Cleaning and Connecting Optical Fibers

IMPORTANT

To ensure maximum power and to avoid erroneous readings:

³ Always clean fiber ends as explained below before inserting

them into the port. EXFO is not responsible for damage or errors
caused by bad fiber cleaning or handling.

³ Ensure that your patchcord has appropriate connectors. Joining

mismatched connectors will damage the ferrules.

To connect the fiber-optic cable to the port:

1. Clean the fiber ends as follows:

1a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl alcohol.

1b. Use compressed air to dry completely.

1c. Visually inspect the fiber end to ensure its cleanliness.

2. Carefully align the connector and port to prevent the fiber end from touching the

outside of the port or rubbing against other surfaces. If your connector features
a key, ensure that it is fully fitted into the port’s corresponding notch.

3. Push the connector in so that the fiber-optic cable is firmly in place, thus
ensuring adequate contact.

If your connector features a screwsleeve, tighten the connector enough to firmly
maintain the fiber in place. Do not overtighten, as this will damage the fiber and
the port.

Note: If your fiber-optic cable is not properly aligned and/or connected, you

will notice heavy loss and reflection.

4 Measuring Power or Loss

(EPM-500 and EOT-500)

Nulling Electrical Offsets

Temperature and humidity variations affect the performance of electronic circuits
and optical detectors. Nulling the electrical offsets eliminates these effects. Your unit
has been designed not to require offset nulling under normal operation, but you
should perform it whenever environmental conditions change significantly or when
measuring very low power values.

IMPORTANT

If light reaches the detector when nulling offsets, LIGH appears on
the display and the nulling is not performed. You will need to press a
key to return to the previous display.

Note: Factory-defined values will be reinstated when you turn off the unit.

To perform an offset nulling:

Hold down a few seconds. The unit displays NULL
while nulling the offsets, then returns to normal mode.

Note: Keypad is disabled during the operation.

EPM-500/ELS-500/EOT-500 10

Measuring Power or Loss (EPM-500 and EOT-500) 11

Referencing Your Power Meter to a Source

In reference mode, your unit displays the loss created by the fiber under test only,
since a reference value is subtracted from the measured power.

Note: You must set a reference value separately for each wavelength.

Compatible sources (such as EOT-500 and ELS-500) can transmit a power value to
your power meter, avoiding the need for manual referencing.

IMPORTANT

The value sent is not the source’s actual power. It is a user-defined
value that may not take the optical link’s loss into account.

To receive the reference power value from a compatible source:

1. Connect a compatible source to your power meter

(as shown below, with or without a fiber under
test).

2. Use the source to emit the signal that contains its
power value (see Sending Source Power Value
with Signal on page 18).

³ If reference value or units change, the power

meter beeps.

³ The new reference power is displayed in the top right corner (in dBm) and

current loss reading is automatically switched to dB.

Note: When using this feature, you cannot change the power meter’s

wavelength manually. The power meter behavior is totally determined
by the source.

To reference the power meter to a source manually:

1. Using the proper adapter, connect a light source (such as ELS-500 or EOT-500)

to the detector port of your power meter.

3. Match the source and power meter wavelengths:

³ If the source emits an auto-wavelength signal

or is in auto-switching mode (see
Automatically Detecting Wavelength on
page 14 and Using Auto-Switching Mode on
page 17), the power meter automatically
matches the source wavelength.

³ Press to switch between calibrated wavelengths.

4. Hold down a few seconds. The power meter
stores the currently detected power as the new
reference power.

Reference power is displayed in the top right
corner (in dBm) and current loss reading is
automatically switched to dB.

5. Repeat the procedure for each wavelength you
want to reference (if you use auto-switching mode, the power meter
automatically references wavelengths one at a time).

Note: When using dB units, press to display the current wavelength for a

few seconds. To change this wavelength, press again while it is
displayed.

Measuring Power or Loss

Measuring absolute power or link loss is done the same way, except for the
referencing step.

To perform power or loss measurements:

1. If necessary, perform an offset nulling (see Nulling Electrical Offsets on page 10).

2. Check and clean your fibers appropriately for optimum performance

(see Cleaning and Connecting Optical Fibers on page 9).

3. For loss measurements, reference your power meter to a light source
(see Referencing Your Power Meter to a Source on page 11), then deactivate the
light source.

4. Using the proper adapter and test jumpers, connect a fiber under test to a light
source (such as ELS-500 or EOT-500) and to the detector port of your unit.

Note: If you have referenced your power meter to a source, simply connect a

fiber under test to the test jumpers used for referencing.

When the unit detects a modulated signal, it beeps and displays the modulation
value and average measured power or loss (see left illustration above). You may
notice a slightly unstable last digit.

7. If necessary, change the displayed units by pressing .

8. Repeat the procedure for other wavelengths.

Automatically Detecting Wavelength

Compatible sources (such as EOT-500 and ELS-500) can transmit their wavelength
value through the fiber, avoiding the need to manually match the source and power
meter wavelengths.

Note: When you receive an auto-wavelength signal or when the source is in

auto-switching mode, you cannot manually change the power meter
wavelength. The power meter behavior is totally determined by the
source.

To receive the auto-wavelength signal or detect the source's
auto-switching mode:

1. Connect a compatible source to your power meter.

2. Activate the source in Auto mode (EOT-500 and

ELS-500: see Modulating the Source Signal on
page 17) or in auto-switching mode (see Using
Auto-Switching Mode on page 17).

Your power meter automatically matches the
source wavelength. If the wavelengths differ, it also
beeps and returns you to normal operating mode.

