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 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.

Getting Acquainted

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.

• ChannelMap

of the connectors and segment lengths in a channel.

• Optional FiberInspector

• 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 endface has about a 4% reflection. Holding a reflective surface near the connector endface 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.

• 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

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

WCaution

See Chapters 3 and 6 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 Chapter 5 or the tester’s online help 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.

Changing the 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 tester uses the index of refraction to determine fiber length.

You can change the index of refraction on the Cable tab in Setup.

When MANUAL CABLE SETTINGS on the Cable tab is disabled, the tester uses the n values specified in the selected fiber type.

When MANUAL CABLE SETTINGS is enabled, the tester uses the n values you enter.

The n values defined in the fiber types are suitable for most applications. Minor differences between the tester's n and a fiber's actual n usually do not make enough difference in length to fail a fiber.

You may want to change the index of refraction if

• The customer wants you to use a specific n value for

the job.

• The cable's fibers are longer than its jacket, and you

need to precisely locate a point on the cable (such as a fault). In this case, adjust n until the measured length matches a known length of fiber.

Increasing n decreases measured length.

Note

If you try to enter a value outside the valid range for n, the tester shows N/A for the value. The valid range is 1.1 to 1.71 inclusive.

To use the default n values specified in the selected fiber type, set MANUAL CABLE SETTINGS to Disabled.

About ANSI/TIA/EIA-606-A Fiber IDs

The following sections give basic examples of the 606-A IDs. For detailed information, including ID formats for other elements in cabling installations, contact the TIA to purchase a copy of the 606-A standard.

The examples use the following abbreviations:

• f = floor number

• s = telecom room letter

• a = patch panel letter

• n = For a horizontal link: port number

For a backbone: backbone cable letter or number

• d = copper pair or fiber strand number in backbone

cable

• b = building

Horizontal Link Identifier

Horizontal links run between telecommunications closets and work areas.

Format: fs-an

Example: 11C-D32

The link tested was on floor 11 in telecom room C, patch panel D, port 32.

Backbone Cable Identifier

Backbone cables run between telecommunication closets, usually on different floors.

Format: fs1/fs2-n.d

Example: 01B/5C-D.10

The fiber tested is in the backbone cable that runs between floor 1, telecom room B and floor 5, telecom room C. The backbone cable is cable D. The fiber tested is fiber 10 in backbone cable D.

Problem Solutions

The ID sequence is invalid. Verify that the types of characters in each position match between the start and stop IDs.

For example, using the letter “O” as the third character in the start ID and the number “0” as the third character in the end ID causes an error.

Verify that you are not trying to use accented characters as incrementing characters. You may use accented characters in IDs, but they must match between the start and stop IDs.

Verify that the start and stop IDs have the same numbers of characters. Verify that the START and STOP IDs do not generate a sequence with more than 3000 IDs.

When you press s, you cannot find the ID list.

After you press s, press A Pick ID; then press the appropriate softkey to see the list. You can access downloaded IDs only if the name of the current folder matches the folder

Cleaning the OTDR Connector

Note

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

Use a dry, optical-grade wipe to clean the OTDR connector. Figure 3-1 shows how to remove the OTDR adapter to access the connector ferrule.

The OTDR port connection quality screen helps you determine when the OTDR connector needs cleaning. See page 3-14.

If the connector is very dirty, wipe the end of the ferrule with an optical-grade wipe lightly moistened with 99 %pure isopropyl alcohol. Dry with a dry wipe.

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.

You can also switch between test modes by selecting Auto OTDR or Manual OTDR from the FUNCTIONS 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 “Using Manual OTDR Mode” on page 3-46 for details.

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.

OVERALL LOSS and FIBER LENGTH include the loss and length of the launch and receive fibers, unless you use the launch fiber compensation function.

3-3

OF-500 OptiFiber Certifying OTDR

Technical Reference Handbook

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.

Compensating for Launch and Receive Fibers

The launch fiber compensation function marks the end of the launch fiber and the beginning of the receive fiber, if used, on OTDR traces and labels these events in the event table. It also removes these fibers’ losses, lengths, and attenuation coefficients from overall OTDR results. The losses of the connections at the launch and receive fibers are not removed from the results.

Launch compensation also provides a more accurate ORL (optical return loss) measurement, provided that the correct backscatter coefficient for the fiber under test is entered on the Cable tab in SETUP.

The compensation function does not affect ChannelMap and real time trace results.

Types of Compensation

The tester offers three types of compensation:

• Launch Only: Lets you compensate for a launch fiber.

• Launch + Receive: Lets you compensate for a launch

fiber and a receive fiber.

• Launch + Fiber + Receive: Lets you compensate for a

launch and receive fiber if you have forgotten to do so before the receive fiber was taken to the other end of the cabling.

Notes

Launch + Receive compensation usually provides the most accurate measurements.

Avoid using Launch + Fiber + Receive compensation on fibers longer than 8 km. Doing so may degrade measurement accuracy.

* For singlemode modules, the 30 km range and an n value greater than 1.52 cause an error. These settings produce propagation times

that are beyond the tester’s range.

MANUAL CABLE SETTINGS

BACKSCATTER

When MANUAL CABLE SETTINGS is disabled, the n and BACKSCATTER values depend on the selected fiber type. When the MANUAL CABLE SETTINGS is enabled, the tester enters default values that you can change manually.

The n value is the index of refraction. Index of refraction is used to calculate length. The default n values defined in the fiber types are suitable for most applications. Minor differences between the default n and a fiber's actual n usually do not make enough difference in length to fail a fiber.

Increasing n decreases measured length.*

BACKSCATTER is the backscatter coefficient, which indicates the amount of light the fiber reflects back to the OTDR (using a 1 ns pulse). This value is used to calculate event reflectance for OTDR tests.

Enter the backscatter coefficient of the fiber under test, if known. This value is specified by many fiber manufacturers.

OTDR Connection Quality

When you run an OTDR test, the tester determines the quality of OTDR port connection (Figure 3-6).

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 3-7. 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.

Looking at OTDR Test Results

The tester offers three different views of OTDR test results: a summary, an event table, and an OTDR trace.

Table 3-2. OTDR SUMMARY Screen Features

Item Description

PASS/FAIL PASS: All test results are within limits.

FAIL: One or more test result exceeds the limits. See the OTDR trace or the event table for additional

information.

WARNING The value could not be reliably determined. These values are usually preceded by a "<" or ">" (less than

or greater than) symbol. This may occur if the fiber is too long, the signal is weak, or events are too close together to distinguish losses. In many cases, the OTDR DETAILS screens show causes of the warning. Press

C View Details to see these screens.

FIBER LENGTH The length of the fiber in the cabling. If the measured length seems wrong, check the index of refraction

on the Cable tab in Setup. The length does not include launch and receive fibers if launch fiber compensation is enabled.

Tip: In some cable types, some or all of the fibers may be longer than the cable jacket and some fibers

may be longer than others in the same cable. To adjust the length measurements to represent cable jacket length, change the index of refraction until the measured length matches the jacket length.
