WSafety Information
Warning
To avoid possible eye damage caused by
hazardous radiation:
•Never look directly into optical output
connectors. Some sources produce in-
visible radiation that can permanently
damage your eyes.
•Do not open the case, except to change
the battery; no user-serviceable parts are
inside.
Caution
To avoid false test results, replace the bat-
tery as soon as the low battery indicator
(BAT) appears.
Cleaning Fiber Connections
Always clean the fiber ends before making connections.
Use any of the following:
•Lint-free swabs or wipes moistened with isopropyl
alcohol
•Pre-moistened swabs or wipes approved for use on
fiber connectors
Canned air approved for use on fiber connectors is also
useful for dislodging contamination. Protect all connectors
with dust caps when not in use.

Optical Fiber Test Kit
Introduction
The FTK100 Optical Fiber Test Kit is used to measure
optical power and optical power loss at 850 nm, 1300 nm,
1310 nm, and 1550 nm. The FM130 Fiber Meter (also
referred to as “the meter”) includes the following features:
•Measures optical power loss of multimode or
singlemode fibers.
•Measures output power from optical sources such as
network interface cards and optical test equipment.
•Displays output power measurements in dBm or µW.
•Operates for up to 50 hours on a single 9 V battery.
Automatic power-down feature helps conserve
battery power.
•Displays remaining battery life.
•Designed to use the optional ToolPakMeter
Hanging Kit from Fluke.
The FTK100 Kit includes a Fluke FOS-850/1300 Fiber
Optic Source, which provides light for multimode testing
at 850 nm and 1300 nm. For testing singlemode fiber,
Fluke offers the optional LS-1310/1550 Laser Source.
The instructions in this guide assume you are using the
FOS-850/1300 source included. For other optical
sources, refer to the manufacturer’s instructions.

Measuring Optical Power
Optical power is the output power produced by a source
such as an optical network interface card or optical test
equipment. You can measure power at a source or at the
end of a fiber link.
To measure optical power, proceed as follows:
1. Verify that the meter and source are set to the proper
wavelength. Let the source warm up for two minutes,
if necessary.
2. Clean all fiber ends.
3. Make the connections shown in Figure 5.
4. Verify that the meter is in the power measurement
mode. The measurement unit should be dBm. If
necessary, press Dto change the measurement unit
to dBm. To change the unit to µW, hold down Duntil
HELD appears.
5. Read the power measurement.

Setting a Reference for Loss
Measurements
Setting a reference lets the meter automatically subtract
from loss measurements the losses due to patch cords.
The loss for a fiber under test is automatically calculated
as the difference between the reference loss and the loss
with the fiber inserted.
For the most accurate test results, you should set the
reference at these times:
•Anytime you start using a different optical source for
loss measurements.
•Anytime you change the patch cord used on the
meter or source.
Note
For the most accurate test results, set the
reference at the beginning of each day using the
patch cords and wavelength settings you will use
for testing.
The meter stores a separate reference value for each
wavelength. The reference values are not affected when
you turn the meter off or change the battery.
To view the reference for the selected wavelength, press
rbriefly.
To set a reference, proceed as follows:
1. Set the source to the wavelength you will use for
testing. Let the source warm up for two minutes.
2. Select two known-good patch cords of the same type
as the fiber to be tested. Select one known-good
adapter of the appropriate type. Clean all fiber ends.
3. Make the connections shown in Figure 6. Turn on the
meter. Press Nto select the proper wavelength.
Normally, the reading will be about -20 dBm. If the
reading is too low, check the source connections and
wavelength, or clean the fiber ends again, or select
different patch cords, or use a different adapter.
4. To set the reference, hold down runtil HELD
appears on the display. The loss reading should then
change to 0 dB. The last digit may vary slightly
because of fiber movement and minor variations in
the output power of the source.
5. If you are testing with more than one wavelength,
change the meter and source to the new wavelength,
then repeat step 4.

Measuring Optical Power Loss
Optical power loss is the light energy lost through the
fiber, adapters, splices, and other components in a fiber
link. The loss for a fiber under test is automatically
calculated as the difference between the loss with the
fiber inserted and the reference loss. (See Figures 6
and 7.)
To measure loss, proceed as follows:
1. Verify that the meter and source are set to the proper
wavelength. Let the source warm up for two minutes,
if necessary.
Note
The patch cords used for loss measurements
should be the same patch cords used to set the
reference at the wavelength you are testing. If
the patch cords have been disconnected from
the meter or source since the reference was set,
set the reference again before measuring loss.
2. Clean all fiber ends.
3. Set a reference, if necessary. (See the previous
section “Setting a Reference for Loss
Measurements”for details.)
4. Make the connections shown in Figure 7.
Note
The additional test jumper used during loss
measurement ensures that the loss you measure
includes the fiber to be tested and the
connections at both ends of the fiber.
5. Verify that the meter is in the loss measurement
mode. If so, the unit of measurement will be dB. If it
is not, press D.
6. Read the loss measurement.

Maintenance
Clean the case with a soft cloth dampened with water or a
mild detergent. Do not use solvents or abrasive
cleansers.
Always cover the connector with the dust cap when not
using the meter.
Do not open the case (except to replace the battery). No
user-serviceable parts are inside.
Battery Replacement
Replace the battery in the FM130 Fiber Meter when BAT
appears at the top of the display. Refer to Figure 8.
Replace the battery in the FOS-850/1300 Fiber Optic
Source when LED blinks or does not turn on. Refer to
