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.
 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.

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 Use a video microscope, such as the Fluke Networks FI-7000
FiberInspector™Pro, to inspect the connector. If it is dirty,
continue to step 2.
Key
Slot
Keep extra adapters in
the containers provided.

How to Clean Connectors
2 To clean a bulkhead connector, remove the device’s cap. To
clean the connector on a fiber cable, remove only the tip of
the cap.
3 If necessary for a bulkhead connector, extend the tip of the
device.
4 Push the device straight into the connector until you hear a
loud click. See Figure 6. Then remove the device.
5 Use a video microscope to inspect the connector. If
necessary, clean and inspect the connector again.
If the mechanical device does not clean the connector
sufficiently, use a swab and solvent to clean the connector.
ghm09.eps
Figure 6. How to Use a Mechanical Device

FIBER ONESHOT PRO Users Manual
4 Push the swab into the connector, twist it around 3 to 5
times against the endface, then discard the swab.
5 Twist a dry swab around in the connector 3 to 5 times.
6 Use a video microscope to inspect the connector. If
necessary, clean and inspect the connector again.
To clean connector ends:
1 Use a video microscope to inspect the connector. If it is dirty,
continue to step 2.
2 Touch the tip of an optical-grade solvent pen or swab
soaked in solvent to a dry, optical-grade wiper.
3 Rub the connector endface across the solvent on the wiper,
then rub it two times across the dry area of the wiper.
4 Use a video microscope to inspect the connector. If
necessary, clean and inspect the connector again.
Note
A different procedure is necessary to clean some
connector styles (for example, VF-45).
Protect Connectors
Always put protective caps on connectors that you do not use.
Clean the caps periodically with a swab or wipers and fiber optic
solvent.

About Launch and Receive Fibers
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
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 . 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.

How to Do Tests Through Attenuators
The troubleshooter gives accurate results through attenuators
that have 1 dB to 2 dB of attenuation.
Attenuators with more than 2 dB can possibly cause the
troubleshooter to miss events. To do tests on fibers that have
attenuators with more than 2 dB, connect directly to the fiber
after the attenuator. In general, you should not do tests through
attenuators.
Measurement Results
The troubleshooter measures the loss and reflectance of
incidents on the fiber and the distance to the incidents. Typically,
an incident is the end of the fiber, a connection, or a fault such
as a break or a bad splice. See Figures 8 and 9.
If there is a break or an open connection on the fiber, the
troubleshooter does not show incidents after the break.
 To see the results for other incidents, press . The
troubleshooter shows up to 9 incidents.
 To switch between measurements of reflectance and loss
for an incident, press .
