Test Procedures Overview
The following section will provide an overview of the workow and recommended procedures for
each test that can be performed with the TTK 720 kit. Some procedures may have more importance
placed on them by the carrier: please use these procedures only as a guideline. Wireless carrier
requirements supersede ODM’s recommended procedures in all circumstances.
This section explains how to properly maintain the TTK 720 test kit components between uses.
VIS 300C charging, equipment cleaning, and storage are discussed.
Proper Equipment Care Between Uses
1
When arriving at a new test site or when starting a new project, the user should create a new “Project
Folder” on the VIS 300C unit. This stores all relevant site information (scope images, loss readings, etc.
in one place. This section covers setting up for a new test site.
Creating a New Folder in VIS 300C Software
2
Fiber inspection should be performed before making any connections onsite. Analysis and saving of
images may be required for closeout packages. This section explains how to inspect and clean ber.
Fiber Scoping
3
Also known as “insertion loss” or “ber sweep” testing, dB loss testing allows the technician to validate
that all ber pairs are in working condition. Saving of dB loss test results may be required for closeout
packages. This section explains the necessary steps for testing ber.

An onboard red laser allows users to verify proper continuity of ber cables. This is a troubleshooting
task only. This section gives an overview of the VFL functionality.

1a - Charging the VIS 300C
The VIS 300C charger comes in two pieces. See diagram below. The cable on the right will be
plugged into the power brick to create the charging device.
Allow the VIS 300C to charge fully between uses. The VIS 300C can be used while charging;
please be aware that an internal fan may activate to regulate temperature. 4-5 hours battery
life typical for a single charge.

1b - Cleaning the DLS 355
The DLS 355 laser source is a high-end test laser, capable of outputting 1310 and 1550nm
wavelengths. The output port of this unit utilizes a physical connection, which means that it
can become soiled if used improperly. When needed, the DLS 355 adapter may be removed for
inspection and cleaning of the ber ferrule.

Remove adapter by
unscrewing until it spins
freely, then pull o.
Inspect ferrule with
VIS 300C and clean
with appropriate tools.
Always replace adapter.
Regular inspection and cleaning of the output port of the DLS 355 may not be necessary if
appropriate procedures are followed. Always inspect test jumpers before they are plugged into
the DLS 355 and store it properly to ensure continued performance.

1c - Inspecting and Cleaning Fiber Jumpers and Loopback
Special care should be taken to ensure the continued function of all test jumpers and
loopbacks. A regular inspection and cleaning regimen will keep kit components functional for a
longer period of time.

indicates a ber ferrule that should be
inspected and cleaned between uses.

1d - Equipment Storage
All equipment should be stored in the airtight case provided by ODM. Keep the case in a cool,
dry location and remove battery from the DLS 355 if it must be stored for over 6 weeks.

3b - Inspect the Fiber
ODM’s automated analysis feature makes short work of ber inspection. Follow these steps to
determine if a ber is acceptable for use.
Insert the ber ferrule into the inspection tip on the VIS 300C inspection probe as shown above. The
ferrule should be inserted fully, until it “stops” inside the tip.
Use the focus knob on the inspection probe to obtain an appropriate focus level. The focus knob is
the larger of the two knurled knobs on the end of the probe.

Once focused, the software will automatically center the ber core onscreen. If a closer view of the
live image is desired, touch the “+ Zoom” button in the bottom left corner of the screen. To go back
to the original zoom level, touch the “- Zoom” button. Zoom/Magnication has no eect on the nal
analyzed image.
AC 089 One-Click Cleaner
“Dry Clean Method”
Insert ber ferrule into one-click cleaner. Press
ber and cleaner together until a click is heard.
There is no need to rotate the cleaner. Re-inspect
the ber after one click to see if debris has been
cleared from the endface.
AC 092 Pad and Fiber Wash Pen
“Wet/Dry Clean Method”
Isolate a single wipe on the pad. Press liquid pen onto the wipe to soak the top 1/3. Press the ber
ferrule at a 90o angle into the wet spot on the pad. Drag the ber ferrule from the wet part of the wipe
to the dry part of the wipe. Re-inspect the ber to see if debris has been cleared from the endface.

