13

Setup - Manual (continued)

Note: The Range, Pulse Width, and Averaging Time parameters are user-selectable if the [Setup]
parameter is set to [Manual].

PARAMETER DESCRIPTION

Range

The Range parameter determines the distance range of the full (unzoomed) trace.
It also determines Resolution - the distance between data points in the trace: the
longer the range, the wider the data point spacing. We recommend selecting the
shortest distance range that is longer than the fiber under test. For example, to test
a fiber that is 1.5 km long (including launch and receive cables), select the 2 km
range. Available Range values:

Wavelength (nm) Distance Range Resolution (set by OTDR)

MM 850, MM 1300

SM 1310, SM 1550,
SM 1625

2 km (6561ft) 0.125 m (0.41 ft)

< 4 km (13123 ft) 0.25 m (0.82 ft)

8 km (26246 ft) 0.5 m (1.64 ft)
16 km (52493 ft) 1 m (3.28 ft)

32 km (104986 ft) range/16 km (range/5249 ft)

Pulse
Width

The M-series OTDR can operate using different pulse widths. Short pulse widths
provide the shortest event and attenuation dead zones. Long pulse widths provide
the best event detection on long fibers.

Averaging
Time

The [Time] parameter determines the duration of a timed test. Available time

settings: 5 • 10 • 30 • 60 • 90 • 180 sec

Setup: Real-Time Mode Settings

In addition to Core Settings, the Real Time mode allows you to set the Wavelength, Range, Pulse
Width, and Filter parameters.

OPM Operation - Testing Multimode/Single-mode Links

Step I - Set the Reference (One Jumper Method)

From the OTDR Main Menu, select the OPM (optical power meter) test mode. Turn on your OLS 1
(optical light source) and allow the light source to stabilize (minimum of 15 minutes).

If not using the [Wave ID] feature, set both instruments to the desired test wavelength.2

Select the appropriate fiber optic transmit and receive test jumpers. The fiber type of these 3
jumpers must match the fiber type of the link to be tested.

Perform one of the following:

For Multimode testing: wrap and secure the transmit jumper five times around the •
appropriate diameter mandrel.
For Single-mode testing: make a loop in a transmit jumper and secure it with a piece of tape. •
TIA testing - 30 mm loop
IS0 testing - 30-50 mm loop

Note: Clean both ends of the transmit jumper.

Connect the transmit jumper to the appropriate (MM or SM) output port of the OLS. 4

Mount an adapter cap on the OPM port that matches the free connector on the transmit jumper. 5

Connect the free end of the transmit jumper to the OPM port.6

If measured output power is outside of the normal range (specified by manufacturer), clean all 7
fiber connections or replace the transmit jumper. Repeat steps 4 - 7.

To set the reference level at the current wavelength, perform the following:8

Note: Do not disturb the transmit jumper at the OLS end.

If necessary, change the OPM adapter cap to match the connector on the receive jumper that 10
will be connected to the OPM test port.

Note: Clean both ends of the receive jumper.

Connect the receive jumper to the OPM test port.11

Mate the free ends of the transmit and receive jumpers using an appropriate adapter. 12

Verify that the insertion loss of this mated connector pair is under 0.75 dB, the maximum 13
allowed by the TIA and ISO (Noyes recommends 0.4 - 0.5 dB typical), as follows:

Observe

• the displayed loss level. This is the mated connector pair insertion loss of the test
jumpers in [dB].

If the insertion loss is not acceptable, disconnect the transmit and receive jumpers at the

•
adapter, clean the free ends of both test jumpers and repeat steps 12 & 13.

If the insertion loss is still not acceptable, replace both test jumpers and repeat steps 1-13. •

If the insertion loss is acceptable, disconnect the transmit and receive jumpers at the adapter.14

Move the OPM and OLS to opposite ends of the link to be tested.15

Step III - Measure Link Insertion Loss

Connect the free ends of the transmit and receive jumpers to the link under test.16

Note: Clean jumper end that connects to patch panel prior to every test.

The OPM will measure and display the insertion loss of the link under test.17

Press the [Save] key on the OPM to save the displayed measurement.18

Transferring Files

From OTDR via USB Function Port to PC

To transfer files from your OTDR to a PC using a USB cable, perform the following:

Connect your OTDR to a PC using the supplied mini-USB to USB cable. 1
Note: If your PC requests new USB drivers, install the CD-ROM that comes with your OTDR,
which contains the needed drivers. This step only needs to be performed the first time you
connect your OTDR and PC together.

If your PC pops up a dialog box asking if you want to set up a new Partnership, select No (the 2
OTDR should always be a ‘guest’).

Recommended Accessories

Fiber Optic Test Cables and Jumpers

Fiber optic test cables are necessary to connect an OTDR to the fiber under test ( FUT). Test cables
must have the same core and cladding size as the FUT. The connector at one end of the test cable
must mate with the appropriate optical port on the OTDR. The connector on the other end must
mate with the fiber optic link under test.

Launch and Receive cables are required to measure the insertion loss and reflectance of the near­end and far-end connectors respectively, of the fiber link being tested. Noyes Fiber Rings may be
used as Launch and Receive cables. Fiber Rings with a variety of lengths and connector styles are
available from AFL Telecommunications. The table on the next page will help in selecting the right
test jumpers or cables for testing.

