PO N-3
PON-3 is a portable, high quality PON optical power meter. It is
specifically designed to meet the rapid growth of the FTTx market
with PON (Passive Optical Network) technologies. It is capable of
measuring all three signals (1310nm, 1490nm and 1550nm) that
carry voice, data and video in a single fiber. The PON-3 can
measure not only 1490nm and 1550nm optical signal, but also
accurately detect and measure the upstream burst at 1310nm sent
from an ONU while the ONU is in the idle mode. The simple
operation and accurate measurements make the PON-3 an ideal tool
for PON suitable for APON, BPON, EPON and GPON applications,
installation/acceptance tests to ensure that they meet required
standards, and service activation/ troubleshooting.

PON-3 / Safety Information
3. Safety Information
Warnings!
Never look directly into optical outputs or a fiber while the equipment is ON. Invisible laser light will
cause permanent damage to your eyes.
Do not short-circuit the terminal of AC adapter / charger and the batteries. Excessive electrical
current may cause personal injury due to fumes, electric shock, or equipment damage.
Connect AC power cord with the equipment and wall socket properly. While inserting the AC plug,
make sure there is no dust or dirt on the terminals and both plugs are fully seated. Incomplete
engagement may cause fuming, electric shock or equipment damage and may result in personal
injury.
Do not operate the equipment near hot objects, in hot environments, in dusty/ humid conditions, or
when condensation is present on the equipment. This may result in electric shock, product malfunction,
or poor performance.

PON-3 / Discharged batteries
3.1 Discharged batteries
Remarks:
1) When the battery power is low, the warning indicator will blink. Replace the batteries or charge the
batteries using the AC adapter.
2) Please make sure that you have turned the instrument OFF before charging the batteries, unplug the AC
adapter when the batteries are fully charged.
3) Please make sure the batteries are correctly placed in the device before charging them.
4) To eliminate the possibility of battery acid leakage, please take out the batteries if the unit will not be used
for a long time.
6

PON-3 / AC Operation
3.2 AC operation
If the instrument is mainly used at one location, e.g. in a laboratory or test department, the AC adapter can be
used for power instead of batteries. There is a 12V DC input jack on the left side of the PON-3 device. When the
AC adapter is plugged in, the AC Indicator on the LCD will be displayed.
Note:
1 Power is supplied by the AC adapter even if the batteries are installed. The battery indicator will not be
displayed on the screen when AC adapter is plugged.
2 Make sure that the operating voltage of the AC Adapter / Charger is the same as the local AC line
voltage.

PON-3/ Preparing for Operation
4. Preparing for Operation
Unpacking the instrument
Packing material
We suggest that you keep the original packing material until you have checked the device and its contents
are in working order. Using the original packing material is your guarantee of protecting the instrument
during transit.
Checking the package contents
The standard accessories of PON-3 are as follows:
- PON-3 Device - FC and SC Adaptors
- Calibration Certificate - 4*Ni-MH Batteries
- Carrying Case - AC Charger
- USB Cable
Checking for damage in transit
After unpacking the instrument, check to see whether it was damaged in transit. If there is damage, do not
attempt to operate the instrument or to repair it without authorization. Doing so can cause further damage and
you may lose your warranty qualification.

5.3 Definitions
LEDs
The LED indicators provide a quick method to identify Pass, Fail, or Marginal readings without having to reading the LCD
screen. The three LED indicators represent: upstream 1310nm (ONU), downstream 1490nm (OLT) and 1550nm (Video)
respectively. The color codes are intuitive: RED = Fail; ORANGE = Warning; GREEN =Pass.
Thresholds for Pass / Fail
The definitions for the three states (Fail, Warning and Pass) are described as below:
There are 5 Threshold limits:
Limit1: PON-3 upper measurement capability of the meter
Threshold1: Maximum level for a Pass, Signal cannot be greater than this value
Threshold2: Minimum level needed for a Pass. Below this level is either a warning condition.
Threshold3: Lower limit for Fail. Below this level is a Fail condition.
Limit2: Lower limit of the PON-3 measurement capability of the meter

5.4 Quick Operation
1. Connect the instrument to the optical link under test.
2. Press the Power key to turn on the instrument.
3.Press the MENU key to enter the menu mode. Select the “Threshold” option using the dBm/dB key as the down
arrow and REF/SEL key to Select the option. Select the Threshold setting that applies to your application using the
same keys. Then press “MENU” to return.
4. The device will automatically make test measurements and display the results. Press the Mode key to select
the PASS / Fail display mode that is desired.

5.5 Detailed Operation
5.5.1 Powering On the Instrument
Press the Power key to turn on the instrument. It will automatically start making measurements. The auto-off feature
defaults to ON and is shown in the bottom of the LCD screen. If you want to turn it off, press the Power key and
release quickly (less than 2 seconds) to deactivate Auto shut down function. The auto shut down function means
the instrument will shut down automatically if the instrument has not been operated for a certain period of time. The
time period can be set under the menu functions. The default is 10 min.

PON-3 / Operation
5.5.2 Test mode:
In the test menu, press the Mode key to switch between the normal test mode and
Pass/Fail indicator mode.
1.Normal test mode
Normal test mode does not use the threshold values and just displays the optical power
measurements. In this mode, the LED indicators will not light. The results are displayed
in either dB or dBm. Use the dB/dBm key to switch the units. See Fig. 1.
10-03-03 11: 43:15
Auto off
dBm units display the absolute power level
dB units display a power level relative to a Reference value . In this mode, a reference
value needs to be preset.
2.P/F test mode
The P/F test mode compares the measured light to preset threshold values. The LCD will
display the optical power and current Pass/Warning/Fail state. The LED indicators below
the LCD display will also change color to match the current P/F state. See Fig. 2.

5.5.3 Threshold Setup
The user can select from 10 different Threshold settings that have been preset. The Threshold values are set up
using the PC software and cannot be entered from the meter. A threshold name can also be assigned using the PC
software. The PC software can be obtained from the ComSonics website, www.comsonics.com, under the resources
download section.
In the Threshold menu view, the top line indicates system information (date & time) and the bottom line indicates
the threshold information including threshold number and name. Press “Up” (MODE) and “Down” (dBm/dB) to
toggle through the preset group of the thresholds and press “REF/SEL” to select the desired Threshold settings.
After completing this operation, all P/F mode test results will be based on this threshold value.
An example of the PC software that allows the user to set the Threshold values is shown below:

5.5.4 Time Setup
In the Menu mode, choose "Time" to setup up the data and time, see Fig. 4.
10-03-03 11: 43:15
Fig.4 Time Setup Menu
In the time setup menu, the Save key becomes the left arrow key - use it to move the cursor. When the cursor
moves to a number, the user can use ▲ key to increase value and ▼ to decrease value. When cursor moves to
“Yes”, press the REF/SEL key for more than 2 seconds, the “Yes” will flash which means the instrument has
accepted the time change. During the time setup, the user can press Menu key (less than 2 sec) to exit the time
menu and return back to test menu. The system time remains unchanged.

5.5.5 dBm/dB Key for Unit Switching
When the instrument is in the normal test mode, pressing dBm/dB can switch the units between dBm and
dB. The dBm unit is the actual absolute power and dB unit is a power value relative to reference value. Refer
to next section about “Reference value setup”.
When the instrument is in the Pass/Fail test mode, pressing dBm/dB key will automaticallyexit P/F test mode
and switch to normal test mode. The units will default to dB.
