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 meter 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.
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.
~Do not put products that contain circuit boards into waste
containers. Refer to local regulations for disposal procedures.

Safety Information
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 meter. An APC
connector will cause damage to the fiber endface in
the connector on the meter. See Figure 3.
• Use only patch cords that comply with GR-326-CORE
specifications. 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 meter to a network that is on. If
you do, the meter can cause problems in the network.
• If ACTIVE LINE blinks, immediately disconnect the
meter from the fiber. Optical power levels more than
+7 dBm can cause damage to the detector in the
meter.

APC/UPC
Angled Physical Contact/Ultra Physical Contact. If most cables
you will do tests on have UPC connectors, set this to UPC.
BACKLIGHT
The display backlight turns off if you do not press a key for the
period of time shown. You can set the time to 5 to 60 seconds in
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 meter 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
Select feet or meters as the unit for length measurements.
dB LIMIT
Sets the minimum size of a reflection that the meter shows as a
break or the end of the fiber when the reflection is before the
end of the fiber. You can select -35 dB (larger reflection), -40 dB,
or -45 dB (smaller reflection). The default is -40 dB.

The Connector Adapter
The Connector Adapter
The meter has an SC connector adapter that you can remove to
clean the fiber endface in the port (Figure 5).
How to Clean Connectors and Adapters
Always clean and do an inspection on fiber connectors before
you make connections. Use fiber optic solvent and optical-grade
wipers or swabs to clean connectors. You can purchase these
supplies from Fluke Networks.
How to Clean the Connector on the Meter
1 Turn off the meter.
2 Remove the connector adapter to get access to the ferrule
(see Figure 5).
3 Touch the tip of an optical-grade solvent pen or swab
soaked in solvent to a dry, optical-grade wiper.
4 Touch a new, dry swab to the solvent on the wiper.
5 Twist the swab around against the fiber endface 3 to 5
times, then twist a dry swab around against the fiber
endface 3 to 5 times.

How to Clean Connectors and Adapters
How to Clean Bulkhead Connectors (sources and
patch panels)
1 Do steps 2 and 3 above to put solvent on a swab.
2 Push the swab into the connector, twist it around 3 to 5
times against the endface, then discard the swab.
3 Twist a dry swab around in the connector 3 to 5 times.
4 Before you make a connection, use a fiber microscope (for
example, the Fluke Networks FiberInspector™Video
Microscope) to do an inspection on the connector.
How 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).
Always put protective caps on connectors you do not use. At
intervals, clean the caps with a swab or wipers and fiber optic
solvent.

How to Use the Meter
Notes
Always use patch cords that comply with GR-326-CORE
specifications. Other patch cords can cause unreliable
measurements.
Do not use the meter to measure fibers that have PC
connectors. PC connectors cause large reflections that
the meter shows as the end of the fiber.
1 Clean all fiber connectors.
2 Connect the fiber to the meter, as shown in Figure 6.
To connect to APC connectors, use a UPC/APC patch cord. To
connect to UPC connectors, use a UPC/UPC patch cord.
3 Turn on the meter, then press T.
Note
After you turn on the meter, it shows for a short
time to show that it operates correctly.
WCaution
If ACTIVE LINE blinks, immediately disconnect the
meter from the fiber. Optical power levels more than
+7 dBm can cause damage to the detector in the
meter.

Measurement Results
The meter measures the length of the fiber. The length can be
the distance to an APC or UPC connector at the end of the fiber
or the distance to a break. If there is a large reflective event
before the end of the fiber (larger than the dB LIMIT setting) the
meter shows the distance to that event.
The meter can show these results in the given situations:
The meter shows 0m, 0ft, 1m, or 1ft.
• The connection to the meter is bad.
• The connector on the meter or the fiber is dirty. See page 11
for instructions on how to clean the connectors.
• The meter is connected to a PC connector. PC connectors
cause large reflections that the meter shows as the end of
the fiber.
The meter shows J6000 m or J9999 ft.
The fiber is longer than the meter can measure.
The meter shows Iwith the measurement.
APC connectors make very small reflections. On some short
fibers, this small reflection is hidden in the reflection from the
bulkhead connector on the meter. In these situations, the meter
shows a range (for example, < 9 m), rather than an exact length.
The length measurement is incorrect.
• The I.O.R. (index of refraction) is incorrect. See page 8.
• The cable has PC connectors. PC connectors cause large
reflections that the meter shows as the end of the fiber.

Maintenance
Maintenance
To clean the display, use lens cleaner and a soft, lint-free cloth.
To clean the case, use a soft cloth that is moist with water or
water and a weak soap.
WCaution
To prevent damage to the display or the case, do not
use solvents or abrasive materials.
To clean the optical connector, use the procedure given on page
11.
WWarningX*
To prevent possible fire, electrical shock, personal
injury, or damage to the meter:
• Do not open the case. You cannot repair or replace
parts in the case.
• Use only replacement parts that are approved by Fluke
Networks.
• If you replace parts that are not specified as
replacement parts, the warranty will not apply to the
product and you can make the product dangerous to
use.
• Use only service centers that are approved by Fluke
Networks.
Note
If the meter shows ERROR2, servicing is necessary.
Speak to a Fluke Networks representative. See page
