Available Models
The PPM-350B PON Power Meter is offered in one- and two-port configurations with
normal or extended measurement range. The extended range allows testing at the
central office and before the splitter.
Some models support relative-power measurement allowing you to measure loss
between two locations.
Power Sources
The PPM-350B PON Power Meter operates with the following power sources:
³ AC adapter (connected to standard power outlet—indoor use only)
³ AA alkaline batteries (automatically take over if you unplug the AC adapter)
The icon also indicates the battery charge.
Typical Applications
You can use your PPM-350B PON Power Meter during service activation (at ONT) or
to troubleshoot passive optical networks (at ONT, drop terminal, fiber distribution
hub or CO).
IMPORTANT
If the battery level becomes too low, the unit turns itself off.

3 Getting Started with Your
PPM-350B PON Power
Meter
Turning the Unit On and Off
When you turn the PPM-350B PON Power Meter off, it saves the current mode
(Pass/Fail or Normal) and threshold set. On models supporting relative-power
measurement, unit and reference values are also kept in memory.
Note: Offset nulling values are always returned to factory settings.
To t u r n t h e un i t on :
Press . The unit displays EXFO for a few seconds and vertical bars move at the
top of the display, indicating the initialization is in progress. You may use your unit
immediately under normal conditions. The unit is in Pass/Fail or Normal mode,
depending on which mode was used last time.
To turn the unit off:
From Pass/Fail or Normal modes (not threshold selection mode or correction factor
mode), hold down 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.

Activating Automatic Shutdown (Auto-Off)
When auto-off is activated, the unit will turn itself off
after 10 minutes of idle time.
Auto-off is activated by default when you turn unit on.
To deactivate/reactivate auto-off:
Press .
PRESS: Turns unit on
Controls auto-off
Exits special modes
HOLD: Turns unit off
PRESS: Switches between
measurement units and
deactivates Pass/Fail mode
HOLD: Displays correction factors
PRESS: Displays reference values for a few
seconds, then switches units to dB and
deactivates Pass/Fail mode.
HOLD: Sets input power as reference power
for all wavelengths
Accesses threshold selection

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, as shown below:
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.