Cleaning Tips

Clean Test Cables and FUT

It is important to keep connector end-faces on the launch and receive cables and those on the Fiber
Under Test (FUT ) clean, to ensure accurate measurements and operation.

IMPORTANT! Inspect optical connectors after cleaning to ensure cleaning was successful and to
verify the end-face is not damaged (cracked, pitted, etc.).

CAUTION! Never view a live fiber. Laser radiation is harmful to eyes.

Follow your company’s approved cleaning procedures.

AFL recommends cleaning test cables using a Cletop cassette cleaner or a One-Click Cleaner.

Cleaning the Optical Ports

CAUTION! Before conducting the following procedures be sure to have the OTDR turned OFF.

Cleaning the OTDR and VFL optical ports without removing the adapters

AFL One-Click Cleaner method

Remove the protective dust cover from the tip of the One-Click Cleaner. •

Insert the tip of the One-Click Cleaner into the optical port adapter and gently press the body of

•
the One-Click Cleaner until an audible “click” is heard.

Remove the One-Click Cleaner.

•

AFL FCC2 fluid and CCT stick method

Lean a can of FCC2 back (30°), press the button on FCC2 to fill the well. •

Dip a CCT stick into the well of the FCC2 to dampen the tip with optical cleaning fluid. •

Place the damp tip over the ferrule to be cleaned.

•

Rotate the tip clockwise 10 revolutions while applying varying pressure to create a gentle •
pumping action where the tip contacts the ferrule.

Discard the CCT stick after using both tips.

•

39

Cleaning the optical ports with adapters removed

Removing connector adapters for cleaning and inspection

To access the OTDR Port

Rotate the adapter base counterclockwise approximately four times. •

Pull the adapter directly out away from the universal adapter mount to expose the ferrule. •

To access the VFL Port

Unscrew the adapter counterclockwise and pull the adapter straight out to expose the ferrule.

To access the OPM Port

Unscrew the adapter cap from the adapter cap mount.

Cleaning the Exposed Ferrule or the OPM port

Use lint-free optical cleaning wipes such as AFL FiberWipes and optical quality cleaning fluid such as
AFL FCC2 connector cleaning fluid.

Note: if using isopropyl alcohol (IPA), be sure to use 99% pure IPA that has not been contaminated.

Dampen a portion of the wipe with the cleaning fluid.

1

Gently wipe the exposed ferrule (OPM port) starting with the wet section of the wipe and pulling 2
it to the dry section.

Note: • Starting with the wet cleaning and finishing in the dry improves cleaning action,
reduces static buildup, and finishes with the end-face dry.

Cleaning the adapters

Method 1:

Insert a Cletop adapter cleaning stick into the sleeve of the adapter and rotate 10 times. 1

Remove.2

After cleaning the adapter, replace the adapter over the ferrule; centering it onto the alignment 3
pin.

Tighten the adapter base.4

Method 2:

Use a can of filtered compressed air (held vertically), blow out any contaminates from the 1
adapter.

After cleaning the adapter, replace the adapter over the ferrule; centering it onto the alignment 2
pin.

Tighten the adapter base.3

FAQs

Can I save traces for viewing later?

Yes. There is a dedicated Save key. In the Main Menu “File tab”, set up the location/folder (Internal
or USB) to save the file, the file naming format, and fiber number. The fiber number will automatically
increment after each trace is saved.

What is the advantage of the Expert Auto mode?

User is able to select a single l and have the OTDR set the other test parameters.

What is the advantage of the Expert Auto Once mode?

User is able to select one or more wavelengths, let the OTDR select Pulse Width, Time, and Range
for one test. Then allow the user to adjust any of these test parameters for the next test(s).

What is the purpose of the Real-Time mode?

With a launch cable, the Real-Time mode may be used to quickly view many short fiber links. It can
also be used to quickly “trace” short fiber links.

Why do I need to use a launch and receive cable?

A launch cable allows the OTDR to settle down after the initial pulse and provides a reference cable
for testing the first connector on the fiber under test. A receive cable provides a reference cable for
testing the last connector of the fiber under test.

Tips: Expert OTDR Setup

RANGE: LENGTH

Too Short: you will not capture the entire fiber length •

Too Long: trace will be squashed to left side of Screen •

Good Range: 1.5 to 2 times length of actual fiber •

PULSE WIDTH:

Too Narrow: trace disappears into noise floor before end of fiber is reached •

Too Wide: events can not be resolved •

Good Pulse Width: Events can be seen and trace is smooth •

AVERAGES:

Too Few: Trace is noisy, trace floor is too high •

Too Many: Trace is smooth but wastes time •

Good Number of Averages: smooth trace •

Test in feet or meters?

If you know your fiber distances in feet, it may be beneficial to measure distances to events/faults in
feet.

Fiber loss specifications are given in dB/km. Therefore it is often beneficial to measure fibers in
meters/kilometers when loss results are required.

41

Recharging Batteries

The batteries may be charged while the OTDR is switched on or off by attaching an AC power
adapter.

Plug the AC adapter/charger into a standard wall outlet.

•

Connect the AC adapter/charger to the Power port located on the OTDR side panel.

•

The [AC/Charger] indicator on the front panel will turn on [Red]. •

Charge batteries until the [AC/Charger] indicator turns [Green]. •
