Safety Information
WWarning: Class 1 Laser*
To prevent possible damage to your eyes caused by
hazardous radiation:
• Do not look directly into optical connectors. Some
optical equipment emits invisible radiation that can
cause permanent damage to your eyes.
• Do not turn on the troubleshooter unless a fiber is
attached to the port.
• Do not use a magnifying device to look at the optical
outputs without the correct filter.
• Use of controls, adjustments, or procedures that are
not in this manual can cause exposure to hazardous
radiation.
WCaution
To prevent damage to fiber connectors, to prevent
data loss, and to make sure that your test results are
as accurate as possible:
• Do not connect APC connectors to the troubleshooter.
An APC connector will cause damage to the fiber
endface in the connector on the troubleshooter. See
Figure 3.
WWarning or Caution: Risk of damage to or destruction of
equipment or software. See explanations in the manual.
XWarning: Risk of electrical shock.
*Warning: Class 1 laser. Risk of damage to your eyes caused by
hazardous radiation.

Safety Information
• Connect only UPC connectors to the troubleshooter.
Use only patch cords that comply with GR-326-CORE
specifications and have UPC connectors. Other patch
cords can cause unreliable measurements.
• Use the correct procedures to clean all fiber connectors
before each test. If you do not do this or if you use
incorrect procedures, you can get unreliable test
results and can cause permanent damage to the
connectors.
• Put protective caps on all connectors when you do not
use them.
• Do not connect the troubleshooter to a network that
is on. If you do, the troubleshooter can cause problems
in the network.
• If ACTIVE LINE blinks, immediately disconnect the
troubleshooter from the fiber. Optical power levels
more than +7 dBm can cause damage to the detector
in the troubleshooter.
• The troubleshooter senses optical signals between
1310 nm and 1550 nm. If there might be signals at
other wavelengths on a fiber, use a different
instrument to make sure that the fiber is not active
before you connect the troubleshooter to the fiber.

increments of 5 seconds.
I.O.R. (index of refraction)
The index of refraction is the ratio of the speed of light in a
vacuum to the speed of light in a fiber. The troubleshooter uses
the index of refraction to calculate length. If you increase n, the
calculated length decreases. The default is 1.468. This value is
satisfactory for most fibers.
ft/m/kft/km
Select feet, meters, kilofeet, or kilometers as the unit for length
measurements. The default is feet.
LOSS LIMIT
Sets the minimum level at which the troubleshooter shows the
warning LOSS LIMITWfor an incident. For example, if you select
a limit of 2.0 dB, the troubleshooter shows the warning for
incidents above 2.0 dB. You can select a value from 0.5 dB (lower
loss) to 6.1 dB (higher loss) in 0.1 dB increments. The default is
0.5 dB.

The Connector Adapter
REFLECTION LIMIT
Sets the minimum size at which the troubleshooter shows the
warning REFLECTION LIMITWfor an incident. For example, if
you select a limit of -35 dB, the troubleshooter shows the
warning for incidents above -35 dB. You can select a value from
-24 dB (larger reflection) to -62 dB (smaller reflection) in 1 dB
increments. The default is -45 dB.
The Connector Adapter

How to Clean Connectors
Fluke Networks recommends that you use a mechanical device
to clean connectors. If you do not have such a device, use other
optical-grade supplies to clean connectors.
How to Use a Mechanical Device
WCaution
To prevent damage to the device and to connectors,
read all instructions and obey all safety precautions
given by the manufacturer of the device you use to
clean connectors.
1 To clean a bulkhead connector, remove the cap. To clean
the connector on a fiber cable, remove only the tip of the
cap.
2 If necessary for a bulkhead connector, extend the tip of the
device.
3 Push the device straight into the connector until you hear a
loud click. See Figure 6. Then remove the device.

How to Clean Connectors
How to Use Swabs, Wipers, and Solvent
To clean bulkhead connectors:
1 Touch the tip of an optical-grade solvent pen or swab
soaked in solvent to a dry, optical-grade wiper.
2 Touch a new, dry swab to the solvent on the wiper.
3 Push the swab into the connector, twist it around 3 to 5
times against the endface, then discard the swab.
4 Twist a dry swab around in the connector 3 to 5 times.
To clean connector ends:
1 Touch the tip of an optical-grade solvent pen or swab
soaked in solvent to a dry, optical-grade wiper.
2 Rub the connector endface across the solvent on the wiper,
then rub it two times across the dry area of the wiper.
Note
A different procedure is necessary to clean some
connector styles (for example, VF-45).
Before you make a connection, use a fiber microscope (for
example, the Fluke Networks FIBERINSPECTOR™Video Microscope)
to do an inspection on the connector.
Always put protective caps on connectors that you do not use.
At intervals, clean the caps with a swab or wipers and fiber optic
solvent.

About Launch and Receive Fibers
Launch and receive fibers give the troubleshooter a better view
of the first and last connectors in the link. If you do not use a
launch fiber, the troubleshooter cannot detect the loss of the
first connector in the link. If you do not use a receive fiber, the
troubleshooter cannot detect the loss of the last connector in
the link. Also, the reflectance measurement for the first and last
connectors will be inaccurate.
Usually, you do not need to use a launch or receive fiber with
the FIBER ONESHOT PRO tester. But you must use them in these
situations:
• You must use a launch fiber if you want to detect a loss
incident (such as a connector, splice, or macrobend) in the
first 30 m of the fiber link.
• You must use a receive fiber if you want to detect the loss
of the last connector in the fiber link.
If you use a launch or receive fiber, it must have a minimum
length of 30 m (98 ft).
When you use launch or receive fibers, be sure to subtract their
lengths from the length measurement to get the actual length
of the fiber you are testing.

How to Use the Troubleshooter
How to Use the Troubleshooter
Notes
Always use patch cords that comply with GR-326-CORE
specifications and have a UPC connector at the end you
will connect to the troubleshooter. Other patch cords
can cause unreliable measurements and damage to the
troubleshooter.
Do not use the troubleshooter to do tests on fibers
that have PC connectors. PC connectors cause large
reflections that the troubleshooter shows as the end of
the fiber.
1 Clean all fiber connectors.
2 Connect the fiber to the troubleshooter, as shown in
Figure 7.
3 Turn on the troubleshooter, then press T. The
troubleshooter automatically saves the results.
Note
After you turn on the troubleshooter, it shows
for a short time to show that it operates correctly.
WCaution
If ACTIVE LINE blinks, immediately disconnect the
troubleshooter from the fiber. Optical power levels
more than +7 dBm can cause damage to the detector
in the troubleshooter.
