Cleaning and Connecting Optical Fibers IMPORTANT To ensure maximum power and to avoid erroneous readings: Always clean fiber ends as explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling. Ensure that your patchcord has appropriate connectors. Joining mismatched connectors will damage the ferrules. To connect the fiber-optic cable to the port: 1. Inspect the fiber using a fiber inspection microscope.
Getting Started with Your PON Power Meter 12 Nulling Electrical Offsets Temperature and humidity variations affect the performance of electronic circuits and optical detectors. Nulling the electrical offsets eliminates these effects. Your unit has been designed not to require offset nulling under normal operation, but you should perform it whenever environmental conditions change significantly or when measuring very low power values.
4 Configuring Thresholds, Correction Factors, Wavelength List, and Storage Details Your PPM-350C PON Power Meter has been configured by EXFO with predefined information: Threshold sets that you use in FTTx mode. Up to 10 sets are available. A threshold set consists of the number of wavelengths (2 or 3) depending on your unit. For each wavelength, you can select the pass, warning and fail criteria. Correction factors for the FTTx mode and OPM mode.
Working in FTTx Mode 14 5 Working in FTTx Mode You can use this mode during service activation (at ONT) or to troubleshoot passive optical networks (at ONT, drop terminal, fiber distribution hub or CO). You can measure two or three wavelengths simultaneously, depending on the configuration of the unit. Selecting a Threshold Set You can select which threshold set will be used to determine the Pass/Warning/Fail status. Your unit contains up to 10 threshold sets, but only one set can be selected at a time.
