INTRODUCTION
APPLICATIONS
Below is a list of test and measurement applications that can be performed using the PON-2M PON (passive optical network) power
meter. The procedure for each one of these applications is covered in detail in this manual.
PON Optical Power Measurements.
FTTH networks should be measured to ensure that the power levels received from the ONT
(optical network terminal) and OLT (optical line terminal) are sufficient for accurate and reliable transmission.
Active Equipment Optical Power Measurements.
Active equipment should be measured periodically for correct power levels.
The transmitters in this equipment have a known power value. The PON-2M can be directly attached to this equipment via a patch
cord to check whether the transmitter is within the manufacturer’s specified power range.
Fiber Continuity Testing.
Continuity can be measured with the PON-2M by placing a calibrated light source on one end of the fiber
and the PON-2M on the other end. This is also a simple way to measure the attenuation of the fiber.
This manual describes the operation of the PON-2M PON power meter.
The PON-2M is a very economical option for measuring the output power of ONT and OLT in FTTx PON networks. The PON-2M is
NIST traceable, and is calibrated 1310, 1490, and 1550nm. Up to 10 threshold levels can be set for different measurement points on
the FTTH network.
Its user-friendly interface includes nine push-buttons to cover all the functions of the PON-2M. Up to 100 readings can be stored in
internal memory, which can be retrieved on the LCD display at a later time.
The PON-2M includes two SC connectors – one for connection to OLT and one for connection to the ONT. An internal pass-through
allows for all three FTTx wavelengths to be measured simultaneously when the network is in operation.
The PON-2M is powered by (3) AAA batteries, which allows for 36 hours of battery life.
At additional cost, a model is available that allows data to be downloaded via USB to a PC in Excel spreadsheet format using
download software.
