3Getting Started
Turning the Unit On and Off
When you turn off the FPM-600, it saves the current wavelength, unit
and reference power. It also saves the Hold Min/Max power mode if
activated.
Note: Offset nulling values are always returned to factory settings.
To turn on the unit:
Press . The unit displays EXFO Inc. for a few seconds. You may use it
immediately under normal conditions.
To turn off the unit:
a few seconds.
IMPORTANT
If you remove batteries (and the AC adapter is unplugged), the unit
will turn off without saving the above values.
If batteries are low (and the AC adapter is unplugged), the unit will
save the above values and turn off.
From normal operating mode, hold down
WARNING
When the ACTIVE LED on your unit is on, the laser source is active
and emitting light. Do not look directly into a live fiber, and ensure
that your eyes are protected at all times.

Installing the EXFO Universal Interface (EUI)
The EUI fixed baseplate is available for connectors with angled (APC) or
non-angled (UPC) polishing. A green border around the baseplate
indicates that it is for APC-type connectors.
To install an EUI connector adapter onto the EUI baseplate:
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.

Getting Started
Cleaning and Connecting Optical Fibers
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.
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.

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.
