Essentials for Reliable Fiber Test Results
To get reliable fiber test results, you must follow proper
cleaning and referencing procedures and, in some cases,
use mandrels during testing.
Cleaning Connectors and Adapters
Always clean and inspect fiber connectors before making
connections. Use fiber optic solvent and optical-grade
wipes or swabs to clean connectors as follows:
Bulkhead Connectors and the Fiber Module's Output Connector
Note
Use a 2.5 mm foam swab for cleaning the fiber
module's output connector.
1
Touch the tip of a fiber optic solvent pen or swab
soaked in solvent to a lint-free dry wipe or fiber
cleaning card.
2
Touch a new, dry swab to the solvent spot on the wipe
or card.
3
Push the swab into the connector; twist it around 3 to
5 times against the endface, then remove and dispose
of the swab.
4
Dry the connector with a dry swab by twisting it
around in the connector 3 to 5 times.
5
Inspect connectors with a fiber microscope, such as the
Fluke Networks FiberInspector Video Microscope
before making connections.
Fiber Module's Input Connector
1
Remove the connector adapter to expose the
photodiode lens (see Figure 6).
2
Use the method described in steps 1 and 2 above to
dampen a swab with solvent.
3
Twist the damp swab around against the lens 3 to 5
times; then twist a dry swab around against the lens 3
to 5 times.
Connector Adapters and Fiber Adapters
Periodically clean connector adapters and fiber adapters
with a swab and fiber optic solvent. Dry with a dry swab
before use.
16
Essentials for Reliable Fiber Test Results
Connector Ends
1
Touch the tip of a fiber optic solvent pen or swab
soaked in solvent to a lint-free dry wipe or fiber
cleaning card.
2
Wipe the connector end-face across the solvent spot,
then back and forth once across the dry area of the
wipe or card.
Note
Some connector styles, such as VF-45, may require
a different cleaning method.
3
Inspect connectors with a fiber microscope, such as the
Fluke Networks FiberInspector Video Microscope
before making connections.
Always cover unused connectors with protective caps. Clean
caps periodically with a swab or wipe and fiber optic
solvent.
About Setting the Reference
The reference serves as the baseline power level for loss
measurements. Regular referencing helps account for
minor variations in source power and connection integrity.
Also, since the reference is the baseline for measurements,
the losses of the test reference cords and adapters used
during referencing are excluded from test results.
Note
Turn on the tester and smart remote and let them
sit for 5 minutes before setting the reference.
Allow additional time if the modules have been
stored above or below ambient temperature.
You should set the reference at these times:
•
At the beginning of each day using the remote end

WCaution
Do not disconnect the test reference cords from
the testers' output ports after setting the
reference. Doing so may alter the amount of
optical power launched into the fiber and
invalidate the reference.
Reference values should not change by more than a few
tenths of a dB from day to day. Larger changes may
indicate a problem with the test reference cords or
connections.
See the sections on Smart Remote, Loopback, and Far End
Source modes for details on setting the reference for each
mode.
Selecting Test Reference Cords
The DTX Fiber Modules come with high-quality test
reference cords.
To ensure that your measurements are accurate and
repeatable, use test reference cords provided by Fluke
Networks or cords of the same quality. See "Replacing
Fiber Test Reference Cords" on page 61.
Testing Your Test Reference Cords
You must test your test reference cords at regular intervals.
Use the procedure given in Appendix A to test the cords
initially. After that, use the procedure given with the
procedures for certifying cabling to monitor the condition
of the cords.
Using Mandrels for Testing Multimode Fiber
You should use mandrels when testing multimode fiber
with the DTX-MFM2 fiber modules. Mandrels can improve
measurement repeatability and consistency. They also
allow the use of LED light sources to certify 50 µm and
62.5 µm fiber links for current and planned high bit-rate
applications, such as Gigabit Ethernet and 10 Gigabit
Ethernet.
WCaution
Do not use mandrels when testing with the
DTX-GFM2 fiber modules.
18
Essentials for Reliable Fiber Test Results
The red mandrels included with the DTX-MFM2 are
compliant with ANSI/TIA-568-C for 50 µm fiber with a
3 mm jacket. Mandrels for 62.5 µm fiber are available from
Fluke Networks. Refer to the appropriate standard for
mandrel requirements if you follow other standards. Table
2 shows a partial list of mandrel requirements for TIA
standards.

When enabled in Smart Remote or Loopback mode, the tester prompts you to swap the test
connections halfway through the test. The tester can then make bi-directional measurements
for each fiber at each wavelength (850 nm/1300 nm, 850 nm/1310 nm, or 1310 nm/1550 nm).
If the selected limit uses a calculated loss limit, enter the number of adapters and splices that
will be added to the fiber path after the reference is set. Figure 11 shows an example of how to
determine the Number of Adapters setting.
Only limits that use maximum values for loss per km, loss per connector, and loss per splice use a
calculated limit for overall loss. For example, limits for fiber backbones use a calculated loss
limit.
Select the type of connector used in the cabling. This setting affects only the diagrams shown
for reference connections. If the cabling's connector type is not listed, use General.

