1. Hold the EUI connector adapter so the dust cap opens downwards.

2. Close the dust cap in order to hold the connector adapter more firmly.

3. Insert the connector adapter into the baseplate.

4. While pushing firmly, turn the connector adapter clockwise on the baseplate to

lock it in place.

Cleaning and Connecting Optical Fibers

IMPORTANT

To ensure maximum power and to avoid erroneous readings:

 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.

 Ensure that your patchcord has appropriate connectors. Joining

mismatched connectors will damage the ferrules.

To connect the fiber-optic cable to the port:

1. Inspect the fiber using a fiber inspection microscope. If the fiber is clean,

proceed to connecting it to the port. If the fiber is dirty, clean it as explained
below.

2. Clean the fiber ends as follows:

2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl alcohol.

2b. Use compressed air to dry completely.

2c. Visually inspect the fiber end to ensure its cleanliness.

3. 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.

4. 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.

EXFO uses good quality connectors in compliance with EIA-455-21A standards.

To keep connectors clean and in good condition, EXFO strongly recommends
inspecting them with a fiber inspection probe before connecting them. Failure to do
so will result in permanent damage to the connectors and degradation in
measurements.

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 the unit off.

To perform an offset nulling:

Hold down and a few seconds.

The unit displays NULL and vertical bars move at
the top of the display, indicating the nulling is in
progress.

Note: Keypad is disabled during the operation.

The unit will then return to your previous mode (Pass/Fail or Normal).

4 Configuring Thresholds,

Correction Factors,
Wavelength List, and
Storage Details

Your PPM-350C PON Power Meter has been configured by EXFO with predefined
information:

 Threshold sets that you use in FTTx mode. Up to 10 sets are available.

A threshold set consists of the number of wavelengths (2 or 3) depending on
your unit. For each wavelength, you can select the pass, warning and fail
criteria.

 Correction factors for the FTTx mode and OPM mode. These are set to 0 dB

since they were properly calibrated at EXFO.

Correction factors are added to the measured values. For this reason, once the
correction factors are applied, your PON Power Meter may display “HI” or “LO”,
indicating the power levels are no longer within the unit’s power limits.

If you need to define correction factors of more than 1 dB or less than –1 dB to
compensate for inaccuracies, it may be a good idea to send your PON Power
Meter for recalibration (see Recalibrating the Unit on page 27). This will ensure
the results remain accurate.

 A wavelength list consisting of 1310 nm, 1490 nm and 1550 nm for OPM

operations. This list may contain up to 40 wavelengths (from 1260 nm to
1650 nm)

 Predefined storage information used in FTTx and OPM operations such as OLT

names, ONT names and LOC ID names.

You may customize these parameters using the Handheld Data Transfer (HHDT)
software provided on your CD.

The Handheld Data Transfer enables you to create new threshold sets and
correction factors, define your list of favorite wavelengths, as well as set storage and
job options for better data management, or modify values retrieved from your PON
Power Meter. You can configure your PPM-350C with up to 32 OLTs, 255 ONTs,
16 LOCs and 32 JOBs. For more information, refer to the Handheld Data Transfer
online help.

IMPORTANT

Thresholds, correction factors, wavelength list, as well as storage
and job options will be transferred to your unit. Previous values will
be lost.

Working in FT Tx Mode 14

5 Working in FTTx Mode

You can use this mode during service activation (at ONT) or to troubleshoot passive
optical networks (at ONT, drop terminal, fiber distribution hub or CO). You can
measure two or three wavelengths simultaneously, depending on the configuration
of the unit.

Selecting a Threshold Set

You can select which threshold set will be used to determine the Pass/Warning/Fail
status. Your unit contains up to 10 threshold sets, but only one set can be selected at
a time.

Depending on the model of the unit, a threshold set comprises two or three
wavelengths (1310 and 1490 nm; 1310, 1490, and 1550 nm), each of them having
specific threshold values for pass, warning and fail.

Note: Thresholds are used in Pass/Fail mode only.

