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. 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. Fluke Networks reserves the right to
invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted for repair in another

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.

OF-500 OptiFiber Certifying OTDR

Note

While this manual describes specific operating
procedures for the OptiFiber tester, the fiber
test methods described are provided only as
guidelines. Your test methods may vary.

Overview of Features

The OF-500 OptiFiber® Certifying OTDR (hereafter
referred to as the tester) is a hand-held Optical Time
Domain Reflectometer (OTDR) that locates and
characterizes reflective and loss events in multimode and
singlemode fibers. The tester is optimized for use on the
shorter fiber runs typically installed in premises (building
and campus) networks. Typical test ranges are up to 7 km
at 1300 nm for multimode fiber and up to 60 km for
singlemode fiber.

The tester offers the following features:

• Automated OTDR trace and event analysis help you

identify and locate faults on multimode (850 nm and
1300 nm; 50 µm and 62.5 µm) and singlemode
(1310 nm and 1550 nm; 9 µm) fiber.

• Displays OTDR results in summary format, as a table

of events, or as an interpretive OTDR trace.
PASS/FAIL results are based on factory-installed limits
or limits you specify.

Safety Information

Table 1 shows the international electrical symbols used
on the tester or in this manual.

Table 1. International Electrical Symbols

X
W

*

Warning: Risk of fire, electric shock, or personal
injury.

Warning or Caution: Risk of damage or
destruction to equipment or software. See
explanations in the manuals.

Warning: Class 1 laser (OUTPUT port). Risk of eye
damage from hazardous radiation.

Do not put products containing circuit boards

~

into the garbage. Dispose of circuit boards in
accordance with local regulations.

To avoid possible eye damage caused by
hazardous radiation and to avoid possible fire,
electric shock, or personal injury:

• Never look directly into optical connectors.

Some sources produce invisible radiation that
can permanently damage your eyes.

• Never run any tests that activate the tester’s

outputs unless a fiber is attached to the output.

• Do not open the case; no user-serviceable parts

are inside.

• Do not modify the tester.

• Do not use magnification to view the optical

outputs without proper filtering.

• Use of controls, adjustments, or procedures not

stated herein might result in hazardous
radiation exposure.

• Use only the ac adapter provided to charge the

battery or power the tester.

• Do not use the tester if it is damaged. Inspect

the tester before use.

Warning

9

OF-500 OptiFiber Certifying OTDR

Users Manual

• If this equipment is used in a manner not

specified by the manufacturer, the protection
provided by the equipment may be impaired.

WCaution

To avoid damaging the tester or cables under
test and to avoid data loss:

• Always turn the tester off before removing or

installing a module.

• Never connect the OTDR port to an optical

source. Doing so can damage the OTDR
receiver.

• Never connect the tester to an active network,

except when using the power meter. Doing so
causes unreliable test results and can disrupt
network operations.

• If the tester shows an error because the power

reading is too high, immediately disconnect the
source from the tester. The tester is not
designed for measuring higher power levels,
such as produced by CATV, optical amplifiers,
and cellular systems.

• Avoid touching reflective surfaces (such as

metal) to the end of a fiber cable plugged into
the OTDR when the OTDR is operating. An
open fiber connector end face has about a 4%
reflection. Holding a reflective surface near the
connector end face may cause much greater
than a 4% reflection, which may damage the
photodetector in the OTDR.

• 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.

• Use a Fluke Networks FiberInspector Video

Microscope to periodically inspect the OTDR
and loss/length option’s OUTPUT connectors for
scratches and other damage.

Safety Information

• Read the instructions for splice machines before

using the OTDR to monitor splicing procedures.
The OTDR can interfere with the light injection
detection techniques used by some splicers.

• To avoid unreliable test results, connect the ac

adapter or replace the battery as soon as the
low battery indication appears.

• You may use a PC to move or copy test record

(.tst) files from a memory card, but do not
rename the .tst files. Doing so may result in loss
of data.

• Never remove the memory card while the

memory card’s LED is on. Doing so can corrupt
the data on the card.

Cleaning and Inspecting Fiber Connectors and Adapters

Cleaning and Inspecting Fiber Connectors and Adapters

Always clean and inspect fiber connectors before making
connections. Use 99 %-pure isopropyl alcohol and
optical-grade wipes or swabs to clean fiber connectors as
follows:

WCaution

See pages 39 and 52 for instructions on cleaning
the tester's OTDR and loss/length connectors.

• Connector ends: Wipe the end of the ferrule with a

swab or wipe lightly moistened with alcohol. Dry
with a dry swab or wipe.

• Bulkhead adapters:

1 Touch the tip of a lint-free foam swab to an

alcohol-soaked cleaning pad.