Measuring Power or Loss (EPM-500 and EOT-500) 15

Setting Pass/Fail Thresholds

You can define thresholds to specify acceptable power (dBm) or loss (dB) values for
each wavelength. Thresholds are often supplied by system manufacturers and
depend on the system deployed.

When a threshold is activated, the PASS/FAIL LED
is turned on. If it is green, the threshold
succeeded, if the PASS/FAIL LED is red, the
threshold failed.

To set pass/fail thresholds:

1. From normal operating mode, press

repeatedly until you reach PM.

2. Press to access the first submenu, then press

3. Press to switch between power (dBm) and

will lighten (green or red) when you return to normal mode.

6a. Hold down a few seconds. The first digit of the threshold blinks.

6b. Clear all digits by holding down a few seconds.

AND/OR

Select a digit to change by holding until it blinks, then increase its
value by pressing (it returns to 0 after 9). After the last digit, all digits
blink: you may add/remove the “–” sign by pressing .

6c. While a digit blinks, hold down a few seconds to save the modified

value (it remains in memory even when you turn off the unit) or press
to return to the previous value without saving.

5 Using a Light Source

(ELS-500 and EOT-500) or
VFL

The ELS-500 may contain up to three sources (one-port models) or up to four
sources (two-port models). The EOT-500 may contain up to three sources.

Note: The VFL option may also be present on the EPM-500.

Activating/Deactivating a Light Source or VFL

Only one source may be active at a time. When no source is active, the unit displays
OFF.

Modulating the Source Signal

When you activate the first source (after turning on the unit), the signal is always
CW (unmodulated). When you switch sources, the modulation remains the same
(VFL remembers its own modulation). Modulation is indicated in the top left
(port #1) or top right (port #2) corner.

Available modulation values are: CW, Auto, auto-switching mode, 270 Hz, 1 kHz and
2kHz (VFL: CW and 1Hz only).

Note: Auto is a modulated signal detected by compatible units (see

Automatically Detecting Wavelength on page 14). It provides greater
autonomy than CW, but covers a reduced power range.

Note: Auto-switching mode is a special signal detected by compatible units

To change the signal modulation:

1. Activate the source.

2. Press to switch between available

(see Using Auto-Switching Mode on page 17).

modulations.

Using Auto-Switching Mode

In auto-switching mode, your source automatically
switches from one wavelength to another. The power
meter connected to this source displays the power
value for each wavelength one at a time. The
wavelength value appearing on the display changes
every two seconds.

To activate auto-switching mode:

1. Press to activate the source.

2. Press to switch between available modulations until the Auto indicator

blinks on your display.

Sending Source Power Value with Signal

Your source can transmit a user-defined power value to compatible power meters
(such as EOT-500 and EPM-500) through the fiber. If the reference source is far from
the power meter, you can connect your source to the power meter to send the
reference value. With this feature you can also correct for power variations.

Note: If you connect a fiber between EOT-500’s source and detector ports, the

unit can use the actual source output power as reference power.

Note: For details about how compatible power meters receive this power

value, see Referencing Your Power Meter to a Source on page 11.

IMPORTANT

The value sent is not (and will not affect) the source’s actual power.
It is a user-defined value that may not take the optical link’s loss into
account.

To define the source power value to use as reference:

1. From normal operating mode, press repeatedly until you reach SRC.

2. Press to access the first submenu, then press repeatedly until you

reach the PREF menu.

3. Press to switch between available source wavelengths and select one. The
unit displays the currently defined power value for this wavelength.

4. Edit the power value as follows:

4a. Hold down a few seconds. The first digit of the power value blinks.

4b. Revert all digits to 0 by holding down a few seconds.

AND/OR

Select a digit to change by pressing until it blinks, then increase its
value by pressing (it returns to 0 after 9). After the last digit, all digits
blink: you may add/remove the “–” sign by pressing .

4c. While a digit blinks, hold down a few seconds to save the modified

value (it remains in memory even when you turn off the unit) or press
to return to the previous value without saving.

5. Press twice to exit setup menus.

4. Gently turn the cleaning tip one full turn, then continue to turn as you withdraw
it.

5. Repeat steps 3 to 4 with a dry cleaning tip.

Note: Make sure you don’t touch the soft end of the cleaning tip.

6. Clean the ferrule in the connector port as follows:

6a. Deposit one drop of isopropyl alcohol on a lint-free wiping cloth.

IMPORTANT

Since isopropyl alcohol is not absolutely pure, it may leave residues
if used abundantly or left to evaporate (about 10 seconds).

Avoid contact between the tip of the bottle and the wiping cloth,
dry the surface quickly, and use a bottle that distributes only a drop
of alcohol at a time.

6b. Gently wipe the connector and ferrule.

6c. With a dry lint-free wiping cloth, gently wipe the same surfaces to ensure

that the connector and ferrule are perfectly dry.

6d. Verify connector surface with a portable fiber-optic microscope

(e.g., EXFO’s FOMS) or fiber inspection probe (e.g., EXFO’s FIP).

WARNING

Verifying the surface of the connector WHILE THE UNIT IS ACTIVE
WILL result in permanent eye damage.

calibration validity period can be longer or shorter depending on the intensity of use,
environmental conditions and unit maintenance. You should determine the
adequate calibration interval for your unit according to your accuracy requirements.

Under normal use, EXFO recommends calibrating your unit every year.

Note: The FlexCare warranty program includes Calibration/Verification

packages (see Service and Repairs on page 38).