You can view thresholds directly on your unit. To modify threshold values, you must
use the Handheld Data Transfer (refer to the Handheld Data Transfer online help).

6 Working in OPM Mode

Your unit can also be used as a standard optical power meter (in the OPM mode).
This is particularly useful if you want to measure networks or devices carrying only
one wavelength.

 You can measure the output power (in dBm) or loss (in dB) using one of the

unit’s 40 CWDM wavelengths available.

You can select the wavelength that you want to use for your measurements. To
customize the list of available wavelengths, you must use HHDT (refer to the
online help of the HHDT application for more information).

 You can set a specific reference value for each wavelength of the list. This

reference value will remain in memory until you store a new one for the same
wavelength.

When you use reference, your unit displays the loss created by the fiber under
test only, since it subtracts a reference value from the measured power.

To perform loss measurements:

1. Clean your fibers properly as explained in Cleaning and Connecting Optical

Fibers on page 11.

2. Connect the fiber to the OLT/video port.

3. Tu r n un i t on .

4. Select the OPM mode, by pressing and holding down a few seconds.

5. Select the test wavelength by pressing

or until the desired wavelength

is displayed.

6. Press to select dB, so that the loss is
expressed in dB.

7. Hold down for a few seconds to take the
reference.

The reference indicator is displayed, showing that the new reference value is
now stored in memory.

Loss measurement is displayed just under the reference value.

8 Identifying Fiber Faults

Next

Next

Visually

Note: This feature is available only if your unit is equipped with a VFL port.

The visual fault locator (VFL) helps you identify bends, faulty connectors, splices
and other causes of signal loss.

From its dedicated port, the VFL emits a red signal which becomes visible at the
location of a fault on the fiber. This signal can be continuous (the default) or blinking
(1 Hz).

WARNING

When the VFL is active, the VFL port emits visible laser radiation.
Avoid exposure and do not stare directly into the beam. Ensure that
any unused port is properly protected with a cap.

When the VFL is on, the rightmost status LED will also be on.

To activate the VFL and inspect a fiber:

1. Connect the fiber under test to the VFL port (see Cleaning and Connecting

Optical Fibers on page 11).

2. Press and hold down for a few seconds to switch between ON CW
(continuous signal) and ON 1HZ (blinking signal).

3. Without looking directly into the beam, examine the fiber. If light is coming out
of the rubber jacket or on the side of the ferrule, the fiber is defective.

4. Deactivate the VFL by pressing and holding down for a few seconds to
switch between the signals (ON CW and ON 1HZ), until you reach OFF.

Regular cleaning of EUI connectors will help maintain optimum performance. There
is no need to disassemble the unit.

IMPORTANT

If any damage occurs to internal connectors, the module casing will
have to be opened and a new calibration will be required.

To clean EUI connectors:

1. Remove the EUI from the instrument to expose the connector baseplate and

ferrule.

2. Moisten a 2.5 mm cleaning tip with one drop of isopropyl alcohol (alcohol may
leave traces if used abundantly).

3. Slowly insert the cleaning tip into the EUI adapter until it comes out on the other
side (a slow clockwise rotating movement may help).

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

PPM-350C 25

Maintenance 26

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 (for

example, EXFO’s FOMS) or fiber inspection probe (for example, EXFO’s
FIP).

WARNING

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

7. Put the EUI back onto the instrument (push and turn clockwise).

8. Throw out cleaning tips and wiping cloths after one use.

Replacing Disposable Alkaline Batteries

+

+

+

overheating, or even explosion.

CAUTION

EXFO guarantees the specifications and viability of the products
ONLY if they are used with chargers provided by EXFO.

Recalibrating the Unit

Manufacturing and service center calibrations are based on the ISO/IEC 17025
Standard, which states that calibration documents must not contain a
recommended calibration interval, unless this has been previously agreed upon
with the customer.

Validity of specifications depends on operating conditions. For example, the
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 three years.

Note: The FlexCare warranty program includes Calibration/Verification

PPM-350C 27

packages (see Service and Repairs on page 37).
