Cleaning and Connecting Optical Fibers

Cleaning and Connecting Optical Fibers

IMPORTANT

To ensure maximum power and to avoid erroneous readings:

 Always inspect fiber ends and make sure that they are clean 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.

Power Meter/Light Source/Optical Loss Test Set 17

Getting Started

Cleaning and Connecting Optical Fibers

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.

4 Measuring Power or Loss

(FPM-600 and FOT-600)

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.

Power Meter/Light Source/Optical Loss Test Set 19

1. From normal operating mode, press

repeatedly until you reach PM.

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

3. Press to switch between available
wavelengths. An asterisk (*) appears beside activated correction
factors. If no correction factor is set for a wavelength, the unit indicates
“----”.

Power Meter/Light Source/Optical Loss Test Set 23

Measuring Power or Loss (FPM-600 and FOT-600)

Referencing Your Power Meter to a Source

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 FOT-600 and FLS-600) 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 To change the
signal modulation: on page 35).

 If reference value or units change, the power meter beeps.

 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.

24 FPM/FLS/FOT-600

Measuring Power or Loss (FPM-600 and FOT-600)

Referencing Your Power Meter to a Source

To reference the power meter to a source manually:

1. Using the proper adapter, connect a light source (such as FLS-600 or

FOT-600) to the detector port of your power meter.

2. Activate the source at the desired wavelength.

3. Match the source and power meter

wavelengths:

 If the source emits an auto-wavelength

signal or is in auto-switching mode (see
Automatically Detecting Wavelength on
page 29 and Using Auto-Switching Mode
on page 35), the power meter automatically matches the source
wavelength.

OR

 Press to switch between pre-selected wavelengths (see

Defining a List of Favorite Wavelengths on page 22).

4. Hold down for a few seconds. The

Measuring Power or Loss

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 19).

2. Check and clean your fibers appropriately for optimum performance
(see Cleaning and Connecting Optical Fibers on page 17).

3. For loss measurements, reference your power meter to a light source
(see Referencing Your Power Meter to a Source on page 24), then
deactivate the light source.

4. Using the proper adapter and test jumpers, connect a fiber under test
to a light source (such as FLS-600 or FOT-600) 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.

Automatically Detecting Wavelength

Compatible sources (such as FOT-600 and FLS-600) 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 (FOT-600
and FLS-600: see Modulating the Source
Signal on page 34) or in auto-switching
mode.

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