Accessing the Users Manual
This guide provides basic information to help you get started
using the MultiFiber™Pro meter and source. For additional
information, see the MultiFiber Pro Users Manual on the Fluke
Networks website.
Safety
Warning
To prevent possible eye damage caused by hazardous
radiation, do not look directly into optical connectors
(see page 2). Some sources produce invisible radiation
that can permanently damage your eyes.
Caution
To prevent damage to fiber connectors, to prevent
data loss, and to ensure maximum accuracy of test
results, use proper cleaning procedures to clean all
fiber connectors before every use. Cover all connectors
with protective caps when not in use.
Read the additional safety information in the
MultiFiber Pro Users Manual before you use the meter
or source.

Polarity Detection
Polarity Detection
You can use the MultiFiber Pro meter and source to see the
polarity of MTP/MPO patch cords and cables. The signals from
the source include the channel numbers. The meter compares
the transmitted numbers to the numbers of the channels that
received the signals. The meter can then show the polarity of
the connections. See item
 on page 5.
Auto Wavelength Function
The signal from the source includes an identifier that tells the
meter which wavelength to measure. The source transmits the
auto wavelength signal unless it is in 2kHzmode. When you
select 2kHzmode, the source’s AUTO setting automatically
changes to OFF.
How to Clean MTP/MPO Connectors
Always clean and inspect endfaces in fiber connectors before
you make connections. Fluke Networks recommends that you
use a mechanical cleaner, such as the Fluke Networks IBC™
OneClick Cleaner, to clean connectors.

How to Measure Optical Power
A power measurement shows the optical power level from a
source such as an optical network interface card or optical test
equipment.
To measure power
1 Clean and inspect all connectors.
2 On the meter, press to make POWER show.
3 Make the connections shown on page 11.
4 On the meter, press to select the wavelength of the
source if necessary.
5 To see the power measurement for the next channel, press
CHANNEL.
The bargraphs show the difference (in dB) between the
level of power on each channel and the maximum power
of all 12 channels:
At regular intervals, the meter finds the maximum power
level again and adjusts the bargraphs as necessary.
6 To save the measurements, make sure the meter has done
a scan through all 12 channels, then press SAVE. The
meter briefly shows the record number and OK. The
record number shown is for fiber number 12 in the cable.

How to Measure Loss
The loss measurement shows how much optical power is lost in
a link’s fiber and connectors.
Set the Reference
For the most accurate test results, you should set the reference
at these times:
 At the beginning of each day.
 Anytime you reconnect a test cord to the source.
 Anytime you see a negative loss measurement.

To set the reference
Caution
For correct measurements, connect only APC
connectors to the singlemode sources. Connect only
non-APC connectors to the multimode source.
For singlemode links with APC connectors, you must
use Type A test cords and adapters. Type A
components correctly align the angles in the
connectors.
1 Clean the connectors on the meter, source, and a test cord.
2 Turn on the meter and source and let them warm up for 10
minutes. Allow more time if the equipment has been stored
above or below ambient temperature.
3 Make connections to set the reference. The figure on page
13 shows reference connections for links with unpinned
connectors. The Users Manual shows connections for links
with other types of connectors and for fiber modules.
4 On the source, hold down for 2.5 seconds to see the
setup menu, then select these settings:
 SCAN ALL: ON
 MODE: 2 kHz does not show
5 On the meter, press to make SET REF show.
6 If necessary, press CHANNEL to see the power
measurement for each channel.
7 To save the reference measurements, press SAVE. The
meter saves the measurements and the display briefly
shows , OK and REF. Then the meter goes into loss
measurement mode.

13
How to Measure Loss
If the display shows and , the power level is too
low on one or more channels. This can be caused by a
bad connection or incorrect settings on the source. See
the Users Manual.
Caution
Do not disconnect test cord 1 from the source after
you set the reference.

Set the Limit
The meter compares loss measurements to a limit to give a
status of OK or to the measurements. If a measurement for a
channel exceeds the limit, flashes, the bargraph for that
channel flashes, and the bargraph shows an oval above the limit
line on the display.
To set the limit

3 Clean and inspect the connectors on the link and on the
required test cords.
4 Disconnect the test cord from the meter, then make the
appropriate connections. The figure on page 15 shows
connections for a link with unpinned connectors. The Users
Manual shows connections for other types of links and
connectors and for fiber modules.
Caution
Do not disconnect test cord 1 from the source. If you
do, you must set the reference again to make sure the
loss measurements are reliable.
For singlemode links with APC connectors, you must
use Type A test cords and adapters. Type A
components correctly align the angles in the
connectors.

6 On the meter, press to make LOSS show.
The bargraphs show the level of power loss relative to the
limit you set:
 When all ovals are below the line for a channel, the
measurement for that channel is below the limit you set.
 If the loss for a channel exceeds the limit, the oval above
the line is on, and and the bargraph for that channel
flashes.
 If the loss is negative by more than -0.09 dB, and the
