Power Meter and VFL3
Using the Optional Power Meters and VFL
Nulling Offsets
Nulling Offsets
Temperature and humidity variations affect the performance of electronic
circuits and optical detectors, which can offset measurement results. To
compensate for this offset, the unit is equipped with an offset nulling
function.
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
Light must not reach the detector when nulling offsets. Always use
an EUI or protective screw cap. Do not use a soft rubber cover.
To perform an offset nulling:
1. Tighten the protective cap on the power meter port.
2. From the Instrument View tab, tap Offset Nulling.
The nulling process may take a moment, depending on the type of power
meter you are using.
4Power Meter and VFL
Using the Optional Power Meters and VFL
Setting Thresholds and Correction Factors
Setting Thresholds and Correction Factors
You can define thresholds to specify acceptable power or insertion loss
values for each wavelength. Thresholds are usually supplied by system
manufacturers and depend on the system deployed.
When the measurement status is “Pass”, the value is displayed in green in
the Instrument View tab, on the Measurements list, and in reports.
When the measurement status is “Fail”, the value is displayed in white over
a red background in the Instrument View tab, on the Measurements list
and in reports.
Note: A power measurement (in dBm) will be considered as “Fail” when its value
is outside the defined absolute power threshold.
Note: An insertion loss measurement (in dB) will be considered as “Fail” when its
value is greater than the insertion loss threshold.
You must select the pass/fail status feature for the application to take into
account the defined thresholds and display the appropriate status icons. By
default, this feature is not selected.

Using the Optional Power Meters and VFL
Setting Reference Values on Your Power Meter
Setting Reference Values on Your Power Meter
In Reference mode, your unit displays the loss created by the fiber under
test only, since it subtracts a reference value from the measured power.
You can set a different reference value for each wavelength. A reference
value remains in memory until a new one is stored at the same
wavelength.
If the source and power meter you are using has auto-wavelength or
auto-switching capacity, you can take the reference value automatically for
each wavelength as well.
To set reference values to use in Reference mode:
1. Check your fibers and clean them properly.
2. Using the proper adapter and test jumpers, connect a light source to
your power meter.
3. From the Instrument View tab, select the wavelength in the list.
Activate the source at the same wavelength.
OR
If you want to use the auto-wavelength or auto-switching mode, enable
it on the source, then select Auto in the wavelength list (for more
information on the auto-wavelength or auto-switching mode, see
Measuring Power or Insertion Loss on page 10).
4. Ta p Reference to save the current power value as the new reference. It
will appear on the upper-right corner of the data display.

Measuring Power or Insertion Loss
Measuring Power or Insertion Loss
Measuring absolute power or link (insertion) loss is done the same way,
except for the referencing step. You can take power or insertion loss
measurements and save them for further analysis.
IMPORTANT
If you intend to take measurements with a very low power level
using the built-in power meter, make sure that your testing
conditions are optimal to ensure the best results (for example, do
not use the VFL).
You can either perform measurements manually and select each
wavelength yourself, or you can use the auto-wavelength and
auto-switching modes of your source, if the model allows it.
Note: Not all power meters have auto-wavelength and auto-switching detection
capacities. If the auto mode is not available, you cannot select it in the
Wavlength list. However, if the power meter has the capacity, but the auto
mode is still not available, a firmware update may be required. Please
contact EXFO to see how to proceed to update the firmware.

Identifying Fiber Faults Visually with the VFL
Identifying Fiber Faults Visually with the VFL
The optional visual fault locator (VFL) helps you identify bends, faulty
connectors, splices and other causes of signal loss. It can also help the
person at the other end of the link to identify the fiber under test, which
could be particularly useful when working with cables containing many
fibers.
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 (CW) 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. Protect any
unused port with a cap.

Maintenance and Troubleshooting
Recalibrating the Unit
Recalibrating the Unit
EXFO manufacturing and service center calibrations are based on the
ISO/IEC 17025 standard (General Requirements for the Competence of Testing and Calibration Laboratories). This standard states that calibration
documents must not contain a calibration interval and that the user is
responsible for determining the re-calibration date according to the actual
use of the instrument.
The 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, as
well as the specific requirements for your application. All of these elements
must be taken into consideration when determining the appropriate
calibration interval of this particular EXFO unit.
Under normal use, the recommended interval for your Power Meter and
VFL is: one year.
For newly delivered units, EXFO has determined that the storage of this
product for up to six months between calibration and shipment does not
affect its performance (EXFO Policy PL-03).
26Power Meter and VFL
Maintenance and Troubleshooting
Recalibrating the Unit
To help you with calibration follow-up, EXFO provides a special calibration
label that complies with the ISO/IEC 17025 standard and indicates the unit
calibration date and provides space to indicate the due date. Unless you
have already established a specific calibration interval based on your own
empirical data and requirements, EXFO would recommend that the next
calibration date be established according to the following equation:
Next calibration date = Date of first usage (if less than six months
after the calibration date) + Recommended calibration period (one
year)
To ensure that your unit conforms to the published specifications,
calibration may be carried out at an EXFO service center or, depending on
the product, at one of EXFO’s certified service centers. Calibrations at
EXFO are performed using standards traceable to national metrology
institutes.
Note: You may have purchased a FlexCare plan that covers calibrations. See the
Service and Repairs section of this user documentation for more
information on how to contact the service centers and to see if your plan
qualifies.