The tester uses the index of refraction (n) defined in the currently selected fiber type (Default)
or a value you define (User Defined). The default value defined by the selected fiber type
represents the typical value for that fiber type. You may enter a different value if necessary. To
determine the actual value, change the index of refraction until the measured length matches
the known length of a fiber.
Increasing the index of refraction decreases the reported length.
Setting a reference sets the baseline power level for loss measurements. See “About Setting
the Reference” on page 17.
After you set the reference, you can enter the lengths of the test reference cords used. The
lengths are saved with results to meet TIA reporting requirements for fiber test results.
See “Preparing to Save Tests” on page 27.

About 1 Jumper Connections
The reference and test connections shown in this manual
produce 1 Jumper results. 1 Jumper results include the loss
of the fiber plus the loss of the connections at both ends of
the link. To ensure accurate results, the connection to the
fiber module's output port must not be disconnected after
the reference is set. Using connector adapters that match
the connectors in the fiber under test lets you connect to
the fiber without disturbing the output port connection.
WCaution
If you disconnect the test reference cords from
the tester’s or smart remote’s output port after
setting the reference, you must set the
reference again to ensure valid measurements.
If you do not have the correct connector adapters, see
Appendix C, "Modified 1 Jumper Method" for alternative
connections that produce 1 Jumper results.
To test links with different connectors at each end, see the
alternate method described in the Appendix of the DTX
Series CableAnalyzer Technical Reference Handbook or
visit the Fluke Networks Knowledge Base for suggestions.

Appendix A: How to Test Your Test Reference Cords
Why You Must Do this Test
To get accurate measurements of loss, you must use highquality test reference cords that are in good condition and
comply with ISO/IEC 14763-3. Measurements of optical
power loss are very much affected by the condition of the
endfaces on the fiber connectors. Dirty endfaces and
endfaces with damage are the most common causes of
problems in fiber links.
When You Must Do this Test
Test your test reference cords at these times:
•
At the start of each day
•
When you move your equipment to a different area
•
When you change your equipment to test links that
have a different type of connector
After you do the test given in this Appendix, use the
procedure given with the procedures for certifying cabling
to monitor the condition of the cords.
Equipment You Must Have
Figure A-1 shows the equipment you must have to test
your test reference cords.
WCaution
To do this procedure, you must have a fiber
microscope. You cannot be sure that your cords
are good unless you can examine the endfaces
on the connectors. An endface that is dirty or
has damage can give a good loss measurement,
but can cause problems later. See Figure A-2.

•
Fiber Type: Select the type of cable you will test. This
sets the index of refraction (n). The test limits shown
above use n to calculate the length of the fiber, then
they use the length to calculate the limit for loss.
Thus, you must use the correct value of n to get an
accurate measurement of loss. If you cannot find the
correct fiber type, you can enter the value of n for
your fiber on tab 3 of the setup menus. Get the
value of n from the cable vendor.

2. Clean and Inspect the Connectors
2-1
Test reference cords must have endfaces that are clean
and have no damage. Always use correct procedures to
clean endfaces. See page 16 or use the procedures
given with your cleaning supplies.

After you clean an endface, use a fiber microscope to
examine the endface. Figure A-2 shows examples of
what you can see with a fiber microscope.
AB
A
A clean endface that has no damage. This is the only
condition that you can accept for a test reference cord.

CD
C
Dirt is on the core. Also, there are scratches that were
caused by incorrect procedures for cleaning.
D

3. Set the Reference
3-1
Make the connections shown in Figure A-3.
3-2
Turn the rotary switch to SPECIAL FUNCTIONS, then
select Set Reference. If both a fiber module and a
twisted pair or coaxial adapter are attached, select
Fiber Module next.
3-3
Make sure that the reference value is good:
•
For 50/125 µm fiber, the reference value must be
better than -24.50 dBm (for example, -23.50 dBm is a
better value)
•
For 62.5/125 µm fiber, the reference value must be
better than -20.00 dBm (for example, -19.50 dBm is a
better value)
•
For 9/125 µm fiber, the reference value must be
better than -8.00 dBm (for example, -7.50 dBm is a
better value)
If the value is not good, do the reference procedure
again with a different test reference cord.

limits:
•
Multimode test reference cord: 0.10 dB or less
•
Singlemode test reference cord: 0.20 dB or less
If the connectors show no contamination or damage, but
the loss is higher than these limits, the cord does not
comply with ISO/IEC 14763-3. Do not use the cord as a test
reference cord.
