrees is very
important. To calibrate the motor rotation time, go to:
Action > Calibrate Motor
Follow the on-screen instructions.
- 15 -
Copyright 2009 Ktizo ConsultingOptical Wiggle Tester – instruction manual v1.1 June 09
Manual Motor Control
The motor can be rotated manually using the Manual Control dialogue box. Go to:
Actions > Manual Control
Speed and direction can be adjusted. The motor will
rotate when the Start Button is pressed.
When the motor reaches zero degrees, the indicator
lights.
The motor can also be rotated by hand after lifting the clear cover.

Holes
Insert the two M4 cap screws into the holes of the mount assembly. Offer the
assembly up to the base plate and align it with the assembly mount holes. Using the
Allen key provided tighten the cap screws and fix the assembly into position.
Manually rotate the base plate to gain access to a side mount screw. Adjust the
screw position until the screw end face just touches the evaluation board mount
block.
Caution – damage to the DUT may occur if the screw is over tightened at this stage.
Rotate the base plate to gain access to the other side mount screw. Adjust the screw
position so that the screw end face touches the block.

Testing
Preliminaries
Insert an appropriate patch cord into the optical connector port and connect the
other end to an optical source of known power.
Run the program and ensure ROSA calibration is complete.
Starting a test run
Press the start button
The software will perform the test on the first step of the program. A dialogue box
will appear, similar to the one below, instructing the user which weight (or none) to
attach.
The wiggle test results will then be plotted on the wiggle test results graph.
Adding weights to the patchcord
Some program steps may request weight to be added to the patchcord.
To add the 0.25lb (0.113Kg) weight…
Starting at a position approximately 200mm from the inserted end wind the patch
cord around the mandrel making sure all the mandrel channels are used. Using the
wire tie wrap supplied wrap the two ends of the patch cord as shown below
sufficiently tight to prevent any slippage of the patch cord. The combined weight
of the mandrel and metal insert is 0.25lbs (0.113Kg).

Patchcord Calibration Methods
There are 3 methods of arranging the patchcord and calibrating the system. There
are advantages and disadvantages to each method.
1) Standard
After the calibration is complete, the optical path between the source and the DUT is
never disturbed.
Advantages: * Accurate power measurements
Disadvantages: * As the patchcord is wound around the mandrel, it tends to
twist
2) Ignore mandrel
The patchcord is wound around the mandrel, with the 0.25lb weight removed,
before the patchcord calibration is done.
Advantages: * Accurate power measurements
* The patchcord never becomes twisted
Disadvantages: * The weight of the mandrel 26g [0.05732lbs] is ignored in 0lb
test steps. i.e. A very small load is applied in 0lb steps.
3) Automatic compensation.
After the 0lb test step is complete, the patchcord is removed from the DUT** to allow
for easy winding around the mandrel. When the patchcord is re-connected to the
DUT, the software automatically compensates for any power variation caused by
breaking the optical connection.
To set this option, go to Settings and select the Recalibrate after first step option.
After the first step is complete, the software will request the user to disconnect the
patchcord from the DUT and attach the
mandrel. Then the patchcord should be re-
connected to the DUT. It is important that
there is no strain on the patchcord at this point
because the software then re-measures the
optical power and uses that to re-calibrate the optical path.
The software shows the change in optical power
due to breaking the optical path. Ideally this
should be 0μW. If the user is happy with the
change in power, click on the green tick. All
subsequent optical power measurements are
compensated by this amount. If the red cross is clicked on, the program will abort.
**
Alternatively, a back-to-back optical coupler can be used in the optical path to provide a way to uncouple the
light without disturbing the DUT.
- 22 -
Copyright 2009 Ktizo ConsultingOptical Wiggle Tester – instruction manual v1.1 June 09
The software will then ask the user to allow the
mandrel to hang freely. The remainder of the test
steps are now completed.
Advantages: *Optical path can be broken after the first program step.
*The patchcord never becomes twisted
*No extra weight applied in 0lb tests
Disadvantages: *Optical power measurements in program step 2 onwards are
compensated for any power change in the optical path.
Therefore the optical powers displayed on the results graph
are not actually offset values – but they are correctly
proportioned in relation to the 0lb test.

Calibration & reporting tab
Report in dB(m) [µW] – This selects whether data is displayed in the Results Graph in
dBm or µW. It also affects the units of the Y-axis on the results graph, the saved data
in the .csv file, and the units used in calibration.
Report absolute [relative] power – If absolute power is selected, the Results Graph
shows data in absolute units. i.e. in µW or dBm. If relative power is selected, a single
power measurement is taken at the start of the first program step, before motor
rotation starts. This is then used as a baseline for all subsequent measurements
during that program run. Values of power are then reported as Delta µW, or dB.
Include date and time in filename – If selected, the date and time of the start of the
program run are appended to the file name of any saved data.
Recalibrate after first step – the function of this option is described in detail in the
section ROSA Testing. It is only valid for systems that are capable of testing ROSAs.
Cursors tab
Include zero power marker? - If this setting is turned on, a thin line is displayed along
the y=0 axis.
Include test limits? - If this setting is turned on, two thicker lines are displayed,
equidistant to the y=0 axis. The limit can be adjusted if necessary to match the
application of the DUT.
Zero power

Test limits
When the Report absolute [relative] power setting is set to absolute, none of the
cursors appear until the first optical power measurement is taken. The zero power
marker is then set to the initial power, and the test limits are set either side of it.
When the Report in dB(m) [uW] setting is changed, the test limits are set to a
default value, with the new units.