2 Push the swab into the adapter; twist it around

3 to 5 times against the endface, then remove
and dispose of the swab.

3 Dry the endface with a dry, lint-free swab by

twisting it around in the adapter 3 to 5 times.

• Inspect connectors with a fiber microscope, such as

the Fluke Networks FiberInspector Video Probe
before making connections. See “Using the
FiberInspector Option” on page 46 for details.

• Periodically clean fiber adapters with a swab and

alcohol. Dry adapters with a dry swab before use.

• Always cover unused connectors with dust caps or

plugs. Clean dust plugs periodically with a swab or
wipe and alcohol.

Users Manual

Testing Your Reference Test Cords and Launch Fiber

You should test your reference test cords and launch
fiber before each job. Use another set of known-good
cords to set a reference and run an Autotest on each cord
and launch fiber. Use Smart Remote mode to test two
cords at a time, or Loopback mode to test one cord.

You should also use a fiber microscope, such as the
FiberInspector video probe, to inspect the reference test
cord and launch fiber connectors for damage at least
once a day.

Using the OTDR

The OTDR helps you identify and locate faults on fiber
cabling. It also measures length, event loss, and overall
loss of the cabling and provides PASS/FAIL results based
on a selected test limit.

About Launch and Receive Fibers

Launch and receive fibers let the tester measure the loss
and reflectance of the first and last connectors in the
cabling, and include those connectors in ORL (optical
return loss) measurements. Without launch and receive
fibers, no backscatter is available before the first
connector and after the last, so the tester cannot
measure the connectors’ characteristics.

If the first or last connection in the cabling is bad, and
you do not use launch and receive fibers, the OTDR test
may pass because it does include measurements from the
bad connection.

28

Using the OTDR

OVERALL LOSS and FIBER LENGTH include the loss and
length of the launch and receive fibers, unless you use
the launch/receive fiber compensation function. See the
online help or the Technical Reference Handbook for
details on launch fiber compensation.

Fluke Networks recommends that you use launch and
receive fibers. You should also use launch/receive fiber
compensation to remove the effects of these fibers from
the OTDR measurements.

Note

Avoid using hybrid patch cords to connect to the cabling
under test. Connect the launch and receive fibers directly
to the cabling under test, using a launch fiber with the
appropriate connectors. This provides the best view of
the connectors at the ends of the cabling. Hybrid launch
fibers with various connector styles are available from
Fluke Networks.

Selecting Auto or Manual OTDR Mode

Note

You should use Auto OTDR mode when
certifying cabling with the OTDR.

From the HOME screen, press
Auto OTDR or Manual OTDR from the popup menu.

In Auto OTDR mode, the tester automatically selects
settings based on the length and overall loss of the
cabling. This mode is the easiest to use, provides the most
comprehensive view of the events on the cabling, and is
the best choice for most applications.

Manual OTDR mode lets you change settings to optimize
the OTDR for displaying specific events. See the online
help or the Technical Reference Handbook for details.

OTDR Connection Quality

When you run an OTDR test, the tester determines the
quality of OTDR port connection (Figure 7).

If the gauge is in the Poor range, you should clean the
OTDR port and the fiber connector. Use a video
microscope, such as the FiberInspector video probe, to
inspect the port and fiber connector for scratches and
other damage. If a connector on the tester is damaged,
contact Fluke Networks for service information.

A poor OTDR connection increases the connector’s
deadzone, as shown in Figure 37 on page 94. The
deadzone can hide faults near the OTDR connector.

A poor connection also decreases the light available for
testing the fiber. The weakened test signal causes a
noisier trace, poor event detection, and decreased
dynamic range.

The port connection quality rating is saved with OTDR
result details.

Cleaning the INPUT Connector

Note

Typically, the input connector requires cleaning
only if it has been touched.

1 Remove the connector adapter to expose the

photodiode lens (see Figure 21).

2 Use the method described under "Cleaning the

Output Connector" above to dampen a swab with
alcohol.

3 Twist the damp swab around against the lens 3 to 5

times; then twist a dry swab around against the lens 3
to 5 times.

About Setting the Reference

Setting a reference lets the tester automatically subtract
out the losses due to reference test cords and the main
and remote tester.

Note

Always let your test equipment warm up for 5
minutes before setting a reference.

For the most accurate test results, you should set the
reference at these times:

• At the beginning of each day using the remote end

setup (Figures 25 through 32) you will use that day.
The tester reminds you to set the reference if the
reference is more than 12 hours old.

• Anytime you reconnect a reference test cord to the

tester or other source.

• Anytime the tester warns you that the reference is

out of date.

