Certification Information
North America Regulatory Statement
This unit was certified by an agency approved in both Canada and the United States
of America. It has been evaluated according to applicable North American approved
standards for product safety for use in Canada and the United States.
Electronic test and measurement equipment is exempt from FCC part 15, subpart B
compliance in the United States of America and from ICES-003 compliance in
Canada. However, EXFO Inc. makes reasonable efforts to ensure compliance to the
applicable standards.
The limits set by these standards are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the user guide, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Modifications not expressly approved by the manufacturer could void the user's
authority to operate the equipment.

PPM-350C 1
1 Introducing the PPM-350C
PON Power Meter
The PPM-350C PON Power Meter was designed for two main purposes:
Suit FTTP testing needs and to be easy to use for people who are not necessarily
familiar with fiber optics in FTTx.
Be used as a standard optical power meter (OPM operation mode).
Main Features
FTTx Operation Mode
Supports:
Port 1: 1310 nm (ONT)
Port 2: 1490 nm (OLT)/1550 nm (video)
Pass-through device (spy mode): does not block communication between ONT
and OLT.
Allows triple-play testing (voice, video and data).
Measures each signal independently: Optical Network Terminal (ONT) -
1310 nm; central office (CO) - 1490 nm and 1550 nm.
Measures optical power of any type of signal:
Continuous (for example, TV signal at 1550 nm)
Framed (for example, ATM, Ethernet at 1490 nm or 1310 nm)
All baud rates (for example, 155 Mbps, 1 Gbps; synchronous or
asynchronous)
Measures all signals simultaneously.
Features visual Pass/Fail indicators (one indicator per wavelength; all signal
statuses are displayed simultaneously).
Displays all power levels simultaneously.
Contains up to 10 different threshold sets (you can configure thresholds on a
computer and transfer them to your PPM-350C with a USB cable).
Introducing the PPM-350C PON Power Meter 2
Optical Power Meter (OPM) Operation Mode
3 calibrated wavelengths and up to 40 predefined wavelengths (from 1260 nm
to 1650 nm), each with their own correction factor.
Possible to take reference values for each of the available wavelengths.
Selectable unit (dB or dBm).
Other Useful Features
Automatically shuts down after 10 minutes of idle time (auto-off).
You can manage data directly on the unit (storing, recalling, deleting).
The Handheld Data Transfer (provided on your CD) 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 unit.
You can transfer the data (measurements) directly from your unit to a computer
using the USB port. This will allow you to view them with FastReporter, the
EXFO’s post-processing software.

Available Models
The PON Power Meter is offered in two wavelength/ ports configurations:
1310 nm (FTTx) / 1490 nm (FTTx/OPM)
1310 nm (FTTx) and 1490 nm/1550 nm (FTTx/OPM)
An optional VFL is also available.
Power Sources
The PON Power Meter operates with the following power sources:
AC adapter (connected to standard power outlet—indoor use only)
AA alkaline batteries (automatically take over if you unplug the AC adapter)
The icon also indicates the battery charge.
IMPORTANT
If the battery level becomes too low, the unit turns itself off.

Typical Applications
You can use your PON Power Meter in two modes:
FTTx mode: You can use your PPM-350C PON Power Meter during service
activation (at ONT) or to troubleshoot passive optical networks (at ONT, drop
terminal, fiber distribution hub or CO). This mode allows you to measure two or
three wavelengths simultaneously, depending on the configuration of the unit.
OPM mode: You can use your PPM-350C PON Power Meter to measure the
output power (in dBm) or loss (in dB) using one of the unit’s 40 CWDM
wavelengths available. This mode allows you to measure networks or devices
carrying only one wavelength.
