Page 3: Section 1: Introduction
INTRODUCTION BEFORE YOU BEGIN All personnel testing optical fibers should be adequately trained in the field of fiber optics before using any fiber optic test equipment. If the user is not completely familiar with testing fiber optics, they should seek competent training. Such training can be acquired from a variety of sources, such as local hands-on training classes. -
Page 4: Applications
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. -

If battery power is insufficient for operation, the unit will beep and then power off. BATTERY CHARGING The PON-2M is powered by (3) AA batteries, but can also operate on wall power when using an approved AC/DC power transformer with the following electrical... -
Page 10: Section 3: Test Procedures
TEST PROCEDURES SET THRESHOLDS Attaching the PON meter to a different point in the PON network will require a different set of thresholds for power measurements of PON wavelengths. It is important to set thresholds in the PON meter so that it can show PASS/FAIL/WARNING results. Up to 10 different threshold sets can be configured in the PON -2M PON power meter. -
