LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke Networks product is warranted to be free from defects in material and workmanship under normal use and service unless
stated otherwise herein. The warranty period for the mainframe is one year and begins on the date of purchase. Parts, accessories,
product repairs and services are warranted for 90 days, unless otherwise stated. Ni-Cad, Ni-MH and Li-Ion batteries, cables or other
peripherals are all considered parts or accessories. The warranty extends only to the original buyer or end user customer of a Fluke
Networks authorized reseller, and does not apply to any product which, in Fluke Networks’ opinion, has been misused, abused, altered,
neglected, contaminated, or damaged by accident or abnormal conditions of operation or handling. Fluke Networks warrants that
software will operate substantially in accordance with its functional specifications for 90 days and that it has been properly recorded on
non-defective media. Fluke Networks does not warrant that software will be error free or operate without interruption.
Fluke Networks authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no
authority to extend a greater or different warranty on behalf of Fluke Networks. Warranty support is available only if product is
purchased through a Fluke Networks authorized sales outlet or Buyer has paid the applicable international price. To the extent
permitted by law, Fluke Networks reserves the right to invoice Buyer for repair/replacement when a product purchased in one country
is submitted for repair in another country.
Fluke Networks warranty obligation is limited, at Fluke Networks option, to refund of the purchase price, free of charge repair, or
replacement of a defective product which is returned to a Fluke Networks authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke Networks authorized service center to obtain return authorization information,
then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB destination). Fluke
Networks assumes no risk for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation
prepaid (FOB destination). If Fluke Networks determines that failure was caused by neglect, misuse, contamination, alteration, accident
or abnormal condition of operation or handling, or normal wear and tear of mechanical components, Fluke Networks will provide an
estimate of repair costs and obtain authorization before commencing the work. Following repair, the product will be returned to the
Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping point).
THIS WARRANTY IS BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE
NETWORKS SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING
LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or
consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty
is held invalid or unenforceable by a court or other decision-maker of competent jurisdiction, such holding will not affect the validity or
enforceability of any other provision.

MultiFiber™ Pro Fiber Test Kits
Introduction
The MultiFiber™Pro meter and source let you measure
optical power and power loss in fiber installations that have
MTP®/MPO connectors.
In one test, the meter measures optical power or power loss
on 12 fibers at one wavelength. The test results include the
polarity of the connections (A, B, C, or other). The meter
measures at 850 nm, 1300 nm, 1310 nm, or 1550 nm.
MultiFiber Pro sources supply optical power at 850 nm,
1310 nm, or 1550 nm.
The meter stores the loss or power measurements for up to
250 12-fiber cables. You can use LinkWare™PC software to
upload the records to a PC and create professional-quality
test reports. You can download LinkWare PC from the Fluke
Networks website.

 Carefully read all instructions.
 Do not open the case. You cannot repair or replace
parts in the case.
 Do not modify the Product.
 Use only replacement parts that are approved by
Fluke Networks.
 Do not use the Product around explosive gas,
vapor, or in damp or wet environments.
 Use this Product indoors only.
 Use the Product only as specified, or the protection
supplied by the Product can be compromised.
 Do not use and disable the Product if it is damaged.
 Do not use the Product if it operates incorrectly.
 Batteries contain hazardous chemicals that can
cause burns or explode. If exposure to chemicals
occurs, clean with water and get medical aid.
 Remove the batteries if the Product is not used for
an extended period of time, or if stored in
temperatures above 50 °C. If the batteries are not
removed, battery leakage can damage the Product.
 The battery door must be closed and locked before
you operate the Product.
 Repair the Product before use if the battery leaks.
 Replace the batteries when the low battery
indicator shows to prevent incorrect
measurements.
 Be sure that the battery polarity is correct to
prevent battery leakage.
 Do not disassemble or crush battery cells and
battery packs.
 Do not put battery cells and battery packs near
heat or fire. Do not put in sunlight.
 Have an approved technician repair the Product.
Warning: Class 1 Laser
To prevent possible eye damage caused by
hazardous radiation:
 Do not look directly into optical connectors (see
Figure 2). Some optical equipment emits invisible
radiation that can cause permanent damage to
your eyes.
 Do not turn on the source unless a fiber is attached
to the port.
 When you inspect fiber endfaces, use only
magnification devices that have the correct filters.
 Use of controls, adjustments, or procedures not
stated herein can possibly result in hazardous
radiation exposure.

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. Neglecting this step
or using improper procedures can cause unreliable
test results and may permanently damage the
connectors.
 Cover all connectors with protective caps when not
in use.
 For correct measurements, connect only APC
connectors to the singlemode sources. Connect
only non-APC connectors to the multimode source.
You can connect APC or non-APC connectors to the
meter.
 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.
 Do not connect the source to an active network.
Doing so can disrupt network operations.
 After you turn on the source, let it warm up for 10
minutes before use. Allow additional time if the
source has been stored above or below ambient
temperature.

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:
 A, B, C: The connections use a standard method, A, B,
or C. See Figure A-1 on page 38.
 POLARITY ?: The connections do not use a standard
method, one or more fibers are not connected, or
SCAN ALL is off on the source.
 UNIV: Shows when modules have the Corning Plug &
Play™Universal Systems method of polarity
management. See Figure B-16 on page 57.
2 kHz Mode
The source has a 2 kHz modulated output mode that you
can use to identify fibers. See"How to Identify Cables or