The tester requires you to set the reference at these
times:

• Anytime you change the loss/length module in the

main or remote tester.

• Anytime you start using a different remote tester.

• Thirty days after the reference was previously set.

The tester warns you if the reference value is outside of
an acceptable range.

To see the reference information for the current remote
end setup, select Set Loss/Length Reference from the
Functions menu; then press

See the sections "Testing in Smart Remote Mode",
"Testing in Loopback Mode", and "Testing in Far End
Source Mode" for details on setting the reference for
each mode.

Setting the Number of Adapters and Splices

The NUMBER OF ADAPTERS and NUMBER OF SPLICES
settings are on the Loss/Length tab in Setup. These
settings do not apply to all test limits.

Test limits that include maximum values for the loss per
km, loss per connector, and loss per splice use a
calculated limit for loss. Only limits with all three values
use a calculated loss limit. The OVERALL LOSS value
should be N/A in these limits. If a loss value is entered, it
is ignored.

To see the limit’s values, select TEST LIMIT on the
Loss/Length tab; then press

If the selected limit uses a calculated loss limit, enter the
number of adapters and splices that will be added to the
fiber path after the reference is set.

Using Mandrels for Testing Multimode Fiber

You should use mandrels when testing multimode fiber.
Mandrels can improve measurement repeatability and
consistency. They also allow the use of LED light sources
to certify 50 µm and 62.5 µm fiber links for current and
planned high bit-rate applications, such as Gigabit
Ethernet and 10 Gigabit Ethernet.

The gray mandrels included with some OptiFiber models
are compliant with TIA/EIA-568-B for 62.5 µm fiber with a
3 mm jacket.

Mandrels for 50 µm fiber are available from Fluke
Networks. Refer to the appropriate standard for mandrel
requirements if you follow other standards. The OF-500
Technical Reference Handbook provides a partial list of
mandrel requirements for TIA and ISO standards.

Figure 23 shows how to wrap the fiber around a
mandrel. Place mandrels on the tester’s output fibers, as
shown in Figures 25 through 32.

In the reference and test connection diagrams shown on
the tester, mandrels are indicated by a loop in the fiber.

Overview of Memory Functions

You can save test results on a removable memory card or
in the tester’s internal memory. The tester can use
multimedia cards (MMC) or secure digital cards (SD).

To select a location for saving tests, press S then
select CURRENT FOLDER on the Job tab.

Tip: To avoid confusion regarding the location of test

records, save test results on a memory card
whenever possible.

You can save results from any fiber test, except the real
time trace.

Each test record can hold bi-directional results from each
type of test (except ChannelMap, which you run in just
one direction). The test direction assigned to saved results
is determined by the THIS END setting (in Setup) used
when the test was run.

You can save the last test you ran anytime before you run
another test. This excludes FiberInspector images and
power meter results, which you must save at the time of
viewing.

If SAVE WARNING on the System tab is enabled, the
tester warns you if you are about to do something that
will delete an unsaved test from temporary memory. The
unsaved test is retained in temporary memory even if you
turn off the tester or remove the battery pack.

Memory Capacity and Card Sizes Supported

The number of test records you can save in a given
amount of memory space depends on what you save in
the records. For example, records that include video probe
endface images take more memory than records without
images.

The maximum amount of internal memory available for
test results depends on the space taken by the tester’s
software and custom limits.

Notes

Memory card folders can store a maximum of
500 records each.

Loss/length tests in Smart Remote mode take up
two records



one for each fiber.

Replacing the Battery

Replace the lithium ion battery pack when its life becomes
noticeably shorter. The battery is normally good for up to
400 charge/discharge cycles.

/Note

Dispose of the lithium ion battery pack in
accordance with local regulations.

An internal lithium battery maintains the tester’s clock
and other settings when you remove the battery pack.
This battery typically lasts about 5 years. When the battery
begins to fail, the tester will lose the current date and
time when you remove the battery pack. If the lithium
battery fails, send the tester to a Fluke Networks service
center for a replacement.

Cleaning

Clean the display with glass cleaner or isopropyl alcohol
and a soft, lint-free cloth. Clean the case with a soft cloth
dampened with water or water and a mild soap.

WCaution

To avoid damaging the display or the case, do
not use solvents or abrasive cleansers.

Storage

• Before storing the tester or an extra battery for an

extended period, charge the battery to between
70 % and 90 % of full charge (2 or 3 LEDs lit on the
battery’s gauge). Check the battery every 4 months
and recharge if necessary.

• Keep a battery attached to the tester during storage.

Removing the battery for long periods shortens the
life of the lithium battery that maintains the clock.

• See “Environmental and Regulatory Specifications”

on page 102 for storage temperatures.