3c - Clean the Endface if Necessary
When the ber endface image is focused onscreen, it may be apparent that it needs to be
cleaned. Follow these instructions to clean the ber endface.

Page 13
M-UM010-02 TTK 720 06/18
The software will run an automated analysis of the endface image and provide a PASS or FAIL
designation. If you want to try cleaning again, or if the image does not need to be saved, press the
“Back” button onscreen or the button on the VIS 300C probe to return to a live image.
3d - Run Automated Analysis
When the ber has been cleaned to the best of your ability (using dry and wet/dry methods),
the image may be analyzed.
Touch “Analyze” onscreen,
OR

Also known as “insertion loss” or “ber sweep” testing, dB loss testing allows the technician to validate
that all ber pairs are in working condition. Saving of dB loss test results may be required for closeout
packages. This section explains the necessary steps for testing ber.

4a - Connect Test Jumpers for Referencing
The equipment must be referenced before testing begins. Plug the AC 523 into the DLS 355
and VIS 300C OPM port. Connect the paired LC end of the AC 523 jumper into the AC 4500
loopback as shown below. Turn the DLS 355 on and choose an appropriate wavelength. For SM
ber testing, 1310 and 1550 wavelengths are most common. Consult your build documentation
to determine which wavelength to use. This guide will show the use of the 1550 wavelength.

Page 16
M-UM010-02 TTK 720 06/18
4b - Set Reference in VIS 300C Software
When the test jumpers and loopback have been connected correctly, a reference must be set
before testing can begin.
Touch “Power Meter”
onscreen
-5.95dBm λ 1550nm
0.00dB λ 1550nm
The Power Meter screen interface will appear. All power meter testing (dB loss testing) will be done
from this screen.
IMPORTANT:
Ensure DLS 355 is turned on. Press the
“λ Wavelength” button to choose the
wavelength onscreen. This must match
the wavelength light on the DLS 355.
If the dBm value onscreen is between
-3dBm and -8dBm, press the “SetRef”
button onscreen. The reading will
immediately change to 0.00dB. This is
the mode you will use to test.

Page 17

4c - Set PASS/FAIL Parameters
Use the Settings menu to set PASS/FAIL parameters.
0.00dB λ 1550nm
Touch “Settings”
Touch each dark rectangle to set a MIN and MAX for testing. MIN should be set to zero. MAX
allowable loss varies by build. Check your build documentation if you are not sure what to set for a
MAX loss. The most common MAX loss setting is 3dB. Touch OK when nished.
Any readings which fall between the MIN and MAX will be displayed in GREEN. Any readings which
are below the MIN or above the MAX will be displayed in RED. This is eectively a PASS/FAIL test.
0.50dB λ 1550nm 5.98dB λ 1550nm

Page 18
M-UM010-02 TTK 720 06/18
4d - Set Up Insertion Loss Test
Once the reference has been set with the test instruments, the loopback module AC 4500 will
be inserted onto the ber pair at the tower top, and the AC 523 will be plugged onto the same
ber pair at the tower bottom. See diagram below.
NOTE:
Wireless carrier preferences vary on how these tests should be conducted. The diagram above
represents the most common (and most basic) test scenario. Always conduct carrier build guidelines if
unsure of the necessary procedures.
Contact ODM if you encounter test scenarios or connector types that are unfamiliar. We have many
accessory kits to match the requirements of major wireless carrier ber architectures.

4e - Save Insertion Loss Readings
When the test jumper and loopback are connected to the trunk ber pairs, a live insertion loss
value will be shown on the power meter screen. This number represents how much light is lost
between the DLS 355 and VIS 300C OPM (up one side of the pair, through the loopback, and
back down the other side of the pair.)
